CuproBraze heat exchangers are made using special anneal-resistant alloys of copper and brass. Tubes are fabricated from brass strip and coated with a brazing filler material. The copper fins, coated tubes, headers and side supports made of brass are fitted together into a core assembly, which is then brazed in a furnace.

The heart of the CuproBraze production line is the furnace. This is where heat-exchanger cores are brazed in a nitrogen atmosphere. Our Sellacan furnace is a Batch type furnace, which can braze large as well as small type heat exchangers. A CuproBraze brazing furnace is fitted with a forced nitrogen convection-cooling section to cool the parts to 150°C. Nitrogen convection cooling gives the product a bright appearance.

The CuproBraze Advantage

The most important performance advantages for CuproBraze are durability as well as size & efficiency. In addition, CuproBraze is clearly superior for applications that must withstand elevated temperatures without failure.

CuproBraze excels with respect to critical performance criteria such as durability, size and efficiency. It is the manufacturing method of choice in practically every application calling for superior heat transfer in a compact space.

CuproBraze technology is well suited for these applications:

• Radiators

• Heaters

• Charge air coolers (CACs)

• Oil coolers

• CPU coolers. Inverter coolers in hybrid vehicles

• Other heat transfer cores

The technology is ideal for vehicles and equipment such as:

• Heavy-duty (HD) highway trucks

•  Locomotive & Other Industrial Applications

• Construction & agricultural equipment
