PowerFlow XLP Series Oil Purifier / Oil Dehydrator
Oil Dehydration Systems for Cleaning and Dehydrating Lube and Hydraulic Fluids
Water contamination is one of the leading causes of hydraulic and lube oil failure. PowerFlow Fluid Systems’ oil dehydration and purification systems are engineered to remove free, emulsified, and dissolved water while simultaneously filtering particulate contamination. These machines are ideal for maintaining hydraulic systems, turbine lubrication systems, and large industrial gearboxes where moisture control is critical to equipment reliability and oil life.
XLP Series Oil Dehydration and Purification Systems remove contaminants such as solid particles, water, and gases from lube oils, hydraulic oils, and other mineral-based and synthetic fluids. XLP Series oil purifiers remove 100% of free and emulsified water and gases and at least 90% of dissolved water, gases, and light solvents. Particle filtration is certified to a beta ratio of βx (c) ≥ 1000 per ISO 16889 (Multi-pass filter rating). Choose filters rated at 3, 5, 10 or 25 microns.
Four Standard Sizes Available
Offline oil purifiers are made to recirculate on a reservoir. Connect to a reservoir with hoses or pipe and oil circulates through the machine and back to the reservoir. The optimum recirculation rate depends on many variables, but the chart below provides some general guidance.
| XLP Model | Circulation [GPM] | Approx. Reservoir Vol. [USGAL] |
| XLP5 | 5.5 | Up to 1000 |
| XLP10 | 11 | 1000 – 2000 |
| XLP20 | 22 | 2000 – 5000 |
| XLP50 | 50 | 5000+ |
Low Cost of Ownership
- The dry rotary lobe vacuum pump requires no cooling, seal water/oil, or pumping chamber lubrication.
- High-capacity filtration means fewer filter service indications.
- Minimal heat input means lower energy usage. The heater only engages when the oil is cooler than 120° F (adjustable).
Simple Operation
- Fully self-contained and self-diagnosing with PLC controls and large color touchscreen HMI.
- Convenient analog monitoring of oil pressure and temperature, vacuum level, and oil filter differential pressure.
- A water sensor continuously monitors water content and oil temperature.
- Scheduled maintenance simply involves changing the vacuum pump timing gear oil annually.
Superior Performance
- A packed column vacuum tower is designed to minimize the need for additive heat and vacuum.
- Engineered to create an ultra-thin, cascading film of oil, it greatly increases the oil surface area and supercharges the mass transfer rate.
- This gentle process eliminates the risk of oil degradation that can occur with other dehydration systems using high heat and deep vacuum.
Frequently Asked Questions About Oil Dehydration Systems
What machines are used to remove water from hydraulic oil?
The most effective machines for removing water from hydraulic oil are vacuum dehydration systems and oil purifiers with integrated dehydrators. These systems remove free, emulsified, and dissolved water while simultaneously filtering particulate contamination, helping extend oil life and protect hydraulic components.
What equipment removes water from turbine oil?
Turbine oil typically requires a vacuum dehydration oil purifier designed to handle large reservoir volumes and dissolved moisture. PowerFlow Fluid Systems oil dehydration units are engineered to efficiently dry turbine lubricants while maintaining ISO cleanliness targets.
How do oil dehydration systems work?
Oil dehydration systems typically use vacuum technology to lower the boiling point of water, allowing moisture to be removed at relatively low temperatures. As oil passes through the dehydrator, free, emulsified, and dissolved water is extracted while particulate filters remove solid contaminants.

Can emulsified water be removed from hydraulic fluid?
Yes. High-efficiency vacuum dehydration systems are capable of removing emulsified water from hydraulic oil. Unlike simple filtration, vacuum dehydration breaks the oil-water emulsion and extracts moisture down to very low ppm levels.
