Six Performance Advantages
Comprehensive protection system for long-term reliable wind turbine main gearbox operation
Anti-Micropitting & Gear Surface Protection
Passes FZG micropitting grade 10, effectively suppressing gear tooth stress damage and extending gearbox service life.
Extreme Pressure & Anti-Wear Load Capacity
Outstanding EP/AW performance for high-load and complex shock conditions, protecting gear tooth integrity under extreme operating conditions.
Extended Oil Change Interval
Exceptional oxidation and thermal stability supporting ≥5 years / 40,000 hrs oil change intervals, dramatically reducing O&M costs.
Ultra-Low Temperature Start-Up
Pour point ≤−45°C ensures reliable cold-start and oil circulation in cold climates, suitable for high-latitude and high-altitude wind farms.
Anti-Foam & Air Release
Superior anti-foam and air release properties improve oil stability, reduce cavitation risk, and ensure efficient system operation.
Water Separation & Corrosion Protection
Good water separation and corrosion protection for offshore and high-humidity wind farm environments, extending gearbox component life.

Frequently Asked Questions
Technical Q&A about HITECSYN SMP Plus wind turbine gear oil
Which wind turbines is HITECSYN SMP Plus 320 compatible with?
HITECSYN SMP Plus 320 is suitable for onshore and offshore large wind turbine main gearboxes, compatible with mainstream gearbox brands and OEM turbine models, covering 2 MW to 16 MW+ platforms.
Which Flender certification revisions does HITECSYN SMP Plus hold?
HITECSYN SMP Plus holds Flender certifications Rev.13, Rev.14, Rev.15, Rev.16, and the latest Rev.16.2 — one of the few wind turbine gear oils in China to carry the full Flender certification series.
What is the oil change interval for wind turbine gear oil?
HITECSYN SMP Plus delivers an oil change interval of ≥5 years / 40,000 hours, far exceeding the industry-standard 3-year interval, significantly reducing wind farm O&M costs and unplanned downtime.
What is anti-micropitting wind turbine gear oil?
Micropitting is one of the most common gear tooth failure modes in wind turbine gearboxes, manifesting as fine surface pitting that reduces transmission efficiency and increases noise. HITECSYN SMP Plus passes FZG micropitting grade 10, effectively suppressing micropitting initiation and extending gearbox service life.
How does HITECSYN SMP Plus differ from biodegradable wind turbine gear oil?
HITECSYN SMP Plus is a full-synthetic formulation with outstanding all-round performance, suitable for most onshore and offshore wind applications. The HITECBIO EHF series is a synthetic biodegradable formulation designed specifically for offshore wind and environmentally sensitive sites, meeting REACH, VGP, and other environmental regulations.
