Product Features

1Efficient and energy-saving: high-efficiency falling film special screw compressor: using the latest generation5：6Screw tooth design, high-precision grinding and processing, high volumetric efficiency; Adopting internationally renowned brand high-efficiency fluorine resistant motors, they operate at optimal efficiency under various operating conditions.

Evaporative condensing chiller high-efficiency falling film or dry evaporator: using falling film evaporation technology, the heat transfer efficiency is improved compared to traditional dry evaporators2More than twice, the energy efficiency of the unit is improved compared to traditional dry evaporator systems14%Efficient evaporative condenser:

☆ The condensation heat of refrigerant is directly discharged to outdoor air and water, without any intermediate heat exchange link in the cooling water system. The condensation temperature of the unit can be reduced compared to traditional water-cooled units4Around ℃, the energy efficiency ratio can be improved12%At the same time, it can also save on 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, enabling sufficient heat exchange between water, air, and refrigerant, and ensuring excellent heat transfer performance of the condenser; Using Feng Shui mixed flow heat exchange coils,PVCThe technology of packing combination achieves efficient heat transfer; 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 efficiency at partial loads, and water temperature fluctuation range of only ±0.5℃；

2Excellent Quality: High Reliability Compressor: Fewer Running Components, Fluorine Resistant Motor, Built inPTCProtection module, main bearing using SwedenSKFRolling bearings with a lifespan of up to10Ten thousand hours, so far hundreds of thousands of compressors have been running 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 plated sheet, which is one of the most corrosion-resistant sheets available today. Its service life is longer than that of ordinary galvanized sheet3~6It 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;

3Integrated evaporative condensation screw industrial chiller high-efficiency secondary oil separator: Reliable oil treatment system: The compressor is equipped with a patented design for high-efficiency oil separation, an external mechanical and adsorption combined high-efficiency secondary oil separation, and a unique evaporator for concentrated injection and return oil, which improves heat transfer efficiency and ensures the reliability of the unit through 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 minimum 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.

4Quiet 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.
