Fully automated feeding systems for land-based aquaculture
Gentle feed transport and optimal operational reliability
Efficient, gentle and reliable
Daltec develops and manufactures complete feeding systems and control systems for the AQUA industry. Our feed transport system is developed with a special focus on gentle and precise feed handling all the way from the silos to the feeding units and has been continuously refined for more than 20 years to meet the conditions and environment that prevail in the aquaculture industry.
Daltec systems handle feed from the moment it arrives and is filled into silos until it is distributed to the individual departments and fish tanks. The systems can be sectioned so that one main system supplies other systems with feed. We use this to reduce the distance between the silos and the individual feeding points. This increases capacity and reduces the amount of broken pellets and the formation of breakage and dust.
Daltec AQUA systems are built on proprietary and well-proven components, where the focus is operational reliability and low service costs. As part of the control concept, we have integrated Daltec Service Watch, which continuously estimates when it is time for the next scheduled service and thereby also reduces the risk of operational downtime.
Daltec DAC for controlling electric feeders.
Big bags with feed are emptied into storage silos via a separate silo circuit. The feeding system collects feed beneath each storage silo. Both systems are designed for gentle handling, capacity, and flexible installation.
Daltec intake hoppers are developed specifically for handling feed pellets so that breakage and feed dust are kept to an absolute minimum.
Feed transfer between two sections. The Daltec Multimix valve manages which feed is delivered to the underlying section. The design of the valve ensures gentle passage of pellets.
Daltec Multimix feed valves are small computers in themselves. Their function is to open and close for feed portions and monitor both the technology and the feed level in the feeder. The feed valves are designed so that there are no edges at the opening where no hole has been drilled.
Daltec offers both disced cable and chain in several types and dimensions, allowing optimization based on pellet size.
DSM Fish is PC-based. The program is developed to provide a clear overview of feed plans, settings, and technical operations.
The drive units are developed so that the pulling force via drive rings and friction drive is transferred gently to the cable or the chain.
With the DSM Mobile app an up-to-date overview of the feeding and the system’s technical operation is available. In the event of alarms, a clear and distinct notification is given and it is possible to reactivate the automatic feeding.
Sectioned systems protect the feed
By dividing the system’s feed lines into smaller interconnected circuits, significantly reduced distances between silo and feed valve are achieved. This is done by directing the feed quickly via branches and feed valves to the departments where it is needed. The shorter distances through the feed pipes protect the feed and reduce the risk of crushing and feed dust. At the same time, this gives the system higher capacity and fewer operating hours.
Daltec feed intake with seamless passage
Daltec’s intake hoppers are specially designed for handling feed pellets. The seamless passage minimizes breakage and dust. The 24 VDC intake hoppers are electronically controlled regarding dosing and start/stop. The intake is electronically monitored and alarms appear in DSM.

Gentle feed transport with Daltec cable and Daltec
friction drive
The Daltec cable provides gentle transport of pelleted feed. It significantly reduces breakage and dust, improving feed utilization and reducing buildup inside pipes. This improves hygiene and reduces wear since a disced cable or chain is not forced through pipes with internal deposits of dirt.
Both cable and chain systems can be fitted with click-on brushes to optimize hygiene and operation.
Daltec Friction Drive
All Daltec drive units are equipped with a friction-drive wheel. This unique principle transfers power reliably by distributing traction across all discs in contact with the drive wheel. The method provides a gentle, yet powerful drive with low energy consumption.

The Multimix valves are one of the important key components in a Daltec feeding system. The valves have several functions. They monitor the content in the feeder and notify the system when refilling is required. They then open and close automatically so that the feed for the respective feeder is delivered correctly, or feed for other feeders can pass without obstruction.
The risk of dust and breakage is minimal because the pipe is not extended through the valve. The smooth swivel damper ensures pellets meet no edges while passing a closed valve.
In themselves, the Daltec valves are also small computers, each communicating with the system’s main control. This means that the valve continuously sends important information back to the control system.
In addition to monitoring that there is feed in the feeder, the valves also monitor themselves – for example if a sensor should show a fault, or if the built-in motor develops an error.
DAC controller
The DAC control unit can operate up to two feeders.
The display shows active pulse/pause times.
The keypad allows ad hoc appetite tests and calibration of dosing capacity.
Daltec Feed Assistant Online+
Daltec Feed Assistant Online+ is the central control of the feeding system.
Via a network and sensors in the individual feed containers, it ensures that fresh feed is delivered to the locations and that the feed plan is followed.
The control system can be operated either via the built-in display and menu system in the controller or connected to a PC with Daltec System Manager.
Management with Daltec DSM Fish.
Operational reliability and clarity are important factors when controlling a feeding system. The daily operation of a Daltec system can be managed and monitored via the simple and clear PC user interface known as Daltec System Manager. Here it is possible to set everything from feed profiles to quantities and feed types. From the user interface, all data is automatically sent to the central feed control. It then handles the electrical control, coordination and monitoring of all components in the system. At the same time as controlling the feeding system, Daltec DSM also provides an overview of the technical operation and collects historical data related to feeding.
Daltec develops its own software and can adapt it to individual conditions and requirements.
With Daltec DSM Mobile feeding can be monitored and adjusted via your smartphone
Daltec DSM Mobile is an app that functions as remote access to Daltec’s sensor-controlled dry feeding systems with portion feeding. Alarms for possible operational disturbances are clearly displayed.
To enable users to plan the necessary actions as efficiently as possible, the alarms are described in text. It is possible both to clear alarms and to restart the system.
Older Daltec portion feeding systems can also be upgraded with DSM Mobile.
World-class feeding systems
For more than 45 years, Daltec has developed and manufactured feeding systems, and for the past 20 years also for land-based aquaculture. Our in-house software and hardware development ensures competent solutions tailored to aquaculture requirements.
Our core competencies are dry feeding systems for agricultural livestock production and land-based fish farming. The objective is the same regardless of the production of our customers – we aim to contribute to optimal use of resources through systems that transport the feed with minimal energy consumption while ensuring optimal feed utilization.
