Insulated Vessels





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 of insulation.

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.
