When it comes to their cryogenic vessels,
everyone has different insulation needs. With more than 60 years experience,
Prentex knows what type of insulation will work best for you. Whether your
vessel relies just on vacuum insulation or opts for 'super' insulation, you
can be sure that Prentex’s recommendations are optimal for your unique cryogenic needs.
A high vacuum cryogenic vessel will automatically have a form of insulation
as the vacuum between the inner shell tank and outer jacket of the vessel prevents the transfer
of heat. However, this system is not always practical, especially if you’re looking for
short-term storage or transfer vessels. Many people often prefer a non-vacuum form of insulation
as it is more cost-effective as well as simpler to apply. Even if your cryogenic vessel does
have vacuum insulation, you may still want to take the extra step of having a secondary form
Because cryogenic tanks are designed to keep their contents at extremely
low temperatures, it is vital that precautions are taken to maintain these temperatures.
If the outer shell of your cryogenic vessel were to be punctured, the vacuum pressure would
rapidly dissipate, while letting in outside air. Contact with this air would quickly heat up
the contents of your tank, which can pose a safety hazard. However, extra insulation will
decrease the amount of heat that your tank comes into contact with. As a result, there is
a much slower build up of pressure within the tank while venting can be done gradually, helping
to reduce any threat to safety.
A variety of materials can be used to effectively insulate your cryogenic
vessels. Perlite, foam, fiberglass batting, glass, lampblack, silica aerogel, composite coatings
and even wood are just some of the many forms of efficient insulation available. As custom manufacturers
of cryogenic vessels, Prentex can build the tank with the insulation that best suits your tank.
