4K Helium Circulation Fan

Product Description

 

The 4K helium circulation fan is a centrifugal fan for closed-loop cryogenic cooling systems operating toward the 4 K temperature class, circulating cold helium gas to transfer cooling capacity from the refrigeration source to the application. It operates over a working temperature range of 4–350 K and provides a helium volumetric flow of 45 m³/h, a head of 260 m and an adjustable speed of 9,000–18,000 rpm. Designed for controllable nuclear fusion, superconducting magnets, superconducting cables and cryogenic research equipment, the fan shares a structure that has been successfully applied to hydrogen gas circulation. For loops operating toward the 4 K temperature class, the fan is configured so that the circulation rate can be matched to the cooling sequence, from initial cooldown to steady operation. This operational flexibility is valuable in magnet systems where the thermal load changes across the operating cycle. The closed-loop design retains the working gas while delivering stable cooling capacity.

Fans in 4 K class systems are selected on the duty point of the loop, not on nominal ratings, so we review the required flow, head and temperature and confirm the speed range and interfaces before production. Turbo Energy is developing additional performance models and can customize flow rate, head, operating temperature and connections. Manufacturing is carried out in our 20,000 m² facility in Hangzhou's Fuyang district, certified to ISO 9001, 14001 and 45001, with OEM cooperation and progress reporting at agreed milestones. We review the required flow, head and temperature before confirming the speed range and interfaces, and each unit is manufactured under ISO 9001, 14001 and 45001 management systems. Additional performance models are under development, and OEM cooperation with progress reporting is supported. Factory performance data is documented for review, so the delivered machine can be checked against the agreed duty point.
