Kelvinox®HA dilution refrigerator is ideal for applications requiring high cooling power and enhanced experimental access such as quantum computing.

  • Achieves more than 350 µW of cooling power, ideal for demanding experiments with high heat dissipation such as microwave cavity losses
  • Less than 10 mK stable temperature: ideal for low temperature demagnetisation experiments
  • Additional line-of-sight access ports, enabling a range of services to the IVC and sample space for the most demanding applications
  • Improved experimental access with inserts, which provide a wide range of access ports
  • Delivered with a gas handling system, which is fully automated and enables complete operation of a dilution refrigerator using sophisticated software and virtual instrument drivers for LabVIEW

The KelvinoxHA is made up of a primary insert and a dilution unit. It is compatible with IntegraAC, the recondensing liquid helium cryostat. IntegraAC has been developed to significantly reduce the consumption of liquid helium by recondensing helium gas evaporated within the system, which would otherwise be vented from the cryostat. This decreases the frequency of helium refills. Cryogenic systems can be kept cold continuously, even when in stand-by mode, leading to greater freedom to schedule experimental time.

Flexibility: The KelvinoxHA can be used for a wide range of applications

Versatile: This is an ideal platform to customise your own experiment

Ease of use: All inserts are supplied with a gas handling system enabling automation of the insert cool down

Cost-effective: This dilution refrigerator can also be integrated into a helium recondensing dewar to minimise helium consumption
