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...

Jefferson Lab Dedicates Niobium-Tin Particle Accelerator Prototype

More than 30 of the world’s most advanced particle accelerators rely on one technology: superconducting radio-frequency (SRF). This technology, typically powered by pure niobium metal, has seen recent advancements with the introduction of niobium-tin alloys, which promise greater efficiency. The US Department of Energy’s (DOE) Thomas Jefferson National Accelerator Facility...

Vacuum Barrier Corporation Enhances Customer Support Through Field Service Evolution

Vacuum Barrier Corporation (VBC) has long been recognized for its commitment to excellence in cryogenic systems and liquid nitrogen (LN2) solutions. Recently, the company has made significant strides in bolstering its customer support by establishing a dedicated department for reliability and technical support. Dana Muse, Reliability and Technical Support Manager,...

Argonne Empowers Female Energy Leaders

Argonne National Laboratory (CSA CSM) recently hosted 12 women leaders from Net Zero World partner countries for a two-week training program under the Climate Smart Women Energy Leaders (CSWEL) initiative. In collaboration with the U.S. Department of Energy’s (DOE) Net Zero World Initiative, the program aimed to equip participants with...

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...

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

Air Separation and Liquefaction

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 to purchase new LN2 freezer: any suggestions?

I will be purchasing a new liquid nitrogen freezer soon, but I am limited by space restrictions. The freezer cannot be more than 38 inches wide. However, it would be beneficial if the freezer holds a high number of racks such as 24. In addition, we prefer not to purchase...

Affordable flow meter to measure LN2 flow through a pipeline

I am trying to find out if anyone knows of or has used an affordable flow meter that can measure liquid nitrogen flow through a pipeline. It doesn’t need to be very accurate as it’s really to allow people in different departments to allocate cost rather than for scientific measurement....
