Common Questions Asked When We Receive a Custom CMSH Liquid Helium Dewar Request

 

When receiving a request for a liquid helium dewar, there are always some routine questions that need to be asked in order for us to manufacture the dewar to meet customer expectations. From one liquid helium dewar to another, there can be any number of differences based on how it’s going to be used.

Any liquid helium dewar can be customized based on any or all of the following specifications:

How is this container going to be used?
Is it primarily for transport/storage, liquefaction or as an experimental dewar?
If experimental, do you require a larger neck than the standard 1.5” o.d.?
Are there any dimensional restraints?
Are there pressure requirements above 10 PSI?
What country will the dewar operate in?
Will this be used for transportation by air?
Is this incorporated into a product to be sold?
What performance do you need from the dewar to meet the requirements of your application?
Base or caster mounted? Outboard casters?
Outboard bracket casters & pull handle?
For Vessels above 250 liters are fork lift provisions required?
