01 Semi-hermetic Compressors
▪ Adopted world famous branded semi-hermetic compressors for long term reliable and efficient running; ▪ Compressor runs with no stage limits to realize stageless continuous adjustment of cooling capacity in between 25%-100% power loaded and maintaining stable outputs; ▪ Option: HANBELL, BITZER
02 AIr cooled high-efficient inner threaded copper-tubing hydrophilic aluminum foil fin type Evaporator
The condenser type is hydrophilic aluminum foil fin type. The aluminum foil is hydrophilic treated. Through special processing, a hydrophilic layer is coated on the surface. The condensed water will spread quickly on the hydrophilic aluminum foil and will not condense into water droplets. Increase the heat exchange area, speed up the cooling and heating speed, and effectively avoid the noise caused by condensed water blocking the air flow.

The raw material of the heat exchanger is hydrophilic aluminum foil, which can increase the refrigeration efficiency by 5%. It is also anti-corrosion and anti-mold, has no odor, and will not cause the accumulation of water droplets to block the heat exchange.
shell and tube type evaporator adopts inner treaded copper design, with larger heat exchanging area for higher efficiency and maximizing system performance.
05
Adopt welded angle filter, the filter element is imported molecular sieve. Can filter water, acid and other impurities, and easy to replace. 
06 Thermal expansion valve
The imported thermal expansion valve is used to throttle and cool the high-pressure super cooled liquid into a low-temperature and low-pressure liquid, and automatically adjust the flow rate of the refrigerant into the evaporator according to the evaporation temperature, and maintain a certain pressure to ensure evaporation in the evaporator. rate.
07 Electrical control system
The control panel is an LCD touch screen, highly automated, easy to operate, intuitive interface, which can make the unit to continuously adjust the performance energy between 25% and 100% (or stepless energy adjustment) to ensure the complete performance of the compressor Play and help users save operating costs to the greatest extent. The control panel interface has two languages, Chinese and English.

08 Safety protection device:
The system is equipped with motor overload, short circuit protection, overheating, high pressure, low pressure, compressor delay start protection, water flow protection and other functions, the unit runs safely and reliably.
Product Features
High Efficiency and Energy Saving: Some units feature a free cooling function, utilizing outdoor air for free cooling when ambient temperatures are low, reducing compressor operating time. The high efficiency of screw compressors also helps reduce energy consumption.
Large Cooling Capacity: Available in a wide range of cooling capacities, from tens to thousands of RT, they meet diverse operating requirements and are widely used in large-scale central air conditioning systems, industrial cooling, and other applications.
Stable Operation: Screw compressors offer a compact design, smooth operation, and are equipped with multiple safety features, including high and low-pressure switches, phase loss, reverse phase, and overload protection, ensuring safe and reliable operation. Easy Maintenance: The device's structural design facilitates routine maintenance and overhaul, reducing maintenance costs for users.
Applications
Central Air Conditioning Systems: Commonly used in large office buildings, shopping malls, hotels, and other venues to provide a comfortable indoor cooling environment.
Refrigeration Industry: Used in the plastics, rubber, and chemical fiber industries to cool materials and ensure production process stability and product quality.
Electronics Industry: Provides precise temperature control in the manufacturing of semiconductors, LEDs, LCDs, and other electronics, protecting sensitive equipment from high temperatures.
Food and Beverage Industry: Used for cooling and refrigeration in food processing and beverage production, ensuring food safety and freshness.
Medical Equipment Industry: Used in the manufacturing of medical equipment to cool equipment and ensure its normal operation and service life.
