Klarol is a product designed and developed in Germany. The product has been field tested for crucial oil characteristics (TAN, TBN, NAS, Viscosity, Moisture content, Flash point etc) under tough conditions in India on a variety of applications.

Klarol's strength lies in the simplicity of its technology. Klarol cleans oil in two stages. In the first stage, oil under pressure passes through the Klarol replaceable filter made of compressed cellulose. Here the solid contaminants like carbon, dust, metals, varnish, gum etc are removed by the process of absorbtion and then adsorbtion.

Klarol removes solid contamination upto 1 micron and hence manages to keep the oil at the extremely clean level of NAS 5/6.

In the second stage, the oil passes in the form of a thin film through the unique Klarol evaporation chamber under controlled temperature conditions. Liquid contaminants like water, coolant and fuel are evaporated here by "thin film evaporation theory" without heating the oil and evaporation products are vented out of the chamber.
