Safe and soft hot gas injection
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.

How the ICSH valve functions
See our animation on the working principle.
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.

ICS pilot-operated servo valves
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.
