Solutions of Illinois Inc. (ESI) was founded in 1987 as an energy management
company. After years of installing temperature controls made by other
companies we decided to design our own.
We started ESI Controls in 1994 with the
original planning for the AD 2000™ Temperature Control. We
wanted to create something more advanced and easier to use
than the products available from other companies at the
time. Together with the fine engineering
staff at Circom Inc. it became reality.
Now in its 28th year of production,
after many improvements and hundreds of successful installations we dedicate
this Web space to all that is... AD 2000™.
Enjoy your stay at ESI Controls.
