THE HISTORY OF  HEIL and our developments in FRP Composites

The Year 1929

Carl Heil forms HEIL & Co.

Carl Heil formed HEIL & Co. in Cleveland, Ohio. HEIL began with the production of corrosion resistant coatings and linings for the steel and metal finishing industries.


Fiberglass reinforced plastics change the way things get built.

Owens Corning of Toledo, Ohio worked with the US Military to develop fiberglass reinforced plastics (FRP) and prototyped the first fiberglass boat hull. Similar technologies were then used to produce polyester resins, which became a main building material of pleasure boats. Increased demand for resins and reinforcements, including the first BisA corrosion resistant resin and C type surface veil, broadened the applicability of of FRP as a corrosion resistant material. HEIL engineers closely followed these developments, ultimately introducing FRP materials to HEIL customers as an alternative to lined steel and coatings.


HEIL leads the way with FRP fan designs.

HEIL pioneered the development of three FRP corrosion resistant fan designs. A facility was opened in Berea, Ohio for the development, design, and manufacture of products made from FRP to be marketed to customers in the steel, chemical, and metal finishing industries.


HEIL develops the first FRP Spray Tower countercurrent scrubber.

PS 15-69 is published.

HEIL staff helps author national standard PS 15-69. The 50’s and early 60’s were an era of exponential growth in the use of FRP composite materials prompting major fabricators, end-user and material suppliers to recognize the need for design, fabrication, and quality standards. HEIL staff organized the committee for the first FRP design and fabrication standards, TS122C, which became the National Bureau of Standards Product Standard 15. Because of standardization, the bureau was able to respond to user demand and develop halogenated and chlorendic resins with fire retardant qualities in an FRP laminate and a flame spread testing/rating system ASTM E-84.


HEIL patents HEILEX Tower Packing Media.

The United States Environmental Protection Agency promulgates the Clean Air Act, a federal law regulating air pollution from mobile and stationary sources. HEIL developed new air pollution control technologies to bring customers into compliance with regulations. Packed tower scrubbers, cyclones, and mist eliminators were the early control technologies.


HEIL is acquired by Dart Industries.

The early 70’s saw the development of vinyl ester resins, which opened FRP composite applications to many additional solvent, chemical, and high-temperature applications. HEIL had fabrication plants in Cleveland and Avon, Ohio, Bartow, Florida, Houston, Texas, and Penns Grove, New Jersey, as well as with six international licensees. It is during this period that HEIL is acquired by Dart Industries.


HEIL is acquired by Xerxes Corporation.

HEIL experiences growth in the municipal and industrial markets for fans and scrubbing systems.


HEIL staff helps write the SMACNA Thermoset FRP Duct Construction Manual.

The SMACNA Thermoset FRP Duct Construction Manual became the standard design manual for industrial fiberglass ducting used by fabrication shops throughout the United States and is still used today.


HEIL / Xerxes receives a US patent for the backward inclined fan impeller.

With design efforts led by HEIL engineer David Correll, HEIL/Xerxes patented the FRP backward inclined fan impeller in 1999.


Xerxes sells HEIL Process Equipment assets to division leader Robert Hahn.

The new company, HEIL Process Equipment LLC, consolidated and moved manufacturing to Sheffield, Ohio, where it focused to specialize in air pollution control equipment. HEIL offices, however, remained at the historic location in Avon, Ohio.


HEIL is sold to private investors with extensive experience in air pollution control systems.

Considered a tremendous asset to the newly named HEIL Engineered Process Equipment Inc., all office and manufacturing employees were retained during the transfer of ownership.


HEIL welcomes chemical engineer Arlene Miller to the team as General Manager.

In 2016, with new offices in North Ridgeville, Ohio, Miller joined the team, bringing extensive experience in air pollution control design and manufacturing.


HEIL expands technical staff and market presence with a new website celebrating 88 years of history.

The HEIL team welcomes chemical engineer Steven George, mechanical engineer Katie Miller, and aftermarket sales assistant Rachel Holm.
