Low Vacuum Dehydration Machine (lvdh machine)

Low Vacuum Dehydration Machine (lvdh machine)

The Low Vacuum Dehydration (LVDH Machine ) technique is mainly used for separating moisture content from the oil which is present in three forms:
a) Dissolved Form
b) Emulsified Form
C) Free form

  • Very fast and highly effective water removing device, meant for high duty applications.
  • Easy full automatic operation.
  • Removes water, moisture and air bubbles: dissolved water: 80%, free water: 100%, air bubbles: 100%
  • Viscosity range from 10 ~ 600 cSt.
  • Oil temperature from 15°C ~ 60°C.
  • On demand, all systems can be supplied by customer requirement.

Working Principle of Low Vacuum Dehydration machine :

The heating of hydraulic oil is performed indirectly and then that is poured into a vacuum chamber where it is scattered into a very thin layer of film thereafter it vaporizes & gets dissolved with gases at low temperature. How do separate water from oil? Now both air and gases that are derived from the previous process are now left to condense so that it gets separated from the oil. Our ultimate goal of heating oil indirectly at low temperature is to ensure that there is no burn off, hence no oxidation and no additional depletion of oil.

WORKING PRINCIPLE OF ELECTROSTATIC MACHINE

Destiny International  Sump Cleaner removes sludge, metal chips & swarf from Coolant / Oil tanks & filters it via reusable steel mesh filter. The System Works on the Principle of Vacuum Suction. A powerful vacuum blower creates vacuum in the tank of the unit, which sucks in coolant, metal chips Swarf etc, passing it thru mesh basket. Contamination gets collected in the basket & clean coolant flows through to the tank of the unit. A centrifugal delivery pump delivers back the clean coolant.

Comparative analysis of Vacuum Dehydration With Centrifugal water removals:

Centrifuging

Vacuum Dehydration

Heating oil to Approximately between 70 to 80°C is required to efficiently extract water

Whereas in LVDH technology, the Water is removed from oil even less than < 55°C.

Heating oil depletes additives.

No additive depletion.

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

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

Somewhat cleans low molecular weight oxidized oil fraction

Easily removes low molecular weight oxidized oil fraction

Cannot remove emulsified water. Gear pumps used in centrifuging 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.

Centrifugal systems do not clean any dissolved gas

Clears the dissolved gasses very easily

Many high speed moving parts requiring frequent maintenance

Only two pumps. Vacuum & discharge & slow moving parts.

 

Automatic water discharge.
