We have established ourselves as a renowned manufacturer, supplier and exporter of a vast array of Klarol Turbine Oil Purification Systems. Our products are manufactured using excellent quality components and spare parts that are procured from authentic vendors after scouring the market. All our products are highly appreciated by customers for their brilliant performance, durability and sturdy construction.

Technical Feasibility:

  • At the moment Turbine Oils are cleaned by centrifuges, which remove contamination and free water.
  • A centrifuge cannot remove emulsified water from turbine oils, which acts as a catalyst to increase oxidation, causes foaming in oils and reduces component life.
  • One of the major problems of continuous water presence in the oil is formation of varnish, which is a thin insoluble film deposit that is usually found on bearings and servo-valves.
  • It is a high molecular weight substance that is insoluble in oil.
  • Varnish insoluble are more than 75 percent soft contaminants that are less than 1 micron in size and are not measured by traditional particle counts.
  • Insoluble compounds have polar affinities and begin to migrate from the body of the base oil to machine surfaces.
  • The surfaces start to show a golden or dark brown color which then changes to darker gum layers that hardens into lacquer.
  • Varnish cannot be removed by a centrifuge. It can choke turbine oil filters, servo pencil filters, reduce bearing life, cause servo and directional valves to stick and fail and can even cause turbine shut-down.
  • Varnish’s propensity to attract dirt and solid particle contaminants increases component wear.
  • Varnish’s insulation effect causes loss of heat transfer in heat exchangers.


Working Principle:

  • Klarol cleans oil in two stages using three different methods.
  • In the first stage oil enters the depth filter to be cleaned by absorption.
  • All solid contaminants up to five microns are removed in this stage.
  • The oil then passes at a controlled flow rate into the Klarol evaporation chamber, which is heated to ensure a dry airspace. Controlling the flow of oil ensures formation of thin oil film in the evaporation chamber.
  • These conditions are ideal to evaporate moisture and lower oxidized molecules of oil, air & gases from the oil.
  • Purified oil then goes back into the parent tank.
  • The Klarol fibre glass depth filter removes insoluble contamination like sludge, varnish and particles smaller than a micron by absorption i.e. (attracting and trapping the contamination in its filtering medium) when oil is continuously cycled through Klarol
  • These systems are designed to remove contamination in stages and the continuous cycling of oil through it ensures that the smallest size contaminants are removed to provide super-clean oil in the parent machine.
  • Installing these machines on a turbine oil tank to continuously clean oil would help in maintaining the cleanliness level of oil at NAS 5 at all times.
  • These systems should be permanently installed on oil tanks, which supply oil to the turbine governing system.
