WHY DO WE NEED AN
ADDITIONAL OIL CLEANING
SYSTEM??

5. Machine Filters cannot remove contamination
smaller than clearances of critical components.

6. Machine Filters cannot remove water which can act as
a catalyst to increase acid value.

Amount of Oil Oxidation
(Nutralization Number)
1. Test oil - Turbine oil - viscosity 32cSt / 100 degrees F (37 degrees C)
2. Oil temperature 200 degrees F (93 degrees C)

8. Machine Filters cannot remove air which is a
destructive contaminant !
Symptoms of aeration in fluid include:
 Higher component noise levels.
 Erratic system performance.
 Premature pump failures.
 Increased fluid temperatures.
 Fluid viscosity changes.
 Loss of fluid lubricity properties.
 Oxidation of fluid.
Thermal degradation - Did you know that compressing an air bubble from
ambient pressure to 3,000 psi increases the bubble's temperature to more than 2,000
degrees F? This is hot enough to thermally degrade oil at the boundary contact between
the air and the bubble, which darkens the oil, sometimes giving it a sooty appearance,
and causes varnish to build up on component surfaces.

9. At higher oil pressures components require cleaner oils.

11. MACHINE FILTERS CANNOT STOP OIL DEGRADATION

12. Oil degradation can be the cause of numerous sources of potential
collateral damage to the machine that are described below:
Corrosion
Acid attacks component surfaces, causing pitting and surface degradation.
Varnishing
Polymers and oxides are other by-products of the oxidation process. Varnish deposits on servo,
proportional and other tight-clearance hydraulic valves result in sticking, which can slow or stop
operation.
Loss of Lubricity
Oxidation affects the physical properties of the oil, altering its flow and lubrication characteristics.
Foaming and Air Entrainment
The moment the base oil begins to degrade, the interfacial tension properties of the oil start to
decline. Interfacial tension (related to surface tension) is the physical property that describes the
ease with which oil separates from insoluble materials such as air and water.
In hydraulic systems, entrained air produces sponginess and loss of precision control, again due to
the air’s compressibility.
Filter Plugging
Varnish deposits and sludge can cause rapid filter depletion (a big cost on some machines).
Likewise, the entrainment of water due to poor demulsibility properties adversely influences the
filterability of the oil.

13. FOAMING IN HYDRAULIC OIL

14. IT IS THEREFORE IMPORTANT
THAT WE USE AN ADDITIONAL
OIL CLEANING SYSTEM WHICH
IS CAPABLE OF REMOVING
SOLID PARTICLES, WATER,
OXIDISED LIGHTER WEIGHT
MOLECULES OF OIL
& AIR AND GASES FROM
THE OIL IN USE.

15. KLAROL ---The Technology
 An oil cleaning device capable of removing solid,
water, oxidised lighter weight molecules of oil,
air & gaseous contaminants from any oil.
 Designed and developed in Germany.
 Field tested in India on a variety of applications.
 Tested by Indian Institute of Petroleum.
Clean oil ensures - NO MORE OIL CHANGE !

16. KLAROL----Benefits
 Ensures Super-Clean oil at all times.

Proportional Valves/Servo Valves, expensive pumps,
Hydrostatic bearings…etc
 Ensures better machine operation.
 Ensures more production and better product quality.
 Can increase oil life indefinitely.
 Reduces pollution.
 Economical to use and quick return on investment.
Clean oil increases machine life !

17. KLAROL—How Does It Super-Clean Oil
Klarol Cleans Oil In Two Stages.
Stage 1 Removes solid contamination by:
Depth filtration.
Electrostatic attraction.
Stage 2 Removes water, fuel, entrained air
and gases by evaporation.
Clean oil ensures more productivity !

18. How does Klarol clean contaminated oil
Outlet for water vapour,
air & gases, lower weight
cracked molecules of oil.

20. KLAROL---Applications.
 Klarol can be used to clean oil as a
mobile machine.
 Klarol can be installed directly on any
machine as a by-pass oil cleaning
unit.
Clean oil ensures better product quality !

42. Prevention better than cure !
Prevention of contamination is more cost-effective than
the cure.
Ensure the following always:
• Proper breathers to prevent contaminated air from entering reservoir.
• Well designed reservoirs to ensure settling of heavy particles & water to
be drained at intervals.
• Drum stored horizontally to prevent water ingress.
• Recycling of oil regularly or use it to prevent long-term degradation.
• Filtered oil going into and out of the reservoir.
