TEDDINGTON What is Air Curtain Technology?
It's definitely more than only hot air.
Air curtains, castles in the air, hot air …
What are air curtain systems used for?
We all know the physical effects The first air curtain systems used
of hot air: “Hot air rises” – a law of warm rising air at the permanently

principle. Or rather, we have taken
the lead, and have opened up many
new applications.
Almost everywhere, where

the systems produced by Teddington

comfort – and that in well-nigh
innumerable fields of applications.
