Using cartridge mount hollow shaft feedthrough in adr adiabatic demagnetization refrigeration
Adr adiabatic demagnetization refrigeration need reliable rotary feedthroughs that don't leak.
Cartridge Mount Hollow shaft feedthrough offers magnetic sealing for rotating shafts under vacuum. The design uses ferrofluid trapped in a magnetic circuit.
Quantum computing systems operate at millikelvin temperatures. Standard seals often fail at these extremes.
The magnetic fluid is stable at temperatures from -40°C to 80°C.
They also work longer between maintenance checks.
Compared to mechanical seals, ferrofluid seals handle higher speeds.
Customers in quantum computing choose this type of seal because it's quiet and doesn't need lubrication.
Installation is straightforward: mount the flange, connect the cooling lines if needed, and rotate the shaft to test.
If you're replacing a Rigaku system seal, check the flange type and shaft diameter first.
The magnetic fluid forms a barrier that prevents gas flow.
Operating speeds can reach 3,000 RPM in some configurations.
