ModuSat® Single Plate Double Circuit

The unit consists of a single plate heat exchanger, combined with electronic PID control using Pressure Independent Control Valve (PICV) with modulating actuator achieving a low primary return temperature as well as providing differential pressure control and flow rate regulation.

The SP-DC heat interface unit uses a diverter valve to switch secondary flow either through the heating circuit or fed to the external DHW tank and operates in DHW priority mode to provide fast recovery of hot water. In addition to this the ModuSat® can provide direct control of underfloor heating output temperature without the need for any underfloor pumps, blending valves or mixing valves.

Available in a range of plate sizes and connection configurations, the unit is suitable for many different type of installation.

The heating circuit consists of a plate heat exchanger (PHE), safety relief valve, pressure gauge, 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® two-way communication. Suitable for radiators, underfloor heating or fan coil units.
