Open water-cooled chiller unit Water cooled chiller

Product features of billions of mechanical open chillers

Condenser

Made with the latest high-efficiency external threaded copper tube from Kobe, Japan, it has a large heat dissipation capacity and a compact size. Using the latest CAD/CAM design and processing technology, combined with CNC machining center production, the structure is compact and highly reliable. Beautiful appearance, efficient and energy-saving microprocessor control system, industrial grade PLC unit centralized control, combined with the adjustable system of the compressor, can timely and accurately control the matching of the unit's cooling capacity and cooling load, ensuring the unit operates at the best efficiency and reducing operating costs. Internally integrated with multiple safety protection and treatment functions such as water cut-off, low temperature, high and low pressure, antifreeze, phase loss, delayed start, reverse phase, overload, motor overheating, oil pressure difference, etc. Full Chinese operation interface, menu style prompts, allowing for arbitrary setting of unit operation status, and a home appliance based operating environment.

New high-efficiency evaporator
The latest high-efficiency internally threaded copper tube from Kobe, Japan, enhances heat transfer efficiency and is more energy-efficient. Using the latest CAD/CAM design and processing technology, the CNC machining center is completed with a compact structure, small size, and durability. The U-shaped heat exchange tube bundle can be removed as a whole to clean the internal scale, which is convenient for maintenance and repair. Dry evaporator, convenient for oil return, improves compressor life and system reliability.

World renowned compressor brand

We use semi enclosed screw compressors from Italy's Lefcon, Japan's Shengang, Taiwan's Fusheng, and Hanzhong, as well as original imported twin-screw series compressors. Twin screw 5:6 gear ratio and advanced linear design, energy-saving and efficient. Efficient active valve energy control, achieving graded or stepless energy control. Balanced design ensures ultra quiet and smooth operation. Strict handling of moving parts, special oil balance block design for exhaust, long maintenance cycle, and over 40000 hours of fault free operation. Efficient oil separator, with an exhaust oil output of less than 1.5%, effectively improves heat exchange between the two exchangers, making it more energy-efficient and durable.

Easy to install

1) Safe and balanced operation, minimal vibration, and simple installation;
2) The unit has a compact structure, small footprint, light weight, and is easy to transport;
3) The control interface directly displays the fault content, which facilitates timely understanding and troubleshooting of the fault
4) Before leaving the factory, various performance tests are completed, refrigerant and lubricating oil are filled, and wiring is completed. Customers only need to connect the inlet and outlet pipes and power supply to operate, reducing installation time and costs.
Reliable operation

1) The unit is equipped with multiple safety protection measures to ensure its normal operation.

2) The unit is equipped with single and double circuit designs to meet customers' different choices. When a single compressor of a dual circuit configuration unit malfunctions, the other compressor can still operate normally without affecting customer use.
3) The motor adopts the world's most advanced Japanese PTC thermal protection, which provides more sensitive and reliable protection
4) All units undergo 100% testing through a safety inspection system before leaving the factory to ensure that their performance meets the standards.
