ModuSat XR & XR-ECO Heat Interface Units

The complete solution for instantaneous hot water and indirect space heating in communal heating systems.

Heat interface units for indirect heating and instantaneous domestic hot water (DHW) with electronic PID control using Pressure Independent Control Valves (PICVs) with modulating actuators achieving a low primary return temperature as well as providing differential pressure control and flow rate regulation.

Heating

The heating circuit consists of a plate heat exchanger (PHE), PICV, safety relief valve, manometer, flow and return temperature sensors, Wilo PWM circulation pump and expansion vessel. The heating circuit flow temperature is controlled by the modulation of the primary flow rate with the integrated PICV actuator. Weather compensation is applied to the set heating temperature using SmartTalk 2-way communication. Suitable for radiators, Underfloor Heating or fan coil units.

Domestic Hot Water

Domestic hot water is heated via a separate plate heat exchanger and the temperature is regulated by the modulation of primary flow rate with the integrated PICV actuator. When fitted, the Lime scale reducer minimises lime scale formation.

ModuSat XR-ECO

Designed for modern low temperature heat networks, ModuSat XR-ECO units provide excellent heating and hot water performance at heat network primary flow temperatures as low as 60 C or even 55 C.
