The Open-type Two-stage Screw Compressor Unit is classified into a total of 7 models. Through two-stage compression, compression occurs consecutively twice, which is suitable for operating conditions with high compression ratios. The unit is used in conjunction with a variable frequency motor to enhance operational efficiency during load variations. It is applicable to R717, R404A, R507, and similar refrigerants. Standard equipment includes a compressor, open-type motor, control center, oil separator, intermediate cooler, oil cooler, high-capacity filter, pre-lubrication oil pump, automation components, and more.
Key Features and Benefits
• High-efficiency screw compressor ensures a higher COP value.
• Utilizing an open asynchronous motor, renowned for its high efficiency and low noise, while also offering the option of a permanent magnet synchronous variable frequency motor.
• Employing a differential-pressure oil supply system with a small oil pump for pre-lubrication ensures both energy savings and reliability.
• Installation of an economizer enables subcooling of high-pressure liquid from the condenser, thereby enhancing the system's COP.
• Featuring fully automatic one-key start-up, real-time analysis, and monitoring of operational status, as well as remote control and historical data storage.
• Automatic capacity control ensures the unit operates efficiently under various working conditions.
• Equipped with a comprehensive preventive safety and protection system, ensuring safety and reliability even during unmanned operation.
• All components sourced from reputable manufacturers, ensuring high reliability and guaranteed quality.
• Each unit undergoes rigorous testing and performance checks to ensure overall quality.
