Product Description

Low Vacuum Dehydration Machine

Low Vacuum Dehydration (LVDH) Machine.

Model: LVDH - 50 and LVDH -100.


Water in oil either free water or dissolved

Water, as well as dissolved Gases.

Method of Removing Water from Oil.

Centrifuge and Condensation methods typically only remove free water.

LVDH can remove both free and dissolved water from the oil as well as dissolved gases such as ammonia and hydrogen Sulphide.

Type of Oil

Turbine oil; Hydraulic oil ; Lubricant Oil ; Gear oil:

In above Oil, If water Mixed up, LVDH can be used for removing water from the Oil.

Function of water in oil

Destruction corroding machine Parts.

Reducing bearing life.

Water depletes anti rust & anti Oxidation

additives in Oil.

Depletion of additives.

Reduction in Lubricity.

Increased in acidity of Oil.

Accelerated aging of Components.


Power Generation and Hydro Power Plant.

Bearing Lubrication systems.

Hot Press in plywood Industries.

Pulp, Cotton, Sugar and Paper Plants.


Oil is indirect heated for 55 - 65 centigrade and reaching to Vacuum Chamber and moisture, water, air, gases are condensed and remove in form of vapor and are removed by the vacuum pump. The purified oil is drained from the rector chamber to the system/oil Tank.

LVDH is ensuring that there is no Aeration, No Burning of oil, No oxidation. Thus restoring oil to its Original Properties.


LVDH removes 100% of free water and free gases. LVDH removes 90% of dissolved water and dissolved gases. Menless Operation.

Pollution free process as no chemical reaction involved. After cleaning, Water content is below 250ppm. Even in New oil, water content permissible limits up to 350ppm.

Benefits of LDVH

Works on higher temp of 80 Centigrade.

Because of Centrifuge action, Aeration will take place.

Dissolved water and dissolved water gas can be not removed.

Machine cost is higher.

Wear & Tear is higher.

Operation cost is higher.

Man power is require on continuous attendance.

Works on 55-65 Centigrade under Vacuum.

No Aeration.

Dissolved water and Dissolved gas can be removed Up to 90 %.

LDVH Cost is lower. No wear & tear, higher Life of Gear & Vacuum Pump. It can be run on line with continuous manpower attendance.

No additive Depletion.

No Oxidation process.

Water content is below 250ppm.

User friendly.
