Cupori Group brings out cleaner copper tubes

Submitted by Baerbel Epp on September 17, 2008

The Finnish company Cupori Group Oy, which in the spring took over the copper business of Outokumpu Copper Tube, now supplies a copper tube with a particularly clean surface. At the Intersolar 2008 in Munich in June the company presented its new “Tub-e” copper tubes, although still under the old name. They are claimed to have a particularly clean surface thanks to a thermal cleaning process. According to Cupori, welding times during absorber manufacture are shorter with the new tubes.
