EXHAUSTOProductsModular unitsVEX4000, modular air handling unitsHeat recovery coil (HWR) HWR HWR heat recovery coil in which surplus heat, e.g. from refrigerators, can be used to heat the supply air. Merge to pdf 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. VEX4000 HWR 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.
