Why Choose One Cryogenic Transfer Hose Over Another?

Hoses are one of the unsung heroes of cryogenics. They aren’t directly responsible for the production or storage of cryogenic liquids, nor do they make headlines in the same way that innovations enabled by cryogenics do. However, hoses are found throughout cryogenic processes and in many products like MRI machines...

Cryomech Restructures, Introduces Improved Cooler during Pandemic

While 2020’s pandemic altered “business as usual” for nearly every organization, operation and individual around the globe, some businesses took advantage of the necessary changes to reflect on their operations and expectations. Late last year, Cryomech (CSA CSM) took the opportunity and restructured internally. Now, the new—and growing—team has introduced...

Jefferson Lab Sets Date for 2022 Open House Event

The Department of Energy’s Thomas Jefferson National Accelerator Facility (Jefferson Lab, CSA CSM) will open its doors to the public for its next Open House event on March 26, 2022. The free event will offer an opportunity for people of all ages to explore Jefferson Lab’s world-class research facility, including...

A Breakthrough For Electric and Hydrogen-powered Aircraft

A major breakthrough in electric propulsion for long-range aircraft could soon be on the horizon. The presence of a cold source, in the form of liquid hydrogen, alongside superconducting technologies promises to unlock new possibilities. The ASCEND demonstrator project by Airbus UpNext aims to mature these technologies to significantly boost...

NASA SLS Green Run Testing Complete, Boeing Readies Core Stage for Tow to Florida

NASA’s Space Launch System (SLS) program and prime Core Stage contractor Boeing wrapped up the Green Run testing campaign on the Artemis 1 flight article at the Stennis Space Center and are readying the vehicle for its long-awaited shipment to the Kennedy Space Center in Florida. After reviewing the performance...

SpaceX Conducts Cryogenic Test on Starship SN15

On April 13, Starship SN15 went through the cryogenic proof test. The cryo-test ensures if a spaceship is able to withstand in-flight atmospheric pressures and extremely low temperatures. This is achieved by simulating the in-flight conditions by filling the Starship with liquid nitrogen that has a temperature of −196 °C...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

Looking for process to freeze large volumes of plastics and rubber

I’m looking for a process to freeze large volumes of plastics and rubber prior to submitting this mass of material to a grinding process that reduces it to a powder. Any thoughts? Any known processes which I can visit? Any known technologies? Can you refer me to other resources for...

Sealant Adhesive KAE 89?

Can you give me contact details for the manufacturer of a “sealant Adhesive” KAE 89? It is a vapor stop, used on insulation covering LNG carrying conduits. This is a suggested alternative to Foster 90-66. Do you have details of any other alternative products for this application?

Data for thermal conductivity for phenoloc high pressure laminate NEMA CE grade

Can you provide data or information on how to obtain data for thermal conductivity for phenolic high pressure laminate NEMA CE grade, at low temperatures (4 Kelvin to 100 Kelvin)?

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.
