How does a Stirling freezer work?

Stirling technology uses environmentally safe helium as its refrigerant. The two moving parts, the piston and the displacer, expand and compress helium in the engine, absorbing heat from the thermosiphon, keeping the cabinet cold. They don’t wear out because the inert gas bearings eliminate internal friction.

Who makes Stirling Ultracold?

Global Cooling Inc.
To increase production, Stirling Ultracold—a division of Global Cooling Inc. —contracted with a Kentucky company in late 2017 to build additional units. The company sells three models: the upright, the shuttle and the undercounter.

What is ultracold freezer?

The Stirling Ultracold SU780XLE is a reliable and energy-efficient upright ultra-low temperature (ULT) freezer. These scientific freezers are designed for the widest temperature range and precise temperature control. of your freezer space and ensure the most item storage for samples in your cold chain.

Where is Stirling Ultracold?

Stirling Ultracold, a division of Global Cooling, Inc., manufactures and sells environmentally sustainable ultra-low temperature (ULT) freezers for the global market from its headquarters in Athens, Ohio.

What is Stirling refrigeration?

The Stirling cycle is a closed cycle, which means that the cryogenerator working gas (which is Helium gas) never comes into contact with the substance (gas or liquid) being cooled. This also eliminates contamination of the working gas, which results in greater operational safety.

Where are Stirling freezers made?

Athens, Ohio
Starting from a base in Athens, Ohio, our goal is no less than becoming the #1 ultra-low freezer manufacturer in the world. It’s from here that Stirling Ultracold products make it possible to find cures for diseases and sustain our environment, all at the same time.

What is a super freezer?

At a consistent low temperature of -76 °F, super freezers operate differently than regular freezers. While ingredients freeze gradually in the conventional freezer, super freezers freeze ingredients quickly and evenly, so they are as fresh as the moment before your froze them.

Are Stirling engines used today?

Stirling engines are energy conversion devices that may be used as prime movers, refrigerating engines or heat pumps. Currently they are used commercially as cryogenic cooling systems and are under development as low noise, low emission automotive engines.

What is a Stirling ultracold freezer?

Stirling Ultracold offers ultra-low freezers with high-density item storage capacity, all of which operate on the free-piston Stirling engine. All freezers are available from Stirling Ultracold and from leading laboratory supply distributors and dealers worldwide.

Which Stirling ultracold is right for You?

The Stirling Ultracold SU105UE undercounter ultra-low temperature (ULT) freezer is ideal for bench-side personal storage or for use in areas where larger-volume ULTs are not suitable. The Stirling Ultracold SU780XLE is a reliable and energy-efficient upright ultra-low temperature (ULT) freezer.

What makes the Stirling su780xle different?

The innovative Stirling engine creates a variety of benefits you won’t find with a compressor-based ULT, including: Other ULTs require you to maintain a setpoint within a -50°C to -80°C temperature range. The SU780XLE can maintain temperature setpoints anywhere within a much wider -20°C to -86°C ultra-low temperature range.

How does the Stirling engine work?

The stirling engine’s continuous modulation and fully adaptive capabilities eliminate the on-off cycling operation of compressor-based systems. This delivers uncompromising cooling performance and reliability with unmatched energy efficiency.
