Aura® 220
Dry gas seal
Aura 220 reduces operational and transactional costs using a patented polymeric sealing device. Aura 220 can help reduce leakage rates by up to 15%, lowering operational costs while protecting the environment. An enhanced rotor design extends scheduled maintenance periods, and the optional bi-directional capability reduces the need for an extensive spares inventory.
Aura 220 provides the ultimate reliable operation in temperatures ranging from -50°C to 200°C/ -58°F to 392°F and pressures up to 3625 psi (g)/250 bar (g).
We have 12 service centres worldwide dedicated to dry gas seals. Our repair service restores dry gas seals and their support systems to optimal condition through expert disassembly, cleaning, inspection, and refurbishment - including static and dynamic testing. This process helps extend seal life, reduce downtime and improve compressor reliability by returning seals to like-new performance and ensuring continued operational integrity.
