Flat solar collector EM2V/2,0 Al-Cu SLIM

Category: Flat solar collectors

EM2V/2,0 Al - Cu SLIM - Flat collector with meander absorber made of copper and aluminium, designed for vertical mounting.

Ensol solar collector EM2V/2,0 Al - Cu SLIM is designed for changing energy of solar radiation into useful thermal energy used for providing warm service water, heating swimming-pools or supporting a heat source in a heating system.

Collector’s housing construction is based on a rigid new, slim frame bent from a special aluminium profile patented by ENSOL company. The new design is a response to the market demand for innovative products.

At the bottom, the housing is closed with an aluminium sheet, whereas the cover is made of a special, high-transmission solar glass. The manner of fixing the glass ensures tightness of housing and minimizes thermal tensions.

The main part of the collector is an absorber, the plate of which is made of aluminium sheet covered with a high selective coat in order to ensure a high level of solar radiation absorption, which results in obtaining high efficiency of the energy conversion process. The absorber’s plate is connected by means of laser welding with the copper tubes system, in which the medium circulates.

Heat losses were minimized by application of lower and lateral insulation made of mineral wool of low heat conduction. Specially designed assembly sets made of stainless steel are used for trouble-free and secure mounting of collectors to roof constructions with different angles inclination.
