ESD Stays on Cutting Edge for 50 Years

Throughout its 50-year history, ESD has been involved in a number of important innovations.

For instance, people take for granted that commercial office buildings will be cool when needed, but ESD’s engineering work with Unicom Thermal Technologies’ two chilled-water plants in the 1990s broke new ground.

The facilities – the largest ice-based district cooling system in the world at the time, which served more than 8 million square feet of commercial office space and involved 25,000 tons of cooling – featured advanced technology that sent chilled water to a building before returning it warm to the facilities to be chilled again. The process eliminated ozone-depleting refrigerants.
