Shenzhen Hanxinde Brand High-Quality Industrial Water-Cooled Screw Chiller for Low-Temperature Cold Water

The liquid refrigerant in the evaporator absorbs heat from the water and begins to evaporate. Once completely evaporated into a gas, it is compressed by the compressor. The gaseous refrigerant absorbs heat through the condenser and condenses into a liquid. After throttling through a thermal expansion valve (or capillary tube), it becomes a low-temperature, low-pressure refrigerant and enters the evaporator, completing the refrigerant cycle. The circulating medium (tap water or antifreeze) temperature will drop slightly. This repetitive cycle continuously yields the desired refrigeration effect.

Calculation of chilled water consumption for water-cooled cooling systems: For water-cooled systems that use cooling water to cool cylinders, the consumption of cooling water should be determined based on the manufacturer's provided data.

Product Description - Common Materials

Refrigeration Compressors: Featuring semi-hermetic screw compressors from Japanese Panasonic, American Copeland, Danish Danfoss, German Bitzer, Taiwan Hanbell, and Fusheng, etc., these compressors are known for their high efficiency, durability, and low noise levels.

Evaporator: The evaporator features a shell-and-tube heat exchanger with internally threaded copper tubes, offering a smooth outer surface and excellent evaporation performance. It prevents water quality degradation from affecting the refrigeration performance. The evaporator cylinder is insulated with 25mm thick PE insulation board, preventing condensation and minimizing heat loss.

Condenser: The condenser employs a shell-and-tube design, utilizing high-efficiency brass tubes imported from abroad. These tubes are machined into external threaded trapezoidal finned tubes to enhance heat transfer efficiency. The interior of the copper tubes is smooth, reducing water pressure and making them easy to clean and maintain.

Imported Brand Refrigeration & Freezing Parts: All freezing parts are selected from world-renowned brands like ALCO (USA Eco) and DANFOSS (Denmark Danfoss), offering excellent performance, safety, and environmental protection.

Intelligent Computer Control System: Our company has developed a high-intelligent PLC and PC-level computer control system. The electrical controls use the imported German Schneider brand. The main unit is connected to the power supply, offering optional remote control. It features automatic loading and unloading, scheduled on/off, and fault cause recording. The system is user-friendly, has a low failure rate, high safety factor, easy installation, and allows for immediate adjustments in system control, ensuring a straightforward and reliable operation.

The protection system is equipped with: compressor delay start protector, overload protector, high and low pressure protector, flow switch, frost protection, fuse plug, compressor overheating protector, frequent start protector, and abnormal indicator light, ensuring the normal operation of the unit.

The high-quality industrial chiller units from Shenzhen Hanxinde feature high and low-pressure gauges above the front panel. These gauges allow for clear visibility of the high and low-pressure values. Should the pressure values fall outside the specified range, the unit will provide corresponding fault alerts.
