Description
The circulation unit mod. D2025 and D2050S is used to distribute the delivery fluid of the heating system at the same temperature as the primary circuit (boiler, heat pump, district heating, ...).
The installation is foreseen on the main manifold with a delivery / return center distance equal to 90mm.
It is composed by:
- Insulating shell made off closed-cell, cross-linked expanded polypropylene;
- Plant side : 1 "F-F two-way shut-off valves for connection to the system delivery / return, with integrated thermometers in the knobs;
- Non-return valve;
- High efficiency circulator (also available model without circulator);
- Collector side: connections with flat flange and Ø 1 "F swivel nut.
