FSD-W MICRO DIFFERENTIAL PRESSURE CONTROLS

FSD-W series micro differential pressure controls (Hereinafter referred to as the controller) are widely used in air cooling or water cooling units, such as plate heat exchanger, double-pipe heat interchanger, Shell and tube heat exchanger, etc. The controller monitor the states of the water flow and the water pump and filter in order to ensure the heat exchanger under regular work. The controller is a kind of automatic controller.

It's working principle: Installed on the water inlet and outlet of the heat exchanger to sensor the differential pressure of the water inlet and outlet. When heat exchanger with impurity, jams, (the phenomenon such as ice), causing the inlet and outlet pressure difference increases, when the pressure difference is larger than the set value, the controller disconnect circuit, so as to protect the heat exchanger.

Controller can be installed in any heat exchanger pipe diameter, the tube diameter size did not demand, and is not affected by flow interference characteristics.
