Sustainable, modular & energy efficient

Pioneering Underfloor Air Conditioning Since 1993

Shaping the future of HVAC in award-winning, landmark projects worldwide. For over 30 years, AET has delivered smarter, more sustainable, and highly adaptable underfloor air conditioning solutions.
We’re not just a manufacturer, we’re innovators driving the future of smarter workspaces.

What is Underfloor Air Conditioning?

A smarter way to heat and cool modern spaces.
UfAC uses the raised floor void as a plenum for delivering conditioned air via floor-level Fantile™ units.
Air is drawn back through high or low-level returns, filtered and recirculated for continuous comfort.
It’s flexible, efficient, and designed to adapt to your building.

From refurb to new build, we help create intelligent, flexible workspaces from the ground up.
