Dolphin Manufacturing Line offers both soldered copper-brass and brazed copper-brass – CuproBraze heat exchangers for mobile and industrial applic ons.
SOLDERED COPPER-BRASS TECHNOLOGY
Soldered copper-brass technology is a v v avy diesel reparability. High nobility of copper and brass alloys ensures good resistance against general corrosion and stress corrosion cracking (SCC). CuproBraze oys with the
reliability and ex r even at the harshest oper n drag and superior heat tr to-volume r exchanger. This ensures that product design engineers do not need to make any compromises with respect to cooling system weight, cost, size and durability. 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.
F resistances” of CuproBraze:
1. Resistance to elevated temperatures and pressures 2. 3. Resistance to corrosion
These three resistances add up to durability, reliability and long service life for CuproBraze heat exchangers and, consequently highwa ves.
The excellent corrosion resistance of CuproBraze products is due in part to the
Using high copper content brass alloy for tubesCu proBraze 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.
