Notes

Modular air-to-water heat pump with direct refrigerant evaporation in the air coolers, eliminating exchanger losses and cooling-circuit pumps for optimum efficiency. Designed for modern district heating production.

Direct expansion air coolers — highest efficiency of the air-source range. Platform uses 4 hydrocarbons selected per application: propane R290 (heat 30-65°C), isobutane R600a (50-95°C), n-butane R600 (70-120°C), isopentane R601a (90-170°C). GWP ~0.02. Up to 4 compressor units per module. Machine room <75 dB. Modbus TCP/IP. 100,000 h design life. FAT factory testing. H&V News Awards 2024 winner.
