CuproBraze® based brazing furnaces

The CuproBraze® technology is an alternative to aluminum brazing and is growing particularly in production of cars and high-efficiency heat exchangers. The use of high strength copper alloys allows for achievement of a light, durable and high-performance heat exchanger at a  competitive cost. The process is environment-friendly (no lead or corrosive and hazardous substances for etching).

The CuproBraze®  process is mainly used for production of automotive radiators and large heat exchangers for specialized vehicles.

CuproBraze® furnaces provide:

• Low-cost production of light, durable and compact heat exchangers with a lead-free, environment-friendly and atmosphere-controlled brazing process.
• The brazed heat exchangers are clean and do not require washing. The brazing applied is high-strength and corrosion-resistant.
• Many methods of brazing application have been developed.

SECO/WARWICK offers the following furnaces:

• For semi-continuous production: compact dual- and triple-chamber furnaces.
• Continuous operation furnaces for a long-run production process, which enables brazing of various elements – recommended for diversified production.

Furnaces for semi-continuous production
 
SECO/WARWICK produces both dual- and triple-chamber brazing furnaces using the new CuproBraze® technology process.

The dual-chamber furnace has a purging-cooling section and a convection heating chamber.

The triple-chamber furnace is equipped with two purging-cooling sections on opposite sides to improve efficiency. This furnace allows capacity to be doubled at a cost increase of about 30%. Two heating solutions are used: electrical or hot gas radiation pipes. Due to intensive convection, rapid heating of the exchangers being brazed and excellent temperature stability during the brazing process are achieved.


Continuous-operation furnaces

Drawing on the design and production experience of SECO/WARWICK in convection (CAB C) furnaces, we have developed a high-performance furnace with belt conveyor for continuous brazing with the CuproBraze® technology. The system consists of a convection heating chamber, water-jacketed cooling chamber assembly, final air cooling station, and ACCUBRAZE PLC/PC computer control system.

This design enables continuous brazing of loads with different weights and dimensions. The versality of the furnace provides the optimum temperature for each element to be brazed.
