Product Description

Semi-hermetic two-stage screw units are categorized into six models.
These units utilize semi-hermetic two-stage screw compressors, which are leak-proof and widely applicable.
They are compatible with various natural refrigerants such as R717, R22, and R507. Combined with variable frequency motors, they enhance operational efficiency under varying load conditions.
The standard model consists of a semi-hermetic screw compressor, control center, oil separator, intermediate cooler, oil cooler, high-capacity filter, and automation components.

Key Features and Benefits

• The motor and compressor are integrated, allowing installation in compact spaces and facilitating easy transport.
• Equipped with a permanent magnet synchronous motor and customized special materials, it is compatible with various refrigerants such as R22, R404A, R507, and R410A.
• An intermediate cooler enhances the system's COP by subcooling high-pressure refrigerant in the condenser.
• The unit can be started with the push of a single button, with real-time monitoring and analysis of operating conditions. It also supports remote control and stores historical data for recordkeeping.
• The intelligent control system features multiple preventative protection modules and fault warning capabilities.
• Both the high-capacity precision oil filter and the suction filter are detachable, making cleaning and maintenance convenient.
• A four-stage oil separation system achieves a separation rate of up to 99.9%, and a high-efficiency oil cooler is installed, offering a choice between water-cooling and refrigerant cooling.
• All components are sourced from trusted, high-quality, well-known brands.
• The overall performance of the unit is tested and inspected to ensure quality assurance.
