LVDH Machine Manufacturers in India
As experienced LVDH machine Manufacturers in India, we design and supply low vacuum dehydration units engineered to handle transformer oil, turbine oil, gearbox oil, and hydraulic fluid across continuous, multi shift industrial operations. Our team works with customers to size the right unit based on oil volume, moisture content, and the type of oil dehydration machine required for the application.
What is LVDH Machine
A LVDH machine, short for low vacuum dehydration machine, is a vacuum oil purifier that removes water present in oil in all three of its forms: free, emulsified, and dissolved. Unlike a centrifugal oil filter, which separates contaminants by density, a low vacuum dehydration unit uses low temperature vacuum distillation to vaporize moisture out of the oil while leaving the oil's chemical properties intact.
This makes the LVDH machine especially valuable for transformer oil dehydration, turbine oil dehydration, and gearbox oil dehydration, wherever water contamination threatens the reliability of Industrial Machinery and insulation strength.
Working Principle LVDH Machine
The working principle of a low vacuum dehydration system answers the common question, how does LVDH remove water from oil, through the following steps.
- Step 1: Contaminated Oil Entry: Contaminated oil is drawn into the vacuum dehydration unit through an inlet line under controlled vacuum pressure.
- Step 2: Controlled Heating: The oil passes through a low watt density heater, where it is gently heated to an optimum temperature, generally kept below 60 degrees Celsius to avoid oxidation.
- Step 3: Vacuum Distillation: Heated oil enters a distillation column where it is dispersed into a thin film under vacuum, increasing surface area and allowing moisture to evaporate.
- Step 4: Vapour Extraction: The vapourised water and dissolved gases are drawn off through a condenser by the vacuum pump.
- Step 5: Final Filtration: Dehydrated oil collects at the base of the column and is pumped out through a final particulate filter before returning clean, dry oil to the system.
- Step 6: Consistent Low Temperature Operation: Because the process runs at low temperature under vacuum, it directly answers how to remove water from transformer oil and how to remove water from turbine oil without degrading the oil in the process, something a simple heater based dehydration oil filtration machine cannot guarantee.
Types LVDH Machine
We manufacture a range of low vacuum dehydration equipment to suit different industrial requirements:
- Low Vacuum Dehydration Machine: The standard vacuum dehydration unit for continuous moisture removal from lubricating and hydraulic oils.
- Low Vacuum Dehydration and Degassification Unit: Combines moisture removal with a vacuum degasser function to strip dissolved gases along with water.
- Transformer Oil Dehydration Machine: A dedicated LVDH configuration built for transformer oil, where insulation strength depends on low moisture content.
- Turbine Oil Dehydration Machine: Suited for steam and gas turbine lubrication systems requiring continuous online dehydration.
- Gearbox Oil Dehydration Machine: Removes moisture from gearbox lubricant to prevent water related wear on gears and bearings.
- Hydraulic Oil Dehydration Unit: Designed for hydraulic systems where water ingress is common and needs continuous treatment.
- Vacuum Oil Filter Machine: Combines vacuum dehydration with particulate filtration in a single pass, often paired with our Tank Mounted Centrifugal Oil Filter range for complete oil conditioning.
- Portable LVDH Machine: A mobile low vacuum dehydration unit that can be moved between machines or storage tanks, similar in convenience to our Portable Centrifugal Oil Filter range.

When comparing LVDH vs centrifugal oil filter, the difference lies in what each technology targets. A centrifugal filter is built to separate solid contaminants by density, while a low vacuum dehydration machine is purpose built for moisture removal, including dissolved water that a centrifuge cannot fully address. Many industrial plants use both technologies together, pairing an LVDH unit with a Centrifugal Oil Filtration System for complete oil conditioning.

FAQs
A low vacuum dehydration machine, or LVDH machine, removes water and dissolved gases from industrial oil using low temperature vacuum distillation, without the oxidation risk of conventional heating.
Oil is heated gently under vacuum and dispersed into a thin film, causing moisture to vaporize. The vapour is drawn off through a condenser, leaving dry, clean oil behind.
A centrifugal filter separates solid contaminants by density, while an LVDH machine is designed specifically to remove free, emulsified, and dissolved water from oil.
Yes, unlike many filtration methods that only address free or emulsified water, a properly sized LVDH machine can also remove dissolved water from oil.
Cost depends on flow rate, tank capacity, and the specific application, whether transformer, turbine, or hydraulic oil. Contact us for a quote suited to your requirement.
