Biomass Circulation Groups

ISPESL document dated 18/09/2006 regarding thermal plants with two heat generators, one of which feed through solid fuel and the other with a different fuel says that:
“In case the primary thermal fluid of two generators goes directly into the thermal tank, the sum of powers has to be considered; hence in case power is above 35 kW, the plant must be included in the M.D. 1/12/1975 and following norm updates. If instead there is a heat exchanger between the two generators, it can be considered as an hydraulic interruption between the two thermal fluids and therefore there is no need to sum the powers.”

The hydraulic units NOVABOX mod.111, thanks to their hydraulic layouts, comply with ISPESL document in addition to managing the heating circuit and have high level performances. The pumps, GRUNDFOS model UPM3 Hybrid, are high efficiency. There is the possibility to have up to 7 meter head pumps and the curves can be set with:

• Proportional pressure (default)

• Constant pressure

• Constant curves

A simple and complete installation is enabled thanks to hydraulic accessories which are supplied as standard:

• Valves

• Check valves

• Air vents

• Safety valves

• Temperature sensor

The hydraulic units can be supplied in metal boxes, to be wall-hung or to be built-in, painted.
