Frequency inverters | Our products
Stable uniform control of your fans is important, as is reducing energy consumption. By using a Danfoss variable speed drive, the energy consumption will decrease to the 3rd power when down regulating to its performance, without sacrificing stable control. By applying an additional coating (standard for our AC drives), the VLT AC drive is suitable for agricultural applications.

Controllers | Our products
Climate control in animal housing is vital for your animals. Values such as minimum and maximum
ventilation rates, whether or not combined with temperature control and heating control, can be controlled using everything from the simplest controllers to the most advanced climate computers. Combining these with the right end stations, such as frequency converters, also prevents excessive energy consumption. We are happy to advise you on the right choice of controller.

Climate controller CBA
The CBA controls the climate in one department and is equipped with two displays that allow the temperature and ventilation to be read at a glance. Depending on the application, the CBA is available with a 0-10V output or with a 230 Vac triac control. Because of the growth curves present, the climate grows along with your animals.
The controller regulates the barn climate in such a way that the correct ratio between heating and ventilation is always guaranteed. Furthermore, it is possible to control several fans in two groups. If the ventilation demand exceeds a certain level, the second group of fans is automatically switched on regularly.
Fan controller MFC
The fan controller MFC controls the connected fans in such a way that the set temperature is maintained. The temperature is measured by means of the supplied temperature sensor that must be placed in the room.
The controllers are equipped with internal fan voltage stabilization. This makes the set minimum fan voltage insensitive to mains voltage variations. This is especially important if the controller controls heating in addition to ventilation. Furthermore, each MFC is equipped with a mains switch with an override position that allows the fans to be switched directly to the mains in case of an emergency.
Fan controller ASR-10
This controller is designed to control servo motors, frequency converters, and power controllers that require a control signal of 0-10 V. It is used to control ventilation and heating. An internal setting is used to select a signal that increases in proportion to the temperature, or an output signal that is corrected for the characteristics of a rotating air damper.
Ventilation controller NVR
The NVR controls the ventilation valves or curtains based on the set temperature. If the barn temperature falls below the set value, this controller ensures that the valves or curtains close further. In the event of a temperature increase, the opposite occurs.
De NVR-1 is toe te passen op een motor zonder positieterugmelding. Met behulp van de 'delay-knop' geeft u het klimaat de gelegenheid zich aan te passen aan de nieuwe situatie. Bij een plotselinge temperatuurdaling van 2 °C of meer (dit kan voorkomen bij opkomend noodweer) wordt de ventilatieklep of het gordijn versneld gesloten.
Multifan electric manual controller EW

The T15-4 mechanical thermostat, in combination with an MF-Net transformer, enables temperature-controlled regulation of fans. The thermostats in the T15 series are for single-phase applications.
Advantages:
- Low investment costs
- Easy installation
- Easy operation
- Durable and robust

Pressure regulator DPA
This pressure regulator is designed to maintain a set underpressure or overpressure in a central extraction duct or in air-conditioned rooms. The regulator has a switched pressure output with adjustable hysteresis and delay time.
The DPA-300c has a 0-10V output that is controlled by a PI control characteristic. This makes the DPA-300c ideal for controlling inlet valves in ventilation systems. Control and regulation are carried out by a climate computer with negative pressure control or by a terminal station (manual-0-automatic for negative pressure control and time control (available on request).
Clock controller CLK
The CLK-8 and CLK-20 clock controllers have 8 and 20 clock functions respectively, to which a 0-10V output or a switching contact can be assigned, depending on the number of available outputs.
Thanks to their extremely simple operation, users can easily program lighting control with different start/stop times and dimming cycles.
Universal Digital Thermostat
The UDT, Universal Digital Thermostat, is a processor-controlled controller. This controller is the solution for ‘simple’ control engineering problems. The UDT types with standard software are in stock in our warehouse.
If desired, the UDT can be adapted to the desired number of inputs and outputs and provided with customized control software.

End stations | Our products
End Stations
If additional inputs or outputs are required for the climate computers, end stations can be connected via a bus system or 0-10V output. These end stations are also equipped with a manual-0-automatic switch, allowing for manual operation when needed.
End Stations and Expansion
Modules
We offer a variety of end stations in our product range, including options for servo motors, valve actuators, timer switch functions, and manual operation. You can find more information about the different types in the brochure.
DIN-Rail and built-in modules
With our DIN-rail and built-in modules, you can configure control panels according to your specific needs. For "in-cabinet" versions, please refer to the documentation under "End Stations and Expansion Modules."
Auxiliary Equipment for Climate Computers
A weather station is used with climate computers to measure wind speed, wind direction, or rainfall. Sensors such as a wind vane, anemometer, or rain sensor are connected to the PL-METEO unit, which communicates with the climate computers. The PL-MWA is the combined wind vane and anemometer with mounting bracket.
To measure humidity in the barn, the RH-160 or FB80-10 humidity sensor is used in conjunction with the climate computers. The computers can also utilize measured CO₂ levels for control purposes. The CS-02 CO₂ sensor measures the CO₂ concentration and sends this signal to the climate computers for processing.
Single-phase power controllers
The power controllers are ideal as end stations for controlling fans (230V) or lighting. During normal operation, the control signal is supplied by an external controller. It is also possible to manually adjust the power using a rotary knob. For controlling higher power levels, multiple power controllers can be connected to the same control signal.

AQC Air control unit
Thanks to the excellent aerodynamic properties of the measuring fan and the control valve (available in two- or four-way versions), the AQC unit enables highly reliable ventilation control. In combination with a Stienen climate computer, the AQC unit can be used as a measuring and control unit in a central exhaust system, or as a measuring and throttling unit beneath ventilation chimneys. Ventilation capacity can be regulated starting from 0.4 m/s with this unit.
The AQC unit is supplied as standard with a unique plug connection, ensuring trouble-free installation. The measuring fan is equipped with an ingenious labyrinth design that protects the rotating parts from dust and dirt, guaranteeing a long service life.
Connection materials for AQC valve
The AQC unit is supplied as standard with a unique plug connection, ensuring easy and reliable installation. For connection to a climate computer, standard cables and connector boxes are available..
In some cases, the distance between two or more AQC valves may be so great that ventilation differences occur between them, especially when only one valve is equipped with a measuring fan. If this ventilation imbalance is undesirable, the (discontinued) AQC split box offers a solution.
Measuring fan SMV
The SMV measuring fan reliably measures the volume of air moved through a ventilation chimney. Its unique design ensures that a pulse signal is only generated when the airflow is moving in the correct direction. This allows the climate computer to trigger an alarm if airflow is detected in the reverse direction
The aerodynamically optimized plastic impeller enables precise measurement of airspeeds starting from 0.4 m/s. The double-bearing shaft and high-quality ball bearings are made of stainless steel. The electronics are fully encapsulated in casting resin, making the SMV a measuring fan that continues to function reliably even under the harshest conditions.
