Fluid Power World’s parent company, WTWH Media, rebrands as Arrowfly FLUID POWER WORLD’S parent company,
WTWH Media, this month announced it has rebranded as Arrowfly, to unify its 40-plus brands under a new identity. The new name and identity reflect our parent company's transformation from a specialized trade publisher into an omnichannel B2B media, events, and marketing company where professional decision-makers, like engineers such as yourself, gather for trusted journalism, industry intelligence, and high-impact experiences that move their markets forward. Arrowfly serves professionals across three industry networks: Engineering; Healthcare and Life Sciences; and Food, Retail, and Hospitality. The company’s portfolio includes more than 40 vertical media brands and more than 45 industry events, from intimate executive forums to large-scale conferences and expos, all built on the editorial independence, subject-matter expertise, and deeply rooted professional communities that WTWH Media cultivated over two decades. While the name and visual identity are new, everything that has made the organization the preeminent destination for professionals across engineering remains unchanged. For Fluid Power World partners and audience, the rebrand reinforces the strength of our community while positioning the company for future growth and expansion.
www.fluidpowerworld.com
We began our journey back in 2006, when WTWH was founded to launch Design World, the original magazine that started it all. Several brands were soon added to meet the needs of various markets, with focuses on specific technologies, such as motion control, mobile hydraulics, bearings, connectivity, and more. Fluid Power World came a few years later in 2014, and then the ball kept rolling. We began to grow through acquisition and soon, we were no longer an engineering-only media company. We now have brands in the healthcare and food service spaces, where events and digital content are changing the way our company serves its core communities. It’ll continue to be business as usual for me and Fluid Power World content, so don’t look for changes there — but if you’re a connection or subscriber, you will see a new email coming into your inboxes. Please be sure to look for your Fluid Power World emails coming from an email ending in @arrowfly.com. Check those spam folders and save our email addresses so you don’t
miss the latest updates to all hydraulic and pneumatic technology news. As we grow, too, look for more new programming. Stay tuned for our August issue, where we’ll be announcing another new avenue to share content with our community. I’ll wrap up with thoughts from our CEO, Matt Logan, on the name change and where we’re headed. “We built this company by earning the trust of professionals in industries where editorial authority matters," said Logan. “The name is new, but the foundation is the same: editors who speak each industry’s language, events that connect buyers and sellers who would never meet otherwise, and communities that professionals rely on for the insight and intelligence they need to make real decisions. Arrowfly gives us a brand that matches the scale and ambition of what we have become.” FPW

Fluid power is a tech industry
can also control a hydraulic one. The fundamentals of hydraulics and electronics are so similar that engineers from one field easily crossover to the other, as not only are the principles the same, but so too are the schematics. So, let’s change how we approach what fluid power is and what fluid power can do by all agreeing that it’s also a tech industry. We’re way past the pigeonhole of grease monkeys and wizards, but rather, deep into the Industry 4.0 weeds where tech professionals implement the same technologies that are soaring in automation, automotive, and aerospace. But be that as it may, learn as much as you can from those Boomers and Gen X. You never know when the zombie apocalypse era hits, and you’ll be called upon for your fluid power black arts. FPW

COMPONENT FOCUS Josh Cosford • Contributing Editor
FOR THE SAME REASON you should never put your hand on a hydraulic hose to check for leaks, never use traditional hydraulic oil anywhere near a heat or flame source. No, being around a hot ingot or furnace won't give you injection wounds, but a pinhole spray from a 3,000 psi hose can quickly turn itself into a flame thrower. In standard fluid power systems, mineralbased hydraulic oils are the default choice due to their excellent lubricity, common availability, and low cost. However, in high-heat industrial environments, like steel mills, die-casting facilities, and glass manufacturing plants, a standard oil leak can quickly turn catastrophic. The issue leading to my earlier example is that mineral oil can atomize into a highly flammable mist when subjected to high pressure (think pressure washer and not garden hose). To mitigate this risk, facilities use fire-resistant hydraulic fluids, commonly abbreviated as FRHFs. To properly select and maintain these fluids, ISO breaks them down into four primary categories based on their chemical composition and fire-retardant mechanisms. These four categories are generally split into two major groupings. The first are water-based fluids that rely on steam to choke out a fire, while synthetic hydraulic fluids rely on chemically engineered, self-extinguishing compositions. The first category is what we call HFA, which consists of oil-in-water emulsions that feature a very high water content, typically around 90-95%. Although HFA fluids offer excellent fire resistance and low cost, they suffer from very low viscosity and poor lubricity, making them suitable mainly for specialized applications such as mining longwall shields (roof support). I know what you’re thinking … HFA doesn’t seem to line up with Oil-In-Water as an acronym. It’s actually the ISO naming convention of Hydraulic Fluid A-Version. The second category is HFB, or invert emulsions, which feature water-in-oil mixtures containing roughly forty percent water dispersed in oil. HFB fluids offer better lubricity than HFA,

FLUID POWER WORLD • JULY 2026
but they are less common today due to fluid separation issues. The third category is, you guessed it, HFC, and consists of water-glycols, which are the popular workhorse in industrial hydraulic environments. Containing roughly 40-45% water dissolved in glycol, HFC fluids deliver outstanding fire resistance and good low-temperature flow, making them ideal for die-casting and automotive stamping, for example. The final category is HFD, of course, which represents fully synthetic, water-free formulations typically made from polyol esters or phosphate esters. Because they contain no water, HFD fluids provide superior lubrication and high-pressure performance, though they require seal materials such as Viton to operate reliably. Understanding how these fluids prevent Dante’s Inferno-level disaster is fundamental to system design. When a water-based fluid like HFC sprays onto a hot surface, the intense heat instantly vaporizes the water content. This rapid evaporation creates a localized blanket of steam that displaces oxygen, effectively smothering the ignition source before the remaining chemical components can catch fire. Synthetic, water-free HFD fluids operate at the molecular level, and while they can technically ignite if exposed to a continuous external flame, their chemical bonds resist rapid propagation, so the fluid naturally stops burning and
puts itself out once the heat source is removed. Switching your hydraulics from a standard mineral oil to a fire-resistant fluid is never a simple, drop-in replacement, and a baseline course requires understanding three critical maintenance factors. First, because water is a poor lubricant compared to mineral oil, water-based fluids cannot support the same heavy physical loads inside a pump. Pumps must often be operated at lower speeds or reduced pressures to prevent premature internal wear. Second, chemical and seal compatibility must be verified because synthetic HFD fluids, particularly phosphate esters, will aggressively attack standard nitrile seals, causing them to swell and disintegrate. Systems running HFD must therefore be retrofitted with fluorocarbon or Viton seals, which may or may not be easy, so it's best to design the hydraulics with fire resistance in mind. Third, fluid health must be monitored religiously, so be prepared for regular testing to maintain the correct water-to-glycol ratio, because if the water evaporates over time due to system heat, the fluid loses its fire-resistant properties. By matching the correct fluid classification to the operating environment and then ensuring strict component compatibility, fluid power technicians can drastically improve plant safety without sacrificing mechanical reliability.

ENERGY EFFICIENCY Ron Marshall • Contributing Editor
Stop the silent thief: Save money with compressed air efficiency system performance, interpret data, and identify improvement projects with measurable savings. It’s especially valuable for professionals involved in audits, energy management, or system optimization projects. Together, the Fundamentals and Advanced courses give participants a strong foundation for understanding not only where compressed air waste occurs, but how to fix it, and serves as an on ramp for achieving a passing grade on the CAGI Certified Compressed Air System Specialist (CCASS) exam. Of course, training is only part of the solution. Good reference materials are just as important when it comes time to apply what you’ve learned back at the plant. That’s why
many in the industry are looking forward to the upcoming release of the Best Practices for Compressed Air Systems Manual in electronic PDF format. Long considered one of the most respected reference guides in the field, this manual provides practical, field-tested guidance on everything from compressor room design and controls to air treatment, storage, piping, and end use. Having that information available in a convenient digital format will make it easier than ever for plant personnel, consultants, and service providers to access key recommendations when they need them most. In addition, a variety of training materials and technical resources are available through the CAC Bookstore, making it easy for professionals to continue building their knowledge between courses. The bottom line is simple: compressed air efficiency doesn’t happen by accident. It happens when people understand how the system works, where losses occur, and how small changes can produce meaningful savings. Whether the issue is air leaks, pressure drop, inappropriate controls, poor storage, or inefficient air treatment, the opportunity to improve is often much larger than expected. If your plant uses compressed air, there is a good chance money is being lost somewhere in the system. The good news? With the right training and the right resources, those losses can often be found and fixed.
hear it, the steady hum of compressors, the hiss of air tools, the pulse of production. To many, it sounds like business as usual. But to someone who understands compressed air systems, that same sound can also mean one thing: Money leaking away! Compressed air is often called the “fourth utility,” yet it remains one of the most misunderstood and expensive resources in many facilities. Since 1999, the Compressed Air Challenge (CAC) has helped plant personnel, engineers, and energy professionals better understand how to reduce waste, improve reliability, and lower operating costs through proven compressed air system best practices. One of the best ways to uncover those opportunities is through training. The CAC’s Fundamentals of Compressed Air Systems training provides an excellent starting point for anyone who wants to better understand how compressed air systems really work. Participants learn the basics of compressor types, controls, storage, treatment, distribution, end use, and system efficiency. It’s the kind of practical knowledge that can help maintenance staff and plant managers identify hidden problems before they become costly ones. For those ready to go deeper, the CAC also offers Advanced Management of Compressed Air Systems training. This course moves FIG. 1.

FUNDAMENTALS By Josh Cosford • Contributing Editor
Heat exchangers: champions of hydraulic fluid conditioning is maintained at an optimal operating temperature. As oil temperature drops, the viscosity of the fluid increases, making it more difficult to pump, creating higher pressure drop and increasing the chance of cavitation. As oil temperature increases, the viscosity of the fluid decreases, which reduces lubricity, increases oxidation rate and can cause the fluid to varnish. Hydraulic systems use heat exchangers to control oil temperature — and therefore viscosity — within an optimal range, where the fluid has the best combination of properties useful to the components of the hydraulic system. Although a few hydraulic machines can make do without external cooling, such as small, lowduty or load-sensing systems, most require a device to keep oil in its ideal temperature range. This is where heat exchangers come in. What a heat exchanger does is self-explanatory. It will use a fluid such as water or air to transfer heat into or away from hydraulic liquid; very simple. However, the nature in which heat exchangers transfer heat can vary vastly. Liquidto-air and liquid-to-liquid are the two primary types of heat exchangers, and you can imagine they can use air and water, respectively, to remove heat from a hydraulic system. Liquid-to-air coolers transfer the heat from the hydraulic fluid through radiation and convection. The simplest liquid-to-air coolers are radiators that count on the thermal difference between the hydraulic fluid and the ambient air. The rate in which a heat is removed from the oil is factored only by the temperature difference between the air and the oil (higher differential means more cooling) and by the existence of airflow (which is sometimes likely in a mobile application). The basic tube and fin cooler is the most economical method of cooling hydraulic fluid, but is for light duty applications, such as low duty cycle or low horsepower applications.

FLUID POWER WORLD • JULY 2026
They are often very small, such as the type used in a vehicle’s transmission fluid cooler, but in hydraulic applications, they can be sometimes paired with light duty fans to improve efficiency. This type of cooler is small and light enough to be attached to the back of an electric motor to take advantage of the motor’s cooling fan. They’re constructed by forming a copper tube into a snaked web, and then aluminum or copper fins are added to surround the tubes. Heat energy is imparted from the oil, to the tube wall, to the fins and then to the air. The more efficient liquid-to-air cooler is the plate and bar style. It will use thick and deep channels of rectangular aluminum with spans of aluminum fins separating them. The better coolers will come with a rough internal finish to those channels to add turbulence to the moving liquid. Although this technique adds pressure drop to the cooler, it removes heat with more efficiency. The fins on the air side of the cooler can also be crimped for a rough finish, increasing air turbulence and improving the rate of heat transfer to the air. Regardless of liquid-to-air cooler construction, any design will more rapidly remove heat
with the addition of convection. Adding a fan to a cooler increases cooling exponentially. Cooling fans can be any size, from tiny dc fans used in the computer industry, to high horsepower ac motors used in industrial applications. Extreme duty mobile applications using dc fans can pull upwards of 40 A, which is the upper range of reasonable usage for 12 V applications, and is taxing on the electrical system in the best of cases. When mobile applications are severe, the fan motor can be hydraulic. With hydraulic energy, the fan can be high power while using absolutely no electrical current. If massive amounts of heat must be removed from a hydraulic system, air coolers aren’t the most efficient option. Although some electric coolers can remove over 300 hp worth of heat, they can block a commercial doorway because of their unwieldy size. Liquid-to-liquid coolers use water or coolant to remove heat from the hydraulic fluid. Water transfers heat orders of magnitude more efficiently than air, and the same wall of air coolers could be matched in performance by a shell and tube cooler the size of a small bazooka. The problem, of course, is liquid-to-liquid CROSS SECTION OF OIL COOLER HEAT EXCHANGER

Some large variants of the plate type cooler can remove a jet engine's worth of heat, although those versions do require extraordinary amounts of cooling medium. It should be noted that any liquid-to-liquid heat exchanger can be used to warm hydraulic fluid as well as cool it. By simply running hot water or coolant through the cooler instead of cold, heat can be transferred to the hydraulic oil. Most often, hydraulic oil is heated electrically, because using warm water requires a more complex cooling system circuit. Regardless, until hydraulic systems have nearly perfect efficiency, heat exchangers will always be a big part of hydraulic systems. FPW

N MANUFACTURING ENVIRONMENTS, reliability is everything. Production schedules and worker safety all depend on systems operating as intended. While pumps and control systems often receive significant attention during maintenance planning, industrial hose assemblies are frequently overlooked until a problem occurs. Unfortunately, hose failures rarely happen without warning. Small signs of wear can develop into leaks, pressure loss, contamination issues, equipment damage, or complete system shutdowns. The financial stakes are significant. According to Siemens' 2024 "True Cost of Downtime" report, the world's largest manufacturers lose approximately $1.4 trillion annually to unplanned downtime, representing roughly 11% of annual revenue. The report found that the cost of downtime has increased substantially in recent years as manufacturing operations become more interconnected and production schedules more demanding. Industrial hoses play a critical role in transferring liquids, gases, chemicals, steam, hydraulic fluids, and other materials throughout manufacturing facilities. They are designed to withstand demanding conditions, but like any component operating under pressure, they experience wear over time. Exposure to vibration, temperature fluctuations, abrasive environments, pressure surges and harsh chemicals can gradually degrade hose assemblies and increase the likelihood of failure. UNDERSTANDING THE TRUE COST OF HOSE FAILURE When a hose fails unexpectedly, the consequences often extend far beyond the cost of replacing the component itself. Production lines need to be shut down while maintenance personnel diagnose the issue and complete repairs in most cases. Unplanned downtime remains a persistent challenge across manufacturing. Siemens research found that major manufacturers experience an average of 20 unplanned downtime incidents per facility each month, highlighting how even seemingly minor component failures can contribute to recurring operational disruptions.

Even simple inspections performed consistently can help detect abrasion, cracking, leaks, or fitting damage early enough to avoid costly repairs. Documentation is equally important. Tracking hose specifications, installation dates, operating conditions and replacement history enables facilities to better understand service-life expectations and identify recurring issues. This information can support more informed maintenance decisions and improve long-term reliability. INSTALLATION PRACTICES MATTER Many hose failures can be traced back to installation issues rather than product defects. Improper routing, excessive twisting, insufficient support and exposure to avoidable stress can significantly reduce hose life. During installation, hoses should be routed to accommodate movement and vibration while maintaining proper bend radius requirements. Contact with abrasive surfaces should be minimized whenever possible and adequate support should be provided to prevent unnecessary strain on fittings and connections.
By addressing these factors during installation, facilities can often prevent many of the premature failures that lead to downtime and maintenance costs later. MOVING BEYOND A RUN-TO-FAILURE MINDSET A common mistake in industrial maintenance is treating hose assemblies as components that only require attention after a failure occurs. While this approach may appear cost-effective initially, it often results in higher overall costs due to emergency repairs and unexpected production interruptions. Preventive replacement strategies allow facilities to replace critical hose assemblies during scheduled maintenance windows rather than during unplanned shutdowns. For applications where uptime is essential, this proactive approach can significantly reduce operational risk. Training operators and maintenance personnel to recognize early signs of wear further strengthens these efforts. Employees who interact with equipment daily are often the first to notice changes that may indicate developing problems. A SMALL INVESTMENT WITH SIGNIFICANT RETURNS Industrial hose assemblies may represent only a small fraction of a facility's overall
equipment investment, but their impact on operational reliability is substantial. A single failure can halt production, damage surrounding equipment, create safety risks and generate significant maintenance costs. For many manufacturers, the cost of downtime far exceeds the cost of prevention. Recent industry estimates indicate that large manufacturing operations can lose an average of approximately $260,000 for every hour a critical production line remains offline, making proactive maintenance one of the most cost-effective reliability investments available. By adopting a proactive approach to inspection and preventive maintenance, manufacturers can improve reliability, enhance workplace safety, minimize the opportunity for impactful environmental releases, extend equipment life and minimize the disruptions associated with unexpected downtime. In today's manufacturing environment, where efficiency and uptime are more important than ever, proactive hose maintenance is not simply a maintenance task. It is a strategic investment in operational continuity. FPW

FROM SWEEPING W FLOORS TO LEADERSHIP: ROBIN HODGSON STEERS SFP HYDRAULICS INTO ITS NEXT CHAPTER
HEN ROBIN HODGSON LEFT HIGH SCHOOL in the UK, he had a few options: continue onto the higher education route, leave for a Government Student Employee Scheme, obtain an apprenticeship, or drop out of school. He chose the third option, which put him into a life-long career in fluid power as just a teenager. He started his career as an Apprentice Mechanical Engineer working for a privately owned company called K&B Beattie Ltd, in his hometown of Ashington, in the North-East of England. KBB had two entities in Northumberland and Aberdeen, Scotland which supplied hose assemblies and hose and fittings to the oil & gas industry, which was economically booming at the time. Hodgson is truly one of those fluid power professionals who has held every job in the field, starting by sweeping the shop floor, and learning all aspects of the hose business. Before he honed in on sales and business development, he worked as a machinist, CNC machining programmer/operator, hose assembler, in coupling assembly, inspection/testing/packaging, global logistics, onshore/offshore installer/lead, manufacturing and production process, costing specialist, internal and external sales and business development/account management, IT specialist (SAP implementation and ERP/MRP process and trainer), finance and P&L ownership, and finally, management and team building. “Throughout my career, I’ve worked in small companies which have required me to wear many hats, hence the experience in every department of the entire business process, and scaling up and growth initiatives,” Hodgson said.
Earlier this year, Robin Hodgson was tasked with fully bringing SFP Hydraulics into the Roth Hydraulics’ fold.

The impact of people Because Hodgson was so young when he entered KBB, many of those early managers had a great impact on his career and helped shape the professional he has become. He especially appreciates Ken Beattie Sr. and Brian Beattie of K&B Beattie Ltd for giving him a chance with his apprenticeship opportunity. It was there he learned the company values that formed his early working years. Additionally, his apprenticeship manager, Ian Latimer instilled a sense of pride, an unstoppable work ethic, a safety culture (especially for PPE) and quality values for

pany, I ended up playing with the head of Bluewater and the tournament organizer. I won the longest drive competition (by luck rather than design),” Hodgson said. This, ultimately, led to Beattie Jr. then offering him the opportunity to move to the USA and help establish a sales team of a greenfield facility in Houston . “By this time K&B Beattie had been acquired by Phoenix AG out of Germany and, all of a sudden, I was employed by a global German corporate powerhouse. Later, Phoenix was acquired by Continental AG, a $20BB revenue company and I worked for the ContiTech division of Continental which in itself was a $6BB division,” Hodgson said. He would like to give kudos to Peter Neale for helping with temperament on the job. “Peter is also from the UK and he was a long-term Phoenix employee who came to Houston as Managing Director of ContiTech Beattie (where by then I was the Global Sales Manager),” Hodgson said. “He BLADDER ACCUMULATORS FROM ROTH HYDRAULICS.

was the last and most influential manager I worked for. He was multilingual, spoke German and French fluently and was calmness personified — to this day, when I have challenges with team members my wife always says to me ‘Be like Peter Neale.’” Building Roth Hydraulics in the U.S. Hodgson was appointed president of SFP/ Roth Hydraulics earlier this year, bringing the bladder accumulator expertise of SFP together with the piston side from Roth. Now, the company has a well-rounded product line with a team of people wellversed in both technologies. “When you marry the two — piston accumulators and bladder accumulators — you've got the best of both worlds,” he said. “SFP has been playing in the oil and gas channel, but now, we've got the entirety of North America, South America, and multiple channels to get after.” Hodgson has been tasked with integrating the privately owned company into a much larger organization of Roth Hydraulics and positioning it for growth. “That entails retaining our own identity which has made the company successful so far whilst embracing and adopting the new cultures and best practices that have made Roth a global powerhouse and growing the company and positioning us for future success,” Hodgson said. “The most exciting aspect is leading the team through the upcoming

all aspects. “Ian had a serious tone that demanded attention to detail but also a fair and rewarding side when you met those demands,” Hodgson said. Ken Beattie Jr., Managing Director/Owner of K&B Beattie, took a chance on him and moved him into a sales role. “After an unbelievable networking opportunity to go and play golf in Holland and represent the com-

challenges we will inevitably encounter and watching the team grow, learn and pass on the same values and knowledge that I have been fortunate to learn myself over the years.” Hodgson noted that sometimes, the most essential aspects of running a business are the least exciting. “While it may not be the most exciting part of the job, dealing with administrative processes, compliance requirements, audits, reporting, and documentation is essential,” he said. “These activities don't always generate revenue directly, but they provide the foundation that allows a company to scale, operate safely, and maintain the trust of customers, employees, and stakeholders. The exciting projects often get the spotlight, but success is usually built on disciplined execution behind the scenes.” The current transition of SFP to Roth is probably his biggest career challenge to date, but he’s up for it. “Success is not guaranteed. It requires, hard work, determination, difficult conversations, failures, change and learning. But what I have learned over the years is that when goals and objectives are clear, direction is provided, support is provided and information is transparent and open then these are the core values that facilitate that success,” he said. “We will be successful because everyone is working with this mindset and our customers will be the beneficiaries of the process. “This almost feels natural to me — it feels like everything I have done before was geared towards this very role. This is almost the easiest part; it’s simply a change in name and not a change in company. SFP Hydraulics compliments Roth Hydraulics and enhances the Roth portfolio and catalog,” he said. “I would consider it a marriage made in heaven where we can take the best of what we do and add the best of what Roth can do and bring it to North America and across the world and become a familiar and global brand name that people know and trust.” What’s easy here, said Hodgson, is that there are several long-term employees at SFP, like Christine Hughey, Inside Sales Manager, who knows its market, customers and

products like the back of her hands. “Christine has dedicated more than 25-plus years to the accumulator industry, beginning with Olaer USA before joining Parker following the acquisition. She later became employee number one at SFP Hydraulics and has played a critical role in building the company's reputation for customer service, technical expertise, and responsiveness,” Hodgson said. “Her experience and commitment represent the type of long-term industry knowledge that continues to drive success throughout the fluid power sector. “We also have Visu Muga, Head of Engineering & New Product Development, with more than 15-plus years’ experience in engineering and who has worked handin-hand with Christine together across the same companies. They both also joined SFP Hydraulics in the early days,” Hodgson said. “Together they form the backbone of experience and knowledge within the company and are going to be equally responsible for the further development, training of new employees, and growth of the company as we diversify into new industries with the new products. With them at the helm and with the backing of Roth they can now look forward to maximizing their full potential.” A flourishing career and future Hodgson has spent his entire career working in the fluid power space and wants to show how wonderful it is to young people. “Engineering and fluid power is applicable across multiple industries and global footprint,” he said. “It literally moves the world, inside and out!” After his own wonderful experience as an apprentice, he wants to introduce an apprenticeship program at SFP/Roth Hydraulics. “I don’t see apprenticeships as often as I used to and I feel like the majority of the world overlooks this, looking at college or university as the gold standard. But there’s still a need for the hands-on learning,” he said. “I was able to successfully learn a trade, learn invaluable life skills and values all while being paid to do so. Who wouldn’t want that opportunity?” Although the industry has changed over his career with more technology and auto-

mation, the relationship side of fluid power is still strong. Hodgson said it’s still critical to have trust, reliability and the ability to solve customer problems. “Looking forward, I believe we will continue to see increased automation, smarter hydraulic systems, improved condition monitoring, and greater integration of data and diagnostics,” he said. “At the same time, there will always be a need for skilled technicians, engineers, and hands-on problem solvers. Fluid power may not always be visible to the public, but it remains one of the critical technologies that powers industries around the world. The biggest challenge facing our industry is attracting and developing the next generation of talent. That's why apprenticeship programs, mentorship, and hands-on learning opportunities are so important.” But he plans to provide similar opportunities to continue to grow the industry. “Fluid power has given me opportunities I could never have imagined as a 16-yearold apprentice in a small town in Northeast England,” he concluded. “It allowed me to learn a trade, travel the world, build lifelong friendships, raise a family in another country, and lead businesses and teams that I am incredibly proud of. If I could go back and do it all again, I'd choose the same path without hesitation.” FPW
