TTL Torluftschleier GmbH

TTL greenline  is an expression of our commitment to the environment and stresses our future-oriented promise and extensive know-how in the use of secondary energies. Proven system solutions in combination with flexible model variants of TTL air curtain systems enable the use of a wide variety of secondary energy types.


Every building has its own specific technical requirements and the building services must be custom-adapted to these. This also applies to air curtain systems, whether in combination with heat pumps or with VRV/VRF systems.

We already support you during the system planning phase - independent of the supplier - in the selection of suitable air curtain units that fit your building technology. So simply contact us!

Our goal is the efficient interaction of all components for a concept that optimally saves energy. Together with you, we plan and implement the most economical and cost effective air curtain solution, taking into account freely selectable components and the building’s individual ventilation requirements.

In principle, our energy-saving concepts can be implemented in all our air curtain system types. So browse our product pages - we need to examine the technical limits together, such as those due to required heat exchanger surfaces or necessary installations for condensate treatment.


Our . The reduced energy requirements of these devices can be covered by correspondingly small energy sources or by renewable energies. For extreme situations, a second energy source is used temporarily.


The tried and tested TTL eQomax concept is the result of many years of developing climate-friendly air curtain technology using renewable energy

As a visionary manufacturer of air curtain systems, we develop, plan and manufacture the trend-setting TTL eQomax system in series today, according to the latest guidelines with a view to the future.

Intelligently linked into the refrigeration/air conditioning network of the building technology, eQomax ensures 100 % sustainability in the entrance area. This saves energy during a high customer frequency and full function. It reduces CO2 emissions and energy consumption to a minimum.
