Dual head water-cooled screw chiller Water cooled screw chiller

The billion dollar water-cooled screw chiller adopts internationally renowned brand compressors, including semi closed screw compressors from Italy's Lefcon/Japan's Shengang/Taiwan Fusheng/Hanzhong, as well as 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.

New high-efficiency evaporator
Kobe, Japan's high-efficiency internally threaded copper tube enhances heat transfer efficiency and is more energy-efficient. Using CAD/CAM design and processing technology, CNC machining centers are used to complete the production, 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.
Condenser
The latest high-efficiency external threaded copper tube production in Kobe, Japan, with large heat dissipation and 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.
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.
Special design
1) The unit can flexibly design the external dimensions according to the conditions of the computer room, and can be shipped in pieces and assembled on site.
2) Multiple refrigerant options are available, and the unit can provide refrigerant media such as R22, R407C, R134a, etc.
3) We can produce units with different power supply standards according to the power supply of different countries and regions. We can also customize screw chiller units and various high-voltage non-standard units such as anti-corrosion and saltwater units according to user requirements.
