Helium Compressor 80g/s

Hélial 4012  Liquefier-Cooler connected to Supratech station

Pumping System decreases the helium bath temperature down to 1.8 K inside the cryostat.

Pumping System allows decreasing the helium bath pressure down to 13 mb with a gas flow around 4 g/s.

It is made up of two Alcatel roots pumps (series 8000) with 4700 and 9700 m3/h of pumping speed and three primary pumps (1900 m3/h).
