Solar collector Hewalex VARISOL DF 30

Varisol DF 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 Heat Pipe evacuated tubes manufactured by Kingspan Environmental Ltd. ensures particularly high collector efficiency. A distinctive feature of the collector is its modular design.

Applications of the Varisol DF 30 vacuum solar collector

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