Manufacturer's description
Mobil SHC™ 800 Ultra Series comprises Mobil SHC 832 Ultra and Mobil SHC 846 Ultra, superior high-performance synthetic turbine oils designed for steam turbines, gas turbines, combined cycle gas turbine (CCGT) and turbo compressor applications operating under the most severe conditions. The series is specifically formulated to withstand the thermal stresses of modern high-output stationary gas turbines, providing exceptional resistance to thermal/oxidative degradation and outstanding keep-clean performance with targeted deposit and varnish control — helping to prevent bearing deposits, filter plugging, servo-valve deposits and valve sticking. The oils also deliver the exceptional interfacial properties, including strong steam and water separation, required by modern high-performance steam turbines, together with strong anti-wear protection that meets the load-carrying demands of geared turbines. Together these properties extend equipment protection, improve operating reliability and reduce unscheduled downtime, while extending oil life and lowering lubricant costs. Mobil SHC 832 and 846 Ultra hold builder approvals from MAN Energy Solutions and Siemens, and meet GE Power GEK requirements, ASTM D4304 (Types I, II and III), China GB 11120-2011 and DIN 51515-1/-2 specifications, giving operators flexibility across a wide variety of turbine types while avoiding lubricant misapplication.
Applications
- Mobil SHC 832 and 846 Ultra are superior high performance turbine oils designed for use in steam turbines, gas turbines, combined cycle gas turbine (CCGT) and turbo compressor applications under the most severe operating conditions. Modern stationary gas turbines operate at high power output and severe operation causes thermal stressing of lubricant that can result in bearing deposits, filter plugging, servo-valve deposits and valve sticking or short oil life. Mobil SHC 800 Ultra Series have been specifically formulated to provide exceptional protection against thermal/oxidative degradation and outstanding keep-clean performance with specific deposit and varnish control. Mobil SHC 800 Ultra Series also feature the exceptional interfacial properties, in particular steam and water separation, required for modern high performance steam turbines. Mobil SHC 800 Ultra Series strong anti-wear performance is designed to meet load-carrying requirements of geared turbines.
Performance & benefits
- Excellent water and steam separation• Supports efficient system operation and reduced maintenance
- Meets or exceeds key builder requirements for both gas and• Provides flexibility to operators
- steam turbines• Avoids lube misapplication and costly change-out
