Evaporator controls for a variety of refrigerants and operating ranges
Danfoss offers a range of evaporator controls with thermostatic expansion valves or with electric expansion valves. The valves can be used for a variety of refrigerants and operating ranges suited for food retail applications.
The evaporator controls with electric expansion valves are designed to ensure precise control of the injection of refrigerant liquid into the evaporators to ensure optimum performance and low energy consumption.
The evaporator controls from Danfoss have functions for regulating/monitoring temperature, defrosting, doors, rail heating, light and fan operation.
With remote communication as a part of ADAP-KOOL® refrigeration control system, evaporator controls comprise monitoring and control of display cases and cold rooms including alarm monitoring. The Danfoss electric expansion valves enable adaptive, automatic refrigeration control with no manual setting required. This provides additional energy savings.
