Low Temperature Air Source Heat Pump with Screw Compressor
H.Stars has created a special air source single / double compressor heat pump unit that perfectly caters to the cold weather in the north for efficient central heating of 2000-10000 square meters in residential and commercial areas. Low ambient temperature is no barrier for this product; it can even maintain an output of up to 60 ℃ when temperatures plummet to -35 ℃ and and up to 70 ℃ when the ambient temperatures drop to -25 ℃. It is specifically suited for heating replacement requirement of old city areas. This special heat pump with screw compressor is an ideal solution to all the smog control and boiler replacement needs.
This air source heat pump hot water unit uses a special low-temperature compressor, available in two varieties - scroll and screw type. With modular design, our heat pump units can be used independently or linked together. Therefore, it is both flexible and efficient, making it well-suited for areas with temperature needs between 35-50 ℃ at ambient temperatures of -25~35℃. It also has both heating and cooling capabilities and produces hot water up to 50 ℃, giving it the versatility to meet a wide range of needs.
