LIFE IS EASY THE KELVION SELECTION PROGRAM

The Kelvion selection program provides an electronic catalogue covering the majority of product ranges offered by Kelvion. The range of products available to you is very broad with many options. This software provides the fastest and easiest way to select the most appropriate product for your specific needs. This selection program run on the latest versions of Windows (including both 32-bit and 64-bit versions of Vista, Windows 7, Windows 8 and Windows 10). All four product types (Coolers, Condensers and Glycol Coolers) are available in a single program. The Kelvion selection program is an easy to use selection tool for contractors, consultants and every other thinkable user and gives you access to many advantages such as: • Multilingual • Pre-select buttons to application • Spare parts • Selections including drawings • An extensive list of accessories • Accurate capacities: During your selection a sophisticated capacity calculation program optimizes the circuits to the design conditions • Selections possible on several criteria such as capacity, price, fan variations like noise and speed etc.

Kelvion selection program. This will make the selection faster and exclude models which may not be relevant for your needs. You can start a selection by clicking the Start button, fill in the required heat exchanger data in the input area and produce PDF or Word files of your selection results. Also it is possible to print a drawing of the selected unit and make your choice belonging to your selected unit. The program normally operates using SI units. What is important to you? - You can decide which features of the product are most important for each application: energy efficiency, footprint (physical size) and price. You adjust the slider controls to indicate the relative importance to you of each of these three elements. You can also choose to display all possible models, or just the ‘top 10’ which best meet your selection criteria. Once the selected models are displayed, the ‘best’ options in each category (energy efficiency, footprint and price) will be on top of the table. Quality, Support and Website - Trained staff will advise you through every step of the selection process.

KELVION CU/AL ST/AL – STST/STST SERIES STANDARD CUSTOMIZED

INNOVATION

For all StSt/Al and StSt/StSt models and series of the Kelvion air coolers your schedule of requirements is leading. Depending on the application, our sales team searches for the optimal configuration in close cooperation with the customer. You have a free choice in the so-called level 1 and 2 versions: • dimensions • Air direction • blow-through or draw-through • model: with feet of suspension profiles • cooling system: natural (NH3 and CO2) and synthetic refrigerants • materials: copper tubes/aluminium fins, Stainless steel tubes/aluminium fin, Stainless steel tubes and fins or steel tubes and fins / hot dipped galvanized • accessories: eg defrost, coatings

We can not emphasize often enough that we can meet our “customized production” philosophy to every customer requirements. Common customer requirements lead to innovation of our products. A good example is the energy efficient Kelvion VRe range in the stainless steel / aluminium version of our air coolers and air-cooled condensers

LEVEL OF ENGINEERING ‘FLEXIBLE CUSTOMIZED’ The custom-made cooling systems built from standard product components are so-called “Level 2 Flexible products”. Within this level of engineering, you can choose from air coolers consisting of copper tubes with aluminum fins (Cu / Al 50x50), stainless steel tubes with aluminum fins (St / Al 50x50), stainless steel tubes and fins (St/St / Al 50x50) and hot dipped galvanized steel tubes and fins (FeZn 60x60). 8

FAN SYSTEM

SPECIFICATIONS

Because of the flexible construction of the Kelvion air cooler, in principle it is possible to deliver with different fans. We selected a standard fan range of Ziehl Abegg and EBM (we reserve the right to alter the manufacturer) which fits perfectly on the Kelvion flexible air coolers. The fans can be supplied in both blowthrough and draw-through executions. Against an extra price stainless steel guards and EC-fans are available.

Fan data 1x230V-AC 3x400V-AC 1x230V-EC 3x400V-EC

Fan execution The fans meet the ErP2013 directive. The fans have very good aerodynamic features because of the special impeller geometry. This special impeller geometry gives the fan a low noise level and a high efficiency.

Tension : 1x230V-50Hz (60Hz on request) : 3x400V-50Hz : 3x400V or 3x460V-60Hz Protection class : IP44 / IP54 Color : RAL9005 (black) Speed controlling : 3 phase : 2 speeds by D-Y reconnection : frequency controller with all-pole sinus filter : 1 phase : phase-control : transformator

: till -25°C environment temperature : till -40°C environment temperature (between -40°C en -50°C environment temperature on request) : till -25°C environment temperature : till -35°C environment temperature

SOUND DATA The mean sound pressure (LpA @ 3m ± 2 dB (A)) each air cooler is a calculated indication value according to the EN13487 standard parallel pipe. Kelvion uses the fan manufacturer’s sound power level (LwA) at the inlet side of the fan. Changes to or by the fan or the product, affect the sound, in these cases consult the manufacturer for the new indication value. In critical sound requirements, we advise you to consult an expert.

correctiefactor correction factor

The maximum allowable working data in the table and on the name plate of the fans are to operate in an air temperature of +20 °C (air density of ρ = 1,2 kg/m3). For air temperatures lower then +20 °C, the current amperage can be calculated by using the diagram multiplication factor, suitable thermal overloads can then be selected. In our Kelvion GPC selection program also the values in the working point are indicated.

For room temperatures where ice-build up can be expected and where the coil can not be defrosted by the room air, an defrost system is available. Electrical defrost On request Kelvion Flexible air coolers Cu/Al can be provided with electrical defrost. A distinction can be made here between heavy defrost loads for low temperatures and light defrost load for higher temperatures (room temperature approximately 0 °C).The stainless steel heating elements are fitted in the coil block within aluminium tubes, which forms a highly conductive medium between the heaters and the fins. In the drip tray heater elements are fitted to the underside of the aluminium inner tray. The elements are rated for 220/240 V and are connected (IP55) for 380/415 V (with neutral) supply. The heater elements in the coil block are removable from the bend side, whilst the tray heater elements can be removed once the outer tray has been removed. The exact number of elements and electrical power for light and heavy defrost each air cooler, you can find in our Kelvion selection program.

Heating section The air cooler can be carried out with a heating section with electric heating elements to heat up again dehumidified air The heating section is compared to the air flow placed after the coil block. The heating elements can be placed with holders against the coil block or completely integrated in the casing. Hot gas defrost The coil block is as standard suited for hot gas defrost ( hot gas supply through the suction header). Against an extra price the drip tray can be provided with a copper hot gas spiral. This is enclosed in aluminium profiles that are rigidly secured to the under side of the aluminium inner drip tray. As a result, a very good heat transfer is realized. As with electric defrost a distinction is made with light defrost (room temperature around 0 ° C) and heavy defrost. Water defrost On top of the coil block a removable water defrost tray is mounted. The height of the water defrost tray is 80 mm, which increases the total height of the air cooler. The standard discharge head of the water in the water defrost tray is 25 mm, the maximum speed in the water supply line is 5m / sec. For an optimal functioning of the water defrost, the temperature of the defrost water must be between + 15 ° C and at + 30 ° C. The water defrost tray is executed with handles, easy for disassemble and cleaning.

FAN HEATING

The fan fan heating prevents ice build-up between the fan impeller and fan bellmouth during the defrost cycle. This prevent damaging of the fan. We advise to use fan heating as option on your air cooler when the room temperature <-10 °C Delivery • Is mounted and connected to a junction box • Can also be retrofitted
