Hydraulic oil additive development has recently been focused on enhancing energy efficiency, performance and environment friendliness. One of the main innovations incorporates advanced polymer-based viscosity index improvers like Evonik’s Dynavis technology which help hydraulic systems operate efficiently by preventing their oils from getting too thick or thin depending on temperature. As a result, it helps save energy and reduces wear and tear of machine parts.
In addition, there is a current trend towards use of ashless additives as opposed to the older versions that contained zinc as they outperform them especially in reducing sludge deposits and promoting cleanliness in systems using hydraulic oils. This switch not only enhances long life expectancy for hydraulic systems but also conforms with strict environmental codes of practice.
Further still, the utilization of Gas to Liquid (GTL) base oils in hydraulic fluids such as those listed in Shell Tellus portfolio signify another breakthrough in hydraulic technology advancement. GTL oils are known for their high viscosity index and excellent thermal stability therefore making them suitable for high performance applications while at same time reduce filtration frequency demand.
