Refrigeration Guard accessory Samsung Guard Ref Low — protective module, model Guard Ref Low

Samsung Guard Ref Low is a protective module designed for refrigeration systems to provide low-pressure and low-temperature protection for compatible Samsung refrigeration units. Intended for use in commercial and industrial refrigeration setups, the module monitors conditions in the cooling circuit and helps prevent compressor damage or system faults arising from abnormally low suction pressure or excessively low evaporator temperatures.

Advantages

The Guard Ref Low module offers continuous monitoring of low-pressure and low-temperature conditions, enabling automated interruption or protection actions when preset limits are reached. Its design supports straightforward integration with compatible Samsung refrigeration control systems and compressors, reducing the need for complex custom wiring. By detecting potentially harmful operating states early, the module helps maintain system reliability and can reduce unplanned downtime and repair needs.

Suitable for

• Commercial refrigeration cabinets and display cases
• Cold rooms and walk-in freezers in retail or food service environments
• Industrial refrigeration systems requiring low-pressure/low-temperature protection
• Compressor-driven cooling circuits where automated safeguard functions are needed

Key specifications

• Function: low-pressure and low-temperature protection for refrigeration systems
• Compatibility: designed for integration with compatible Samsung refrigeration control systems and compressors
• Application environment: commercial and industrial refrigeration installations
• Monitoring capability: continuous detection of suction pressure and evaporator temperature deviations

How to use

Install the Guard Ref Low accessory according to the refrigeration system manufacturer’s wiring and mounting instructions, ensuring correct connection to the refrigeration control unit and compressor protection circuits. Configure protection thresholds and reset behavior via the compatible Samsung control interface or according to system documentation. After installation, verify operation by performing system checks under normal and simulated low-pressure/low-temperature conditions, and confirm that protective actions such as compressor lockout or alarm signaling occur as intended.

Usage recommendations

Use the module only with refrigeration equipment and control systems that list compatibility with Samsung Guard Ref Low. Verify sensor inputs and electrical connections before commissioning, and follow routine maintenance schedules for refrigerant charge, filter/drier condition, and sensor calibration to ensure reliable protection performance.
