Ratermann is excited to announce two new sizes of the Arctic Fox microbulk tanks: 7500L and 8100L! The new sizes round out our full Arctic Fox mini and microbulk offering from 1500L to 8100L, covering a wide range of needs and applications.

Every component of a bulk tank is important for its operation, but from a safety standpoint, the single most important part is the diverter assembly. Why? It holds the main ASME pressure relief valves that are crucial for safe tank operation and preventing catastrophic failures. Every tank that Ratermann sells has a Herose diverter assembly included.

In the early days of cryogenic bulk tanks, fitting a tank with valves and instrumentation was a lot more complicated and involved, as customer needs grew to include check valves, strainers, relief valves, and drain valves in addition to the primary top and bottom fill components. It took hours of welding and brazing to build up a tank, which greatly limited how many tanks could be outfitted and put into operation.

Copper tubing is a popular material in cryogenics because of its ductile nature at low temperatures. But copper is not immune to pinholes and cracking due to daily wear-and-tear and weaknesses introduced by contaminants and general exposure to the elements.

Tube fittings probably aren’t something you think about every day, at least, not until something breaks. And when that something breaks, you want to be certain you have the replacements on-hand that can do the job.

The term “ASME Certified” gets thrown around a lot in the cryogenic and compressed gas industry. But what does that really mean and why is it important?
