BS&B Safety Systems Accelerates Service to OEMs

OEMs in virtually every market, from aerospace and automotive to refrigeration and fire protection, rely on rupture disk devices for pressure relief and pressure release of gases and liquids. The challenge of time faces all product designers; how do we get a custom solution in an acceptable timeframe? Now, at least...

The Cryomech PT205: A Compact Cryocooler with a Wide Range of Applications

In today’s rapidly evolving technological landscape, the demand for efficient and compact cryocoolers is more critical than ever. A wide range of applications increasingly require high performance cooling systems that can seamlessly integrate into limited spaces. Smaller cryocoolers prove invaluable in these contexts, offering the precision and reliability necessary to...

CO2Meter’s Critical Gas Safety Solution

CO2Meter has long been recognized for its remote oxygen depletion safety alarm, which warns staff before they enter areas with dangerously low oxygen levels caused by pressurized gas leaks. Pressurizing a gas in a tank or cylinder provides a convenient way to transport and store it. Flower shops use helium cylinders...

Continuous Cryogenic Pellet Injection System Developed for Tokamak Fueling

A continuous cryogenic pellet injection system for tokamak fueling has been developed by a joint research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences. It overcame technical challenges related to cryogenic ice formation, pellet cutting and pellet launching. Cryogenic pellet injection is a cutting-edge technique...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
