This is an introduction to a case where a GE7FA unit was installed. This plant is a large power generation facility using GE7FA. Several varnish issues occurred at this plant, so research was conducted to resolve those problems, and deep cartridge filters were installed. After a 10-day test trial, the company decided to adopt EPT products for all units. [Overview] ■ Unit: GE7FA ■ Load Cycle: Peak Response ■ Oil Age: 4.5 years *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to a case where a GE7FA unit was installed. Last year, there were 14 startup failures and 3 unit trips caused by varnish. The lubricant analysis showed high varnish levels, but no measures were taken. After introducing EPT's technology, a visual inspection of the tank, bearings, and hydraulic components revealed that a significant amount of varnish could be removed in a short purification period. As a result, it was decided to install EPT's equipment to extend the oil's lifespan and to continue careful trend monitoring with RULER and MPC tests.

This is an introduction to a case where a GE7FA unit was installed. This plant has experienced several startup failures, and in 2007, a trip occurred due to lubricating oil varnish. The plant used an electrostatic oil purifier equipped with fine particle aggregation technology, but it was unable to reduce the high varnish levels. In preparation for the startup in the summer of 2008, the plant introduced EPT technology.

This is an introduction to a case where a GE6FA unit was installed. During inspections when the unit was stopped, varnish was observed on the surfaces of the bearings and load gears. Concerned users used an electrostatic oil cleaning machine and deep filter continuously for over a year, but the varnish levels did not decrease. To prevent unit trips, equipment from EPT was installed to resolve this issue.

The "SVR 1200-M" is a device that can safely solve varnish problems in lubricating oil. To remove soluble contaminants without affecting the additives in turbine oil, it uses ion exchange resin and EPT's ICB filter technology. This ICB technology is based on ICB products with 30 million operating hours of experience worldwide. According to analysis results from membrane patch colorimetric analysis tests (currently under ASTM standard draft) or QSA tests, it can dramatically reduce varnish problems in large gas turbines within 1 to 2 weeks as a proven result. 【Features】 ■ Restores ISO (NAS) grade ■ Restores oil hue and clarity ■ Small installation footprint ■ Simple piping system ■ Low running costs ■ The device operates simply by turning on the power *For more details, please refer to the PDF materials or feel free to contact us.

The "SVR" is a soluble varnish removal device used worldwide to prevent varnish formation in lubricants. Using ICB purification technology, it removes varnish contaminants dissolved in oil without affecting the additives in turbine oil. It can be installed at any time on the bypass line of the oil tank, and during turbine operation, it reduces the varnish that precipitates and deposits when the oil temperature decreases by removing the varnish dissolved in the oil. 【Features】 ■ Removes deposited varnish ■ Prevents stickiness of servo valves ■ Reduces ISO code (particle count grade) ■ Restores oil color and clarity ■ Compact installation area with simple piping *For more details, please refer to the PDF document or feel free to contact us.

Removal of acids and dissolved metals (ICB). The ICB filter module uses weakly basic anion resin to remove all acids and dissolved metals. Additionally, the ICB filter does not perform actual ion exchange (separation of neutral salts).

The TMR moisture removal system is a product designed to remove moisture and contaminants from lubricating oil and hydraulic fluid tanks. Moisture, contaminant particles, and metal ion contaminants can enter the oil tank in various ways. The TMR moisture removal system prevents the entry of moisture and contaminants by continuously supplying dry air into the headspace of the tank. The dry air that enters the tank absorbs moisture and exits through the vent. By constantly introducing dry air, it prevents metal components released into the atmosphere from seawater, industry, and agriculture from entering the oil tank. The required amount of air is very small, so the tank will not be pressurized. It cannot be used if the tank is under negative pressure or if a ventilation fan is installed, so please stop the operation of those devices. The TMR moisture removal system is a very user-friendly product made of high-performance hollow fiber membranes and an aluminum casing.

The only proven device in the world that can safely solve the varnish problem in lubricating oil. In the past, electrostatic oil purification devices have been recommended as a measure to remove varnish from lubricating oil. While electrostatic purification seems effective, it eventually loses its ability to lower QSA and MPC values. The reason for this is that electrostatic oil purification devices can only remove insoluble substances, and they cannot eliminate varnish that is extracted from the lubricating oil. What is certain about the varnish problem is that the oxidation byproducts of lubricating oil are varnish. Soluble contaminants, which are precursors to varnish, accumulate and cause chemical reactions, ultimately producing high molecular weight monomers and polymers, which extract varnish from the oil and lead to sludge deposition. The ICB technology built into EPT's SVR (Soluble Varnish Removal) system is an oil purification device that removes soluble contaminants before they turn into varnish.
