Myth no 5: Automatic doors are energetically inefective

False. The truth is the opposite. Automatic doors prevent wasting when it comes to central heating and air conditioning.

Opening and closing automatic doors is a quick operation that minimizes heat loss from the building in winter and ensures greater efficiency of air conditioning in summer. The doors only open when a person appears in the sensor's field of view, and they close safely after the person passes through.
When using ordinary doors, it often happens that the user forgets to close by mistake. If the doors then remain open or partially closed for a long time, a considerable amount of warm or cooled air can escape. The automatic door closing system easily puts an end to such situations.

Different types of automatic doors offer different advantages. For example, the wide entrance opening of linear automatic sliding doors has a favorable effect on air flow in the building. Revolving doors, on the other hand, prevent drafts and direct exchange of air outside and inside. All of this results in energy savings.

There is also a belief that operating automatic doors consumes a large amount of electricity. Let's clarify this with an example of linear doors with a TORMAX iMotion 2202 drive. Assuming that the passage width of the automatic doors will be 1 meter, the doors open for 1 second, close for 1 second, the electricity price is 3.50 CZK/kW, and the drive power is 190 W (the highest possible for this model), one opening/closing cycle costs us about 0.0004 CZK, which is 40 CZK for 10,000 cycles. Of course, it depends on the utilization of the automatic doors and the setting of the opening speed, but in the end, the expenses for electricity should be returned to you several times in the form of the savings mentioned above and the comfort that is priceless.
