Tailored for CO2 refrigerant systems with higher pressure requirements, this controller delivers reliable high-pressure protection. It integrates advanced design and robust materials to meet the demanding needs of industrial refrigeration and high-pressure equipment.

Adopts British pipe thread quick connectors or copper tube welding for tool-free, flexible installation. Offers plug-in or wire connection options to fit diverse setups. The sealed stainless steel pressure sensor and steel explosion-proof housing ensure safety in harsh environments. Factory-calibrated pressure parameters eliminate on-site setup, enabling immediate use.

Built with a reversible stainless steel diaphragm that flips when sensing preset pressure, driving electrical contacts to open via a guide rod. Automatically resets when pressure drops below the recovery value, ensuring continuous system protection without manual intervention.

Ideal for CO2-based refrigeration equipment (e.g., commercial refrigerators, industrial freezers) where system pressure exceeds conventional refrigerants, providing critical high-pressure protection.

Suitable for various tools and machinery requiring high-pressure protection above 800PSI (5.5MPa), including hydraulic systems, pressure vessels, and industrial process pipelines operating in -30℃～+80℃ ambient conditions.
