TECHNICAL CHARACTERISTICS OF COPPER HEATER

1. Copper & aluminum are the materials used, ie non-corrosive materials, which ensure a lifespan of many decades. There are no corrosive steel parts.
2. Frame made of heavy-duty oval aluminum profiles, high aesthetics, advanced design, with internal angled die-cast screw aluminum angle joints that ensure the perfect fit & tightness of the frame parts & the large stacker.
3. Absorber selective surface of 0.4 mm thick aluminum foil with special titanium oxide coating. The coating is done by special vacuum treatment in Germany. The surface of absorption of solar radiation is perfectly applied on the copper hydroskeleton by welding in automatic LASER machines for direct transfer of heat to the thermal liquid. This ensures a very high absorption coefficient α> 95% & a very low emission coefficient ε <5%, which contribute to the maximum thermal efficiency of the collector.
4. Foil collector that ensures complete tightness against the frame without rivets.
5. Hydroskeleton absorber made of copper pipes Φ8 & Φ22 mm
6. Safety glass tempered 4 mm thick with high permeability τ> 0.94.
7. Thermal insulation from fiberglass density d = 30kg / m3 both at the back and sides of the collector.
8. Oval rubber gasket of special design adapted to the copper connecting pipes of the collector to prevent heat bridge between the frame and copper pipes due to thermal contraction and expansion.
