This CO₂ heat pump unit is engineered for sustainable, high-performance operation, using the natural refrigerant R744 to support green energy goals with zero ozone depletion and ultra-low global warming impact. It delivers consistently high outlet-water temperatures, handling inlet ranges from 5°C to 55°C and producing hot water up to 95°C. Designed to work reliably in harsh climates, the unit operates stably in ambient temperatures from –35°C to 45°C. Its integrated design provides both heating and cooling — producing chilled water or antifreeze fluid while simultaneously generating high-temperature hot water. With advanced technology and optimized efficiency across the full operating range, the system achieves exceptional energy performance with efficiencies reaching up to 10.0.
