Next generation seal introduced to the gas industry

The Type 93AX builds on John Crane's legacy of industrial sealing expertise with a robust, fail-safe design that remains operational even in the event of multiple failure scenarios. Designed based on direct customer feedback, the mechanical seal reduces nitrogen consumption by up to 80%, compared to conventional radial separation seals – offering significant efficiency and sustainability benefits.
The Type 93AX helps contribute to sustainability goals through reduced emissions and lower energy usage. By cutting nitrogen use by up to 80%, it decreases demand on N2 generation systems – a source of both energy consumption and cost.
According to the International Energy Agency (IEA), improving industrial efficiency could cut global energy use by 12% by 2040, further underlining the importance of solutions like the Type 93AX.
Mike Eason, chief technology officer at John Crane, said: “Our customers told us they wanted a separation seal that increases safety, efficiency, and reliability. The Type 93AX delivers on these priorities. It's designed to keep working in real-world failure conditions to protect their most critical assets, and reduce environmental impact, while driving down OPEX and CAPEX.
“The new seal is compatible with John Crane's dry gas seal portfolio and is supported by a global network of over 200 facilities, including manufacturing, sales and services, and 13 global turbo service centres in more than 50 countries. It can be sold as part of a bundled first-fit order or compressor upgrade, or supplied as a stand-alone product to meet customer-specific requirements.”
