Description

Two heat sources, one cylinder.

The Mastersol BL2 is a vertical hot water cylinder with two permanent heat exchangers: coils of 1″ steel pipe, enamelled. It is triple energy: the two heat exchangers connect to two heat sources, for example a boiler and solar collectors, and it also takes a 4 kW electric heating element, on request.

Inside, it is protected from corrosion by Direct Glass liquid enamel, fired at 850 °C, 400 microns thick, made of inorganic silicates without chemical additives (DIN 4753 Teil 3 & 6). The glass bonds fully to the steel and follows its expansion and contraction. It is built to DIN 4753 and EN 12897.

It stands upright and has ports for recirculation and for an immersion thermometer, a cleaning flange and a magnesium anode. The insulation is 55 mm polyurethane, 52 kg/m³, injected by an automatic machine; on the 750 and 1,000 litre models it is removable soft polyurethane, 100 mm. The outer jacket is soft PVC, in a colour of your choice. It is meant for homes and businesses, from 150 to 1,000 litres.
