Applications

Traditional methods for cleaning oil have been shown to remove only a small percentage of total contaminants.

Maintenance spending normally targets as little as 10% of the contamination in your oil and is not addressing key contamination that is responsible for turbine trips and lost production. At EPT, our lab will comprehensively assess contamination levels, determine priorities, and demonstrate how EPT’s family of lubricant cleaning technologies are able to clean the lubricant sample provided.

We have developed cleaning programs specialized for the following applications:

Electro-Hydraulic Control (EHC) Systems

While the criticality of fluid quality in EHC systems is obvious, operators frequently struggle with inadequate or outdated equipment that is not capable of maintaining these fluids in the necessary condition required for proper operation and reliability. Fluid analysis frequently under-reports contamination levels, leaving operators vulnerable to system failures and outages.

Turbine Lubricant Varnish

Lubricant varnish is frequently misunderstood as being an oil quality issue. The truth is that all lubricants form dissolved breakdown products, which if allowed to accumulate will eventually form varnish deposits. The key to prevent and remove varnish is to stop the accumulation of these breakdown products with a proven and widely used filtration technology. Removing the breakdown products maximizes the performance of the lubricant and additive system, while eliminating the potential for varnish formation.

Water Removal

Water is the most damaging contaminant found in hydraulic and lubricating systems. The complication is that water comes in three forms: free, emulsified and dissolved. Conventional maintenance technologies often will remove one form, but not all, which frequently results in the wrong technology being applied. The ingression rate and source of water also determines which technology is required, so that the water removal process does not increase oil oxidation.

Filter Element Upgrades

Large industrial facilities will typically use particulate filters from multiple vendors. Unfortunately, the efficiency of filters from different manufacturers varies widely, but are sold as being similar. Filter efficiency ratings are based off ideal laboratory conditions that don’t exist in the real world. To take a giant step forward in lubricant maintenance, dynamically rated filters are available that are tested against real-life applications where pressures, flow, and temperature all vary.
