MEGIN Sustainability: Zero Helium Boil-off Technology

Liquid helium is a critical, non-renewable resource for Magnetoencephalography (MEG), and its price has surged by up to 200% in the last decade. MEGIN’s Internal Helium Recycler (IHR) addresses this challenge by circulating helium in a closed-loop system, virtually eliminating the need for weekly refills. Operating Principles & Phases:. Data Acquisition Phase: During active MEG measurements, the cryocooler cold head and compressor remain offline to ensure zero magnetic interference with brain signals., Recycling Phase: During periods of inactivity (typically at night), the system collects evaporated helium gas and reliquefies it within the Dewar vessel.,. Automated Management: The TRIUX™ neo workstation features an integrated scheduler that allows users to monitor the recycler’s status and automate the transition between measurement and liquefaction modes. Key Benefits:. Cost Efficiency: Significant reduction in annual operating expenses, with estimated helium loss kept under 50 liters per year., Extended Intervals: The system provides a 365-day refill interval, maximizing machine uptime and reducing maintenance-related downtime., Environmental Responsibility: By eliminating the waste of a scarce resource, the IHR provides a more sustainable pathway for long-term clinical and research neuroimaging.
