SVR® lubricant conditioning system is here to help you solve lubricant varnish problems.
SVR lubricant conditioning system prevents antioxidants (amine and phenol) additive depletion, removes acids that negatively affect oxidative stability, and can even improve oil demulsibility to greatly extend the useful life of your oil.
SVR® restores the solubility of the oil by removing the soluble varnish causing contamination that other technologies can’t. By restoring solubility SVR® enables the oil to chemically remove previously formed varnish deposits and reduce MPC varnish potential numbers from condition critical red to condition normal green.
A complete recovery and maintenance solution for mineral-oil based turbine lubricants. SVR® targets and removes the dissolved varnish pre-cursors which are the cause of varnish. By removing these waste oxidation by-products, you restore the oils original solvency properties which forces any solid varnish deposits to be dissolved back into the oil where they are removed permanently.
Ion Charge Bonding (ICB™) removes soluble oxidation by-products and restores demulsibility during normal turbine operation without damaging additive chemistry. With the most advanced media, SVR™ has 4x more capacity than competing varnish removal systems.
Turbine oil varnish deposits form when oil becomes saturated with oxidation by-products from fluid breakdown. ICB™ goes where other technologies can’t to remove polar oxides on a molecular level. When varnish deposits are affecting servo valve response time, that means the oil is saturated. SVR™ addresses this by removing dissolved oxidation by-products and restoring the oil’s solubility. The restored oil dissolves deposits back into solution which can then be removed by the SVR™. The process repeats during recovery until the entire system and the oil are varnish free. That’s when you see a white patch. Once the varnish is gone, SVR™ continues to work by removing by-products as they form to prevent future deposits. ICB™ also slows anti-oxidant additive depletion to boost oil life. ICB™ is the only technology that treats the dissolved varnish during normal turbine operation to prevent varnish from forming.
DFE rated advanced media technologies provide the highest level of particulate capture and retention so your equipment operates unimpeded by contamination. The coreless filter element in every SVR™ delivers remarkably low ISO Codes, taking the dirt load off of critical system lube and hydraulic control filter elements (IGV, pump discharge). In addition to particulate control, the HP107 with VTM media also removes the insoluble oxidation by-products that are suspended in the oil, working hand-in-hand with the ICB™ media to rapidly reduce varnish potential and restore the health of your oil. The element is oversized to perform over a long element lifespan and to ensure low environmental and bottom line impact. To top it off, the HP107 element comes standard with an integral zero leak bypass so with every filter change, you get a new bypass along with peace of mind.
With us, you will work alongside industry experts and receive comprehensive oil analysis and results from interpretation to provide the best solution to extend your fluid life and make varnish vanish, for good.
Over the last 25 years, EPT has developed the world’s leading lubricant and fluid cleaning technologies.
While particulate removal technologies offer very important benefits, such as reducing wear, they are ill equipped to remove varnish because it can take up to 72 hours to precipitate or deposit after oil is cooled. Particulate removal technologies are capable of removing insoluble contaminants from a varnish saturated oil but they cannot prevent saturation and therefore cannot truly solve the varnish issue. In an effort to accelerate insoluble varnish precipitation, some particulate removal systems use a cooler on the inlet. This is an attempt to force dissolved varnish out of solution before it goes through the filter. Using an ion exchange or ion charge bonding system that can remove varnish and its precursors when they are dissolved is much more effective and will offer 24/7 protection regardless of asset operating condition.
Optimal lubricant varnish prevention using ion exchange requires a system that cycles the entire reservoir volume >1x / day through the filtration system. Because the flow rate is constrained based on the volume of ion exchange resin used, attention needs to be paid to the filter size. Be careful, some varnish removal systems take 90 days to cycle the reservoir volume one time. Don’t be persuaded to buy a system that’s a few $1000 cheaper when the flow rate is insufficient – size matters! For lubricants with high varnish levels requiring restoration, higher reservoir exchange rates may be in order.
The cost of ownership of a varnish removal system includes the initial cost of the system, maintenance and consumables over its lifetime. The latter can be calculated by the volume of the resin filter (e.g. per in3 or cm3 ). What you’ll find is that some systems will be up to 5x more expensive to operate than others. Special care is required when evaluating this key point. As stated above in question 2, the volume of resin used also determines the flow rate of the system, so attention must be paid to the filter size.
Quality vendors should be available for on-site start up and training as well as ongoing monitoring to document the success of the system. In addition, users need to evaluate the oil analysis used to determine initial oil condition and show success as standard testing often misses key indicators.
