Frequently Asked Questions

What makes CO2 (R744) a superior refrigerant?

CO2 is a natural refrigerant with a Global Warming Potential (GWP) of 1 and zero Ozone Depletion Potential (ODP). It is non-toxic, non-flammable, and does not require complex recycling processes, making it the most environmentally friendly option for modern heating.

Can the heat pump provide hot water in extremely cold climates?

Yes, this CO2 heat pump is specifically designed for low-temperature environments. It can operate efficiently at ambient temperatures as low as -25ºC while maintaining a high COP without the need for auxiliary electric heaters.

What is the maximum water temperature this system can produce?

The system is capable of producing hot water with an outlet temperature of up to 95ºC, making it suitable for specialized industrial requirements, hotels, and hospitals that need high-temperature sanitation.

How does Inverter technology save energy?

Our system utilizes full Inverter technology for both the compressor and motors. This allows the unit to adjust its power output based on real-time demand rather than running at 100% capacity constantly, resulting in significantly lower electricity consumption.

Is the system safe for indoor or residential use?

Absolutely. CO2 refrigerant is classified under Safety Group A1, meaning it is non-toxic and non-flammable. It is one of the safest refrigerants available for residential villas, apartments, and commercial beauty salons or spas.

What certifications do these units carry?

The units are fully certified with CE, CCC, and RoHS standards, ensuring they meet rigorous international safety, health, and environmental protection requirements.
