Frequently Asked Questions
What is the main advantage of using R32 refrigerant?
R32 is an eco-friendly refrigerant with a lower Global Warming Potential (GWP) and higher efficiency compared to traditional refrigerants, ensuring better performance and environmental protection.
Can this heat pump operate in cold weather?
Yes, the unit is designed to operate efficiently within an ambient air temperature range of -5°C to 43°C, featuring a reversible defrosting function for reliable winter operation.
Why is a titanium heat exchanger important?
Titanium is highly resistant to corrosion from pool chemicals like chlorine or salt, significantly extending the lifespan of the heat pump compared to standard exchangers.
Is this unit suitable for large commercial pools?
Absolutely. With heating capacities ranging from 31kW up to 90kW, these units are ideal for hotels, gyms, public swimming pools, and large villa complexes.
Does the unit support both heating and cooling?
Yes, it is designed with a dual-mode function, allowing you to heat your pool during winter and cool it down during hot summer months for a perfect temperature year-round.
What kind of power supply is needed?
This commercial series requires a 380V/3pH/50Hz power supply to ensure stable and powerful performance for industrial-scale applications.
