VACUUM-TUBE SOLAR COLLECTOR, 16 PIPES

Unique reflex construction of complex parabolic mirrors through which collector efficiency is highly improved by solar energy accumulation all through the year.

Operation principle: sunrays are absorbed at such an angle of incidence as to ensure that collector receives directly the solar irradiation all day long. The lower and not directly irradiated arc of collector tube is being irradiated by solar radiation through the parabolic reflector. Thanks to its unique construction the solar collector by ELDOM has 30% higher thermal efficiency compared to other evacuated tube collectors. This collector construction results in self-cleaning from dust and snow which additionally guarantees their maximum efficiency throughout the whole year.
– Evacuated tube heat pipes with a three-layer selective coating. The deep vacuum in pipes protects the absorber from “ cooling down”, thus way collector maintains its efficiency also in lower outside temperatures;
– Higher thermal insulation – insulation thickness is 50 mm, from high quality rock wool. Provides for very low heat losses and high thermal resistance of product;
– Silicone contact thermal grease, to improve the thermal transfer between the heat pipe glass tube and collector heat exchanger;
– Maximum catching and absorption of solar /ray/ energy thanks to the parabolic concentrators;
– Heat pipes made from copper to ensure a better heat exchange;
– High temperature resistance;
– Exceptional absorption characteristics, with lower heat losses, specially adapted for operation in cold weather too;
– Excellent resistance to corrosion and longer life;
– High absorption ability;
– Pipe glass made from high quality borosilicate material, 3,3mm thick;
– Resistance to hailstorms of ice grain diameter up to 25mm.;
– Specially designed holders to protect collector from snow banked up and help its self-cleaning.
