Description:

Shell Tellus S2 MA fluids are high performance detergent based hydraulic fluids for use where emusifiable fluids are preferred. Using proven ashless anti-wear technology they provide reliable performance in applications where contamination by aqueous fluids, such as cutting fluids, or where cleanliness or control of solid contaminants is important.

Performance, features and benefits:

•    Protection in severe environments 

The established detergent and modern ashless anti-wear technology in Shell Tellus S2 MA fluids provides extra protection in challenging environments by: 

Preventing water accumulation Dispersing solid contaminants 
Preventing corrosion in presence of water Providing low-friction anti-wear performance 

Outstanding anti-wear and load-carrying properties in hydraulic and geared systems, especially under high load and low speed boundary lubrication conditions are demonstrated by the high Brugger and FZG load values. 

•Fluid life – Maintenance saving 

Shell Tellus S2 MA fluids have good resistance to thermal and chemical breakdown to ensure consistent performance and protection throughout the fluid drain interval. 

•Maintaining system efficiency 

Superior cleanliness in severe environments helps keep the hydraulic system functioning efficiently. This is supported by excellent air release and anti-foam characteristics. 

In addition, Shell Tellus S2 MA provides excellent filterability allowing the use of fine filters for extra protection and long equipment life. 

Smooth operation of the hydraulic system is supported by the low-friction additive system that helps reduce stick-slip behaviour under high loads or poorly lubricated contacts. 

Shell Tellus S2 MA has a minimum cleanliness of max ISO 4406 21/19/16 class (ex Shell filling lines) as defined by DIN 51524 specification for extra equipment and filter protection. 
 As recognised by DIN 51524 specification, the oil is exposed to various influences with transport and storage that could effect the cleanliness level.

Application:

•Industrial hydraulic systems 

Industrial and manufacturing applications including: Injection moulding machines 

Electronically controlled hydraulic equipment Mobile equipment 

Headstocks and hydraulic controls in automatic lathes (when a synthetic or semi-synthetic water-extendible metal working fluid is used). 

Where low start up and high service temperatures are encountered the use of Shell Tellus S2 VA 46 is recommended.
