to a liquid state and then is passed through an expansion valve to an evaporator coil to absorb
heat and change the refrigerant back to a gaseous state for' recompressing in the compressor
to complete the refrigeration cycle. The evaporator coil is positioned within a refrigerated box,
display case, or cabinet and the heat absorbed by the refrigerant passing through the coil
serves to extract heat from the refrigerated box and its contents to maintain the box at the
desired temperature. As is well known, this extracting of heat from the refrigerated box' and its
contents causes fros't to form on the evaporator coil and refrigerated box which periodically
must be removed to maintain proper functioning of the evaporator coil and avoid undesirable
build-up of frost on the coil or other parts of the refrigerated box.
There are two types of desuperheater provided by Maniks


Freon Desuperheater - SERIES HEF 33- XXX- 22
