Water in oil leaves a trail of destruction corroding machine parts, reducing bearing life, leading to

catastrophic breakdown.

Water depletes anti rust & anti oxidation additives in oil. It combines with gases such as ammonia and

hydrogen sulphide - perpetuating the corrosion process.

A number of methods are used for removing water from oil, like centrifuging and coalescers. The most

popular method to remove water is centrifuging.

Centrifuging however, cannot/does not efficiently remove water from oil, as explained in the

comparativechart.

PRINCIPLE

Oil is indirectly heated and fed into a vacuum chamber where it is dispersed into a thin film to vaporise

water and dissolved gases at low temperature.

The air and gases that evolve are condensed and removed from oil. Ultimate water removal through re

circulation is zero percent water content or 5O% below saturation level. Soluble gases and air are also

removed to 50% of saturation level. Indirectly heating oil at low temperature ensures there is no burn off,

no oxidation and no additive depletion.

Cracked low molecular weight oil, which is a by-product of the oil oxidation process, which accumulates in

the hydraulic or lubrication fluid, accumulates in Oil.

The LVDH is the only system, which can remove, cracked oil, thus restoring oil to its original properties.

The LVDH unit removes water/moisture to below 50% of the saturation point in oil at low temperature.

(44-600C) and finds application in: Hydraulic oils Turbine oils . Compressor oils

Vacuum pump and compressor seal oils Gear oils Dehydration before blending different oils.

Comparison With Centrifuge for water removal

Centrifuging Vacuum Dehydration

Must heat oil to 80 C for efficient removal of impurities

& water

Water is removed from oil below 55 C.

Heating oil depletes additives. No additive depletion.

Must be used off-line. All related machinery must bestopped to drain oil into barrels / tanks for cleaning.

Can be used on-line, is therefore user-friendly.

Aerates oil, thus increasing net oxygen supply &depleting anti-oxidation additive.

No aeration. No additive depletion.

Cannot remove emulsified water. Gear pumps used incentrifuging increase emulsification. ;

Easy & total removal of free & emulsified water /moisture.

Cannot remove low molecular weight oxidised oil

fraction

Removes

Cannot remove dissolved gases like Ammonia /Nitrogen.

Removes

Cannot remove solid impurities below 10 micron,efficiently.

In conjunction with Electrostatic-oil Cleaners,removal efficiency is better than 0.01 micron.

High energy consumption. Low

Many high speed moving parts requiring frequentmaintenance

Only two pumps. Vacuum & discharge & slowmoving parts.

Automatic water discharge
