Dual mechanic pressure switch for low and high pressures (LP / HP)
Ranco O17H4701 (O17-H4701) protects systems from extremely low suction pressures and extremely high discharge (discharge) pressures.
It is a dual type mechanical pressure controller equipped with a unipolar SPDT switch.
Especially useful for refrigeration and air conditioning systems where it is very important to turn on and off the refrigeration compressors, adjust the start and stop of air-cooled condenser fans and adjust other components that require the pressure control function.
LP range (low pressure): - 0.3 ~ 7 bar (PSI: 10 ~ 100); HP range (high pressure): 7 ~ 30 bar (PSI: 100 ~ 435)
Adjustable car pre-control for both LP and HP.
Connections: 7/16 - 20 UNF straight output male type connection.
Stable accuracy and repeatability.
Equipped with pressure switch support; standard bellows.
Storage temperature range: -40 ° C / + 65 ° C; ambient working temperature: -30 ° C / + 55 ° C.
Application for equipment with common HCFC refrigerants, non-flammable HFCs and new generation HFO refrigerants: R134a, R404A / R507, R407C, R22, R407A / F, R448A / 449A, R452A, R513A, R450A ...
