1 Advance Guard for Energy saving Cost reduction Machinery Maintenance ZD SERIES Filter & Electrostatic Oil Purifier Patent number / / Sustainable solution for machinery maintenance! Integrated electrostatic - ion type oil purifier

2 By utilizing ZD oil purifier, customers will say goodbye to financial burden incurred by expensive oil price and quantities of waste oil. Zedal guarantees its prominent economical efficiency. Principle Unlike existing conventional filters, ZD series utilizes the principle of electrostatic ion. As contaminated oil passes through the electrode, equipped with an electrostatic dielectric, various kinds of impurities in the oil are removed and attached to the dust collector. It is circulating purification system that only supplies clean oil into the tank. Zedal inc. provides the latest oil purifiers which eliminate impurities up to 10 micron during its first operation and separate moisture (20,000 ppm) secondly. Normal filters are able to purify the particle size of 5 micron to the utmost. However, ZD series collects and removes 0.02 micron impurities with tertiary electrostatic ion system. As premaintenance equipment, ZD series will be the ACE in your factory since they prevent oil oxidation and maintain proper oil viscosity so as to supply clean oil.

3 ZD-1000 INTEGRATED ELECTROSTATIC ION TYPE OIL PURIFIER Length : 110cm Width : 60cm Height : 100cm Power Consumption : 3 phase, 220V, 500W PUMP : Trochoid 3/4 21 min Collector : Porous fibroid material Primary filter : SUS 304(1,300 Mesh) Secondary filter : Paper Features and Effects 1.Conventional filter type purifiers were unable to remove foreign substances below 5 micron, whereas ZD series eliminates extremely infinitesimal particles of pollutant (below NAS 7 level) and reduces them to clean oil. As a result, various impurities that speed oil oxidation, below 5 micron, are eliminated in advance. According to the statistics, the oil purifier could not only prolong the service life of oil but save oil and electricity by 90% and 15% respectively, reduce failure rate by 70%, and decrease machine abrasion. By making use of the equipment, you could obviously not only save energy but reduce cost. 2.The equipment together with other facilities conducts purification, which reduces loss of production, improves productivity, and saves labor expenses through automatic functions. 3.Each additive in oil could be free from any negative influences, and the oil service life could reach more than seven years. 4.In the process of filtration, oil does not generate bubble, and water separation could reach 20,000 PPM. For filtering oil containing quantities of water, the static oil purifier is equipped with oil-water separator. 5.The circulation mode cleans pipes inside the machine and removes the oil (below 460cst with a 60cst circulation mode) with high viscosity that are unable to be filtered by other oil purifiers. 6.It is simple, convenient and secure to operate the equipment. The filter (SUS MESH) could be used repeatedly after being cleaned with absorbents. The three-phase 220V 500W consumed power could save electricity to a great extent. Specification All items are adjustable for better quality improvement.

4 Economic effects Annual save of equipment maintenance expense could purchase a new oil purifier % equipment maintenance expense, accounting for 1.3% of sales volume, could be saved. Loss caused by the one hour halt of the equipment is equal to price of a new oil purifier. Lubricant expense can be saved below 0.1% of sales volume. Necessity of lubrication management 1.As the general development trend of modern industry is high performance, speediness, and ordinary industrial equipment is gradually shifting to the full automation. If accidental failure occurs in the equipment, the loss would cover not only maintenance but immeasurable losses incurred from the halt of equipment. 2.Over 70% of mechanical failures are caused by improper lubrication management. It is estimated that proper lubrication management brings considerable economic benefits, equivalent to about 4% of GNP of the country. (Research report on lubrication management status-friction. JOST report, the UK) 3.New oil pollution management system is to periodically purify the oil used in the mechanical equipment for the purpose of preventing lubricating oil, prolonging oil service life, saving expenses, avoiding mechanical failure in advance, and decreasing the expenses caused by spare parts replacement and maintenance. Thus, mechanical performance, productivity and quality could be guaranteed so as to reduce cost in enterprise operation. 4.Detailed implementation is as follows; firstly, to accurately check and analyze the management status of each mechanical oil used in the factory; secondly, to set the standard for the pollutant use limit in accordance with the mechanical performance and for the purpose of guaranteeing the management benchmark; thirdly, to execute the pollution management system as soon as possible taking the US, the UK, Germany and Japan as examples after installing appropriate purifying facilities in line with the above benchmark. Above all, selecting a proper oil purifier is the most important process. Management standard of industrial lubrication

Infinitesimal metal substance oxidizes oil and becomes insoluble sludge in a status of resin. Sludge causes various hydraulic, lubricating troubles such as valve malfunction, weak heat exchange by attaching to oil cooler, oil viscosity decrease by oil temperature rise, lubricating error, oil leakage. Foreign substances in oil problem More problem caused by oxidized sludge Valve malfunction / Pump malfunction / Frequent strainer replacement / Pump cavitation rise / Oil temperature increase / Maintenance work loss Sludge is the cancer in the oil. Oxidized substance becomes Before After ZD treatment dangerous factors in oil. Above pictures well mirrors the fact that sludge can be cancer in oil. Operators easily neglect the potential problems that may occur in the near future, as no accidents happen at the moment. In the meantime, causes of trouble are in progress.
