HWR

HWR heat recovery coil in which surplus heat, e.g. from refrigerators, can be used to heat the supply air.

HWR, construction

Function and application

This coil has been specially manufactured for a so-called shop solution, in which surplus heat from refrigerators etc. is recycled. This means that surplus heat from refrigerators can be used to heat up the supply air.

The water is supplied through pipes which exit the unit at the front. The number of pipes and circuits depends on the applicable heating or cooling requirement.


Construction

HWR coils are made from copper piping with aluminium fins integrated in steel panel frames.


Connection

Pipe connections and panels must be dismounted prior to pulling out.

Design options

Heat recovery coils are available in different versions with several coil combinations.
