HNP023 Series Oil Purifier

Water in hydraulic, lubrication, power transmission and insulating fluids adversely affects fluid performance and is a threatens to system reliability.

Water contamination promotes corrosion and fluid system component wear, resulting in reduced component life and increased maintenance costs. It also degrades fluid properties, reducing lubricity and load-carrying ability, oil oxidation and the resultant formation of acids, and additive precipitation. The consequences are reduced fluid service life and increased fluid procurement and disposal costs.

The Pall HNP023 Series Oil purifier is designed for small to medium oil systems, particularly where high viscosity fluids are employed. They can effectively remove 26 liters of water per day from the oil*.

The Pall HNP hydraulic fluid conditioning purifier uses vacuum dehydration to remove 100 % free water and as much as 90 % of dissolved water. It will also remove 100 % of free and entrained gases and up to 80 % dissolved gases.

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 cannot burn or otherwise significantly alter the properties of the oil.

Particulate contaminant removal is achieved using high performance rated (ß3(c) >2000) Athalon® filter elements.

In addition, a WS12 Series water sensor measures water content and temperature at fluid conditioning the purifier inlet, allowing the purifier to operate only when the water content rises above a pre-determined level.

* Water removal rates are affected by the fluid viscosity, temperature, form of water (free or dissolved), and the amount of water present. Pall utilizes a well-defined and repeatable test procedure that ensures thorough water dispersion in the test fluid initially and throughout the test. The water removal rate shown is for tests with ISO VG 32 mineral-based turbine lube oil at 60 °C in the range of 2.6% to 1.4% water. The removal rates at higher water concentrations will be significantly higher.

Select the HNP023 oil purifier for:

  • High-performance water, gas, and particulate removal
  • Extension of fluid service life
  • Minimized corrosion within systems
  • Reduced fluid disposal
  • Reduced operating costs
  • Increased equipment reliability
  • Simple automated operation
  • Remote monitoring option

Removing free water is never enough!

1. Initial water content is above saturation (free water).
2. Maximum water removal capability of ‘free water removal’ devices (coalescers, centrifuges, etc.) is to the oil’s saturation point.
3. Water content achieved with vacuum dehydration is significantly below the oil’s saturation point.
4. Water content achieved with vacuum dehydration remains below the oil’s saturation point even after oil is cooled by the system heat-exchanger cools the oil. This prevents the formation of free water, which is detrimental to fluid system components and the fluid.
5. If only free water is removed at the 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.
