Description
Save money with the Pall portable purifier
Water in hydraulic, lubrication, power transmission and insulating fluids adversely affects fluid performance and is a threat to system reliability.The Pall HNP022 purifier solves the problem and unlike centrifuges and coalescers, it removes both free and dissolved water and gases.
Features - Water, Gas and Particulate Removal
- The HNP fluid conditioning purifier removes:
- 100 % free water and as much as 90 % of dissolved water.
- 100 % of free and entrained gases and up to 80 % dissolved gases
- Fine particulate, using a high performance filter element
- Simple automated operation
- In-built water sensor
- Fully portable for multiple site application
Benefits - Reduced Maintenance Costs
- High performance water, gas and particulate removal leads to……
- Extension of fluid service life
- Minimized corrosion within systems
- Reduced fluid disposal
- Low operating costs
- Increased equipment reliability
How Does it Work
Vacuum dehydration is the most effective method of water removal at minimum cost and ease of use. Unlike other methods it removes both free and dissolved water and without significantly altering the properties of the oil.
Removing free water is never enough!
- 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 by the system heat exchanger. This prevents the formation of free water which is detrimental to fluid system components and the fluid.
- If only free water is removed at initial temperature, when oil is cooled the amount of free water in the oil can increase significantly.

Performance
HNP022 Performance
The HNP Oil purifier is designed to reduce and maintain the water content in a fluid system to below the saturation level of the system fluid ( < 300 ppm for a typical mineral oil). However, where a significant large water ingress occurs, the HNP022 can remove up to 12 gallons (45L) per day. The actual water removal rate depends on many variables, including system design, oil type, temperature, viscosity, water content, emulsion stability, and additives.Type
