- No contact of seal faces. In normal operation, seal faces separate and generate a sealing gap preventing friction and wear which prolong seal duration.
- Low power consumption due to non-contacting faces. Seal faces generate significantly less heat and torque, and will not affect turbine's stability.
- Self steam lubricated. Reacts sponteneously to maintain normal sealing gap.
- Less power requirement. Power consumption of gas seal is only 10%~30% in comparison to traditional wet seal; eliminated carbon emission and cost of wearable materials and support systems.
- Durable & reliable, relieved of turbine's bearing & oil steam contamination, maintaned clear & clean operating space.
