High Temp Water Source Heat Pump Unit
As one of China's earliest professional manufacturers of purification air conditioners and HVAC equipment, Sujing specializes in R&D, production, sales, and installation. We operate two core segments: air conditioning systems and heat pump systems. The heat pump line includes CO2 heat pumps, cascade variable frequency units, air source (chilled water) units, water-cooled chillers, industrial screw units, air-cooled modules, and drying units.
Our products are widely applied in industry, agriculture, commerce, transportation, and aerospace, as well as in specialized fields like green heating, coal mines, oil fields, livestock farming, agricultural drying, and biomedicine. They are exported to over 30 countries, including the U.S., Finland, the Netherlands, Canada, and Brazil.
SJS-RSG High Temp Heat Pump Units Series
Performance characteristics
· Cooling and Heating: One Machine for Multiple Uses
It can provide cooling capacity continuously while heating,which is more convenient to use,occupies a smaller area and has a lower investment cost.
· High Efficiency and Energy Saving: Save 85% of Electricity
The comprehensive energy efficiency ratio of cooling and heating can reach up to 8.0,which saves 85% of electricity compared with the traditional combination.
· High Temp Water Outlet: Wide Range of Uses
The hot water outlet is up to 98ºC(R1234ze(E)),and it can also provide low temperature chilled water at a minimum of 5ºC,which is suitable for various occasions with hot and cold needs.
· Safe and Reliable: Durable
It does not directly contact the heating medium,fundamentally eliminating safety hazards such as flammability,explosion,leakage,etc.,and has a service life of more than 15 years.
