ECI, February 2015
ECI represents the copper industry in Europe and is also part of an international network of industry associations, funded by the copper industry, whose common mission is to defend and grow markets for copper, based on its superior technical performance and contribution to a higher quality of life. This network is unified by a common brand and visual identity – the Copper Alliance.
No. The system energy efficiency can also be achieved with conventional tubes (such as 3/8 inch diameter tubes) simply by using more tubes and thereby increasing the surface area available for heat transfer. Nevertheless, a penalty is paid in terms of the increased weight of tube material and fin material as well as increased refrigerant volume. In general, if larger diameter tubes are used then a larger coil size is necessary to achieve the same performance and energy efficiency that could be achieved in a more compact system with smaller diameter tubes.
No, they are made from steel coated with a thin layer of copper.
The rectification of defects by welding is not permitted on Class 1 and Class 2 forgings.
