Atlas Copco and Linde Gas work together to provide helium solutions
Wilrijk, Belgium, July 2014: The high-pressure products manufactured by Atlas Copco reflect nearly a century of extensive experience in the field of high-pressure technology. Atlas Copco has had long-term, cooperative relationships with well-known global providers of industrial gases, providing them with gas process solutions.
In 2011, Linde purchased two sets of helium compressors for its helium provision facilities in Pixian, Chengdu. The project was to supply cooling helium for an international manufacturer of professional medical imaging technology products, primarily magnetic resonance imaging (MRI) systems. MRI systems require a continuous supply of low-temperature air to cool the magnetic coil of the scanner. This creates superconducting properties in the coil and ensures the current smoothly flows through it, generating a high-intensity magnetic field.
High volume rate, low maintenance costs and safe operation
A helium compressor is also required to exhaust the evaporated helium that is generated when producing an MRI. This can greatly affect compressor performance and stability. Therefore, Linde chose a helium compressor from Atlas Copco.
Atlas Copco’s helium compressor is specifically designed for low-density gases. The level-5 compressor features a low compression temperature and a gas-tight crankcase design to ensure that there is no gas loss or gas pollution when sending return air from the crankcase to the suction side. It features a high volume rate, low maintenance costs and safe operation, and it has been widely recognized throughout the world.
Stable operation since 2012
“Helium has the characteristic of very low, compression-specific heat, so the temperature of the helium can be increased to very high when compressing it. It also requires that air mixing be absolutely eliminated. Meanwhile, the MRI device requires no compressor downtime due to very long pre-cooling times or high operating costs. This requires a high-performing compressor. Helium compressors are designed to specifically meet the needs of helium conveying, including high operating stability and safety. This is the reliable guarantee of the whole liquid helium supply project!" Mr. Jun added.
Two sets of helium compressors are used for high purity and low purity helium conveyance. Since on-site testing in March 2012, the units have been in stable operation. As the After-sales Service Manager of Atlas Copco Western, Mr. Zhang Daipin observed the trial run at Linde’s Pixian location. He said, “Atlas Copco’s professional team adheres to a customer-centric service concept to safeguard that the product can stably and efficiently function with regular on-site services.”
