Cooling Capacity Range: 559kW~1677kW Chilled water outlet temperature: 5~20℃

The secondary refrigerant passes through the heat exchange tube, the refrigerant flows in the shell side and completely immerses the heat exchange tube, and evaporates outside the heat exchange tube after absorbing heat.

Our falling film evaporator are compact and easy to install, suitable for chillers with multiple compressor systems.

The water-to-water heat exchanger is a heat exchange and conduction device with a wide range of uses. Water to water shell and tube heat exchanger is mainly composed of shell, tube sheet, tube bundle, baffle and box body.

H.Stars heat pump includes both cooling and heating function, cooling in summer and heating in winter or hot water in transition seasons, one unit has muti-functions. With more than 20 years experiences of manufacturing heat pump and hot water units, H.Stars Group has focused on R&D and successfully supplied various types of heat pump and hot water units to the society.

Modular evaporator + condenser is an integrated unit heat exchanger composed of evaporator and condenser as a modular combination industrial assembled shell and tube heat exchanger.

This explosion-proof ground source heat pump unit uses explosion-proof materials and is used in fishing boats. Features: Intelligent control, high efficiency and energy saving, stable operation

Customized chiller with water pump and AHU. It can supply clean cooled air to the designated area directly. Using chilled water system, temperature can be controlled preciously and stable. Unit is easy to install and save installation spaces, integrated design makes unit very convenient and save engineering works.

H.Stars dual source heat pump adopts an evaporative condenser, which uses the evaporation of water to absorb latent heat to condense the refrigerant vapor. The heat released from the evaporation of refrigerant transferred to the outer water film by the oil film, pipe wall and dirt, and then the heat is transferred to the air by the evaporation of the water. Dual source heat pump has the advantages of less water consumption, low sound level, energy saving and environmental friendly. It is especially suitable for use in areas where water is scarce and the weather is dry.

H.Stars air source cooling and heating chillers,also called Tri-function chillers have five major functions: cooling, heating, hot water, cooling with hot water, and heating with hot water. It can be used in summer for cooling, and at the same time to produce hot water, or just for cooling alone; in spring and autumn when there is no need for cooling and heating, it can be used to produce hot water; and it can be used for heating and producing hot water in winter. The integrated microcomputer control system enables them to automatically identify and adjust operating conditions according to actual water temperature and purpose of use. In addition to fully automated intelligent control, they may also be subject to remote management program, in which remote service is made possible through feedback of system operation information. These energy-saving, environmentally friendly, multi-functional, compact structured, space saving, and easy-to-install systems are suitable for hotels, villas, hospitals, schools and other places with demand for cooling and heating.

*Liquid sprayed from above is to form a thin film on the surface of the heat exchange tube to obtain the best heat transfer effect. *The liquid separation and deforming device is national patented. *With no superheat requirement of refrigerant vapor the evaporation temperature can be greatly increased. *Achieve 30% higher heat transfer coefficient and 35% less refrigerant charge volume than flooded evaporators. The spray type evaporator is suitable for screw, centrifugal, magnetic bearing and other types of compressor.

Ambient temperature -25 ~ -35℃ to produce 50℃ hot water,  Hot water temperature range : 35- 50℃ 

316L stainless steel water to water shell and tube heat exchanger can be customized by UAR(Guangzhou United A/C & R CO. Ltd . The shell side and tube side of the shell and tube heat exchanger are made of 316L stainless steel, which is suitable for various water quality and corrosive environments.

H.Stars r1234ze heat pump high temperature heat pumps is an equipment that transfers low-grade heat energy to high grade heat energy. It replaces the boiler and become a more energy-saving and environment-friendly high temperature industrial heat pumps.

R1234ze shell and tube evaporator and condenser has been developed by UAR recently, which has helped chiller maker factory to increase the efficiency and calculate the accurate heat transfer.

For cold storage, food processing, quick freezing and industrial cooling. The product is manufactured by adopting the combination of famous brand compressors and electronic control components. It is equipped with high-efficiency fin condenser and evaporator. The unit is controlled by microcomputer and equipped with various protection functions which is high reliability, and can exert the highest efficiency in the actual working conditions.
