The HFPTC is a high-frequency Pulse-Tube based on our expertise in cryogenic cooler design for the space industry. Our engineering teams have developed a cooler with reduced dimensions and high performance. The HFPTC combines a Thalès Cryogenics B.V compressor with a cold finger developed by Absolut System.
Spatial: This cooler, designed for Earth observation missions, is particularly well-suited to the task thanks to its compact size. In particular, it eliminates the need for complex “passive radiator cooling” architectures.
The HFPTC is a compact cooler that can be used in terrestrial imaging to cool infrared detectors, particularly for civil and military security cameras, and for surveillance of strategic areas.
The result of a collaboration between Absolut System and Thalès Cryogenics B.V., the Pulse-Tube LPT6510 combines the MPTC compressor and the SSC80 pulsed gas tube developed by Absolut System.
The LPT6510 offers excellent efficiency for 60-150K applications, proven reliability and reduced levels of exported vibration. Recent developments have enabled the Pulse-Tube to be upgraded to an “all-welded” design, increasing robustness and reliability by eliminating screwed interfaces.
A specific version with a transfer line is also available.
The LPT6510 is used in the TRISHNA high-resolution thermal infrared (TIR) space-time mission, led by the French (CNES) and Indian (ISRO) space agencies.
Objectives: monitoring of water conditions and stress in continental ecosystems, monitoring of coastal waters, indoor monitoring of the urban environment. Applications to the solid Earth, cryosphere and atmosphere.
Launch date: 2025
CRYASSY are compact cryogenic assemblies incorporating a detector, a cryostat and a Pulse-Tube cryogenic machine, also known as IDCA: Integrated Dewar Cooler Assembly.
