All-in-one combined air handling unit and reversible heat pump. The result is fresh air, heating and cooling in an unrivalled slimline and energy-efficient design. Planning is simplified by the fact that we have already done the integration between the heat pump and the air handling unit for you mechanically and in terms of control. The compact dimensions also save you valuable space. Installation is simplified if you opt to have the unit factory pre-filled, tested and ready to run. Commissioning is fast and smooth, as all the functions are controlled directly from the GOLD unit’s intuitive hand-held terminal.
