John Crane has announced the launch of the Type 93AX Coaxial Separation Seal – a next generation dry gas sealing solution engineered to help customers reduce emissions, improve equipment reliability, and lower operational costs.
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, test data indicates the mechanical seal reduces nitrogen consumption by up to 80 per cent, compared to conventional radial separation seals – offering significant efficiency and sustainability benefits.
The new product has been developed to address customers’ pain points across the energy and process industries, including oil and gas, power generation and clean energy.
Research has shown that contamination is a significant contributor to dry gas seal failures, making it one of the leading causes of unscheduled maintenance and equipment downtime. The Type 93AX is engineered to prevent oil ingress from the compressor bearing chamber, minimising this risk and supporting more reliable, continuous operation.
The Type 93AX is designed to mitigate both performance and financial risks by extending the reliability of the dry gas seal system and reducing demand on supporting infrastructure such as nitrogen (N2) generators and air compressors.
The Type 93AX helps contribute to sustainability goals through reduced emissions and lower energy usage. By cutting nitrogen use by up to 80 per cent, 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 per cent by 2040, further underlining the importance of solutions like the Type 93AX.
