Principle

Unlike existing conventional filters, ZD series utilizes the principle of electrostatic ion. Ascontaminated oil passes through the electrode, equipped with an electrostatic dielectric, variouskinds of impurities in the oil are removed and attached to the dust collector. It is circulatingpurification 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 firstoperation and separate moisture (20,000 ppm) secondly.

Normal filters are able to purify the particle size of 5 micron to the utmost. However, ZD seriescollects and removes 0.02 micron impurities with tertiary electrostatic ion system. As pre-maintenance equipment, ZD series will be the ACE in your factory since they prevent oil oxidationand maintain proper oil viscosity so as to supply clean oil.

Structure

By utilizing ZD oil purifier, customers will say goodbye tofinancial burden incurred by expensive oil price andquantities of waste oil. Zedal guarantees its prominenteconomical efficiency.

Features and Effects

1.Conventional filter type purifiers were unable to remove foreign substances below 5 micron, whereasZD series eliminates extremely infinitesimal particles of pollutant (below NAS 7 level) and reduces themto clean oil. As a result, various impurities that speed oil oxidation, below 5 micron, are eliminated inadvance. According to the statistics, the oil purifier could not only prolong the service life of oil but saveoil and electricity by 90% and 15% respectively, reduce failure rate by 70%, and decrease machineabrasion. 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 reachmore than seven years.

4.In the process of filtration, oil does not generate bubble, and water separation could reach 20,000PPM. For filtering oil containing quantities of water, the static oil purifier is equipped with oil-waterseparator.

5.The circulation mode cleans pipes inside the machine and removes the oil (below 460cst with a 60cstcirculation 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 304 1300 MESH) couldbe used repeatedly after being cleaned with absorbents. The three-phase 220V 500W consumed powercould save electricity to a great extent.

Economic effects

Annual save of equipment maintenance expense could purchase a new oil purifier.

15-30% equipment maintenance expense,accounting for 1.3% of sales volume, could be saved.

Loss caused by the one hour halt ofthe equipment is equal to price of anew oil purifier.

Lubricant expense can be savedbelow 0.1% of sales volume.

Necessity of lubrication management

1.As the general development trend of modern industry is high performance, speediness, and ordinaryindustrial equipment is gradually shifting to the full automation. If accidental failure occurs in theequipment, the loss would cover not only maintenance but immeasurable losses incurred from the halt ofequipment.

2.Over 70% of mechanical failures are caused by improper lubrication management. It is estimated thatproper lubrication management brings considerable economic benefits, equivalent to about 4% of GNP ofthe 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 equipmentfor the purpose of preventing lubricating oil, prolonging oil service life, saving expenses, avoidingmechanical failure in advance, and decreasing the expenses caused by spare parts replacement andmaintenance. Thus, mechanical performance, productivity and quality could be guaranteed so as toreduce cost in enterprise operation.

4.Detailed implementation is as follows; firstly, to accurately check and analyze the management statusof each mechanical oil used in the factory; secondly, to set the standard for the pollutant use limit inaccordance with the mechanical performance and for the purpose of guaranteeing the managementbenchmark; thirdly, to execute the pollution management system as soon as possible taking the US, theUK, Germany and Japan as examples after installing appropriate purifying facilities in line with the abovebenchmark. Above all, selecting a proper oil purifier is the most important process.
