High and low pressure switches are mechanical safety protection components for refrigeration condensing units. High pressure switch triggers alarm and stops unit when condensing pressure rises above safe upper limit. Low pressure switch protects compressor when suction pressure drops below preset lower threshold. Pressure sensing tube connects directly to refrigerant pipeline to capture real-time system pressure. Switch action value needs periodic calibration to keep protection parameter accurate over years. Formal refrigeration factory sets pressure protection parameters before condensing unit delivery. Xindacool fits adjustable high-low pressure switches for all industrial refrigeration condensing units. Aging pressure switch may lose sensitivity and fail to respond under abnormal pressure conditions. About 33% of refrigeration system safety failure accidents relate to uncalibrated pressure switches. Pressure switch should be isolated from strong vibration to prevent parameter drift and false action. After each pressure test or pipeline overhaul, operators need to verify switch protection function. High and low pressure switches form the first line of safety defense for refrigeration equipment.
