FSD series cooling tower differential pressure control is a kind of safety switch,

Which protects refrigeration compressor from damage of too low

oil pressure of lubricating oil. If the oil pressure is too low, the

controller will stop the compressor after a while.

FSD series differential pressure control can be used to make the

pipes reach a constant flow rate through controlling differential

pressure between inlet and outlet pipes in the water system.

FSD-C and FSD-T series all have adjustable differential pressure,

but FSD-T series incorporate a thermal time relay.
