Induction heating - brazing of refrigerator parts

Appliances

EFD Induction supplies induction equipment to the world's leading producers of refrigerators, freezers, dishwashers, washing machines and faucets.

White goods like dishwashers and washing machines contain numerous heating elements that require brazing. Likewise, refrigerators and freezers contain many compressor parts that need to be brazed. Induction heating is also used for brazing faucets (tube to the socket, thread insert). Since induction heating is accurate, controllable and repeatable, you get strong, leak-proof and corrosion-resistant joints.

 

Our solutions for brazing white goods typically include parts such as:

•Tube-to-tube with sleeves

•Condenser with capillary tubes

•Tube-to-block in distribution systems

•Tube-to-valves in distribution systems

•Compressor connections

 

Induction brazing is easier than traditional gas flames methods. You don’t need insulation shields. The work process is faster and the risk of error lower. Moreover, contemporary white goods include number of plastic parts that are sensitive to melting, further promoting the use of induction.

Brazing is not, however, the only use of induction heating in the white goods industry. Induction is also used for the hardening of compressor parts, shrinking of other parts and bonding of fridge bodies as well as paint curing and tube welding.
