Pall HNP Vacuum Dehydrators

Pall HNP074 Series Oil Purifier

The Pall HNP074 oil purifier is designed to remove water from fluids therefore maintaining lubricity properties, minimising fluid oxidation and reducing aeration.

Water in hydraulic, lubrication, power transmission and insulating fluids adversely effects fluid performance and in addition is a threat to system reliability. This often invisible contamination promotes oil oxidation, the formation of acids, bacterial growth, and can also lead to a reduction in lube film thickness. In time, this results in corrosion, increased wear and expensive system failure. When free water contamination interacts with system fluids the consequences are increased operating costs from reduced oil life and increased fluid replacement and disposal costs.

Benefits of the Pall HNP074 Series Oil Purifier

  • High performance water, gas and particulate removal – most of all
  • Extension of fluid life as a result of Purifier
  • Minimised corrosion within systems – especially relevant
  • Therefore reduced fluid disposal
  • As well as reduced operating costs
  • Also Increased equipment reliability
  • In addition simple automated operation
The Pall HNP fluid conditioning purifier uses vacuum dehydration to remove 100 % free water and as much as 80 % 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 coupled with 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) >1000) Ultipleat® SRT filter elements. In addition, a WS10 Series water sensor measures water content and temperature at purifier inlet, allowing the purifier to operate only when the water content rises above a pre-determined level.

Removing Free Water is in fact 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 us significantly below the oil’s saturation point.
  • Water content achieved with mass transfer dehydration remains below the oil’s saturation point even after the oil is consequently cooled by the system heat exchanger. This also 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.
