Mobil SHC™ 626 helps Xinyu Iron & Steel Co., Ltd. Heat electric plant save US$ 2,100 annually

Power reduction of

1.5%

Iron and steel mill gearbox grease bearing oil

Situation

There are eight cooling towers in the Xinyu Iron & Steel Co., Ltd. Heat Electric Plant. The core equipment of these cooling towers are the gearboxes of the tower fans. These were lubricated with a mineral oil and were costly to maintain. Hence, the plant was seeking a cost-effective lubricant that could improve operational and energy efficiency while reducing total cost.

Recommendation

The ExxonMobil Lube Engineer conducted on-site inspections with the customer and recommended replacing the current mineral oil with Mobil SHC™ 626 coupled with Mobil Serv℠ Lubricant Analysis. As Mobil SHC™ 626 has excellent high-temperature oxidation stability, a low traction coefficient and high viscosity index, it was able to extend oil drain interval and improve the energy efficiency of the system.

Result

After implementing Mobil SHC™ 626 and Mobil Serv Lubricant Analysis, the plant managed to achieve a total annual savings of US $2,100. The benefits resulted from:

  • Decreasing the average working temperature of the gearboxes by 5°C (41°F)
  • Decreasing the electric motor amps by about 1.5%

*This success story is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used. ExxonMobil shall include Exxon Mobil Corporation and its affiliates.
