Company Profile

The History of Thermal Technology


RD Brew Founded

Brew, an early pioneer in the development of high temperature vacuum furnaces was founded in Concord, NH.


Astro Industries Founded

Known as “The Furnace People”, Astro Industries was an early innovator of high temperature furnaces and services founded in Santa Barbara, CA.


RD Brew Patents “BreWeave™” Heating Element Design

At the direction of RD Brew a collaborative effort by Brew engineers, led by Fred Andersen a highly skilled engineer, develops a new tungsten heating element design which outperforms the standard mesh design developed earlier. This new design allowed the heating element to better maintain its shape and heating repeatability at temperatures of up to 3000˚C. 


Astro Industries an early pioneer in the fiber optic cable industry

Astro industries designs and starts manufacturing Fiber Optic Draw furnace systems to supply the increasing development of connecting both phone and computer systems by Fiber Optic Cables


Thermal Technology was Created

RD Brew Company and Astro Industries merge to create Thermal Technology


Thermal Technology moves to Santa Rosa, California

Astro Industries which was now Thermal Technology moves operations to a brand new larger custom built facility in Northern California. Thermal Technology later consolidated all operations to this location by moving Thermal Technology (Formerly RD Brew) to this location in 2003.


Thermal Technology First USA Manufacturer of SPS

Seeing the need for new technologies for faster processing of the ever increasing line of new materials Thermal Technology becomes the first USA manufacturer of SPS, DCS, FAST technology.


Thermal Technology Expands Operations for the industrial Sapphire Industry

Seeing a quickly growing need in the industrial sapphire industry Thermal Technology expands operations to supply Kyropolous Crystal Growers to the market making some of the largest and best quality sapphire boules available. In tandem Thermal Technology becomes the only USA manufacturer of EFG Sapphire Crystal Growth technology.


Thermal Technology Designs and Supplies the largest DCS (SPS, FAST) in the industry

Thermal Technology, still the only US manufacturer of DCS technology, does another first by designing the largest and most advanced DCS available worldwide. This new system with unmatched technology is the result of years of continuous testing and development conducted at our in-house R&D facility. This NEW to the market DCS 800 boasts 800 Tons of Force and 150,000 Amps of power.
