OilLife Bypass Oil Filter Systems

IPU’s OilLife bypass oil filter (formerly known as EOLS: Extended OilLife System) is a kidney loop filtration system that enhances engine lubrication beyond the capabilities of traditional oil filters. Working in parallel with standard oil filtration, the OilLife system uses both filtration and evaporation to remove solid, chemical and gaseous contaminants from oils and hydraulic fluids. When combined with IPU’s OilAlert oil condition sensors, you can extend oil life and enjoy the security of realtime reporting of oil quality.

About 80% of engine failures can be attributed to contaminated oil impairing engine lubrication. In hydraulic systems, the figure is even higher with around 90% of breakdowns being caused by oil-borne contaminants. Traditional full-flow filters usually struggle to remove small wear particles and are unable to remove gaseous contamination.

How a bypass oil filter works

How bypass oil filters work: a bypass oil filter adds extra protection to engines working in critical or contaminated environments.

IPU’s OilLife system is suitable for engine, hydraulic, transmission and compressor oils and the results and benefits are impressive:

  • Oil drain intervals extended by at least 4 times.
  • Reduced wear and damage to the engine.
  • Reduced oil usage and disposal cost.
  • Minimised filter replacement and ongoing consumable costs.
  • Reduced likelihood of unpredictable maintenance.

IPU’s OilLife improves engine lubrication. The state-of-the-art dual filtration and slow-venting evaporation systems combine to remove all forms of contamination. Contamination can be traced to a number of root causes such as liquid acids, sludge, soot, abrasive particles and fuel dilution. IPU’s OilLife system removes at least 98.4% of solid contaminants down to 1 micron in a single pass.

How OilLife bypass oil filters work

IPU’s OilLife system combines the dual-action process of filtration and evaporation to remove all oil-based contaminants.Contaminated oil  is transferred through a small metering jet under normal engine oil pressure supplied by the engine’s oil pump.

Oil is passed through long-strand, protein-rich cotton, a highly efficient filtration medium capable of absolute filtration down to 1 micron. Acidic contaminants react with the protein-rich cotton, removing them completely from the oil. Once filtered, the oil enters the heated evaporation chamber where liquid contaminants and gases are evaporated and vented to the atmosphere.

The OilLife unit features a unique patented diffuser plate design which provides a large heated surface area relative to the volume of oil. This allows the thin film evaporation effect to remove all precursors to acid formation. After the contaminants are removed, the clean oil is gravity-fed back to the engine oil sump. For hydraulic applications such as bow thrusters, the system incorporates its own electrically-powered pump to provide oil circulation through the cleaning system and back to the hydraulic tank.

 

Why is 1-micron filtration important?

Particulates under one micron in size will not have an abrasive effect in engine or hydraulic oil. Most quality engine and hydraulic oils will keep solid contaminants under 4 microns (such as sludge) in suspension.

However, the danger is that smaller particles will combine, fall out of suspension and collect in the engine oil sump. This results in a considerable drop in performance in the engine and hydraulic system.

Competitive comparison

IPU’s OilLife removes at least 98.4% of solid contaminants down to 1 micron in a single pass. OilLife prevents the formation of the acids which hamper an oil’s ability to lubricate, seal and cool the engine. The system’s dual action of filtration and thin film evaporation is five times more effective than alternative diffuser plate designs.

OilLife is a versatile and effective solution for use across a wide range of applications including transmission fluids, hydraulic oils, compressor and engine oils.

 

OilLife benefits

  • Greater cost savings – lower unit cost, lower consumption in filter media and 2 stage disposal process.
  • Suitable for a wide range of high and medium speed engines.
  • For use with multiple applications.

 

Evaporation process

  • Unique thin film evaporation chamber design.
  • Heating element.
  • Thin film evaporation effect removes water, diesel fuel (light hydrocarbons) and sulphur dioxide / trioxide.

 

Filtration process

  • Long-strand, unbleached, unprocessed cotton.
  • Solid contaminants filtered down to 1 micron.
  • Slow flow rate (40 litres per hour) in order to retain solid contaminants and allow chemical reaction with cotton (acid retention).
  • Prevents build up of sludge.

 

Alternative systems

Centrifuge models are partially effective at removing sub 5-micron contaminants

  • Most alternative by-pass systems are application specific.
  • Higher unit cost and up to six stage disposal process.
  • Alternative models cover a lower application range.
