At a world premier organised at ATMOsphere Europe on 16 March 2015 in Brussels, Menno Van der Hoff unveiled for the first time the TripleAqua, a patented natural refrigerant heat pump system using propæne as the refrigerant. Designed for heating and cooling of medium and large size buildings, this cutting-edge technology allows for reductions in energy consumption up to 50% and can bring a building to energy label A+++, the highest attainable level in energy efficiency. <span style="col
Heat, cool and store in one go. TripleAqua is a new, revolutionary natural heat pump system, Van der Hoff explained at ATMOsphere Europe.
Tripleaqua has thermal internal storage for cooling and it can simultaneously heat and cool to double the efficiency with water moving the energy around. Van der Hoff said.
