01

Reduced BOG generation

Under normal operation, the insulated cold end does not require LNG recirculation, reducing return flow and additional boil-off gas.

02

Long-life sealing

Compensated dual-ring sealing and multiple axial and radial compensation configurations minimize friction and wear.

03

Stable system integration

A compact, precision-manufactured design supports reliable control and integration with the vessel fuel-gas supply system.

04

Verified reliability

Performance has been verified through long-duration continuous cryogenic operation tests.
