Installation
The DN32 anti-condensation pump unit, thanks to the generous dimensions of the thermic valve, can feed directly the distribution unit (hydraulic separator and zone manifold) without having to pass through the buffer tank. In fact the very low headlosses of the pump unit guarantee a hight flow rate in the primary circuit up to 4000 l/h.
