Polytropic Heat Pump

An even more efficient heat pump that uses the more environmentally friendly R32 gas with a lower Global Warming Potential (GWP).

• Inverter operation with variable-speed brushless compressor and fan.
• High-end regulation with 7 information inputs for precise COP and noise level management.
• Titanium heat exchanger, "Blue Fins" corrosion-resistant evaporator,
• Automatic defrosting by 4-way valve.
• The SITY Inverter heat pumps offer:
  • Operation down to -15°C with preheating of the casing and condensate antifreeze system.
    
  • Improved COP thanks to an electronic expansion valve and precise management of compressor/fan speeds.
  • Simple and intuitive operation, the new digital display provides access to three operating modes.
• An environmentally friendly product: R32 gas, low power consumption, reduced noise level.

The 3 operating modes of the Sity Inverter Heat Pumps:

1. Boost Mode - Maximum Power: suitable for the early season temperature rise, maximum power and "inverter" operation approaching the set point.
2. Smart Mode - Self-Regulation: power and noise level adjust automatically based on the outdoor temperature and pool water temperature.
3. Eco-Silence Mode - Silence and Economy: COP and noise level are prioritized, the compressor and fan are slowed down to the maximum. The machine will have a very high COP and be quieter. Ideal cycle in the peak season or for night operation with minimal noise.
