Purifiner Introduction
This system could be of great value to your operations. As we all know, breakdowns can be expensive, especially during operations. What fewer people know is that oil contamination is estimated to be responsible for around 75 to 80% of all breakdowns in hydraulic and other mechanical systems. The Purifiner bypass oil filtration system can solve all normal oil contamination issues. The Purifiner is a low cost yet highly efficient unit, which operates as an integral part of a system. It is currently in use protecting 550 hydraulic and mechanical systems globally.
Below are links to the Purifiner brochure and Q & A sheet. My contact details are at the end of the introduction. There are also some links to web based details.
Introduction:
Seven main features and advantages of this bypass cleaning system:
 Filtration of solids down to 1 micron - Particle counts at these levels mean there are no detrimental effects caused by particles, even in control systems.
 Purifiner removes water, the next most damaging pollutant, down to 100 parts per million. It does this without the need for water absorption filters, centrifuges, etc. Most other systems rely on this type of water removal apparatus.
Acids are removed from oils as well as the gases that when mixed with water, create acid. Most other systems do not address acids.
 Purifiner is small and portable. It weighs just 45 Kg and is approximately 500 mm cubed in size. This enables one unit to be used for several pieces of equipment. Although Purifiner is portable, most companies install the Purifiner in a fixed position working 24/7 to maintain oil standards continuously on major pieces of equipment like bow thrusters and central hydraulic plant.
 Purifiner has low power consumption at about 1.2 KW at 220/230 V and 50/60 Hz. It is capable of maintaining high oil standards in systems with a capacity of either 2,000 litres or 4,000 litres of oil depending on Purifier model. For larger installations the units can be duplicated.
 Depending on the unit type, Purifiner can be used on pressurised and non systems. Oil can be returned after cleaning to systems with up to 8 bar of back pressure.
 If oil is kept pure it will last much longer. Some owners report their oil is still good after periods up to 18 times longer than when full flow filters alone were used. This not only increases service intervals but is very good for the environment. Oil changes are far less frequent. There are also the cost savings involved with those oil changes to be considered.
There are three versions of Purifiner available. All are built on a stainless steel frame. All have pre-heaters, pre-filters, controls, warning lamps, etc.
 The Gravity Return system. This type has only a suction pump. Return is by gravity. This unit must be mounted above the oil reservoir. It is often used to clean new oil before it is added to a system. This is required for sensitive systems such as Azipods because new oil is often so polluted.
 The Fully Pumped system, (by far the most popular), has both suction and return pumps. It is capable of returning oil with up to an 8 Bar back pressure. It can be mounted above or below the oil reservoir.
 The Fully Pumped Purifiner Twin - Same as the fully pumped system but double the capacity / cleaning rate.
The Purifiner is not the same as any other system. It has a world patent and there are several features that make it unique both in design and approach. The device is meant to become part of a system running 24/7. Because of its size and weight, it can also be used as a portable device. At around 600 litres per 24 hours, it slowly but continuously removes the pollutants that are created in the machinery as well as the pollutants that are found in new oil. Continuous oil maintenance means oil is kept pure and its useful life greatly extended.
Here are some distinct design features that makes it different from other systems:
 Purifiner uses a filter made of pure unbleached cotton. One reason for this is that the filtering medium chemically attracts and retains free acids from the oil. High acid counts can lead to internal corrosion, etching and break down of additives. Acid removal is not a normally addressed by most oil cleaning systems.
 Purifiner removes solid particles down to 1 mu. Most other bypass systems filter down to around 5 mu.
 To remove water, the Purifiner uses thin film evaporation, not centrifuges or water absorption filters. This thin film evaporation process removes free water down to 100 p.p.m. This ensures that only pure lubricants are lubricating the sensitive bearing and sealing surfaces. It also ensures that sludge build up due to emulsification is stopped. Oily water sludge is known to cause many problems in sensitive hydraulic control systems and early failure of bearings. Free water also combines with certain gases to create acid that leads to internal corrosion. Because no filters are used to remove water and gases, there are no expenses relating to these. This translates into more savings for the end user.
 Purifiner removes harmful gases during the thin film evaporation process. As mentioned earlier. These gases combine with free water to create acids like sulphuric acid. Using thin film evaporation technology on a continuous basis means with both the water and the gases removed, acid is not manufactured in the oil. Other systems do not normally address this harmful gas issue.
