DE-110 Single Stage Closed Cycle Cryocooler

The ARS manufactured 100 series Single Stage Cryocoolers reach temperatures below 25K and are tuned for maximum cooling power in the 77-150K range. These cryocoolers are ideal for large stage cooling or fast cooldown applications.

The DE-102 is our lightest, lowest cost single stage cryocooler, suited for small projects requiring fast cooldown.

The DE-104 is our intermediate single stage cryocooler, well rounded in speed and cooling power. When upgraded with our turbo option the DE-104T has an impressive 60 W of 77K cooling power.

The DE-110 is our largest, highest cooling power single stage cryocooler. Topping out at 310 W at 150K, this is the best choice for very large stage or high heat load applications.

The 100 series cryocoolers are typically just the bare cold heads (DE-102F, DE-104F, DE-110F) geared towards OEMs and system builders who prefer to build their own custom laboratory interface.

However, because ARS manufactures both the cryocooler and the laboratory interface we can customize all of our single stage cryocoolers to allow for seamless, trouble-free integration with our laboratory interfaces.

The ARS Advantage

High Temperature Options
800K Interface Manufactured by ARS

Our high temperature interfaces use a unique combination of mechanical and thermodynamic properties to create a high temperature thermal disconnect between the cold head and the sample space. This allows for heating of the sample space far in excess of the maximum 355 K temperature of our cryocoolers.

450 K The Easy Way

Our 450 K interface is a simple semi-permanent addition to the cold tip that expands the upper sample temperature range by 95 K utilizing most of the same instrumentation as our standard cryocoolers.

800 K - Pouring on the Heat

Our specially designed 800 K interface goes beyond the standard techniques to provide a unique system that maximizes thermal conduction at low temperatures while minimizing heat transfer at high temperatures. Beyond the safe operating temperature of silicon diodes, the standard sensors are replaced with E-type thermocouples and platinum RTDs.

Water Cooled Compressor For Your Convenience
The ARS-2HW Compressor

The water cooled ARS-2HW, ARS-4HW, ARS-10HW compressor that powers the DE-102, DE-104, DE-110 Series cold heads has many benefits that are amplified in small laboratory settings. The water cooling redirects heat energy that would otherwise be dumped into the lab by a large cooling fan. The lack of a large cooling fan also dramatically reduces the noise of these compressors (only 60 dBA). Additionaly with minimum air circulation, the air currents and dust are kept to a minimum. The high efficiency heat exchanger results in low water usage and saves space inside the compressor, giving it a small footprint. When water is not available our Coolpac™ remote recirculation system can send cooling water from up to 100 feet away.

Easy Do-It-Yourself Maintenance
DE-202 Disassembled for Service

The ARS DE-102, DE-104, DE-110 Closed Cycle Cryocooler operates on a pneumatically driven Gifford-McMahon refrigeration cycle that is both mechanically simple and robust.

12,000-Hour Maintenance Cycle

Over time the internal components of the cold head begin to wear. Eventually the performance of the cold head will decline and some time after 12,000 hours certain internal components need to be replaced or refurbished. With most closed cycle cryocoolers the only option is to send the cold head back to the manufacturer for service.

A Second Option

The simplicity of the ARS pneumatically driven cryocooler allows for another option. Our customers can purchase a service kit for our 10 K and 5.5 K cryocoolers that replaces all of the worn components. This service kit can be ordered ahead of time and reduce down time to a matter of hours instead of weeks.
