R290 DC Inverter Heat Pumps

Made with sustainable R290 refrigerants, the global warming potential (GWP) is as low as 3.3, our R290 heat pumps contribute to eliminating carbon emissions. It is rated with an A+++ energy label. The unit can save 50%-80% of energy than others.

• The front panel of SPRSUN R290 heat pump is made of blister panel, rear, and side mesh panels are made of sheet metal, which can support higher requirements for customized appearance.
• R290 heat pump, with spiral injection molded mesh cover, in line with the aerodynamic shape, is conducive to the flow of noise reduction.
• Large plastic handles on the rear panel are designed for easy access to power cables and maintenance.

• Built-in consumption monitoring module, you can view real-time and historical voltage, current, power, and COP data in the Carel Controller. The power consumption is more intuitive through curve graph display, and the water flow display function is added.
• Equipped with an intelligent touchscreen that works through WIFI, the heat pumps R290 allow users to control the device remotely through an APP.
• The smart control system supports intelligent defrosting, automatically entering the defrost mode when the conditions are met, thus improving the reliability and efficiency of the R290 heat pump unit.

• SPRSUN heat pumps R290, use first-class parts, such as Panasonic R290 special safety compressor, CAREL explosion-proof electronic expansion valve, explosion-proof relay, Grundfos water pump and other high-quality components to ensure safety. 
• Built-in exhaust valve & pressure relief valve: When there is an R290 refrigerant leakage, the refrigerant can be discharged through this.
• Needle valve in the structure adopts a sealing method. Louvers on the middle partition and convection holes on the chassis can increase air convection and prevent refrigerant from reaching explosive concentrations.
• Safe electronic control design: The layout of the R290 heat pump electrical box has been optimized and the wiring is more reasonable and tidier. It has built-in fuses and mechanical high-voltage switch protection to achieve multiple over-current protection.

The integration of an "SG-Ready" ensures that the SPRSUN R290 heat pump communicates with the smart grid, allowing for more excellent energy optimization and grid integration.

• Optional day and night modes - allows low-frequency operation and low noise in night mode for a more comfortable environment;
• All-round noise reduction - Reinforced parts to reduce vibration, coupled with dual noise reduction of the compressor and full coverage of sound insulation material on the inner panel, make the R290 heat pump work quieter.
• Use spiral injection-molded grille to diverse airflow and reduce noise.

R290 air source heat pump adopts DC frequency conversion technology to improve low-temperature heating capacity. In cold climates, the heating capacity is 30% higher than traditional heat pumps.
