Air curtains are an essential element of the ventilation system to ensure energy savings in building entrances. And if these air curtains are heated in a heat pump system, it makes them highly efficient devices.

Our distributor in Italy, Eurotecno, has carried out a high energy saving project by installing an Airtècnics air curtain with EC fans, connected to a heat pump system in the doorway of a Scorpion Bay men's fashion shop.

High energy savings

Heat pumps have the ability to transfer energy from the environment into a heat exchanger, using very little electrical energy from the mains, making it a high energy saving system with low environmental impact. Airtècnics DX air curtains incorporate a direct expansion coil that, connected to a heat pump, is offered as a low consumption alternative to the classic electric heating or hot water heating coils.

The running costs of a heat pump air curtain are lower than those of an electrically heated air curtain, as can be seen in the following example for a typical door:

Under these conditions, it can be concluded that the payback period for the installation of a heat pump air curtain compared to electric heating elements is just over one year (13 months). A heat pump air curtain saves energy and CO2 emissions to the environment: in one year, 12,765 kg less CO2 are emitted and the economic savings are more than € 11,000.
