Oil ESH use for hydrosystems high-loaded mechanisms. Oil ESH is middlingviscous distillate into which after deep selective clearing and deep dewaxing enter polymeric solidified and depressant additives.
It is intended for hydrocontrol systems high-loaded mechanisms (walking dredges and other similar machines). It is efficient in the range of temperatures from -40°C to +(80-100) °C.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
