Frequently Asked Questions

What are the environmental benefits of using CO2 (R744) refrigerant?

CO2 is a natural refrigerant with an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1. It is non-toxic and non-flammable, making it the most environmentally friendly choice for next-generation heating.

How high can the water temperature reach?

This CO2 heat pump can reach a maximum output water temperature of 95ºC, which is significantly higher than standard EVI heat pumps, making it ideal for industrial and specialized commercial use.

Can this unit operate in extremely cold climates?

Yes, the system is designed to work efficiently in ambient temperatures as low as -25ºC. It maintains a high COP even in low-temperature conditions without needing auxiliary electric heaters.

How does Inverter technology improve performance?

The system utilizes full inverter technology for both the compressor and motors. This allows the unit to adjust its output based on demand, leading to significant energy savings and more stable water temperatures.

What applications is this heat pump suitable for?

It is versatile and suitable for luxury villas, hotels, hospitals, student apartments, beauty salons, and large-scale facilities like swimming pools and saunas.

Is the unit safe for indoor installation?

Yes, CO2 is classified under Safety Group A1. It is a natural, non-toxic, and non-flammable gas, ensuring high safety standards for all types of building installations.
