Vacuum Dehydration

Water Contamination in Hydraulic and Lubrication Systems

Water is one of the most common and significant contaminants in hydraulic and lubricating fluid systems. It is also one of the most damaging contaminants, especially in lower temperatures. Hydraulic fluids have less ability to hold moisture as the freezing point of water is reached. As the temperature decreases below the freezing point, ice crystals can form, adversely affecting the function of the entire system.

Water Contamination Problems:
  • Corrosion
  • Fluid breakdown
  • Reduction of lubricating properties
  • Additive precipitation
  • Oil oxidation
  • Reduced dielectric strength
  • Abrasive wear in hydraulic components
What is the best option for removing water from my system?

“The PVS Series Vacuum Dehydrator is the only proven & reliable method for removing both particulates & moisture from your hydraulic fluids.”

Vacuum Dehydration

Vacuum dehydration is most often the recommended solution for water removal from hydraulic fluids and lubricants because of its overall effectiveness and the minimal impact on fluid properties.

What is Vacuum Dehydration?

Vacuum dehydration is the total water removal from a hydraulic or lubricating fluid system using a combination of heat and vacuum. Raising the temperature while drawing a vacuum causes the water to convert to water vapor, which is drawn out by a vacuum pump. The water-free oil is then passed back into the system.

A Better Solution – PVS Vacuum Dehydrator

Hydradyne employs the Parker PVS Series, Portable Purification System vacuum dehydrator, which is one of the best machines on the market. These portable and durable systems allow us the ability to come to you and purify your system’s oil onsite, even in the most demanding environments. Using a combination of heat, vacuum, and filtration, these machines remove both particulates and moisture, returning your hydraulic fluids to their original state.

PVS Operation Breakdown

Contaminated oil is drawn into the Parker PVS Series Portable Purification System by a vacuum. The contaminated oil is then subjected to optimum vacuum, temperature, and increased surface area exposure. The optimum temperature is achieved using an in-line, low watt density heater. Afterward, the oil enters the distillation column, where it is exposed to the vacuum through the use of special dispersal elements, achieving the increased surface area exposure. This process converts water into water vapor, which is then drawn through the condenser by the vacuum pump.

The water-free oil falls to the bottom of the distillation 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 then back into the system.

Features & Benefits of the PVS System:

  • Portable and durable, allowing us the ability to come to you
  • Designed for 24/7 operation, increasing system operation time
  • Allows oil to heat quickly, removing water more quickly, and saving time
  • Real-time water content indication in % saturation, providing visual confirmation
  • You are able to view process, providing visual verification of water removal
  • Desiccant breather insures dry, clean intake air, providing more efficient operation
  • Flexibility with various fluid viscosities or consistencies, providing greater efficiency in removing moisture

Applications:

  • Hydraulic Systems
  • Lubrication Systems
  • Turbine Oil
  • Transformer Oil
  • New Oil (oil storage)
  • Seal Oil
  • Explosion Proof Environments
