The open type air-cooled semi-hermetic piston condensing unit is suitable for chiller rooms, freezer rooms, food processing cold rooms, seafood cold storage, meat cold storage, and cold chain warehousing projects. The unit adopts a combined design of a semi-hermetic piston compressor and an air-cooled condenser. Heat is dissipated through high-efficiency axial fans, eliminating the need for a cooling tower or cooling water system. It offers flexible installation and is especially suitable for small and medium-sized cold rooms and commercial refrigeration projects.

The unit features an open structure with a clear layout of major components, making on-site installation, inspection, maintenance, and future servicing more convenient. According to different temperature ranges, cooling capacity requirements, and project conditions, the system can be equipped with refrigeration components such as liquid receivers, oil separators, suction accumulators, filter driers, solenoid valves, pressure gauges, and pressure controllers to meet the operating requirements of various cold room projects.

Compared with box type condensing units, the open type structure provides better heat dissipation space and easier maintenance access. Compared with water-cooled units, the air-cooled design reduces the need for a water system, lowering installation costs and maintenance complexity. It is ideal for projects without cooling water conditions or for customers who want a simpler refrigeration system configuration.
