SG-Ready function

The Smart Grid function enables heat pumps to interact intelligently with the electricity grid. Appliances with the SG-Ready label can be switched off temporarily if required, e.g. in the event of high peak loads in the grid, or activated if there is a surplus of electricity in order to efficiently convert excess energy into hot water. Integration into the smart grid takes place via special interfaces that can receive signals from energy suppliers, photovoltaic inverters or smart home systems. This not only promotes more efficient use of renewable energy, but also supports the stability of the power grid.

Complete DC inverter technology

The R290 heat pump uses DC frequency conversion technology to improve heating performance at low temperatures. In cold climates, the heating capacity is 30% higher than conventional heat pumps.

-25℃ Low ambient temperature

By combining R290 natural refrigerant and inverter heating technology, the new R290 monobloc heat pump can operate at -25°C to 45°C, ensuring a high COP and reliable stability. The water outlet temperature reaches 75 °C without electrical heating.

High safety and explosion protection

SPRSUN R290 heat pumps use high-quality parts, such as Panasonic R290 special safety compressor, CAREL explosion-proof electronic expansion valve, explosion-proof relays, Grundfos water pump and other high-quality components to ensure safety.

Built-in discharge valve and pressure relief valve: In case of R290 refrigerant leakage, the refrigerant can be discharged through this valve.

Safe electronic control design: The layout of the control box of the R290 heat pump has been optimized. It has built-in fuses and mechanical high-voltage switch protection to achieve multiple overcurrent protection.

Intelligent CAREL control system

Thanks to the integrated 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 with the curve graph display and the water flow display function is included in our R290 air to water heat pump.

Equipped with a smart touch screen that works via Wi-Fi, the R290 heat pumps allow users to control the device remotely via an APP.

The intelligent control system supports smart defrost and automatically switches to defrost mode when conditions are met, improving the reliability and efficiency of the R290 heat pump.
