Solar collector Hewalex Thermomax DF 400 30

THERMOMAX DF 400 30 evacuated tube solar collectors represent the premium segment of solar collectors, being among the most powerful units of this type on the market. The use of single-wall evacuated tubes manufactured by Kingspan Environmental Ltd ensures particularly high operating efficiency. The THERMOMAX DF 400 30 collector can also be installed in challenging conditions, such as vertically on a façade.

Possible applications of the vacuum solar collector THERMOMAX DF 400 30

The THERMOMAX DF 400 30 vacuum collector is equipped with 30 65mm diameter vacuum tubes. Heat from the absorbers is directly absorbed through the glycol flowing in the concentric tubes. The collectors are designed for use in both small and large solar panel systems. High efficiency at high temperatures is achieved.
