Bench of boiler a granulates

DESCRIPTION

The bench of study of a boiler with pellet is delivered, instrumented with technical and teaching handbook.

It is composed of a boiler OKOFEN 8Kw with condensation, of a hot water domestic network, a heating network high temperature and can in option being equipped with a network low temperature to highlight the advantages of a boiler at condensation.

A silo out of fabrics makes it possible to receive the stock of pellet, it is assembled on a dynamometric hook in order to calculate consumption.
