Air curtain systems from Tekadoor

Warm, cold or recirculating air curtains, for public and commercial applications

Tekadoor, based in Langenfeld in the Rhineland, Germany, is an expert in door air curtains. Founded in 1981, the company produces modern air curtains with EC technology for all types of doors and gates used in European retail, commercial and industrial sectors. This also includes individual solutions for a controlled and balanced hot/cold air ratio in open or semi-open spaces.

Door air curtain technology

Air curtain technology and how it works

Tekadoor offers a wide range of air curtain products in order to fulfil all structural requirements. The TÜV Süd-certified door air systems are suitable for use in buildings where the entrance area needs to be kept open all year round. Depending on the type of equipment and the performance class, door air curtains can separate different thermal air currents from each other. This technology enables shielding from cold outside air during the autumn and winter months, and from warm outside air during the summer months – whilst maintaining a pleasant air and room temperature at the same time.

In industrial or commercial buildings, door air curtains are primarily for avoiding draughts and to create the required ambient temperature

1. to protect temperature-sensitive goods, and

2. to create a comfortable climate for personnel working in the hall where the loading and unloading zone is situated.

Depending on the entrance situation, air curtain systems can be installed either as suspended or standard standing units, or as a customized special solution. This enables the equipment to be integrated into doors or gates for more complex construction projects.
