K508 Integral Stirling 1/2W Micro Cooler

The K508 microcooler design model is solidly based on the concepts of direct detector mounting on the cooler’s cold finger, and the integral construction of the cooler and Dewar envelope. Operation of the integral Stirling microcooler, driven by a DC brushless motor, is clean, silent and highly reliable. Model K508 has been in service since 1994.

Over 60,000 coolers have been fielded and operate reliably onboard numerous ground, airborne, heliborne, naval and space applications. The K508 contains an onboard temperature controller, which offers standby, remote shutdown and over-temperature / over-current protection options. By adopting various types of Dewar envelopes, this microcooler can meet the cooling demands of most advanced IR detectors.
