TripleAqua is a world wide patented heat pump system, designed for heating and cooling of medium and large size buildings. The system operates on pure water and the natural hydrocarbon refrigerant propæne and is perfectly suitable for both new and refurbished buildings. Part of the innovation is the ultra efficient thermal transfer and the easiness of the system. Thanks to its flexible design and energy efficiency improvements, TripleAqua allows for significant reductions in construction costs of 25% and decreases in operation costs by at least 50% compared to other heat pumps. The TripleAqua system will officially be launched at ATMOsphere Europe 2015.
