Product Features

1. Efficient and energy-saving: high-efficiency falling film special screw compressor: adopting a new generation 5:6 screw tooth design, high-precision grinding processing, and high volumetric efficiency; Adopting an internationally efficient fluorine resistant motor, it operates efficiently under various operating conditions.
Evaporative condensing chiller high-efficiency falling film or dry evaporator: using falling film evaporation technology, the heat transfer efficiency is more than twice that of traditional dry evaporators, and the energy efficiency of the unit is 14% higher than that of traditional dry evaporator systems; Efficient evaporative condenser:
The condensation heat of refrigerant is directly discharged to outdoor air and water, without intermediate heat exchange links in the cooling water system. The condensation temperature of the unit can be reduced by about 4 ℃ compared to traditional water-cooled units, and the energy efficiency ratio can be improved by 12%. At the same time, it can also save the need for cooling water pumps and has low power consumption.
The cooling water spray system adopts a large flow anti clogging basket type nozzle to ensure continuous and uniform water distribution, allowing water, air, and refrigerant to fully exchange heat and ensuring excellent heat transfer performance of the condenser; Using the technology of Feng Shui co directional mixed flow heat exchange coil and PVC packing combination to achieve efficient heat exchange; Stepless energy control of evaporative condensing chiller: Real time monitoring of refrigeration load based on changes in chilled water temperature, stepless adjustment of compressor capacity to adapt to real-time load changes, high partial load efficiency, and water temperature fluctuation range of only ± 0.5 ℃;

2. Quality: High reliability Compressor: With few operating components, fluorine resistant motor, built-in PTC protection module, and Swedish SKF rolling bearings for the main bearings, the service life can reach up to 100000 hours. So far, hundreds of thousands of compressors have been operated around the world;
Strict airtightness and vacuum testing to ensure that there are no leakage points in the entire machine and components; Rigorous tests for corrosion resistance, durability, and performance ensure that any evaporative condensing screw chiller unit is a highly reliable product.
The shell of the evaporative condenser is made of imported aluminum zinc plate, which is one of the most corrosion-resistant plates today. Its service life is 3-6 times that of ordinary galvanized plate, and it has the advantages of strong thermal resistance, high heat resistance, and beautiful appearance. The condensing coil is made of high-quality seamless fluid tubes bent, and the coil is hot-dip galvanized as a whole after welding to enhance its anti-corrosion ability;

3. Integrated evaporative condensation screw industrial chiller high-efficiency secondary oil separator: Reliable oil treatment system: high-efficiency oil separation designed inside the compressor, high-efficiency secondary oil separation combined with external mechanical and adsorption, unique evaporator concentration injection return oil, etc., improve heat transfer efficiency while ensuring the reliability of the unit. Low temperature refrigeration and pressure stabilization technology. During low-temperature cooling in winter, by automatically adjusting the opening of the compressor exhaust pressure regulator valve, the exhaust pressure can be stabilized at the required limit value, which not only improves the operating efficiency of the unit but also ensures the required oil supply pressure difference.
Through technological innovation in the fluorine circuit system of integrated evaporative condensation screw industrial chillers, the reliability problem of winter refrigeration is effectively solved, and customers do not need to adjust the cooling water temperature and flow rate.
4. Quiet operation: The semi enclosed structure screw compressor adopts a double-layer shell, and the base is equipped with vibration damping pads for smooth and reliable operation with low noise; The ventilation system adopts a specialized aluminum alloy axial fan for heat dissipation, with a forward leaning blade structure design and a streamlined inlet duct. It has low wind resistance, large air volume, low noise, excellent performance, and high efficiency.
5. Intelligent control of evaporative condensing chiller unit
Siemens PLC microcomputer controller;
● Humanized operation interface, users only need to perform power on/off, mode selection, and water temperature setting
The unit operation can be completed;
● Stepless or multi-stage energy regulation, water temperature control accuracy up to ± 0.5 ℃, precise temperature control requirements;
● Remote monitoring system (optional)
☆ Can achieve group control of up to 8 units and centralized control of chilled water pumps;
☆ Automatically determine load and optimize system operation efficiency;
☆ Automatically record and save operating parameters such as water temperature, refrigerant pressure, and current, and transmit them in real-time to the port. The manufacturer provides expert level technical services at any time;
Automatically send SMS to client device management personnel and manufacturers in case of malfunction.

In short, the integrated evaporative condensation screw industrial chiller is known for its high efficiency, energy saving and environmental protection, and has been recommended and used by a large number of customers since its launch. The unit adopts high-efficiency heat exchangers and a special external structural design and system. It can be directly installed on the roof or other well ventilated outdoor areas without the need for a separate computer room, saving building space. Exquisite and aesthetically pleasing in appearance, the unit can adopt an integrated design according to the actual situation, with high space utilization and small external dimensions to adapt to harsh outdoor weather conditions, ensuring that the integrated evaporative condensing screw industrial chiller has a good operational effect throughout its service life.
