SWITCH PRESSURE (MRD-12-00628-31) HP2

The Pressure Switch is an essential safety and control device in transport refrigeration systems. It monitors refrigerant pressure within the system and helps protect components from operating outside safe pressure ranges.

• Pressure Monitoring: The pressure switch detects pressure levels in specific parts of the refrigeration circuit, such as high or low-pressure sides.
• System Protection: If pressures exceed or drop below preset limits, the switch activates to shut down the compressor or trigger alarms, preventing damage.
• Maintaining System Efficiency: By controlling compressor operation based on pressure feedback, the switch helps maintain optimal refrigeration performance.
• Automatic or Manual Reset: Depending on design, some pressure switches reset automatically once normal pressure is restored, while others require manual intervention.
• Diagnostic Utility: Activation of the pressure switch can indicate issues such as refrigerant leaks, blockages, or component malfunctions, aiding maintenance.

In summary, the pressure switch plays a critical role in safeguarding transport refrigeration systems by monitoring pressures and preventing unsafe operating conditions.
