The PLANTOGEAR 220, 320, 460, 680 S products can be used as a universal industrial gear oil in new gears as well as in used gears. New gears should be flushed and rinsed before applying PLANTOGEAR S. New gears are usually partly filled with mineral oil based corrosion protection and running in oils after manufacture. If they are not completely flushed, the running in and the corrosion protection oil remains in the gear and may contaminate the PLANTOGEAR S products. Under unfavourable conditions this can result in increased foam values and this can affect the biodegradability of the PLANTOGEAR S products negatively.

The content of the residual mineral oil should, therefore, be reduced as recommended in the ISO 15380 guideline, table A1 (guidelines for changing fluid from mineral based oils to environmentally acceptable fluids) to a percentage of approximately lower than 2% mineral oil in PLANTOGEAR S. Old gears should also be flushed and rinsed before changing over to PLANTOGEAR S in order to reduce substantially the concentration of the residual mineral oil based product. The internal tank and gear coatings should be compatible with ester based products.

Paints which are not compatible to esters are not recommended to be used. In general two components coating systems can be used with ester based products. The use of stainless steel tanks or stainless steel filter housings is recommended. When deep filtration filters are used, the good solvency, dissolving properties of the PLANTOGEAR S products can reduce the filter life. Clean/check or replace the oil filters in the system after 1 week after changing over to PLANTOGEAR S products.

To ensure a safe operation, when using PLANTOGEAR S products in gear and circulating systems, remove any water that may have penetrated the systems before start-up or after longer periods of down-time. We recommend the use of suitable dryer systems and filtration units. Use ester-resistant compatible sealing materials and plastic materials in general. We recommend the use of viton material in dynamic stressed seals. Observe the change-over recommendations according to ISO 15380.
