DE-215 Cryocooler Series
The DE-215 is our largest and most powerful closed cycle cryocooler. This system is ideal when there are high heat loads and when fast cooldowns need to occur.
ARS manufactures both the cryocooler and the laboratory interface allowing for seamless trouble-free integration of our laboratory systems.
Our DE-215 cryocoolers are typically equipped with a bolt-on stainless steel instrumentation skirt with an ISO-160 flange (DE-215*E).
The DE-215*B is just the bare cold head geared towards OEMs and system builders who prefer to build their own custom laboratory interface.
The ARS manufactured DE-215*B is a true UHV cold head (10-11 Torr) where all of the rubber o-ring seals have been replaced with welded joints and metal seals.

The ARS Advantage
The DE-215 cold head is a precision machine carefully tuned to achieve temperatures below 4 K with 1.5 W of cooling power at 4.2 K.
The DE-215 cold head is a rugged workhorse built with power and durability in mind achieving temperatures below 9 K with 9 W of cooling power at 10 K.
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.
The water cooled ARS-10HW compressor that powers the DE-215 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.
