Solar Collector Atmosfera CBK-А-20

Diameter condenser heat pipe - 24 mm)
collector CRS-A effective for use all year round in any
region of Ukraine. Collector efficiency - 95%. It has high performance in terms of low solar insolation. Insulation of the heat exchanger 75 mm. Aluminum collector frame allows to reduce the load on the supporting structures of the roof. The universal frame structure is designed to fit to any type of collector roof from horizontal to vertical surfaces
