Copper-Brass and CuproBraze Manufacturing Technologies

CUPROBRAZE – THE TECHNOLOGY OF CHOICE FOR FUTURE GENERATIONS OF HEAT EXCHANGERS

CuproBraze is a heat exchanger manufacturing technology for industrial and mobile heat exchangers. CuproBraze heat exchangers are made using special anneal-resistant alloys of copper and brass.

Fresistances” of CuproBraze:

1. Resistance to elevated temperatures and pressures2.3. Resistance to corrosion

These three resistances add up to durability, reliability and long service life for CuproBraze heat exchangers and, consequentlyhighwa ves.

The excellent corrosion resistance of CuproBraze products is due in part to the

Using high copper content brass alloy for tubes CuproBraze material technology ensures excellent resistance against internal corrosion caused by low quality of coolants.

In a world that is increasingly concerned with service life, recycling, reparability and sustainability, a premium is placed on the durability of components. The excellent durability of CuproBraze has been proven not only through accelerated

experience.

3D-vibr exchangers combined with other structurtechnologies enables to ensure oper
