The Solahart Bt collector is designed to generate maximum performance in every possible climatic conditions. The Ultra-high efficiency absorber with its blue sputtered selective surface maximizes the absorption of the sun energy while minimising emission (heat loss). The collector can be used in closed circuit as well as open circuit systems.
The Bt collector is designed to connect multiple collectors easily to each other to create a large collector field and it can be used in any type of solar system. One of the applications where Solahart is using the Bt collector is the revolutionary commercial drain-back pumped Solahart Heat Store Series II systems.
The Bt collector has been tested at ITW Germany, test nr. 04COL339 and certified by DIN CERTCO reg.nr. 011-7S012F.
