Merkmale
Air-to-water heat pumps suitable for cold climates Water production up to 77ºC
Reversible or cooling-only units with a thermal power ranging from 47 kW to 91 kW, designed for commercial applications.
Optimized for the use of R290 refrigerant and Full-Inverter technology, these units are part of the new PRO Series developed by KEYTER.
Adaptation and Environment
- Reduced charge of natural R290 refrigerant of A3 class, which is environmentally friendly with a low global warming potential (GWP=3) and high thermodynamic performance.
- High-temperature water production.
- The robust and reliable design integrates leak detection and an ATEX extraction fan for maximum safety.
- With careful insulation, they ensure proper equipment protection and noise reduction, achieving ultra-quiet operation.
- The units are equipped with intelligent control that ensures an optimal defrosting process.
Energy Efficiency
- Compact Full-Inverter units are mounted with semi-hermetic piston compressors and high-quality EC fans, ensuring the best seasonal performance (SEER/SCOP).
- High-efficiency heat exchangers.
- These units have a wide operating range with high efficiency and extended operating limits, functioning at full load down to -25ºC outdoor temperature.
