With oil prices soaring by about 50% over the past two years, the demand for oil prolongation is increasing. Did you know that oil (especially hydraulic and lubricating oils targeted by electrostatic oil purifiers) can be extended in life "depending on management"? While any oil purifier can clean oil, to prolong its life, it is essential to remove oxidized contaminants (sludge). If oxidized contaminants remain in the oil, they will dirty the hydraulic system, increasing the risk of hydraulic issues even after oil changes. However, CleanTech's "Electrostatic Oil Purifier EDC" can remove oxidized contaminants (sludge) smaller than 0.1μm, allowing the oil to maintain cleanliness equivalent to new oil! ■ Benefits of Introducing EDC - Improved productivity through stable operation! - More than 80% reduction in waste oil! - Improved pump power consumption! (5-20%) ■ Example of Cost Benefits from Operating the Electrostatic Oil Purifier EDC Purifier: EDC-R25 model Oil conditions: Tank oil volume 2,000L, complete replacement every 2 years ⇒ Cost benefit: 453,000 yen/year, payback period: 2.03 years *For more details, please refer to the PDF document or feel free to contact us.

I believe everyone understands how important lubrication is for machinery. However, why do issues such as chocolate stalling, pump failures, and valve malfunctions occur when proper lubrication management is in place? Many of the causes can be attributed to the perception that lubrication management equals just changing to new oil, and the fact that very few factories statistically grasp the losses caused by failures. In fact, a certain survey in the UK indicated that the losses to the country due to lubrication could save £500 million annually, which is an enormous amount equivalent to 4% of the UK's gross domestic product. As equipment becomes more precise and faster, the importance of lubricants is increasing, and we must change our awareness of lubrication management. Our electrostatic oil cleaning machine, 'EDC', has celebrated its 50th anniversary and is highly praised by many customers for its ability to manage existing oil with a cleanliness level exceeding that of new oil. *Some have reported savings of over 10% of factory shipment value. We have extensive experience and know-how in managing oils used across various industries, including lubricants, hydraulic oils, and cleaning oils, so please feel free to reach out to us for consultation. *For more details on the product, please check the download link below.

The gearbox (gearbox) installed in wind turbines uses gear oil, but since it constantly splashes oil, oxidation deterioration is very severe. On the walls of the gearbox, there is a layer of oxidized degradation material more than 1mm thick, and oxidized degradation material also adheres to the gear tooth surfaces. The oxidized substances in the oil have a viscosity similar to glue, causing them to stick to metal wear particles, leading to troubles and damage in various parts. To replace the oil in the gearbox, a truck crane is required, which incurs significant costs. However, performing maintenance can also result in substantial damage. EDC removes oil-related contaminants generated during operation and maintains oil quality stability. It is a unique oil purification device that can reduce the burden on equipment. Clean Tech's EDC (electrostatic oil purifier) is widely adopted in wind power sites in Europe, continuously maintaining the oil in good condition within the generator. This also ties into efforts related to the SDGs, increasing interest in the reuse of oil. For more details about the machine, please check the download below.

【Preventing Hydraulic Equipment Failures Before They Occur】 ~Keep the purification system running even if the equipment is stopped~ The majority of hydraulic equipment failures are caused by a contaminant in the oil known as "oxidized sludge." Due to the nature of oxidized sludge, when the machine is operating at high temperatures, it becomes fine particles that dissolve in the oil, and when the temperature drops, it tends to stick like glue (gelatinous). This is why machines may not operate after a holiday, necessitating extended warm-up periods. Therefore, it is essential to keep the "purification system" running, especially now when human movement is restricted and downtime for machines is increasing. Additionally, selecting the right purification system is crucial. Since oxidized sludge can become fine particles or gelatinous, standard filters or centrifuges are often insufficient. With electrostatic oil purification equipment, contaminants can be adsorbed regardless of particle size, minimizing the generation of "oxidized sludge" and contributing to the "prolongation of oil life and prevention of equipment aging." CleanTech offers a variety of electrostatic oil purifiers. If you are facing the issues mentioned above or are interested, please feel free to contact us. 【Content Overview】 Oil management amidst restrictions on human movement *For more details, please refer to the PDF document or feel free to contact us.*

Just as iron experiences metal fatigue, oil also undergoes fatigue reduction, and it is common practice to replace it before it becomes a significant issue. In this context, a representative from a major company requested an investigation into the specification limits of oil, or its "lifespan." As a result of extensive research and experiments conducted in-house, it has become clear that "as long as contaminants are completely removed, the more oil is used, the better its properties become, and it hardly wears out, exhibiting longevity." In other words, as long as harmful sludge is removed, oil can be used for many years. By properly managing "oil," it is possible to prevent a decline in equipment performance and failures, leading to increased productivity.

Clean tech handles oil purification, cleaning, and cleaning devices such as lubricants and hydraulic oils. Since its establishment, we have been engaged in research on lubrication management and have developed and sold an electrostatic oil cleaning machine that cleans oil using electric power. The reason hydraulic machinery does not start immediately after a holiday (Monday sickness) can be broadly categorized into "locking of the hydraulic valve" and "increase in viscosity due to a decrease in oil temperature." This document explains the mechanism behind the occurrence of "locking of the hydraulic valve."

CleanTech handles purification, cleaning, and cleaning devices for lubricants and hydraulic oils. Since its establishment, we have been engaged in research on lubrication management and have developed and sold an electrostatic oil purification machine that cleans oil using electric power. Oxidation products of oil have high viscosity, adsorb to metal surfaces, and act like glue, sticking to other contaminants like a flypaper. The sliding surfaces become sandpaper-like, and when the sliding body moves over this surface, stick-slip occurs. This document explains a series of investigation contents.

The debris in oil varies greatly in shape and material, and its size ranges from molecular scale to several hundred microns. Moreover, there are many varnish-like semi-solid particles that are liquid at high temperatures but solid at low temperatures, which greatly differ from debris in other liquids. This document provides a detailed explanation of the "electrostatic oil purification method" that resolves contradictions based on the functionality of filters, such as the inability to remove debris smaller than 5 microns, as well as the "filtration mechanism."
