Description
The culmination of 30 years of expertise in water control for lubrication and hydraulic control circuits
With a design based on 30 years of actual field experience, the Pall HLP6 oil purifier combines the excellent efficiency of mass transfer purifiers with an exceptional level of reliability and ease of use. Water contamination in oil systems is responsible for major maintenance and operational problems of critical components in lubrication and hydraulic circuits. From power generation turbines to paper machines, these problems include:
- Increased corrosion in the system, especially at bearing locations
- Increased oil oxidation and acid build-up
- Sluggish response of control systems
Free water and dissolved water
In a typical oil system, temperature swings constantly change the dissolved water content of the oil. At the reservoir location it is critical to remove not only free water, but also a large portion of dissolved water. This is the only way to ensure that free water will not appear when the fluid goes through the cool parts of the system, especially when an oil cooler is used downstream of the reservoir.

Performance
The Pall HLP6 purifier has a newly redesigned vacuum tower which allows for very efficient water removal. It is designed to remove 100% of free gases and water (under steady state conditions), and up to 80% of dissolved gases and water. It is also designed to remove solid contaminants, with efficiency of 99.9% (down to 3 microns).
The HLP6 oil purifier showed a 40% faster dehydration rate when compared to a leading, similarly sized purifier.
The HLP6 oil purifier showed a 40% faster dehydration rate when compared to a leading, similarly sized purifier.
- Initial water content is above saturation (free water).
- Maximum water removal capability of "free water removal" devices (coalescers, centrifuges, etc.) is to the oil’s saturation point.
- Water content achieved with mass transfer dehydration is significantly below the oil’s saturation point.
- Water content achieved with mass transfer dehydration remains below the oil’s saturation point even after oil is cooled. This prevents the formation of harmful free water.
- If only free water is removed at initial temperature, when oil is cooled the amount of harmful free water in the oil can increase significantly
