Wide range of applications – main differences Mobile Applications
Industrial Applications
5000h – 10.000h
Up to 40.000h
Relatively small (oil circulation high)
Relatively large (oil circulation low)
Max. oil temperature Environmental temp
High (was 90°C, now 115°C (239F)) -40°C – 100°C
Medium (was 60°C, now 80°C (176F) Frequently ambient (20°C)
Risk of fluid contamination
High - oil mix by use of various hydr. accessories (Agriculture, Construction); condensation (water)
Low – consistent environment (facilities), exception: mining
