OPW Acquires Demaco in Cryogenics Consolidation

OPW announced today that it has completed the acquisition of Demaco, a provider of vacuum jacketed piping and other cryogenic equipment for gas producers, research institutions, EPC contractors, and end-users of liquefied gasses within various end-markets. Demaco will become part of the OPW Clean Energy Solutions business unit. Established in...

Into the Fast Lane for Quantum Innovation

The nascent quantum technology supply chain has reached an inflection point as companies large and small – among them household names like Google, Microsoft and IBM as well as a new wave of ambitious start-up ventures – shift gears to translate their applied research endeavours into at-scale commercial opportunities in...

Viewing Fast Vortex Motion in a Superconductor

S. Nakamura et al. [1] Peering into the vortex. Top: Vortices form in a superconducting film (gray) in the presence of an external magnetic field provided by a coil. The field generates a shielding current in the film (pink). An infrared pulse transmitted through the superconducting film provides information about the vortices’...

KLM Partners With ZeroAvia For Liquid Hydrogen-Powered Demo Flight

KLM Royal Dutch Airlines has agreed to perform a flight demonstration of ZeroAvia’s ZA2000 hydrogen-electric engines in 2026. “We’re going to do a groundbreaking demonstration flight between two airports using liquid hydrogen fuel,” KLM CityHopper MD Maarten Koopmans says at the Farnborough Airshow. “KLM wants to be a front-runner in this field, and taking...

BHEX Leverages Cryogenics to Capture Black Holes

Introduction to BHEX-The Black Hole Explorer (BHEX) is a mission that will discover and measure a black hole’s photon ring, capturing light that has orbited a black hole. BHEX will extend the Event Horizon Telescope (EHT) into space, producing the sharpest images in the history of astronomy, whilst operating a...

Looking Backward and Forward

Since 2018 I have been writing this column on pioneers in cryogenics. So far, a total of 30 people have been profiled. With this column taking a slightly different direction in the future (more below), it’s worth asking if these pioneers had anything in common. Here are a few common...

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 manufacturers of cryogenic dewars with infrared detectors (long wave)

We are looking for manufacturers of cryogenic dewars with infrared detectors (long wave). We need these dewars for repairing infrared systems (thermographic systems) and we cannot find such glass dewars. Do you know any manufacturers’ addresses?

Manufacturers of cryogenic regenerator lead spheres?

Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.

Assistance with resolving a sealing problem?

We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...

Cryogenic data on leather and nomex

Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
