"ALTER" series

“ALTER” series

Based on our 45 years of experience, we have designed a unique solar thermal collector that offers maximum solar exploitation, lifetime and unsurpassed aesthetics, ideal for rapid transit systems with high energy requirements.

The ALTER series is available in 2 sizes 2.12 m² and 2.22 m² able to cover every need. It is equipped with a selective aluminum absorber, meander-type copper hydroskeleton, aluminum profile frame with electrostatic painting in RAL7038 and solar, unbreakable safety glass.

The collector has been tested for its performance and reliability in Switzerland (Institut fur Solartechnik SPF, Rapperswil) and has been certified by various certification bodies worldwide such as DIN Certco (Germany), DCL (United Arab Emirates) etc.
