K527 Low Power Split Stirling Linear Micro-Miniature Cryocooler

Model K527 is a new member of RICOR’s expanding family of cryogenic coolers. This model is the smallest and lightest in the range of linear split Stirling cryogenic cooler having nominal heat lift 1/2W @95K @71ºC and MTTF well in excess of 30,000 hours.

The K527 is an ultimate solution for demanding infrared applications, where weight, size, power consumption, heat sinking, reliability, flexibility in system design, vibration export and aural stealth are of concern. The cooler comply fully with MIL-STD-810 meeting the stringent environmental requirements for mission-critical applications.

A K527 derivative based on short cold finger (named “Shorty”), designed for novel IR detectors operating at 150K and above for compact payloads requiring exceptionally fast cooldown times.
