-86℃ 스털링초저온 냉동고

환경친화적이며 우주시대의 냉각기술 분야의 진화에서 혁신으로...

1816년에 발명되어 스털링 초저온 냉동고에 적용한 스털링엔진은 냉동고에 적용되는 최고의 효율과 환경친화적인 냉각기술의 해법으로 계속 진화를 해 왔으며,

미국에서 100% 천연냉매(헬륨, 에탄가스)를 사용하는 유일한 냉동시스템입니다.

스털링엔진은 NASA의 우주왕복선에 사용되어 왔으며, RHESSI 우주선의 장비들을 냉각하는데 사용됩니다.

The Industry's Best Performance

Lowest Energy Consumption, <6.86kWh/day at -75℃
 Fastest initial Pull-Down, Ambient to -80℃, <6.5 hours
 Fastest Door Opening Temperature Recovery, <1.5 hours to -80℃
 Slowest Warm-Up Time, 2.5 hours from -80℃ to -60℃


The benefits of Stirling Ultracold freezers reach all levels of the institution from the laboratory to the boardroom

  • Lower operating and maintenance costs save money and help meet sustainability objectives.
  • No refrigeration compressors, zero oil.
  • 100% natural refrigerants.
  • Reduced energy consumption versus the competition, more than Max. 75% in some cases.
  • Reduced heat output by 50%, less load on HVAC system.
  • Minimal current surge on re-start, less electrical infrastructure and back=up power required.
