This paper highlights two main achievements which were performed by AIR LIQUIDE during the last decade in the field of low cost Joule-Thomson coolers. On one hand, in order to comply with new geometrical requirements, AIR LIQUIDE is able to propose a flat cooler. This compact geometry is enabled by a new, cheap, type of heat exchanger. It offers a better resistance to external vibrations. On the other hand AIR LIQUIDE has developed, in the frame of a commercial program, a complete cryogenic cooling system, composed of a dual flow Joule-Thomson cooler, a pressurized gas capacity equipped with a manifold block and a pyrotechnic actuator, and the requested pipes and connectors. The dual flow is enabled by flexion of a washer made of shape memory alloy.
