The high-quality materials used for the construction of the collectors guarantee long-term trouble-free operation and high performance.
Laser welding ensures the perfect thermal transfer from the absorbing surface to the hydraulic frame. All absorbers are tested at 7 and 15bar pressure (2 consecutive pressure tests) for leak control and weld strength.
The insulation consists of high-quality rock wool, specially designed for solar collectors. The sealing materials are EPDM, silicone, and polyurethane mastic for maximum resistance to extreme temperatures and absolute tightness of the collector.
