Shell Morlina S3 BA


Shell Morlina S3 BA is a premium-quality circulating oil that is designed to give excellent protection against wear and corrosion, and to prolong service life. With its outstanding water separation properties and low foaming tendency, it can help to optimise the efficiency of your operations. It is especially suitable for systems where water separation is a key issue. In addition, it meets both the Morgan advanced lubricant specification for super demulsibility and the Danieli super demulse specification.

Designed to protect

Shell Morlina S3 BA offers exceptional protection in heavily contaminated systems when other bearing and circulating oils would fail. It is designed to

  • maintain protective oil films, as its water separation characteristics help to ensure continuous and efficient lubricant films between moving parts to minimise wear and seizure
  • prevent corrosion, as its exceptional ability to remove water from the system helps to ensure that all parts are coated in oil and protected against corrosion.

Designed for long oil life

Limiting fluid degradation can help to prolong oil life. Shell Morlina S3 BA is designed to help your machinery to operate for longer without interruption – for reduced maintenance requirements and enhanced productivity. Compared with the critical Danieli requirements for superdemulsifiable oils, Shell Morlina S3 BA achieved

  • up to five times longer oil life for lasting protection, even under severe conditions.

Designed for SYSTEM efficiency

Shell Morlina S3 BA has been designed to provide exceptional water separation characteristics, which makes it highly suitable for hot, wet conditions such as those found in steel production plants. Compared with the industry minimum requirements, it offers

  • up to 37% better free water separation for efficient lubrication in wet conditions.
