The Game-Changer for Helıum Refıll Operatıons
AUTOMATED HELIUM FILL TOOL
Revolutionize Your Helium Refill Process with Precision and Automation
The Automated Helium Fill Tool, developed by ECHO Magnet Services, is a one-of-a-kind service tool that simplifies helium refill operations while minimizing risks. Nicknamed the "quench defeater," this advanced tool alleviates the stress and technical challenges commonly faced by engineers during liquid helium refills in the field.
Challenges in Traditional Helium Refill Operations
• Risk of magnet quench causing operational downtime.
• Issues with dewar and magnet manometers or frozen pressure sensors.
• Helium regulators failing to maintain stable push gas pressure.
• Constant manual monitoring of magnet and dewar pressures.
• High physical demand on engineers, especially in mobile MRI scenarios.
• The critical risk of missing the end of transfer, which can damage the magnet.
How the Automated Helium Fill Tool Solves These Problems
This microprocessor-controlled tool ensures precise pressure measurement and adjustments, eliminating all the above challenges.
Constant Dewar Pressure
Maintains stable dewar pressure throughout the transfer, increasing helium refill efficiency
Automated Monitoring
A built-in timer reminds engineers to record helium levels at regular intervals.
Precise End-of-Fill Detection
Accurately determines the end of the helium transfer before audible warnings (whistles) occur.
Data Logging
Logs pressure values second by second, providing invaluable data for analysis in the event of a magnet quench.
