Another application example from air conditioning technology is a condenser for an air conditioning unit.

A detailed photo of the copper pipe bend is shown. For brazing this connection, flame brazing can be used or alternatively, depending on the working material, furnace brazing with an inert gas. For copper to copper brazing, the phosphorus-containing BrazeTec Silfos 2 brazing alloys with a working temperature of ca. 740°C and BrazeTec Silfos 94 with a working temperature of ca. 760°C can be used.

For copper to copper brazing work, no additional flux is required due to the phosphorus content.Kupferlötverbindung

BrazeTec Silfos brazing alloys can be used down to temperatures of -50 °C in the refrigeration industry.
