N/A

NRF-VS Pump Control is a versatile variable speed control for use in hydronic heating and cooling applications.

Designed for use in hydronic heating and cooling applications. The temperature of the water is controlled by regulating the speed of the pump which injects water from a different temperature water loop (Primary loop) into a controlled loop (Secondary loop).

As the speed of the pump increases, more water is sent into the Secondary loop, resulting in a secondary loop water temperature change.

The NRF-VS Control is available either installed on a B&G NRF-22 or as a field mountable controller that can be installed onto a B&G wet rotor in the field. The snap-on design allows the NRF-VS to be quickly attached to a standard B&G wet rotor circulator.
