Liquéfacteur à hélium automatisé

ATL160 et ATL160+ de Quantum Design

Les liquéfacteurs à technologie avancée (ATL) sont des condenseurs à hélium basés sur un refroidisseur. Il s'agit d'unités mobiles à l'échelle du laboratoire qui permettent la récupération et la liquéfaction de l'hélium gazeux qui est généralement perdu par évaporation et transfert d'hélium dans les installations de réfrigération.

Plus d'informations

The ATL uses a Gifford-McMahon (GM) cryo-cooler to liquefy helium gas. The GM cryo-cooler has a closed helium gas loop that is pressurized by a compressor. The compressed helium gas is then expanded in the cold head of the liquefier which generates low temperatures that cool down the dewar and the helium gas inside.

The helium liquefier has no sophisticated installation requirements and can easily be operated in any laboratory. A touch-screen panel allows easy control of the automated system. The ATL can use both helium gas from a high-pressure cylinder and recycled gas from a cryogenic experiment.

Thanks to the liquefier’s outstanding design, the helium is automatically liquefied with very high efficiency. The system features an average rate of 22 L/d (ATL-160). Depending on the mode of operation, this rate can even be higher.

As an ATL unit can simply be rolled to the cryogenic experiment, the liquid helium can be directly transferred. This saves time and reduces helium losses.

The ATL160+ could liquefy more than 30 liters/day of liquid helium, due to its patented technology.

"The Low Temperature Laboratory of the Institute of Nuclear Research of the Hungarian Academy of Sciences provides liquid helium for research work since 1973. A country-wide liquid helium delivery service was established in cooperation with Linde Magyarország Zrt. (local branch of Linde AG) for ’small costumers’ e.g. NMR spectrometers. To keep the supply safety we exchanged our former soviet-made helium liquifier (running since 1986) for an ATL-160. It was commissioned in January 2014. The helium gas collection and handling system was kept. A homemade helium gas purifier was constructed to provide the suitable gas purity for ATL."
