EPT Varnish Removal Products for Turbine and Compressor Lubricants and EHC Fluids

EPT lead

EPT manufactures lubricant filtration systems for the power and other critical industries.

Lubricant filtration technology for use in power turbines

EPT has worked for over two decades to advance lubrication maintenance and reliability for critical applications in power generation, manufacturing and heavy industry. It has maintained a focus on continuous improvement through research, and lubricant maintenance and testing technologies.

The company’s proprietary lubricant filtration technologies include ion charged bonding (ICB™), soluble varnish removal (SVR™), electrostatic contamination removal (ECR™), and total moisture removal (TMR™). These products have tens of millions of hours of proven performance on super-critical applications in some of the biggest power plants worldwide.

Removing turbine and compressor lubricant varnish

Lubricant varnish production is a problem that will affect most rotating equipment at some point in its normal service lifetime. All lubricants form dissolved breakdown products, which if allowed to accumulate to saturation will eventually come out of solution to form varnish deposits.

The key to prevent and remove varnish is to stop the accumulation of dissolved breakdown products. Removing the breakdown products maximises the performance of the lubricant and additive system, while eliminating the potential for varnish formation.

EPT offers a comprehensive four step programme that will not only remove varnish, but prevent the accumulation of dissolved breakdown products, eliminating the potential for varnish formation.

  1. Oil analysis for turbine lubricants: Send EPT a sample to receive a complimentary analysis and detailed report outlining the results EPT technologies can deliver.
  2. SVR™ System: Target and remove the primary cause of varnish deposits.
  3. NSD™ Filters: Reduce the friction that causes sparking.
  4. MPC (membrane patch colourimetry) Test Kits: For laboratories or on-site MPC testing.

Phosphate ester maintenance for electro-hydraulic control (EHC) systems

While the criticality of phosphate ester fluid quality in EHC systems is obvious, operators frequently struggle with inadequate or outdated equipment that is not capable of maintaining these fluids (Fyrquel®, Anvol® and Reolube®) in the necessary condition required for proper operation and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.

EHC fluid quality related failures and their resulting production losses can be virtually eliminated through EPT’s industry leading fluid maintenance and testing programme, the result of over 20 years of specialisation in EHC fluid applications.

EPT’s four part approach is comprehensive in scope, targets common weaknesses, and removes the contamination responsible for servo valve deposits. Our programme offers turbine owners and operators a clear path forward to protect their equipment from failure and reduce costs.

  1. Oil analysis for EHC: As a starting point, EPT’s detailed fluid analysis identifies issues and provide a clear path forward.
  2. ICB™ Filters: Move beyond acid removal and remove the contamination responsible for valve problems.
  3. TMR™ N2 Systems: Target the primary cause of EHC fluid breakdown.
  4. ECR™ Systems: Address the consequence of micro-dieseling.

Oil analysis services

EPT offers laboratory testing that provides a complete picture of fluid condition.

The EPT lab is set up as a starting point for users to understand the current state of their fluids and the risk of failure. The other key role EPT’s lab is to support existing customers to document results and demonstrate success.

EPT provides specialised testing for turbine fluid, EHC and other critical fluids. All tests adhere to American Society for Testing and Materials (ASTM) methods. The company offers a comprehensive list of analyses that are completed and interpreted by professional chemists and application specialists.

An initial assessment is offered at no charge. Routine and specialised test packages are available on a paid or prepaid basis.

What to Consider When Purchasing Varnish Removal Systems

Varnish removal technologies can be classified into two main categories: 1) Particulate removal including electrostatics, balanced charge agglomeration and depth media filters, and 2) Dissolved breakdown product removal including ion exchange and ion charge bonding technologies.

Resistivity, Fact or Fiction?

Resistivity is a critical performance indicator for phosphate ester (PE) uid quality. Low resistivity values are associated with electro kinetic wear, a common failure mechanism of servo valves.
