How a Russian immigrant and the proceeds of a pawned wedding ring founded a sustainable cooling solution powerhouse.

Over 80 Years of Innovation

After fleeing Moscow with his family, Baltimore Aircoil Company founder, John Engalitcheff Jr. immigrated to Baltimore around 1924. Soon after, the Engalitcheffs sold nearly everything they owned to send him to Johns Hopkins University to study engineering. Upon graduation in 1930, he was hired at a local refrigeration company.

In 1938, he hand-built an AC coil in a garage and pawned his wife Virginia’s wedding ring to start Baltimore Aircoil Company. He went on to develop 47 patents, 23 of them in the field of evaporative cooling devices. In 1996, he was inducted into the ASHRAE Hall of Fame.

Today the pioneering spirit of John Engalitcheff Jr. lives on in the innovative products and commitment to excellence of a company that continues to lead the way in the development of truly sustainable cooling solutions.
