Philadelphia-based Trent Inc. was incorporated on July 27, 1927, as a manufacturer of electrically heated industrial process equipment and heating elements. According to the company, craftsmanship is one of the keys to its success. Another strength is its family atmosphere, which reinforces a solid work ethic where attention to detail and quality are a matter of pride.

According to Miss L.J. Silverthorn, president and CEO, "[Trent's] 75 years of experience, coupled with highly trained dedicated employees and innovative product design, have positioned us as a leader in thermodynamics and temperature control."

Trent celebrated its milestone in April at a local conference center, where roughly 90 people -- including employees, board members and shareholders -- gathered for cocktails and dinner.
