Dual automatic pressure control Ranco O17 H4 701

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 ...
