Hydraulic Oil Refurbishing

Washington Marine Cleaning recycles Phosphate Ester hydraulic fluid and regular hydrocarben hydraulic fluids. Clean oil is a very important part of any hydraulic system and WMC has the equipment and people to clean the largest of hydraulic reservoirs. WMC can quickly bring the highest of TAN numbers in very large reservoirs into spec. 

Industries all over the world employ mechanical lubrication fluids in various applications. All of the applications and there systems have a common necessity for a particulate and water free environment. Industry standards have been to keep water and particulate levels as low as possible at all times.

There are different approaches to removing water i.e. absorptive filtration, centrifuges, and coalessors. These three methods will remove free water from the fluid leaving dissolved water behind. The only method for complete water removal from hydraulic fluids is Vacuum Dehydration.

Washington Marine Cleaning is now offering hydraulic fluid refurbishment services and rentals. We own and operate a fleet of oil recycling units. Our latest addition is our 20 GPM Baron and Associates Vacuum Dehydration Unit. This unit can be used in a kidney loop configuration, or set up to continually circulate on a reservoir. Either way will yield the same desired affect, the elimination of water, to below 100 ppm, in the subject system. Our Vacuum Dehydrator also contains onboard particulate filtration and monitoring capabilities. A digital display providing real time ISO particle counts lets our customers know the cleanliness level of their hydraulic fluid at any time during processing.

Washington Marine Cleaning is available on a 24hr per day 7 days per week basis, to help with anything from planned maintenance shutdowns to night and holiday emergency responses.

 If Total Acid Number, TAN in your Phosephate Ester (Fyrquel Oil) is a problem, Washington Marine Cleaning has a large Ion Exchange Resin bed to quickly remove acids and control TAN in the largest of reservoirs.

 

 

Flushing Machine

 

 Hydraulic Oil Flushing is fast and simple when the machine is big enough to produce the Reynolds numbers you really need. This 75 hp 190 gpm hydraulic flushing machine is perfect to clean newly fabricated systems or old systems that have been contaminated by wear, broken components or recently upgraded and in need of pickling. Machine is fitted with 6 Zinga LE type cartridge filters and dual Denison pumps with had sdjustable pressure regulating valves.

EHC/Phosphate Ester

Hydrolytic breakdown is one of the largest concerns facing today’s users of Phosphate Ester EHC lubricants.  Hydrolytic breakdown occurs by exposing oil to heat and water during normal operation.  Once out of OEM parameters, the oil requires specialized treatment to bring it back into spec.

Hydrolytic breakdown causes the formation of acidic compounds in the oil, resulting in an exponential rise in total acid number (TAN).  Historically, Fuller’s Earth or Activated Alumina have been the recommended acid scavenging media to address this issue.  However, both media’s have their own negative contribution to the oil.

Although an effective acid scavenging media, Fuller’s Earth has a history of leaching detrimental heavy metals back into the system.  Activated Alumina, also an effective acid scavenging media, creates salts in the oil.  These salts adhere to metal parts, causing wear to surfaces.  Over time, the leaching of heavy metals or the addition of salts into any system can lead to a higher TAN than before.  Ion Exchange technology can reduce both the TAN and resistivity without negatively effecting to the oil.

Washington Marine Cleaning has the technical expertise, equipment and personnel to return our customer's out of spec oil to a like new condition.  With the latest in Ion Exchange technology and flow rates to 20gpm Washington Marine Cleaning can guarantee the short turnaround time our customers need.  Washington Marine Cleaning's Ion Exchange process has NAVSEA approval for use onboard U.S. Naval vessels.
