REFRIGERATION AND AIR CONDITIONING

REFRIGERATION AND AIR CONDITIONING

The refrigeration and air conditioning industry, due to the particular working conditions of the brazed joints, requires the use of alloys characterised by good strength parameters as well as high resistance to the effects of acids and alkalis. Thus LUT-SPAW recommends the use three component alloys copper – phosphorus – silver and silver – copper – zinc.

Alloys for the refrigeration and air conditioning industry.
