Air-to-water heat pumps suitable for cold climates | water production up to 75°C
Available in reversible or cooling-only versions, designed for residential, commercial, and industrial applications.
Allows modular systems of up to 5 units (up to 600 kW in cooling and 660 kW in heating).
Adaptation and Environment
- Reduced charge of natural R290 refrigerant, A3 class, environmentally friendly with low global warming potential (GWP = 3) and high thermodynamic performance.
- Robust and reliable design with integrated leak detection and ATEX extraction fan for maximum safety.
- With carefully designed insulation, the unit ensures proper protection and noise reduction, achieving ultra-quiet operation.
- Units equipped with intelligent control to ensure an optimal defrosting process.
Energy Efficiency
- Compact Full-Inverter units equipped with hermetic Scroll inverter compressor, electronic expansion valve, and EC fans, ensuring optimal seasonal performance (SEER/SCOP).
- Wide operating range with high efficiency and extended operating limits (full-load operation down to -20°C outdoor temperature).
- Partial heat recovery available, with the option to integrate the recirculation pump.
