How Clean is Clean Enough?

- How Clean is Clean Enough?

How clean is clean enough? What if we told you that several of our customers have reduced the amount of oil related maintenance problems by 70%! While doing so, they have also decreased the amount of power required to operate their equipment!

This is in addition to the other, more obvious benefits of extremely clean oil. The fact is that oil cannot be too clean, but it surely can be too dirty. Only in the past few years have removal of particles smaller than 5 microns (half the size of a red blood cell) been considered as part of an oil cleanliness program.

The real small contaminants, which are measured in angstroms (one one-hundred millionth of a centimeter) are the problem children, causing restriction problems, and are the source of tars and varnishes in an oil system.

How about the larger sized particles? Well, contaminants in the 1 micron size and larger range do rapid damage in areas of close tolerance like gear pumps, hydraulic cylinders, servos, bearings and spool valves. When these large particles enter moving components, they break off machined surfaces and cause more particles.

There are several university studies, which document the damage caused by these particulates and the life extension achieved by having extremely clean oil. The long-term benefits of continuous filtration with Electrostatics, as the contaminants are purged from the system, will become evident through reduced downtime and maintenance expenditures, extended machine life and vastly improved (3 to 5 times) fluid life.

Coupled with a water absorber (standard equipment with ASL Systems) this product will protect the lifeblood of the oil system from three of the five major factors that contribute to fluid degradation.

Filtration FAQs

- I note that the Electrostatic Cells are listed as “exchange.” How does this exchange work?

As stated previously, the life span of an Electrostatic Cell is approximately one year of 24/7 operation, or 8760 operating hours. At this point, the Electrostatic Cell should be replaced with a new one. ASL re-manufactures thousands of Electrostatic Cells each year, so fresh cells are always on the shelf.

In order to keep costs as low as possible, ASL needs your spent Electrostatic Cell core returned. Each returned core is completely disassembled, cleaned and inspected. The internal components are disposed of, and only the tube and end caps are re-used, provided they meet stringent requirements. All internal components are replaced with new parts; the Cell is tested, labeled and packaged.

As your Electrostatic Cell nears the 8760-hour point, a fresh cell can be shipped to you in advance. After installing the new Cell, place the used cell in the shipping container the new cell arrived in, and return it to ASL. We will allow 30 days to receive your spent Cell, before reminding you. Spent Cells that are not returned are subject to a core charge.

- Why are your Electrostatic Systems better than others on the market?

Quite frankly, there are several reasons.

- What if my fluid is more conductive than common hydraulic fluid, for example?

The Unique design of our Electrostatic Cell is such that it can be easily manufactured in a variety of positive to negative “spacing” to accommodate many different fluid conductivity levels. Hydraulic Fluid such as DTE-25, for example, has almost no conductivity, so Electrostatic Cells employed on this fluid have close positive to negative spacing.

Fluid such as Air Conditioning compressor oil has higher conductivity, so the Electrostatic Cell for these applications is manufactured with somewhat wider positive to negative spacing. Phosphate Ester “fireproof” hydraulic fluids, which become more conductive as fluid temperature rises, require an Electrostatic Cell with even wider spacing.

Note that there is no extra charge for any Electrostatic Cell configuration.

- I have always heard that Electrostatic Systems were expensive?

While high procurement costs may exist from some of our competitors, ASL Electrostatic Fluid Purification Systems are the most cost effective systems on the market today. ASL system prices rival conventional off-line filtration systems, and, more often than not, can cost less than the fluid in your reservoir. Really!

- Electrostatic systems use High Voltage DC, but how high is it?

Our Electrostatic Systems use 15,000 VDC @1 milliamp. Research has shown that 15,000 volts is optimum for fluid filtration. However, with DC voltages in this area, the water content must be in the 300 to 500 ppm (KF) area to be effective without shorting out.

This is one of the reasons that ASL incorporates a water absorber pre-filter to remove free and emulsified water from your fluid prior to the Electrostatic Cell.

Other Electrostatic system manufacturers use much lower DC voltage in their Electrostatic chambers to tolerate this conductivity, but performance and efficiency.
