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.
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
See our animation on the working principle.
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.
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.

Part of Danfoss' ICV Flexline™ platform, ICS pilot-operated servo valves regulate pressure, temperature, and ON/OFF functions in refrigeration systems. Incredibly versatile, ICS valves can be used on the high and low pressure sides, in wet and dry suction lines, and in liquid lines without phase change.
ICM motor-operated valves, part of Danfoss' ICV Flexline™, regulate the expansion process in liquid lines and control pressure or temperature in wet and dry suction lines and hot gas lines. Compact and lightweight, ICM valves are easy to handle, install, and service.
The ICV with flanges is available in five sizes: ICV 25 PM, ICV 35 PM, ICV 40 PM, ICV 50 PM and ICV 65 PM.
Part of Danfoss' ICV Flexline™ series, ICLX valves are two-step servo-operated main valves with pilot solenoid valves that are used in suction lines for opening against high differential pressure in industrial refrigeration systems.
