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.

Features and benefits

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

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.
