GAS SEAL SUPPORT SYSTEMS AND SOLUTIONS
Gas seal support systems
OVERVIEW
John Crane’s dry gas seal support systems are designed and manufactured for seal gas conditioning, controlled seal gas supply and performance monitoring of turbomachinery gas seals.
Each gas seal support system ensures clean, pressurised gas reaches the seal faces, maximising reliability and reducing contamination risks.
John Crane’s product portfolio of gas seal support systems ranges from general industry gas panels to highly engineered API 692-compliant modular designs.
John Crane systems can be supplied in compliance with international standards and specifications such as API 692, ASME, ATEX/CE/PED, SQL, GOST, NEC and IEC.

Common questions
What is a compressor seal gas system?
A compressor seal gas system is a critical, often API 692-compliant, arrangement that delivers clean, dry, pressurised gas to centrifugal compressor seal faces. This barrier gas prevents process contamination, stabilises seal operation and leakage. John Crane’s seal gas systems optimise pressure, filtration and flow to maximise dry gas seal reliability and compressor performance.
What components can be included in a gas seal support system?
A gas seal support system may include filters, regulators, valves, flow meters, pressure indicators, gas coolers, booster compressors and monitoring instrumentation. These components work together to supply clean, stable, controlled seal gas for reliable turbomachinery operation.
Are John Crane gas systems compliant with international standards?
Yes. John Crane gas seal support systems can meet major international standards, including API 692, ASME, ATEX/CE/PED, SQL, GOST, NEC and IEC. This ensures high-quality design, global compliance and safe, reliable system performance.
Can these systems be customised for specific applications?
John Crane gas seal support systems can be tailored with specialised filtration, instrumentation, materials, layouts and control system integration. Custom designs meet unique project, environmental or industry requirements to support optimal seal and equipment performance.
