Fan speed controllers

Fan speed controllers help stabilize condensing pressure by changing condenser fan speed in refrigeration and air conditioning units. In cold room systems, they are relevant where stable condensing pressure, lower fan noise, and improved performance in changing ambient conditions are important. They are used in walk-in coolers and freezers as well as in broader refrigeration and air conditioning applications operated throughout the year. The category includes controller options for different motor and installation needs, including solutions for single-phase, three-phase, and EC fan motors.

Controllers and drivers for stepper motor valves

Superheat controllers are used to regulate evaporator superheat and control stepper motor valves with high precision. They help optimize evaporator charge, support stable operation, and improve system efficiency by regulating superheat to the lowest possible level within a short period of time. In cold room applications, superheat controllers are part of the wider control layer of the refrigeration system and are included in the cold room portfolio. Beyond cold rooms, these controllers are also used in air conditioning, commercial refrigeration, food retail, chillers, heat pumps, transport cooling, and other refrigeration and HVAC applications.
