Advanced Lubricating Fluids Engineered for High Shear Stability and Critical Machinery Components
As the main economic powerhouse of Indonesia, the Jabodetabek area (Jakarta, Bogor, Depok, Tangerang, Bekasi) operates as a mega-industrial cluster. Large industrial parks like MM2100, Jababeka, and EJIP host heavy manufacturing plants, chemical processing facilities, and automotive assembly lines. The port of Tanjung Priok handles millions of TEUs annually, relying on high-capacity gantry cranes, container stackers, and dockside heavy machinery.
Operating hydraulic systems in Jakarta presents significant environmental challenges. With average temperatures hovering between 28°C and 34°C and humidity levels frequently exceeding 80%, hydraulic fluids are highly susceptible to oxidation, thermal degradation, and water contamination. Conventional hydraulic oils quickly break down under these conditions, causing varnish formation, servo valve sticking, and micro-pitting in pumps. High-grade anti-wear hydraulic oil formulated with top-tier base oils and shear-stable additive chemistry is crucial to protect critical infrastructure from premature wear and unplanned downtime.
Anti-wear hydraulic oil relies on zinc dialkyldithiophosphate (ZDDP) or ashless (zinc-free) additives to establish a sacrificial protective film. Under high pressure and sliding contact (such as in vane or gear pumps), localized micro-temperatures trigger a chemical reaction in the AW additives, forming a metallic phosphate film on steel surfaces. This barrier prevents metal-on-metal friction and significantly reduces mechanical wear.
For Jakarta's marine, port, and construction industries, we provide dual-action formulations that offer outstanding hydrolytic stability. If water enters the hydraulic system due to high humidity or condensation, our oil separates quickly from water (demulsibility) and resists chemical breakdown, preventing acidic build-up and the corrosion of yellow metals like bronze and copper in high-precision piston pumps.
In tropical zones like Jakarta, hydraulic equipment undergoes extreme temperature fluctuations. During cold starts in air-conditioned plants or morning maritime operations, the oil must flow freely. During long hours of continuous operation under heavy loads, ambient heat can cause the oil to thin out excessively, resulting in interior leaks and drops in pressure.
Our premium hydraulic oils feature high Viscosity Index (VI) formulations. They maintain structural integrity and a stable lubricating film across a broad temperature range, ensuring consistent volumetric efficiency, lower pump wear, and reduced energy consumption.

The lubrication industry is moving toward high-efficiency, environmentally friendly products. Conventional ZDDP-based anti-wear hydraulic oils are under scrutiny due to potential environmental impacts and restrictions on heavy metal disposal.
Our research and development program focuses on developing advanced ashless (zinc-free) anti-wear fluids. These next-generation oils eliminate environmental risks, offer superior filtration down to 3 microns, and prevent filter blockage even when contaminated with water. We are also optimizing biodegradable synthetic esters to help marine and dredging operations near Tanjung Priok protect local water systems.
Whether you operate heavy equipment, precision manufacturing machinery, or maritime transport networks, using high-performance lubricants is key to maximizing operational efficiency and reducing downtime.
By choosing Longhai Lubrication Technology, you get a dedicated engineering partner. From tailored formulation development to fast export handling and technical support, we help keep your business running smoothly.
Common technical questions answered by our lubrication engineers.
For most indoor manufacturing machinery and injection molding systems in Jakarta, ISO VG 46 is standard. Outdoor systems subjected to direct tropical heat (such as excavators and port cranes) often perform better with ISO VG 68, which maintains a stronger lubricating film. Always consult your equipment's manual for specific viscosity recommendations.
ZDDP-based oils use zinc and phosphorus compounds to form a sacrificial wear-resistant barrier. Ashless hydraulic fluids use sulfur-phosphorus organic chemistry without metal ions. Ashless formulations reduce environmental impact, prevent heavy metal contamination, and provide better filtration through fine system filters.
High humidity leads to water condensation inside reservoirs. If the oil has poor demulsibility, it forms a milky water-in-oil emulsion. This reduces oil film strength, causes cavitation, speeds up additive depletion, and can lead to rust on critical machine surfaces. Our formulas are engineered for rapid water separation to protect your systems.
We test kinematic viscosity at 40°C and 100°C, viscosity index, pour point, flash point, demulsibility, air release time, and copper corrosion performance. These tests verify that every batch meets ASTM and DIN standards before leaving our facility.
