The Kingdom of Bahrain, as one of the key diversified industrial hubs in the Gulf Cooperation Council (GCC), presents unique challenges for mechanical systems. With major sectors spanning metal processing (such as Aluminum Bahrain - ALBA), oil refining (BAPCO), maritime maintenance (ASRY), and massive infrastructure expansion, the operational load on hydraulic and transmission machinery is continuous. Operating in these environments demands more than standard lubricants; it requires heavily reinforced fluid structures designed to withstand the harsh local conditions.
Specifically, the Bahrain industrial market requires hydraulic transmission oils that can operate effectively under extreme ambient summer heat (reaching over 50°C), while maintaining critical oil film strength to prevent metal-on-metal wear. High atmospheric humidity combined with windborne marine salinity from the Arabian Gulf introduces a constant threat of water contamination and rust inside hydraulic loops, accelerating standard oil breakdown. Standard fluids oxidize rapidly, generating sludge that clogs sensitive proportional valves and servo systems.
Formulated with advanced polymers that resist molecular shearing under heavy load and high ambient operating temperatures, maintaining viscosity stability.
Enables swift separation of water from oil, neutralizing hydrolytic degradation and preventing rust in maritime marine applications.
Infused with zinc-based anti-wear (AW) additives and friction modifiers that deposit a sacrificial boundary coating. This significantly minimizes component wear inside high-pressure vane, piston, and gear pumps operating continuously under high-stress conditions.
Our Group II/III hydrocracked base oils, blended with highly effective phenolic and aminic antioxidants, provide outstanding thermal-oxidative stability. This formulation prevents oil thickening, acidic build-ups, and the formation of varnish on servo-valves.
Ensures immediate release of entrained air, eliminating cavitation risk in hydraulic systems. Rapid air release guarantees stable power transmission and protects hydraulic cylinders and pumps from destructive micro-diesel ignition damage.
