About Quantech Chillers

Quantech chillers are a line of air-cooled and water-cooled chillers available exclusively through the independent rep channel.

All chillers are AHRI certified and meet other industry-wide standards such as ETL, UL, and ASHRAE.

That experience ensures that Quantech chillers are built with the most important, intelligent features and start off with a track record of exceptional efficiency and reliability.
