ICSH 25-80

ICSH dual position solenoid valve belongs to the ICV family and consists of an ICV housing, an ICS insert together with an ICSH top cover with 2 EVM normally closed solenoid pilots installed in the top cover. All sizes of ICSH are designed for a MWP of 65 bar. ICSH is used in hot gas lines for the opening of hot gas defrost flow to the evaporator in 2 steps. Both steps are activated by a controller or a PLC energizing the magnetic coils in a time delay sequence. Step 1 (approx. 20% of full flow) is to allow a smooth pressure build-up in the evaporator, while the subsequent step 2 opens the flow to 100% to get the full defrost capacity. The ICSH is designed for large industrial refrigeration systems with ammonia, fluorinated refrigerants or CO2. The ICSH features 2 configuration options First option secures that step 2 can never open unless step 1 has been mechanically activated. Second option is independent configuration that allows step 2 to open disregarding step 1.
