Flat collector ES2V/2,0S-AL

ES2V20Al

ES2V/2,0S AL – flat solar collector with meander absorber, made entirely of aluminum, designed for vertical mounting.

Aluminum collector ENSOL ES2V/2,0S AL  is designed for the exchange of the solar radiation energy to thermal energy applied to prepare warm domestic water, for heating of water in swimming-pools or for the support of the warmth source in the heating installation.

Collector’s casing construction is based on a rigid frame bent from the special aluminum profile patented by ENSOL company. At the bottom the casing is closed with aluminum sheet, whereas the cover is made of special, high-transmission solar glass. The manner of fixing the glass ensures tightness of casing and minimizes thermal strain.
