The counter-current heat exchanger allows the compressed air temperature to be reduced to the required conditions, optimising the downstream process. This is the case for adsorption dryers which prefer moderate inlet temperatures achievable with the WFR. The air temperature obtained is slightly higher than the water temperature.
Cooling compressed air, which is in most cases humid, leads to the formation of condensate, which can be separated by a cyclone FTC or WCS condensate separator installed at the heat exchanger outlet.
FTC separators in our FT series, have an aluminium body and cyclone cartridge and are equipped with an automatic float-controlled condensate drain.
WCS separators have a carbon steel body and a cyclone separator with manual drain.
