From Zero to Cryo in 5 Days

Our company first began in 1982 as “Cryoco, Inc.” by providing cryogenic engineering classes at the American Institute of Chemical Engineers (AIChE) conferences in Los Angeles, California. 

Dr. Thomas M. Flynn founded our cryogenic consulting firm 45 years ago. Flynn had worked for the National Bureau of Standards in Boulder as a cryogenic engineer for 28 years then later went on to work for Ball Aerospace. A former president of the National Cryogenic Engineering Association, he is the author of more than 50 professional publications on topics related to cryogenic engineering. Flynn first developed a cryogenic engineering short course and a cryogenic safety course then later authored the Cryogenic Engineering Handbook, first and second editions (which course participants receive). He was also a Professor Adjunct at CU, Boulder and taught at the Colorado school of Mines, and the UCLA Extension. Flynn was regarded as one of the world’s foremost experts on cryogenic engineering; he passed away in 2015.

David-John Roth worked, taught, and travelled worldwide with Dr. Flynn for 28 years. They developed our company’s first cryogenics courses. Mr. Roth began solely teaching the courses when Flynn could no longer do so until 2008.  Dr. Flynn became disabled and left the entity CRYOCO Inc. to David-John Roth. Mr. Roth continued to respond to requests for cryogenics courses from 2009 to 2011.
 

In 2012, Roth re-incorporated the company under his own management as “CRYOCO LLC.” The courses were wholly re-written to a full engineering and design venue. This will be his 45th year presenting the courses to NASA, U.S. Government agencies, and all types of commercial industry and aerospace companies all over the world. Roth has expanded and revised all of the course material to reflect current standards and technology.  

CRYOCO brings more than a century of experience and innovation across all sectors of thermal management. We are proud and excited to continue providing these unique courses nationwide.

David-John Roth has owned and run CRYOCO LLC as sole managing entity for 11 years. He works at The Kennedy Space Center (KSC) in Florida as a Subject Matter Expert in Cryogencis and Mechanical Engineer, Level VI. He is available upon request throughout the year for on-site cryogenic courses.
 

Serving on the Space Launch System Project at KSC as an employee of Jacobs COMET in the Fluids and Propellants Division, Mr. Roth's work encompasses: the design of cryogenic systems and components, creation of technical drawings, review of drawings, component and assembly drawings, identification, selection and specification of cryogenic valves and components, manufacturers bids and reviews for technical merit, and selects the manufacturers for those projects. Roth also acts as the technical representative from inception to completion of those engineering projects in all technical oversight, installation, verification & testing, and administrative aspects. 

Roth performs cryogenic fluid design as well, including oxygen compatibility analysis and other technical assessments. He works on testing and installation of these systems at KSC and other NASA, Department of Defense and commercial launch systems and space programs. 
 

His current projects include: ML1-Artemis I, ML2 - Artemis  II, the entire KSC LH2 and LO2 propellant ground system, the Launch Equipment Test Facility, and other technical duties such as Pressure Systems Verification and compliance. 

His former employers include: Cryoco Inc, Ball Aerospace, Redstone Aerospace, Stinger-Ghafarrian Technologies, Kellogg-Brown and Root. 

In his spare time, David-John enjoys traveling, scuba diving, kayaking, outdoor sports, and afternoons spent at the gym.
