Product Advantages

This unit integrates high efficiency, stable operation, and intelligent control, offering the following core benefits:


1. Highly Efficient and Stable Compression Core
Equipped with a semi-hermetic twin-screw compressor, it delivers high operational efficiency, minimal vibration, and low noise levels, ensuring long-term, smooth, and reliable performance.

2. Durable and Reliable Mechanical Components
Key bearings are designed for a service life of at least 40,000 hours, providing a solid foundation for continuous and efficient operation.

3. Compact and Efficient Oil Separation System
Features a built-in high-efficiency oil separator with a compact design and exceptional separation performance, effectively ensuring oil return and system stability.

4. Precise and Flexible Capacity Control
Capable of multi-stage or stepless capacity regulation from 0% to 100%, it accurately matches cooling load demands, significantly reducing energy consumption.

5. Superior Heat Exchange Performance
Comes standard with a high-efficiency shell-and-tube evaporator (stainless steel plate heat exchanger optional). The enhanced internal finned tubes are optimally designed for excellent heat transfer.

6. Comprehensive Intelligent Control Functions
The control system integrates multiple programs for startup, capacity adjustment, shutdown, fault diagnosis and protection, operation statistics, and status display, offering a high level of automation and ease of management.

7. User-Friendly Human-Machine Interface
Fitted with an LCD touch-screen controller that displays real-time operating status and parameters, ensuring straightforward and convenient monitoring and operation.

8. Simplified Installation and Cost Savings
Utilizing air-cooled condensing, it eliminates the need for a cooling tower and associated water pumps and piping. This saves installation space, reduces initial investment, and simplifies maintenance.
