What exactly does our Technology do?
On what scientific fact is our Technology based?
The conclusion drawn form Technologic papers of the US Bureau of Standards, US Department of Commerce, is that it has been found that oils do not wear out mechanically, and may be used over and over again. Quote include:
- “A mineral oil is usually just as good after use as before, apart from the impurities, which are removed by filtering.”
- “The apparent result of all these different tests is that a used oil, receive in good condition and filtered with care to rid it of the material which it may contain in suspension, preserves its different properties almost intact.”
How exactly does our Technology work?
Figure below shows a cut away diagram of our Purifiner filter unit. All units consist of two main areas of operation through which the oil must flow – a filter element for the retention of solid and acidic contaminants, and an evaporation chamber to remove liquid and gaseous contaminants. The filter element consists of long strand unbleached cotton, capable of removing solid contaminants down to 1 micron. Contaminants below this size are not a wear factor in engines or equipment – a claim widely accepted by engine manufacturers, which is supported by SAE 660081:
“Filtering used oil through a 5 micron filter did not significantly reduce wear rate; however, when the used oil was filtered through a 1 micron filter, there was a significant reduction.”
Removal of particles down to this very small size also keeps engines free from sludge. Most reasonable quality oils will hold sludge particles in suspension up to 2-3 microns, above which they start to fall out and “dirty” the engine, this can be seen when examining the sump deposits of a used engine. With our Oil Purifiner technology, this phenomenon is eliminated. The engine can, therefore, operate in a cleaner environment, the extent of which is clearly evident when an engine is stripped down for rebuild or repair.
Unprocessed cotton is utilized as the filter medium because of its natural ability to retain acid contaminants – pure cellulose is not as effective as untreated cotton. It is necessary to have a slow flow rate through the filter element, not only for solid particle retention, but also to allow the chemical reaction between the cotton and acids to take place.
Oils designed for use in engines come with certain additives, for example zinc, calcium and magnesium. Calcium & magnesium are alkaline additives used to neutralize acids, and their presence is reflected in the Total Base Number (TBN). Zinc is an antioxidant, the beneficial effects of which are reflected in the level of the Total Acid Number (TAN). During normal engine operation, these additives are depleted. Wiramas Oil Purifiner offer a choice of two types of filter element per unit, one containing additive pellet for engine applications to replenish the zinc and magnesium used during a service internal, and the other a standard filter without pellets, for non engine applications.
Prevention is better that cure
Our Purifiner filter unit removes harmful solid, liquid and gaseous contaminants, but also goes a stage further in that it actually prevents the formation of some of the contaminants in the first place. This is illustrated with sulphuric acid.
Sulphuric acid is formed in engine oil as a result of the reaction of sulphur dioxide and water, both of which are by- products of combustion. Water also contaminates the oil due to the formation of condensation as the engine cools after shut down. The Wiramas Oil Purifiner system evaporates the sulphur dioxide and water due to the “Thin Film Evaporation Effect” in the heated chamber before the reaction to produce sulphuric acid takes place. As a result, the acid is not allowed to harm the oil, the additives are not depleted and the viscosity is not affected.
There are many benefits of Wiramas Oil Purifiner technology, which can be summarized as follows:
Significantly reduces operating expenses by:
- Greatly extending oil change intervals
- Significantly reducing new oil purchases
- Increasing engine efficiency, thereby improving fuel consumption
- Reducing down-time, thereby improving bottom line profits
- Reducing maintenance costs
Significantly reduces maintenance costs by:
- Removing sludge that wears engine and equipment parts
- Preventing the formation of acids which corrode engine and equipment parts
- Removing fuel dilution
- Preventing the formation of water-oil emulsion
- Reducing waste oil handling and disposal costs
- Having no maintenance requirement (the Purifiner technology has no moving parts)
Significantly reduces capital expenditure by:
- Extending engine and equipment life and time before rebuild
- Offering a rapid payback period
Significantly enhances the environment by:
- Reducing environmental pollution by decreasing toxic waste disposal and storage
- Minimizing problem of filter element disposal
In addition, our Purifiner technology:
- Protects hydraulic systems by reducing pitting and scoring of pumps, control valves and cylinders
- Cannot harm any engine or equipment
