Product Features

1. High Efficiency and Energy Saving: Special Screw Compressor with High Efficiency Film Evaporation: Equipped with the latest 5:6 screw tooth design and high-precision grinding, boasts high volumetric efficiency; utilizes a high-efficiency fluorine-resistant motor from an international renowned brand, ensuring optimal efficiency under various operating conditions.

High-efficiency film-type or dry evaporative condensing cooling water units: Utilizing film evaporation technology, the heat exchange efficiency of the unit is over twice that of traditional dry evaporative condensers, and the energy efficiency ratio of the unit is improved by 14% compared to the traditional dry evaporative condenser system; High-efficiency evaporative condenser:

The refrigerant's condensation heat is directly released to the outdoor air and water, eliminating the intermediate heat exchange process of a cooling water system. The condensation temperature of the unit can be reduced by about 4℃ compared to traditional water-cooled units, improving the energy efficiency ratio by 12%, and also eliminates the need for a cooling pump, resulting in low power consumption.

The cooling water spray system features large flow rate, anti-clogging basket-style nozzles to ensure continuous and uniform water distribution, allowing for optimal heat exchange between water, air, and refrigerant, guaranteeing the condenser's excellent heat exchange performance. It employs a co-current mixed flow heat exchange coil with PVC packing technology for high-efficiency heat exchange. The evaporative condenser chiller has a stepless energy control: it monitors the refrigeration load in real-time based on the freezing water temperature change and can infinitely adjust the compressor capacity to accommodate real-time load variations, with high part-load efficiency and a water temperature fluctuation range of only ±0.5°C.

2. Exceptional Quality: High Reliability Compressor: Few moving parts, fluorine-resistant motor, built-in PTC protection module, main shaft with Swedish SKF roller bearings, lifespan up to 100,000 hours; tens of thousands of compressors are operating worldwide to date.

Rigorous airtightness and vacuum tests ensure the entire unit and components have no leakage points; stringent corrosion resistance, durability, and performance tests guarantee that every evaporative condensing screw chiller is a high-reliability product.

The outer shell of the evaporative condenser is made of imported aluminum-zinc coated steel sheet, which is one of the most corrosion-resistant materials available today. It boasts a lifespan up to 3-6 times longer than standard galvanized steel sheets, featuring strong thermal resistance, high heat resistance, and an aesthetically pleasing appearance. The condenser coils are bent from high-quality seamless fluid tubes and are then heat-dipped galvanized after welding, enhancing their corrosion resistance.

3. Integrated evaporative condensing screw industrial chilled water unit with an efficient secondary oil separator: Reliable oil treatment system: Efficient oil separator with an internal design in the compressor, combined with external mechanical and adsorption for secondary oil separation, and unique evaporator concentration suction back oil, which enhance heat exchange efficiency while ensuring the unit's reliability and stable low-temperature refrigeration technology. During winter low-temperature refrigeration, by automatically adjusting the compressor exhaust port pressure regulating valve opening, the exhaust pressure is maintained at the required minimum limit, thus improving the unit's operating efficiency and ensuring the necessary oil pressure difference.

Through innovative technology in the refrigerant system of an integrated evaporative condensing screw industrial chiller, effectively resolves the reliability issue of refrigeration in winter, eliminating the need for customers to adjust cooling water temperature and flow.

4. Quiet Operation: Semi-enclosed screw compressor with double shell design, equipped with vibration-damping pads on the base, operates smoothly and reliably with low noise; the ventilation system uses special aluminum alloy axial flow fans for heat dissipation, featuring an advanced forward-inclined blade design and a streamlined inlet duct, offering low wind resistance, high airflow, low noise, excellent performance, and high efficiency.
