Application
The controller and valve can be used where there are
requirements to accurate control fo superheat and temperature
in connection with refrigeration.
E.g.:
• Processing plant (water chillers)
• Cold store (air coolers)
• A/C plant
Advantages
• The evaporator is charged optimally – even when there are
great variations of load and suction pressure.
• Energy savings – the adaptive regulation of the refrigerant
injection ensures optimum utilisation of the evaporator and
hence a high suction pressure.
• The superheating is regulated to the lowest possible value
at the same time as the media temperature is controlled by
the thermostat function.
Functions
• Regulation of superheat
• Temperature control
• MOP function
• ON/OFF input for start/stop of regulation
• Input signal that can displace the superheat reference or
the temperature reference
• Alarm if the set alarm limits are exceeded
• Relay output for solenoid valve
• PID regulation
