Dover announced that it has acquired Cryogenic Machinery Corp. (“Cryo-Mach”). The acquisition will become part of the PSG business within Dover’s Pumps & Process Solutions segment, expanding Dover’s presence in the cryogenic end market. Headquartered in North Hollywood, California, Cryo-Mach is a specialized designer and manufacturer of mission-critical cryogenic centrifugal pumps,...

Cryogenic Upgrade Boosts Capacity by Almost 80%

With the rise in deep-space missions, more international requests, and increasingly intense data streams, the demand for deep-space ground stations has never been higher. Yet, the system is nearing full capacity. To alleviate the load on its three deep-space antennas within the global ground station network (Estrack), the European Space...

Advancing Hydrogen Innovation Through Collaboration and Breakthroughs

Over 150 research and industry experts gathered in London for a Cryogenic Hydrogen Research Conference delivered by the ATI’s Hydrogen Capability Network (HCN) in partnership with the Civil Aviation Authority this week. This inaugural HCN conference with a cryogenics focus brought together academics, students, and industry engineers working in the field...

New Superconductive Materials Have Just Been Discovered

In 2024, superconductivity—the flow of electric current with zero resistance—was discovered in three distinct materials. Two instances stretched the textbook understanding of the phenomenon, while the third defied it entirely. “It’s an extremely unusual form of superconductivity that a lot of people would have said is not possible,” said Ashvin...

Mixed Refrigerant Cycles

Most cryogenic refrigeration systems, both large scale systems and cryocoolers, use helium as a working fluid. There are a number of advantages to helium, not the least of which is that helium remains a fluid down to the lowest achievable temperatures. In order to freeze helium, pressures of over 20...

Fountain Pumps and He II Phase Separators

Helium II (He II), the second liquid phase of the 4He isotope described in this column in Cold Facts Spring 2010 (http://2csa.us/he2), can be modeled as consisting of two interpenetrating fluids. One, the superfluid component, has zero viscosity and entropy and the other, the normal fluid component, has nonzero viscosity...

Turboexpanders

A vital technology in the refrigerators and liquefiers described in Cold Facts Volume 31 Number 3 is that of turboexpanders. These devices are rotating machines in which the process fluid (e.g., helium) does work against the turboexpander while moving from high pressure to a lower pressure and thus is cooled....

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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...
