Technical data
The coils are specially designed to operate in the aggressive environment of high humidity and temperature fl uctuations that you fi nd in most refrigeration systems.
The new Clip-on fastening system ensures a faultless installation and makes the coils easy to mount and dismount. A Danfoss Clip-on coil can be mounted without any tools at all, and it is simple to dismount the coil by means of a screwdriver.
The Clip-on coils are available for the entire range of Danfoss solenoid valves for refrigeration, freezing and air conditioning
