Deltech is a family owned small business incorporated in 1968. The late Calvin L. Stevenson, one of Deltech’s founders, is pictured. Members of the Stevenson family are part of the day-to-day operations in management, sales, engineering, and production.
Deltech has always made its home in Denver, and is today located in a new facility designed specifically to optimize our manufacturing processes. We have the space and equipment to build even the largest and most complex of high temperature resistance furnaces.

To our knowledge, Deltech is the only U.S. company manufacturing 2000°C in air furnaces.
Deltech vertical tube furnaces were used by NASA for their moon rock studies.
Deltech’s largest furnace was for the Jet Propulsion Laboratory’s F.I.R.S.T. project.
One of Deltech’s newest projects was the design and build of a custom positive pressure furnace for the National High Magnetics Laboratory at Florida State University.
We design and manufacture lab and production scale resistance heated furnace systems for materials science researchers, petrologists, and glass and other ceramic manufacturers around the world.
We work with our customers to design one-of-a-kind systems. Our competitors claim to offer custom solutions, but often those are just tweaks on their standard designs.
We offer the highest quality products featuring the best technologies. Our control systems are certified by Intertek UL 508A compliant, and we are ISO 9001:2015 certified.
Let us work with you to design and build the optimal solution for your process requirements, no matter how challenging.
Deltech Furnaces are in use around the world in government labs, corporate R&D labs, manufacturing plants, and universities. We are proud of contributing in an auxiliary way to the many exciting projects in which the engineers and scientists who approach Deltech are involved.
Deltech is a Corporate Member of the American Ceramic Society.
Deltech’s former president, Mary Stevenson, served on the Board of Trustees of the Ceramic and Glass Industry Foundation. We are pleased to contribute financial support to this organization on an ongoing basis.
Our founder and CEO, Calvin L. Stevenson, was one of the recipients of the 1998 Distinguished Alumni Awards from Montana Tech. In his honor, the Stevenson family established the Calvin L. Stevenson Endowed Scholarship to the Dept of Metallurgical and Materials Engineering at Tech.
Deltech has donated furnaces to Montana Tech, Missouri S&T at Rolla, and the Universidad de la Republica in Uruguay.
