REFRIGERATION PRESSURE SWITCHES (LOW & HIGH PRESSURE)

Description

The Refrigeration Pressure Switches (Low & High Pressure) are essential safety and operational controls engineered to continuously monitor system operating pressures and guard compressors against critical equipment failure. Manufactured with robust, corrosion-resistant housings and metal alloy pressure connections, these switches automatically interrupt power or cycle fans when suction or discharge pressures pass safe operating limits. Featuring calibrated adjustment scales and responsive internal bellows, this switch series is ideal for air conditioning units, chillers, and commercial refrigeration systems—preventing overpressure damage, loss-of-charge freeze-ups, and excessive equipment strain.

Technical Specifications

Key Features

• Accurate Pressure Regulation: Maintains system pressure within tight, calibrated limits to protect sensitive cooling circuits.

• Automatic Control Action: Automatically trips electrical contacts on/off at preset cut-in and cut-out thresholds.

• Snap-Action SPDT Switching: High-current SPDT microswitch provides clean contact breaks to prevent electrical arcing and chattering.

• Durable Industrial Design: Built with corrosion-resistant metal alloy pressure ports and sealed bellows for continuous operation.

• Compact & Easy Installation: Modular footprint with universal mounting brackets allows fast panel or inline setup.

Supported Applications

Important Buyer Verification Notes

Notice for Technicians & Contractors: Confirm whether your control circuit requires Automatic Reset or Manual Reset before installation. Perform a bubble leak test at the 1/4″ pressure connection port and ensure power is isolated prior to adjusting differential or range setpoint screws.
