It is with great regret that we mention the very recent passing of Mr. Keith Grier of ProTech Thermal Services at the age of 78. Keith’s entire life revolved around the heat treating industry, both from his time as a founder of GM Enterprises, a vacuum furnace manufacturer which is now part of Nitrex and with ProTech Thermal Services which also offers new vacuum furnaces and solutions for thermal processing companies. Both companies are located in California and Keith was still involved with Protech in Sales and Customer Service. Keith was a good man who will be missed. When more details are available we will share them.
