Product Description JIANGSU SUJING GROUP CO.,LTD. High Efficiency CO2(R744)heat pump water heaterAs 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.Product DescriptionEnergy-efficient CO2 (R744) Heat Pump Water Heater for Cosmetics factoriesupdated in 2025-09-03Sujing Customizable Energy-efficient CO2 (R744) Heat Pump Water HeaterThe compressor absorbs low-temperature and low-pressure gaseous carbon dioxide refrigerantfrom the evaporator,and then compresses it into a high-temperature and high-pressuresupercritical fluid. This fluid enters the gas cooler to exchange heat with water, where it is cooledinto a high-pressure fluid and releases a large amount of heat. The water absorbs the releasecheat and the temperature continues to rise, After the high-pressure fluid is throttled andreduced in pressure by the expansion valve, it absorbs the heat in the surrounding air andevaporates into a low-pressure gas through the action of the fan in the evaporator, and is thensucked into the compressor for compression. This cycle is repeated to produce hot water. Operating PrincipleExcellent high-temperature heating performance: the highest water output can reach more than 90°C.Excellent low-temperature performance: high-temperature hot water can still be produced at an ambient temperature of -30°C.First-level energy efficiency: high efficiency, standard COP not less than 4.6.Wide application range: can work normally in an ambient temperature of -30°C~43°c, suitablefor producing domestic orindustrial hot water.Product Parameters Sujing Customizable Energy-efficient CO2 (R744) Heat Pump Water HeaterModelSJKRS-28II/CSpecifcations7.5 HPPower supply380V/3P/50HzHeating modeDirect heating/ CirculationStarndard working conditionsHeating capacity28.1 kWinput power6.1COP4.6Hot water flow0.6High temperature working condition Heating capacity23.9 kWinput power7.5COP3.2Hot water flow0.27Low ambient temperature Heating capacity15.7 kWinput power5.8COP2.7Hot water flow0.28ComponentWater pipe connectionDN20Water heat exchangerPlate / Shell and tube heat exchangerAir heat exchangerCopper tube aluminum finCompressor typeSemi-closed reciprocatingOperation panelColor touch screenMax. water outlet temperature90oCRefrigerantR744(CO2)Design pressure15MPa(HP)/8MPa(LP)Dimensions(length * width * height) mm1450*950*1450Noise≤56Weight550ApplicationWater supply temperature5~40oCWater supply pressure0.05~0.4Water outlet temperature55~90oCMax. flow rate1.2 m3/hAmbient temperature-30~43oCRemarks:1) Standard working condition: ambient temperature DB 20°C/WB 15°C, initial water temperature on the user side 15°C, and final water temperature 55°C;2) High-temperature water outlet working condition: ambient temperature DB 20°C/wB15°C, initial water temperature on theuser side 15°C, and final water temperature 90°C.3) Low-temperature working condition: ambient temperature DB-12°C/wB-14°C, initial water temperature on the user side 9°C and final water temperature 55°C.4) Please refer to the unit nameplate of installation manual for the unit on-site power distribution and wiring. 5) Specifications are subject to change with product improvements, please refer to the actual product.6) Customization is available according to the customer's actual requirements.Recommended ProductsView more products,you can click product keywords...AHUsDehumidifiersSimultaneous Heating&Cooling unitHot water UnitsChillers Main ProductsHot Products Company ProfileJiangsu Sujing Group Co., LtdDedicated to overall solutions for equipment manufacturing in the field of dehumidification and environmental protection.History: Established in 1969, state-owned high-tech company Size: 130,000 square meters Employees: 1200+Chiller Performance Testing CenterThe testing center is equipped to evaluate both water chillers and water/ground source heat pumps, simulating year-round operating conditions.
