Hydraulic oils for arctic conditions

Paul Boughton

Mobil SHC 500 hydraulic oils, in addition to being designed to help oil and gas companies operating in Arctic conditions improve safety, productivity and sustainability performance, have been proven to offer energy efficiency benefits in hydraulic equipment.  

Compared with standard mineral hydraulic oils, Mobil SHC 500 can help to reduce hydraulic system energy consumption by up to 6.2 per cent*, and as a result will display the company’s proprietary “Energy Efficiency” logo on packaging.

The Mobil SHC 500 Series has been engineered to help protect hydraulic equipment operating on offshore and onshore oil and gas rigs located in extremely cold climates such as the Arctic, Russia and Nordics. [Page Break]

At -400C Mobil SHC 500 is four times thinner than similar viscosity index conventional mineral hydraulic oils**, allowing it to circulate around the hydraulic system faster at start up, ensuring the lubricant is in place to protect machine components.  For hydraulic equipment operating in even colder conditions, ExxonMobil offers specialised products such as Mobil Univis HVI or Mobil Aero HF-A.

The Mobil SHC range includes gear, bearing, compressor, turbine and gas engine oils, which alongside their cold temperature performance and energy efficiency potential, have been developed to help extend the service life of machine components and last between three-to-six times longer than mineral oil based products, helping to reduce maintenance shutdowns.

*Energy efficiency relates solely to fluid performance when compared with conventional reference oils of the same viscosity grade in hydraulic applications. The technology used is able to achieve up to 6.2 percent efficiency compared with the reference when tested in a hydraulic system under controlled conditions. Efficiency improvements vary based on operating conditions and application.

** Based on comparative -400C Brookfield, ASTM D2893 test results, between Mobil SHC 525 and Mobil Univis N 46.
