The screw typed water source heat pump unit adopts screw compressors, one system replaces the original boiler and air conditioning system to save a lot of energy while reducing the initial investment in equipment. it can be used for cooling and heating both in commercial & industrial buildings which save energy by 30%-80% compared with a central air conditioner during operation. The unit can provide refrigerant such as R1234ze & R134a. R1234ze Refrigerant advantages:ODP value is 0, GWP value is 6, chemical properties are stable, environmental protection, can reduce 99.6% It is quite easy for installation with one-key start and stop, intelligent Siemens PLC control

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

This project is designed for Food Processing Plant in Southeast Asia, which is used to provide maximum 75℃ hot water to the machine on the food processing process. According to actual need of customer, this project was advised to use R1234ze refrigerant as medium to achieve maximum 75℃ hot water. It’s low gwp refrigerants r1234ze(e) and r1234ze(z) for high temperature heat pumps.

The Water-cooled chiller and Water source heat pump unit adopts screw compressors,one system replaces the original boiler and air conditioning system to save a lot of energy while reducing the initial investment in equipment. it can be used for cooling and heating both in commercial & industrial buildings which save energy by 30%-80% compared with a central air conditioner during operation.

High temperature air source heat pump： ▽Using air as heat source ▽Outlet water temperature 55℃—95℃ ▽Ambient temperature -30℃—55℃ ▽90℃ water outlet temperature, energy efficiency ratio 2.3 ▽Suitable for high temperature heating

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.

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.

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

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.

low ambient temperature scroll air source heat pump unit operates stably under the environment of -25℃ to 35℃. It adopts air as the heat source without pollution emissions, and can produce 55℃ hot water to meet the demand of hot water of 35℃-50℃. With heating function, it is suitable for heat supply modes of direct heating or floor heating.

H.Stars low ambient temperature air source heat pump can be divided to scroll and screw type of heat pumps ,which is flexible for different applications of cooling and heating at very low ambient temperature -25 ~ -35℃ to produce 50℃ hot water.
