Environmentally Friendly HETG Hydraulic Fluids and Lubricating Oils Based on Vegetable Oils

It has been recognized for a number of years now that the use of mineral oil-based lubricants poses certain environmental risks. Leakages, emissions and spillages when handling gear and lubricating oils lead to direct pollution of the surroundings and thus the environment. This fact led FUCHS to develop rapidly biodegradable lubricants based on vegetable oils and synthetic esters.

The PLANTOHYD N series of oils are based on vegetable oils. They represent an environmentally friendly alternative to mineral oil-based hydraulic oils and can be classified as HETG fluids according to ISO/CD 6743-4.

The advantages of PLANTOHYD N are:

Rapidly biodegradable (greater 90 % within 14 days according to CEC-L-33-A-93)
German Water Hazard Class WGK 0, i.e. generally not hazardous for water
Non-toxic, physiologically harmless
Free of heavy metals
Excellent viscosity-temperature behaviour because of their high natural VI
Excellent anti-wear properties
Extremely shear-stable Rapid air release
Minimal foaming
Insoluble in water
Good demulsibility characteristics
Applicable at tank temperatures ranging from - 27 °C to +70 °C

PLANTOHYD N products are fully compatible with all materials usually found in hydraulic systems. The base fluids used in these products are non-toxic. The fluids are free of heavy metals and chlorinated compounds.

Application:

PLANTOHYD N hydraulic oils can be used universally in all hydraulic and general lubricating systems. These pro- ducts should always be used whenever there is a danger of soil or water pollution following a leak or spillage. The greatest potential for such occurrences are in the construction, water, agricultural and forestry industries. The high viscosity index of PLANTOHYD N products give them multigrade characteristics.

We recommend that the miscibility and compatibility of these products with mineral oil-based hydraulic oils should be checked on a case-by-case basis. As stated in ISO/CD ECO, residual quantities of mineral oil should be kept to a minimum by flushing prior to refilling. Compatible internal finishes on tanks should be selected. Paint finishes which are not 2-part epoxy systems can display poor resistance to mineral oil as well as vegetable oils. In general, we recommend the use of stainless steel tanks. "Free" metals, e.g. tin from soldered joints or zinc from galvanized components should be avoided if possible. Filter systems should also be compatible with vegetable oils.

The powerful cleaning effect of these fluids can dislodge large amounts of dirt and contaminants and this can, in turn, shorten the life of filters. System filters should be cleaned or changed after about the first week of use with PLANTOHYD N. The ISO/CD ECO guidelines should also be observed. To maintain optimum reliability, any water which has collected in systems which have been shut-down for longer periods should be drained. Water or moisture problems can be reduced if filtering and drying equipment is fitted to tank breathers. According to ISO/CD ECO, water content during use should be kept below 0.1 %.
