CG Thermal Leadership
Richard Chandler, President
After commissioned service in the US Army and an MBA degree, Chandler began his career in industry in 1974 with the Graphite Products Division of Carborundum Company. Shortly afterward, this was renamed the Metaullics Systems Division, with Chandler as General Manager. One of the major products produced by this Division was graphite heat exchangers of all major types including shell and tube, cross-bored block and cubic heat exchangers. Also, this Division was responsible for designing and introducing to the chemical process industry the revolutionary SiC-tubed heat exchanger now sold by CG Thermal under the Umax® name. In 1993, the Division was spun off from Carborundum Company, and acquired by a group of investors including Chandler. The heat exchanger business achieved unprecedented growth and success under this group, including establishment of a plant in China to serve that fast-growing market. The business was acquired by Carbone Lorraine in 1998.
In 2010, Chandler led a group of key past employees of the Metaullics Systems Division to re-constitute this business, and bring to the CPE the same commitment to design excellence, quality and customer care that led to the division’s previous success. Product offerings of the new company, CG Thermal LLC, include a complete line of graphite and ceramic heat exchangers and fluoropolymer lined components.
Greg Becherer, VP Sales and Marketing
Greg began his career as an Application Engineer with BW Rogers Co., a distributor of many lines of equipment for the CPE. He then moved The Carborundum Company in 1987, where he learned the application and design of graphite heat exchangers from the bottom up. After the Division was sold to Carbone, Greg took on the job of Sr. VP, Sales and Marketing of the AstroCosmos Division, becoming an expert in the applications of reactive metal heat exchangers and process equipment, in addition to graphite and ceramics.
Greg has been involved in almost every aspect of the graphite and ceramic corrosion resistant heat exchanger market, including design and application engineering, development of advanced design heat exchangers, and the full range of sales, marketing, and international business development activities. With his extensive CPE experience, and a B.S. Degree in Mechanical Engineering, Greg is a recognized expert in corrosive heat transfer applications.
Greg is a principal and charter member of CG Thermal LLC, and brings his considerable technical expertise and knowledge of the needs of the CPE to our customers.
B. David Hudson, Principal and Charter Member
After receiving his B.S.M.E. and M.B.A. degrees, David began his career with the Pfaudler Company, where he had complete engineering responsibility for thermal and mechanical design of their glass and alloy heat exchangers, for a period of 20 years. Then, after the Metaullics Heat Exchanger Division (then owned by BP America) was merged with Pfaudler, David took on additional responsibility for the design and sizing of graphite heat exchangers.
In 1987, David joined the Metaullics Systems Company as Engineering Manager for the Heat Exchanger Group. In that position, he was instrumental in the design of the award winning Hexoloy® ceramic heat exchanger, which continues at CG Thermal under the Umax® trade name. In total, David has almost 40 years of experience in mechanical design and thermal sizing of corrosion resistant heat exchangers for the CPE.
He is a principal and charter member of CG Thermal LLC.
Joan Bova, National Technical Sales Director

Aaron is the acting Chairperson for the ASME Sub-Group of Graphite Pressure Equipment where he has been a member since 2010. He is also a member of the ASME Section VIII main committee and part of NBIC Subgroup graphite working group. His working knowledge of code design rules, extensive hands-on design experience, and practical approach brings high value to all of our projects.
Caleb Krichbaum, Quality Manager
Caleb received his BSME from the University of Akron in 2017. While attending school, he worked three co-op rotations for Babcock & Wilcox. While there, he helped research the viability of solar boiler systems, and the prevention of corrosion in boiler systems. After graduation, he joined CG Thermal’s team as a quality and project engineer.
At CG Thermal, he works with production and sales to guarantee our customers receive the quality products they need. Since becoming a part of CG Thermal, he has implemented in-house testing improvements to create a more efficient shop floor, as well as improve the products delivered to our customers.
