This group of heat exchangers are mainly coolers of electric motors, but also coolers of compressors, exciters, generators, etc. Due to the fact that the refrigerant in this type of coolers is water, their pipe inserts are made of ribbed pipes based on stainless steel, brass, copper pipes and copper pipe as well as cupronickel pipes.
Collectors and sieve bottoms in this type of cooler can be made of black steel protected from corrosion by BELZONA type special ceramic coatings or they can be made of stainless steel.

Our company’s offer includes coolers built on the basis of structures of existing designs as well as coolers which are the modernization of the existing units with the maintenance of the overall dimensions necessary for trouble-free installation of the cooler on the premises.

These coolers are characterized by better thermal properties with less refrigerant volume and less weight of the entire cooler. Below we present photos of sample implementations.
