Non-contacting Gas Seal for Turbo Compressors Aura™ 120NS
Aura™ 120 narrow section gas seals enable the latest John Crane gas seal technology to be fitted into older equipment, bringing with it the benefits of non-contacting design. Gas seal technology eliminates the need for oil lubrication associated with contacting seals and the resulting need to address harmful emissions trapped in the oil.
Investing in retrofitting oil seals to dry gas seal solutions will increase the reliability of compressors and other rotating equipment. The Aura™ 120 narrow section design applies decades of retrofit experience to minimize upgrade costs and accelerate turnaround.
Oil and gas methane emissions are the second most important greenhouse gas source, accounting for ~18% of total climate human-related climate impact. Upgrading legacy compressors to dry gas seal technology can reduce methane emissions by up to 95 percent.
Product Description Aura™ 120NS
The Aura range represents the next generation of John Crane gas seals, designed to reduce seal-operating and transaction costs by implementing a common design approach across the range and delivering extended maintenance intervals. The new Aura 120NS provides solutions for compressor applications with small cross-section cavities.
- Wider performance envelope, including bidirectional operation
- Increased reliability for extended maintenance intervals
- Improved design for simpler serviceability
