The Low Pressure Freeze Control combines a pressure sensing mechanism with a time delay. A drop in pressure
energizes the time delay relay which opens a contact after a predetermined time period.


  • Heavy-duty low profile pressure elements withstand
    excessively high overrun pressure that may be
    encountered in system testing.
  • Time delay relay incorporates trip-free manual reset.
  • The timing mechanism (time delay relay and terminal
    board) may be easily removed and replaced in the field.
  •  Ambient compensation minimizes the effect of
    temperature variations at the control location.
  •  Simple, single pointer scale indicates cutout pressure.
  •  Enclosed pressure actuated contacts.
  •  Single unit mounting and wiring saves installation time
    and material
