Steel Processing

Extensive hydraulic equipment is involved when positioning and working with steel. The hydraulic oil reservoir system includes high pressure pumps to create the needed oil flow to meet the needs of the steel working equipment. This constant pressurizing and throttling of the oil causes a significant amount of stress that leads to the formation of varnish and fine contaminates. Users may notice a brown, gummy varnish build up on various surfaces of the hydraulic system. This contamination, if left unchecked, may lead to sticking and/or failure of critical hydraulic control valves, positioners and components

Mechanical Filters Aren't Enough

Generally hydraulic oil systems include mechanical filters that use fine synthetic filter media to remove fine sediment, but these filters are not so effective in keeping the machine in good working condition. That's because a majority of the contaminants are submicron in size, or too small to remove with conventional filters alone. Kleentek electrostatic oil conditioners are able to capture these submicron insoluble particles and remove them from the oil.

Signs of contaminated hydraulic fluid:

• Brown, sticky film on oil-wetted surfaces
• Control valve sticking or failures
• Scored or damaged bearing surfaces
• Shortened life for the system's fine mechanical filters
