US Cryogenics, Inc. is a cryogenic system installation, repair, and maintenance company, specializing in the installation, maintenance, and repair of industrial gas systems throughout Oregon and Washington. Our firm began 20 years ago, seeking to become an industry resource for the repair and maintenance of complex, high-tech cryogenic systems. With prior experience in the industrial gas industry, US Cryogenics brought the needed expertise to support our clients with the services and products they need to keep their systems running smoothly. We provide process gas and vacuum-jacketed piping installation and repair, bulk system maintenance and repair, bulk medical gas source system installation, cryogenic trailer plumbing maintenance and repair, specialty and high purity gas system installation and repair, fill plant installation and maintenance services, bulk and microbulk tank rehabilitation and repair, and dewar repair services.

In addition, US Cryogenics operates a state-of-the-art cylinder and tank repair and maintenance facility, designed with organization and flexibility in mind. The primary focus of our tank facility is liquid cylinder or dewar repair and we are proud of our unique cylinder repair process. Our tank technicians are highly trained and skilled in diagnosing problems and issues, ensuring the work is completed accurately the first time. Our facility is capable of pulling a vacuum on up to 16 dewars at a one time, allowing our technicians to focus on quicker turnaround, so your dewars and cylinders are back in operation faster, leading to higher revenue - as you now have cylinders ready for customer use.

Our mission is to become the premier support system and partner for the cryogenic, compressed gas, and medical gas industries, providing first-class service and support to our clients in the greater Pacific Northwest Region.



US Cryogenics, Inc. was founded more than 20 years ago by Mark Hougan, with a sole purpose to fill the technical void in the repair and maintenance of sophisticated cryogenic systems – specifically solving complex gas distribution problems for large independent industrial gas suppliers. The teams of technicians for these suppliers often lacked the depth of experience necessary to solve specialized industrial gas piping and storage problems. Armed with his experience of two decades in the industrial gas industry, Mark undertook the charge of providing specialized services in the maintenance, repair, and troubleshooting of problems within cryogenic gas and liquid systems to assist customers with the storage, delivery, and use of industrial gases and liquids.

Throughout these last few decades, more businesses have placed sophisticated plasma cutters and lasers into their operations and our firm has continued to expand to meet those complex needs, whether it’s a new installation or the upgrade or repair of your current system. Our field technicians are extremely capable and skilled in handling piping and distribution problems that may crop up during the installation of a new tank and piping to the production bays.
