Daikin-McQuay 107225101 Pressure Switch
The Daikin-McQuay 107225101 Pressure Switch is a critical safety component designed for precise refrigerant monitoring in commercial HVAC systems. This SPST low pressure switch features a 22 PSI cut-in and 7 PSI cut-out (22/7#) setpoint, engineered to protect the compressor from low suction pressure conditions that could lead to motor burnout or oil migration issues. Built to meet OEM specifications for McQuay chillers and Daikin rooftop units, this auto-reset pressure control ensures reliable operation by breaking the electrical circuit when system pressure falls below the safety threshold and re-engaging once pressure stabilizes within the 15 PSI differential.
Constructed for high-duty cycle environments, the 107225101 refrigerant pressure switch utilizes a durable encapsulated design to resist vibration and moisture ingress. For technicians performing HVAC compressor troubleshooting, this component provides a direct fit replacement for legacy McQuay part numbers, maintaining the integrity of the original control logic. Whether you are servicing a water-cooled chiller or an air-handling unit, this low-side pressure sensor is essential for preventing thermodynamic instability and ensuring the longevity of the refrigeration circuit.
Key Benefits- Precise 22/7# Calibration: Factory-set for accurate low-limit protection in R-22 or R-410A systems.
- Encapsulated SPST Contacts: Provides reliable switching performance and enhanced resistance to environmental contaminants.
- Direct OEM Replacement: Ensures full compatibility with Daikin-McQuay control systems without field modifications.
- Automatic Reset Logic: Minimizes system downtime by restoring operation once the low-pressure condition is cleared.
- Robust Connectivity: Designed for standard lead-wire or terminal configurations common in industrial HVACR applications.
What is the cut-in/cut-out differential for this switch?
The Daikin-McQuay 107225101 operates with a fixed 15 PSI differential, cutting out at 7 PSI and resetting (cutting in) at 22 PSI.
Can this switch be used on high-pressure R-410A systems?
Yes, this HVAC low pressure cutout is rated for the operating pressures of standard refrigerant blends, provided the safety setpoints align with the equipment's recovery requirements.
Is this an automatic or manual reset switch?
This is an auto-reset pressure switch, meaning the electrical path closes automatically once the refrigerant pressure rises back above the 22 PSI cut-in point.
