All-in-one combined air handling unit and reversible heat pump. The result is fresh air, heating and cooling in a 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. Installation is simplified if you opt to have the unit factory pre-filled, tested and ready to run. The unit is also available in a version for cooling only and is then called GOLD RX/C.
