• Heat exchanger coils
  • Smaller-diameter copper tubes strengthened with low percentages of alloying elements
  • Withstand highter pressures of CO2 (R744)
  • High strength thermal conductivity
  • Minimise wall thickness and materials


Description

Low-alloyed copper contains small percentages of elements such as nickel, tin, iron or other metals. These alloying elements significantly strengthen the copper tubes. They accomplish this by reducing the grain size in the microstructure thus increasing the yield strength. Tube suppliers report increases in the burst pressure of 20 percent to 50 percent compared to C12200 for the same wall thickness.

Basic specifications

  • Heat exchanger coils
  • Smaller-diameter copper tubes strengthened with low percentages of alloying elements

  • High strength thermal conductivity
  • Minimise wall thickness and materials 

Advantages

  • Cost-effective fabrication and assembly
  • Smaller size, less weight and lower material costs
  • Higher heat transfer coefficients
  • Well suited for new refrigerants
  • Uses less refrigerant
