Parker Thermalswitch for Air Oil Coolers

Sensing your Oil Temperature, Cycle Cooling Fans or Indicate Status.

Parker Temperature switches measure the oil temperature in ULAC, ULDC, and ULHC Series air oil coolers. When a fixed setpoint is reached, an onboard contact closes which may be used to cycle cooling fans or indicate status. Temperature switches improve working conditions of a hydraulic system by regulating the fluid temperature and maintaining ideal working conditions, thus saving energy and extending component life.

To ensure precise temperature control and working conditions of a hydraulic system, Parker temperature switches should be installed to control the motor (AC or DC) on air oil coolers.

The switches can also be used to alarm excessive fluid temperature.
