What happens in your building with the door open?

In factory halls, the Airwall permanently prevents the influx of cold air masses and allows barrier-free work on open doors. The employees no longer suffer from drafts, no more colds in the winter time and also the energy consumption for heating the hall is significantly reduced.

12 m² (Area of ​​the gate) x 2 m/s x 3.600s (1 h) = 86.400 m³/h  This means that in one hour 86.400 m³ / h of air flows into your building at a temperature of 0 ° C, which has to be reheated to room temperature of 20 ° C. As you know, you can generate about 10 kWh / l of heat with one liter of oil or 1 m³ of gas. This means: volume (86,400m³) x 0,36 (constant³) x temperature difference (20 ° C) (K) = 622,000 W.≙ 62.2 l fuel oil With an assumed heating oil price of approx. 0.92 €, the energy expenditure for heating up to 20 ° C hall temperature costs 57.22 € / hour. Expenses for the operation of an airwall system: fan air volume: 9000m³ / h, electr. Drive: 4,5 kW 9000m³ / h x 0,36 x 20K = 64 kW (Q) 6,4 l oil x 0,92 € = 5,88 € + 4,5kW electr. x 0,18 € = 0,81 €. Total cost = 6,69 €

Thus: 57,22 € – 6,69 € = 50,53 € saving
