Cartridge pressure switches type ASV (Saginomiya)
Pressure switches must protect the refrigeration plant from too high discharge pressure and low compressor suction pressure. Increasing the discharge pressure above a certain value can lead to an accident: destruction of the refrigeration unit, jamming of the compressor, burning of electrical windings. Significant reductions in suction pressure impair oil return to the compressor and may also freeze water or ethylene glycol in chillers.
