Traditionally, mineral oils are used in hydraulic systems. Hydraulic mineral oils are harmful to the environment because they are derived from non-renewable petroleum sources and can cause damage to environmental ecosystems. When released into the environment, they can contaminate soil, water, and air. Mineral oils also have a high tendency to persist in the environment, causing long-term environmental pollution.
Biodegradable hydraulic lubricants, on the other hand, are designed to break down faster and more efficiently than traditional hydraulic oils.
Shell Panolin S4 HLP Synth EAL (EAL = Environmental Acceptant Lubricant) is an environmentally friendly and biodegradable hydraulic fluid based on saturated synthetic ester, which quickly degrades in nature. It provides extended oil change intervals and reduced maintenance costs, while offering premium wear protection.
The hydraulic fluid meets the requirements of ISO 15380 HEES and achieves a biodegradability of over 60% after 28 days according to the OECD 301B test. This makes the product an environmentally friendly choice that is particularly well-suited for use in environmentally sensitive areas.
With regular service, the oil can theoretically have an unlimited lifespan. This involves:
With an exceptional dry TOST lifespan of over 6,000 hours (modified ASTM D943 test), Shell Panolin S4 HLP Synth EAL offers extended oil change intervals. This results in less oil production, purchase, and disposal, which in turn reduces operating costs. The good oxidative stability reduces fluid degradation, filter blockage, and increased viscosity, which helps prevent component failure and frequent filter and fluid changes. (Source: Shell)
PANOLIN HLP SYNTH, the hydraulic oil used in the first test machine, was in such good condition after 14 years and nearly 37,000 operating hours that it didn’t need to be changed. Overall, the intervals between oil changes became much longer and performance increased. As a result, machine downtimes decreased, and the total costs of lubricant fell by up to 95 %.
