The Helium Circulation Cryogenic System Qcryo is a new-generation, multifunctional, high-efficiency cryogenic solution. It effectively transforms a standard commercial 4K cryocooler into a high-quality cold source with significantly reduced vibration and lower temperatures.

The cooling power is transmitted via ultra-insulated flexible lines to various continuous-flow cryostats. Integrated with a gas handling system, Qcryo forms a closed-loop configuration that enables cooling of remote continuous-flow cryostats to below 2.5 K—without consuming liquid helium

(optional configurations achieve <1.8 K or even 1.3 K).

Qcryo can be combined with:

• Sub-K cryostats to form a dry, ultra-low vibration sub-K system with base temperatures below 800 mK
• Continuous-flow He-3 cryostats to achieve a dry, low-vibration continuous-flow He-3 system with base temperatures below 350 mK
• Single-shot He-3 cryostats to realize a dry, low-vibration single-shot He-3 system with base temperatures below 280 mk
