AIR-TO-WATER HEAT PUMPS – PRO SERIES – ZIRAN PRO KWR

Air-to-water reversible heat pumps

Reversible or cooling-only units with a thermal power ranging from 41 kW to 253 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.
