Hi Adam,
You should try reaching out to your industrial gas supplier. It may be L'Air Liquide/Airgas, Linde, Praxair or another company, but they should offer technical solutions for you as part of their services. (I was an engineer at one for many years providing such systems.)
Best of luck,
Lisa Maxwell
