Equipment
(Specified)
Highest Water Extraction Rates in the Industry
Alarm indicators with automated system shut-off – enables unattended operation for 24/7 service
Permanent dispersion media – provides maximum surface area for high water extraction rates; eliminates need for costly coalescer element change-out
Dry running “claw” style vacuum pump – very durable and reliable in wet oil applications; requires very little maintenance while providing long life
Phase reversal switch
Digital temperature controller – enables operator to set optimal oil temperature
Variable frequency drive – gives system versatility across a wide range of applications
Inlet solenoid valve – for fail-safe isolation
High Performance Purification
The harmful effects of water, entrained gases particulate, and varnish contamination in lubrication and hydraulic oils have been well documented. By removing all water contamination and entrained gases, VDOPS helps maintain the oil’s original viscosity, ensuring its optimal performance and extending its life as a lubricant.
50 GPM NEMA 4
5 GPM NEMA 7
3 GPM NEMA 4
VDOPS units are available in a wide range of configurations and flow rates to adequately handle virtually any application.
"OFS has been a preferred supplier of filtration equipment and vacuum dehydrators for the Chevron ISOCLEAN® Program now for five years, and not only does their equipment give unmatched performance in terms of water and particulate removal, their company gives us the kind of customer support, customized quick response, and service that we need in today’s fast-paced and competitive business environment."

Because of its unique vacuum tower design and high CFM vacuum pump, our Vacuum Dehydration Oil Purification System (VDOPS) gives the highest water extraction rates available in the industry today. We build Vacuum Dehydration Oil Purification Systems (VDOPS) in a wide range of process flow rates for optimal performance on almost any application. A general rule of thumb to use is 1 GPM flow rate for every 100 gallons of reservoir capacity, so we build VDOPS units in the following process flow rates: 1 GPM, 3 GPM, 5 GPM, 10 GPM, 15 GPM, 20 GPM, 30 GPM, 50 GPM, 100 GPM Our experienced sales and technical support personnel will help you select the correct system for your specific application depending on all of the unique conditions at your plant. In addition, because we use only the highest quality components in the overall design (Gardner Denver vacuum pumps, Siemens PLCs, Gems low flow switches, Watlow heaters, Viking gear pumps, and Baldor motors), our VDOPS is the most reliable, durable, and user-friendly system available in the industry today.
Varnish Removal Options
Varnish contamination in the turbine lube oil systems of gas turbines has recently become a major concern for maintenance personnel. For this reason, Oil Filtration Systems, LLC now offers a “varnish removal” option on all of our Vacuum Dehydration Oil Purification Systems (VDOPS). By diverting the flow of turbine oil through specially formulated granular adsorbent media, soluble varnish can be effectively removed from the oil, eventually resulting in the removal of varnish that has plated out on critical components, including servo valves in the speed control system.

Employs Most Efficient Filter Elements
High-efficiency filter elements for particulate removal from all mineral-based and synthetic hydraulic, lubrication, dielectric, and turbine oils. Our elements are constructed with the highest quality micro-fibrous glass filtration medias available. Our filtration technology, incorporates medias that are layered to achieve optimal performance characteristics. Our elements are suitable for use in the most demanding applications, and they are designed and tested to provide the highest level of efficiency with the maximum dirt holding capacity. All OFS filter elements have particulate removal efficiencies of Beta(c)>1000 (99.9% for the stated micron size), which is based on ISO 16889-1999 testing standards. They are available in a wide range of micron sizes to suit virtually any application (2.5, 5,7,12, and 22-Micron).
