Chiang Mai Solar manufactures solar absorbers by hand from solid copper sheets and pipes.

Highly skilled workmanship combined with German Engineering results of the finest quality and highest efficiency.

Copper has one of the highest heat transfer rates and the absorbing ability of our copper panels reaches an efficiency of almost 0.95 (95%).

High grade pure copper sheets be cut to size, the edges are bended and braced to the copper liners. The finished absorber fins are shaped and assembled to collector panels.

The copper surface is treated with a black oxide coating to enhance IR absorbing ability and protect oxidation.

The absorber housing is build from extruded and anodized aluminium profiles, well insulated with PU foam and rock wool. The glass cover is from tempered safety glass to insure highest stiffness against mechanical impacts.

Service minded and highly innovative we can manufacture any customer specific design.

The stainless steel tank is manufactured by hand from high grade SUS304.
Welded by well experienced engineers, every tank is tested with a test pressure of 5 bar. Well insulated, the tank keeps the hot water for several days. The tank is insulated with two layers, a 10 mm PU foam layer and a 75 mm rock wool layer with aluminium foil cover.
All pressure systems are equipped with a pressure relief safety valve. Large tanks with forced circulation are also equipped with a circulation pump and temperature sensors. An electric backup heater is optional.
