This series of chiller units incorporates advanced screw technology, integrating high efficiency, stability, and intelligence for medium to large-scale cooling applications. With exceptional engineering design and reliable core components, they deliver consistently efficient and stable performance under various operating conditions, making them an ideal solution for industrial process cooling and comfort air conditioning.


Product Advantages:

● High Efficiency & Quiet Operation: Utilizes semi-hermetic twin-screw compressors for superior efficiency, smooth operation, and significantly reduced noise levels.

● Extended Service Life: High-quality bearings are selected for a design life exceeding 40,000 hours, ensuring long-term reliability.

● Compact Design with Effective Oil Separation: Features a built-in high-efficiency oil separator with a compact structure for optimal oil separation and system stability.

● Precise Modulation & Energy Savings: A multi-stage capacity control system enables smooth and precise load adjustment from 0% to 100%, significantly reducing energy consumption by accurately matching cooling demand.

● Superior Heat Exchange & Flexibility: The evaporator employs a high-efficiency shell and tube heat exchanger with internally enhanced fin tubes for optimized design and outstanding performance. A stainless steel plate heat exchanger is available as an option to suit diverse application requirements.

● Comprehensive Intelligent Control: Equipped with full automatic control functions including startup self-check, intelligent capacity regulation, sequential shutdown, multiple fault protection and diagnosis, operation data logging, status monitoring, and auto-restart, ensuring safe and efficient unit operation.

● User-Friendly Interface: Features a color LCD touch-screen controller with an intuitive interface for easy monitoring of real-time operating status and straightforward operation.

● System Compatibility: Designed to be used with a cooling tower for seamless integration into your cooling system.
