DEFENDER Example: Door dimensions: width 6m – height 5m Internal temperature: +18°C – External temperature: -5°C Average air speed (when the door is open): 1,2 m/sec . Calculation: In the above mentioned conditions, this is the heat loss (Qd) in 1h time when the door is open. Qd = 5 x 6 x 3600 x 23 x 0,3 = 745.200 kcal/h equivalent to about 866,52 kW In conclusion the heat loss is very high: this is the main reason of drastic falls of temperature in industrial buildings. Given such values, the pay-back for the cost of our air curtains installation is calculated in about two years.
