Low Vacuum Dehydration Machine (LVDH Machine)

KLEENOIL LOW VACUUM DEHYDRATION (LVDH) MACHINE

With the LVDH being the most cost friendly and reliable way to remove water from hydraulic oil, the machine is most suitable in situations where large amounts of water get emulsified into the oil.

  • Gearbox oils.
  • Compressor oils.
  • Steam Turbine Lube Systems.
  • Purifying Transformer oil.
  • Synthetic oils.
  • Easy to operate for an efficient method for continuous removal of moisture from oil.
  • No damage to oil and the unit offers dry, dehydrated oil.
  • Significantly reduced residence time with fast and efficient heat transfer.
  • Reduced pressure drop.
  • High evaporation ratios (> 95%).
  • Easy to clean/maintain equipment.
  • Ability to process materials that are sensitive to thermal degradation or prone to fouling and ability to process high-viscosity and high-solids materials.

PRINCIPLES OF OPERATION:

Contaminated oil is drawn into the Kleenoil Low Vacuum Dehydration machine by a vacuum of 700 millibars. The oil passes through the in-line low-watt density heater where the oil is heated to an optimum temperature of 66°C-70°C (depending on oil flash point capacity). The oil then enters the distillation column where it is exposed to the vacuum using special dispersal elements.
This increases the exposed surface area of the oil and converts the water to vapors form, which is then drawn through the condenser by the vacuum pump. The water-free oil falls to the bottom of the column and is removed by a heavy-duty lube oil pump. This pump forces the dry oil through a final particulate removal filter. Clean oil passes out of the unit, back to the reservoir – and into the system.

Form of WaterFree WaterEmulsified WaterDissolved Water
DescriptionWater content well above fluid saturation point. Water exists in the form of a completely separate layer with the oil.Water content above fluid saturation point. Water is emulsified with the oil, forming a cloudy mixture.Water content below fluid saturation point. Water is solubilized in the oil, resulting in a dean and normal looking lubricant.

  • Process flow rates upto 300 lpm.
  • No other utilities other than electricity are required (no costly water consumption).
  • Dry Running Claw Vacuum Pump – Pulls deeper vacuum than conventional vacuum pumps, dramatically increasing water extraction rates.
  • Requires virtually no maintenance – no vanes to wear out and no lubricating oil to become contaminated by a wet air stream

  • Removes water and dissolved gases from oil
  • water reduction below 300 ppm
  • No oil quality damaged since temperature ranges between 45 to 60 deg.
  • Plug and Play
  • Run both offline and online
