ETA began its Air Handling Units manufacturing in 1999 year under technical collaboration with Novair, Italy.

The Collaboration was for Five years and it ended on 2004.

Ten years of AHU manufacturing experience from the field and Indian conditions were adequate for ETA to advance the Art and Science of AHU Technology through its own Research & Development.

This has resulted in ETA being the First Indian AHU manufacturer who has successfully obtained coveted EUROVENT Certification for EHF 50 TB Model.

ETA is also one of the first to have its Cooling & Heating Coil ARI Certified.

AMCA Certified blowers are used by ETA for Air Handling Units.

The above certification Guarantee's user the performance of AHU as per Ratings / Selection Software.

This is the result of stringent testing of ETA make AHU's in Eurovent Accredited test laboratory in Germany. In addition, ETA AHU's with 50 mm thick Insulation has qualified for European Standard - EN 1886. This standard gives the casing performance in terms of Casing Leakage, Casing Strength, Thermal Conductivity, Thermal Bridging properties, Filter bypass & Sound. The Standards gives permissible Range under each Classification for each parameter and makes Five Classifications. ETA - AHU's meets the most stringent Norms in three out of Five and Second best on the remaining two parameters.

Following Table Explains:

These compliances ensures that ETA - AHU's are one of the most energy efficient units available in India.

In short, ETA has perfected the Arts & Science of AHU's technology and created a "Product - Internationally Accredited Engineering Marvel."
