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 optionsFirst option secures that step 2 can never open unless step1 has been mechanically activated. Second option is independent configuration that allows step 2 to open disregarding step 1.
Features and benefits
- Designed for Industrial Refrigeration applications for a maximum working pressure of 65 bar / 943 psig.
NOTE: Operating valve MWP is dependent on MWP of installed pilots - Direct welded connections
- Connection types include butt weld, socket weld and solder connections
- Low temperature steel body and service friendly design
- Low weight and compact design
- 2-wire connection for use with a timer relay or 4 wire connection for connecting to a controller or a PLC
- The ICSH main valve top cover can be oriented in any direction without the function of pilot valves being affected
- Stabilizes working conditions and eliminates pressure pulsations during opening of hot gas
- Manual opening possible
- PTFE seat provides excellent valve tightness
ICSH Flexline™ dual position solenoid valve
Hot gas defrost is a very common and efficient method used within industrial refrigeration. Sound design practices and specific design features should always be considered carefully to prevent safety risks, which may be caused by even a slight change in operating conditions.
If not controlled carefully, the injection of hot gas into the evaporators may cause hydraulic shocks in the refrigeration system and represent a safety risk. Therefore, it is important to make the hot gas injection in a controlled and smooth way to ensure maximum operation and system safety.
Product Highlights
- Improved safety
- Complies with latest IIAR safety recommendations on soft gas applications
- Easy to upgrade and install as it is fully compatible with Danfoss ICV platform
- Easy system design with the Coolselector®2 application tool
- Saves space thanks to its compact design
ICSH for safe gas injection
Dedicated for the hot gas line, the Danfoss ICSH valve ensures a controlled, 2-step injection of hot gas into the evaporators. The dependent configuration of 2-step opening helps prevent negative pressure impact to your refrigeration system.
Based on the Danfoss ICV platform and built-in design flexibility the ICSH dual position solenoid valve is backwards compatible with Danfoss ICS & ICF large valves.
Improved safety for hot gas injection
The ICSH Dual Position Solenoid Valve is designed for gradual and safe opening of the hot gas flow to the evaporator, featuring an extra-safety-configuration to prevent hydraulic shocks in the system.
