History of E-Tech Heat Recovery

Our Beginnings

E-Tech Heat Recovery Systems (E-Tech, Inc.) was founded in 1976 with a clear mission: to engineer reliable, application-specific solutions that help industry capture and reuse waste heat. From the beginning, E-Tech focused on custom design rather than standardized products, allowing each system to be tailored to the operating realities of its customer.

The company’s technical foundation is rooted in deep industry experience. E-Tech’s founder previously served as chief engineer for Kentube Engineered Products in the mid-1970s, bringing proven design principles and a strong understanding of economizer and heat-exchanger performance into the new company. This heritage shaped E-Tech’s emphasis on durability, thermal efficiency, and practical field serviceability.

Over the decades, E-Tech has designed and manufactured thousands of economizers and heat-recovery systems for a wide range of applications. Its capabilities expanded beyond traditional economizers to include condensing economizers, waste-heat boilers, heaters, and other custom heat-exchanger components used in industrial, institutional, and utility environments. Each project reinforced the company’s reputation for engineered-to-order solutions backed by hands-on technical support.

A significant milestone occurred in 2019, when E-Tech acquired the intellectual property and specialized cylindrical manufacturing equipment of Kentube Engineered Products. This acquisition formally united E-Tech’s historical engineering lineage with Kentube’s well-known designs, enabling E-Tech to support existing Kentube installations while continuing to develop new heat-recovery solutions.

Today, E-Tech Heat Recovery Systems continues to operate from Tulsa, Oklahoma, serving customers who require dependable, custom-engineered heat-recovery equipment. Guided by decades of experience and a commitment to practical engineering, E-Tech remains focused on helping customers improve efficiency, reduce energy waste, and extend the life of their thermal systems.
