Cryogenic Products

Efficient & Effective Storage Systems: Cryobiology applications
require the most thermally efficient storage systems. Praxair
and Chart’s combined years of cryogenic experience provide
the added assurance your system will be designed and installed
to suit the application. From engineering and layout to system
installation and startup, Praxair can provide a single point of
contact.
Security for Samples: The success for any liquid system starts
at the point of use, or the application and works its way back
to the cryogenic liquid storage. The Praxair and Chart team
of engineers will conduct a total site survey to make sure all
situations are considered for sample security. The Chart freezers
offer full function alarm systems for low and high liquid level,
high and low temperature for each of the 2RTD probes, LN2
supply, valve failure and power failure. Additional controller
options allow for battery back-up systems for protection against
electrical supply interruptions. The hot gas bypass system vents
incoming gas until the liquid reaches the valve, minimizing the
normal losses associated with filling from liquid containers.
The properly designed vacuum jacketed piping system minimizes
the infiltration of heat into the system as a whole, which reduces
operating costs. Chart vacuum insulated piping is the result
of 30 years of continuous design and build improvement in
the pursuit of manufacturing experience. The inner pipe in the
system utilizes the same multi-layer component super insulation
which gives our cryogenic tanks world leading performance. Chart also pioneered bayonet type connections throughout Cryo-Bio
applications, giving tight seals and higher performance with low LN2 usage. The T304 stainless inner-internal bellows vacuum pipe
we offer is an industrial/commercial grade build to the same rigid requirements as ASME piping. Internal bellows eliminate contraction
of the outer jacket, meaning no convoluted hosing is required.
Cost: We recognize that managing costs have required companies to improve operating efficiencies. A “cost of ownership (COO)”
analysis is the best way to understand the impact of your purchasing decisions. Praxair can provide various COO models to help you
evaluate the best gas, equipment and system decisions for your facility.
Examples include:
• Analyzing your current and future liquid and gas volume requirements will determine the most cost effective mode(s) of supply,
dewars, microbulk, bulk tank, membrane or high pressure cylinders.
• Facility layout and logistics will impact piping system decisions.
• Mechanical freezers (energy, maintenance, life) vs. cryogenic storage.
At your request Praxair can work directly with architectural or consulting engineers for large expansions and new construction.
Gas-handling equipment and delivery systems can be purchased directly from Praxair, eliminating extra costs typically associated
with contractor purchases. System design services are available from the simplest to the most complex projects in addition to full
turn-key packages.
The rewards of bringing innovative technologies to your facility can be tremendous. The Praxair/Chart team is ready to show you what
it means to have a uniquely capable, enthusiastic, and resourceful supplier working on your behalf.
