WOLFRATSHAUSEN, Germany, Nov. 05, 2026 (GLOBE NEWSWIRE) -- EagleBurgmann, a global leader in industrial sealing solutions, is marking 15 years since the first installation of CobaSeal, its innovative coaxial separation seal technology that helps energy operators reduce resource consumption, improve compressor reliability, and lower lifecycle costs.
Developed to address persistent reliability challenges in industrial compressors, CobaSeal protects dry gas seals from bearing-oil contamination while substantially reducing the nitrogen required for separation sealing. Its innovative coaxial design provides a reliable barrier between bearing oil and process gas, with non-contacting operation that minimizes wear across demanding operating conditions.
With more than 1,500 installations worldwide, CobaSeal has demonstrated its value in both new compressor installations and retrofits across the oil and gas, refining, petrochemical, and energy industries. Depending on the application and existing sealing arrangement, the technology can significantly reduce nitrogen consumption compared with conventional separation seals.
From First Installation to Global Adoption
CobaSeal was first installed in 2011 at the Nether Kellet compressor station in the United Kingdom, operated by National Gas (formerly National Grid). The installation addressed recurring bearing-oil contamination and dry gas seal failures. A retrospective documented maintenance-free performance of the original seal, demonstrating its reliability through demanding operating conditions.
The benefits extended beyond equipment protection. Previously, maintenance on the nitrogen supply system could require shutting down the compressor. As Jim O’Hare, an EagleBurgmann engineer involved in the original installation, explained:
“With the CobaSeal, this has changed. The vastly reduced nitrogen consumption ensures seal and compressor can continue operation while the system is serviced.”

Innovation in Action: Proven Results in Norway
At Equinor’s Kollsnes gas processing plant in Norway, recurring oil contamination had caused multiple dry gas seal failures and created significant maintenance challenges. With compressors required to operate continuously through the winter months, improving reliability was critical.
EagleBurgmann retrofitted an export compressor with a dry gas seal cartridge incorporating CobaSeal separation seal technology. The solution prevented bearing oil from contaminating the dry gas seal and achieved significantly lower nitrogen consumption than the separation seals on other compressors at the facility, with more stable consumption levels.
The project demonstrates how targeted sealing upgrades can address recurring equipment problems while reducing resource consumption and operating costs.

Supporting Reliability Across the Equipment Lifecycle
Designed for both new installations and existing equipment, CobaSeal can be integrated into standard compressor sealing arrangements, offering operators a practical path to improved performance without extensive equipment modifications.
Beyond its nitrogen-saving potential, the technology helps protect critical sealing components, extend maintenance intervals, and reduce the risk of unplanned compressor downtime. These benefits support the growing demand for reliable, resource-efficient operations across the energy and industrial sectors.
