Aircraft Ground Energy System AGES

For over 40 years, we have been manufacturing and assembling stainless steel process engineering plants, equipment, tanks and pipelines for the pharmaceutical and chemical industries, food and beverage industries, machinery and printing industries, as well as for water supply systems, municipal facilities and airports.

In the field of Airport Systems, we offer the world‘s first totally integrated system for the supply of electrical power (400 Hz) and pre-conditioned air (PCA) to aircraft on the ground: the Aircraft Ground Energy System AGES.

In the last decades, the cooling of the aircraft has been conventionally carried out with DX equipment, whereby optimal cooling of the Aircraft cabin was never achieved. ISTinox DXi stands for a conventional, stand-alone PCA device (DX) with the difference that we revolutionize the cooling of the aircraft with an innovative (i) new concept and thus ensuring the well-being of the passengers and the aircraft crew under all conditions.

Through the use of high-quality materials, ISTinox Pre-conditioned Air products have an above average service life with low maintenance and minimal pressure and temperature losses. In addition, the use of stainless steel allows compliance with the highest hygienic standards.

We are thrilled to announce that we have successfully won two bidding processes for PCA (Pre-Conditioned Air) systems at Munich and Frankfurt Airports. This achievement highlights our expertise and commitment to delivering high-quality solutions in airport infrastructure. We are excited to collaborate with these prestigious airports and look forward to contributing to the smooth operation and passenger comfort.

Customers who have trusted us for many years, thank you!

"We are more than satisfied with the Pre-conditioned Air systems from ISTinox, which have been installed in 1999, and we have not had any problems within the over 17 years of operation at the dock E. The products are still in use, virtually maintenance free and no parts had to be replaced or substituted." Bruno Asal, Head of the HVAC Airport Zurich
