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.
A simple idea with a big impact
As cryogenic applications grew, so did the need for more bulk tanks and transports, as well as a more efficient process to build them up and get them into service faster. Recognising the need, some engineers sketched out an idea on a cocktail napkin to combine all of the needed components into a “mainfill assembly” that would speed up the process without compromising on quality or performance. By reducing the man hours, tanks would go out the door faster and more frequently.
Not only did this speed up the tank build time, it also ensured that tanks were fitted with the proper components to maintain the right pressure-to-liquid balance during cryogenic fill applications. Ratermann’s mainfill assemblies currently include the most common components (top and bottom fill valves, drain valves, check valves and strainers) but do offer a variety of configurations based on application needs.
