Thermal Dynamix (a Judd Service company) designs, engineers and fabricates industrial furnaces and atmosphere generators for heat treating processes.


We can design and build a system specifically to fit your needs or we can fabricate from your proprietary design.  

We also sell a variety of molybdenum parts and nickel catalysts and supports to meet all of your needs.



Thermal Dynamix has over 90 years of experience in designing and building processing systems for the heat treating industry. We fabricate from materials such as stainless steel, molybdenum and tungsten. We have the ability to design and fabricate specialized large equipment such as ammonia dissociators, endothermic and exothermic gas generators, industrial ovens and furnaces, and high temperature kilns. We take pride in providing products with efficient operation, durability and ease of maintenance. 

Thermal Dynamix acquired Rolock Inc. in July of 2001 and upheld the quality standards that made Rolock a benchmark for the industry since 1928. Rolock’s product line included industrial furnaces, ovens, muffles, retorts, thermocouples and temperature sensing devices. In the 1950’s, Rolock began manufacture of atmosphere generators and ammonia dissociators; continuing to build the simplest, most durable, and reliable generators available anywhere. With the acquisition of Rolock, we continue to maintain all original manuals, blueprints, drawings, patents and documentation for these original products. 


Please read our Terms of Service. They are simple and straight forward; we don’t use small print. Note that length of warranty varies for parts and systems. We look forward to your inquiry!
