K450 helium compressor

Oxford Cryosystems  launched our new K450 helium compressor in 2018, superseding the Coolstar Cryodrive. The K450 offers a more robust and efficient solution for delivering compressed helium to our range of coldheads, in addition to controlling the coldhead motor speed, allowing the user to optimise the performance for faster cooldown and longer service intervals.

The capability for closed loop control of cooling power and the easily integrated Cryoconnector software allows full incorporation into complex OEM systems.

  • Purpose-built helium compressor for Coolstar coldheads
  • Controls coldhead speed for optimised performance
  • Multi-drive capability enables up to 2 coldheads to be driven from a single compressor
  • Backwards compatible with all Coolstar coldheads
  • Long service interval of 30,000 hours for adsorber change
