Shell Tellus Hydraulic Fluids in Action
Tank-lifting company doubles hydraulic power unit oil drain interval with Shell Tellus S2 MX
Total Predicted Annual Customer Savings of $30,217
COMPANY: United Tank Lifting Technologies NV
COUNTRY: Aruba
APPLICATION: Hydraulic systems
SAVING: US$30,2171 total predicted annual customer saving
KEY EDGE: Shell Tellus S2 MX
United Tank Lifting Technologies NV (UTLT) provides tank-lifting services to the oil and gas sector, and specializes in lifting and repairing vertically installed, above-ground storage tanks used for oil and gas. The company wanted to review its lubricant supply to see if it could benefit from operational improvements.
In particular, the company required a high-quality lubricant for its Enerpac hydraulic power unit. The hydraulic power unit delivers fluid to a series of hydraulic jacks distributed equidistant around the circumference of a tank. To ensure even lifting of the tank, fluid friction must be minimal so that the fluid acts on all the jacks simultaneously. UTLT turned to Shell distributor Kuzeta Aruba for advice.
Kuzeta recommended that UTLT should change to Shell Tellus S2 MX high performance hydraulic fluid in the hydraulic power unit. The company switched to Shell Tellus S2 MX and found that the lubricant delivered reduced fluid friction and good stip–slick performance compared with its previous oil. It also reported an increase in oil-drain interval of 100%.
Kuzeta Aruba, with the support of Shell’s technical team, has delivered improved operational efficiency. As a result of doubling the oil-drain interval for its hydraulic power unit, UTLT has predicted total annual savings of US$30,2171.
“All of UTLT’s equipment is now lubricated with Shell lubricants based on the high-quality of the products provided and the good service support received from our supplier, Kuzeta Aruba NV.”

SHELL TELLUS S2 M
INDUSTRIAL HYDRAULIC FLUID
Shell Tellus S2 M fluids are high-performance hydraulic fluids that use Shell’s unique patented technology to help to provide the necessary protection and performance in most manufacturing and many mobile equipment operations. They resist breakdown under heat or mechanical stress, and help to prevent the damaging deposit formation that can decrease the efficiency of hydraulic power systems.
Applications
- Industrial hydraulic systems. With an extensive range of equipment manufacturer approvals and recommendations, Shell Tellus S2 M fluids are suitable for a wide range of the hydraulic power applications found in manufacturing and industrial environments.
- Mobile hydraulic-fluid power-transmission systems. Shell Tellus S2 M fluids can be used effectively in mobile hydraulic-power applications such as excavators and cranes, except where significant ambient temperature variations are encountered. For these applications, Shell Lubricants recommends the Shell Tellus V series.
- Marine hydraulic systems. Shell Tellus S2 M is suitable for marine applications where ISO HM-category hydraulic fluids are recommended.
Performance features and benefits
- Long fluid life – maintenance saving. Shell Tellus S2 M fluids help to extend equipment maintenance intervals by resisting thermal and chemical breakdown. This helps to minimise sludge formation and provides proven performance under the industry-standard ASTM D 943 Turbine Oil Stability Test to offer good reliability and system cleanliness. Shell Tellus S2 M fluids also have good stability in the presence of water, which can help to ensure long fluid life and reduce the risk of corrosion and rusting, particularly in moist or humid environments.
- Proven wear protection. Zinc-based anti-wear additives are incorporated to enable Shell Tellus S2 M to be effective throughout the range of operating conditions, including low-load and severe-duty high-load conditions. Their excellent performance in a range of piston and vane pump tests, including Denison T6C (dry and wet versions) and Vickers 35VQ25, demonstrates how Shell Tellus S2 M fluids can help system components to last longer.
- Maintains system efficiency. Shell Tellus S2 M’s enhanced cleanliness, filterability, water separation, air release and anti-foaming characteristics all contribute to maintaining or enhancing the efficiency of hydraulic systems. Shell Tellus S2 M fluids are formulated for fast air release without excessive foaming to help efficient hydraulic power transfer and minimise the cavitation-induced oxidation that can shorten fluid life.
