PRH is a constant pressure controller primarily used for controlling fans by means of an analogue 0-10 V signal. It is typically used in domestic air extraction systems for bathrooms and cooker hoods.
The PRH controller could be installed in a stair well or similar location while the accompanying PTH pressure transducer is usually installed near by the most remote cooker hood.
With PRH, installation costs are low as the constant pressure controller is factory set for standard use. All that is required for the system to function when connected to mains voltage is that the pressure transducer and the fan control be connected to the constant pressure controller.
The PRH controller is supplied complete with PTH pressure transducer, air tube and tube connector, all in the one package.
