The Parker PVS Series Portable Purification System features automatic operation and ease of maintenance. This vacuum dehydrator is conveniently portable, and able to purify a system's oil on-site, even in the most demanding environments.

Water is one of the most common contaminants in a fluid system and one of the most damaging. When water contaminates a system, it can cause many serious problems such as: corrosion, fluid breakdown, reduction of lubricating properties, additive precipitation, oil oxidation, reduced dielectric strength, and abrasive wear in hydraulic components.

Whether dissolved water (water which is absorbed into the oil) or free water (occurring when oil is too saturated* to hold any more water), solid particulate, or air/gasses, contaminated oil can be purified on-site using Parker's PVS Series Portable Purification System.

* Please Note that Temperature and Fluid type determines the saturation point for your

system (Please Refer to Brochure).

Maintaining a hydraulic system's oil cleanliness level will increase the life of the critical wear components, and reduce system downtime. Portable purification units are ideal for systems in applications demanding on-site decontamination. With several models to choose from, the Parker PVS Series is an ideal solution for many hydraulic system's needs.

Principles of Operation:

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.

Why PVS (Vacuum Dehydration) Techonology Out-performs Other Technologies?

• Centrifuge units – Removes free water only; has difficulty breaking stable emulsions; larger envelope dimensions but lower flows; higher initial and operating costs.

• Desiccant units – Have limited water removal capability due to absorbing material; only removes air ingressed particles; expensive compared to the volume of water removed.

• Coalescer units – Removes free water only; has difficulty breaking stable emulsions; does not work well in viscous fluids (>100 sus); much larger in size compared to PVS.
