Copper Tubes For Heating Application & Solar Panels :
The copper tube we manufacture finds numerous applications in Heating and Solar Panels. For steam-heating systems, especially return lines, the outstanding corrosion resistance and non-rusting characteristics of copper tube assure trouble-free service and maintenance of traps, valves and other devices.
We recommend our copper tube for heat exchangers and condensers because copper''s inherent superiority in thermal conductivity, corrosion resistance and strength has made it a preferred primary metal for Heat exchangers(radiators) and condensers since the dawn of cars and trucks.
Copper Tubes (Air Conditioning Systems And Refrigeration Systems) :
The Copper tubes that we manufacture are extensively used in Air conditioning systems. The use of copper tube in air-conditioning and refrigeration systems has grown steadily in recent years. This is in large measure due to the inherent properties of the copper metals and their unique abilities to meet the needs of the ACR industry. Stringent new requirements, including demands for increased operating efficiency and the reduction or elimination of harmful emissions, have led to a new appreciation for copper tubes role in product enhancement.
