Pulse Tubes

• Easy to integrate ǀ The reduced vibration levels and the robustness of the cold finger make it easier to integrate the system close to the application that requires cooling
• Increased reliability and useful life ǀ This equipment has a completely passive cold finger and the compressor pistons are held on flexible bearings that eliminate all contact with the casings
• Reduced cost ǀ The simplicity of the cold finger, the lack of moving parts, and the lack of hydraulic actuators, reduce the complexity of the cooler drive electronics, thereby reducing the system impact and therefore costs.
• Vibration levels that are compatible with space applications ǀ The remarkably low levels of vibration (a few mN) mean that these machines are compatible with the very stringent specifications for photo detectors.
• Compliant with the highest standards ǀ ECSS ESA space standards

• Air Liquide was selected by Thales Aliena Space to supply integrated solutions to cool Focal Plane Arrays around 50-60K in the frame of the Meteosat Third Generation (MTG) program.
• The Air Liquide LPTC cooler was also selected by Thales Aliena Space for one of its program.
• Airbus Defense and Space and the CNES selected the pulse tube cryocooler of Air Liquide advanced Technologies to handle the cooling of the new generation Infrared Atmospheric Sounding Interferometer (IASI-NG).

The compressor, component of the Air Liquide cryo cooling solution, is supplied by Thales Cryogenics B.V. The LPTC is developed by Air Liquide under CEA Licence.
