Helium recovery system

University of Jyväskylä (JYU) seeks a helium recovery system consisting of a helium gas collection unit, a liquid nitrogen based helium purifying unit and a helium liquefier unit. The helium recovery system must be dimensioned for minimum 55 litres of liquefied helium per day and high degree of computer-aided automation in operations. The system needs to be fully metallic with storage tanks suitable for outdoor placement under wind shelter.

University of Jyväskylä (JYU) seeks a helium recovery system consisting of a helium gas collection unit, a liquid nitrogen based helium purifying unit and a helium liquefier unit. The helium recovery system must be dimensioned for minimum 55 litres of liquefied helium per day and high degree of computer-aided automation in operations. The system needs to be fully metallic with storage tanks suitable for outdoor placement under wind shelter that is mostly protected from direct sunlight, temperature can vary between -40 C and +40 C. The helium recovery system includes helium collection, purification and liquefaction units. Surrounding infrastructure such as helium collection lines, electricity and cooling water exist and are not part of this call for tenders. The system must have documented ability to provide helium recovery rates > 95%. All components of the recovery system must be new. Used or refurbished components are not accepted. The system will be installed at the Nanoscience Center at the University.
