The Evaporative Condenser uses the technology of coils and packing combination for the secondary heat exchange in the same direction of air and water to achieve efficient heat exchanges. The fan and water pump adopt high-quality bearings, and there are no other wear parts. The fan adopts direct-connected structure, without transmission loss caused by pulley structure. Low noise, low failure rate. The bottom of the sump is inclined towards the end of the drain outlet and the PVC filler heat-exchange layer is the hanging structure designs, which can easily remove the sewage and impurities in the sump.
