NEW: HNP075 Series Oil Purifier
For fluid viscosities to 700 cSt
Water in hydraulic, lubrication, power
transmission and insulating fluids adversely
affects fluid performance and is a threat
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, leading to reduced lubricity and load carrying
ability, oil oxidation and the resultant formation of acids,
and additive precipitation. The consequences are reduced
fluid service life, increased fluid procurement and
disposal costs.
The ‘Pall’ HNP075 Series Oil purifier is designed for use
with medium to large oil systems, particularly where high
viscosity fluids are employed.
The Pall HNP 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.
HNP075 Series (mobile) Oil Purifier
Vacuum dehydration is the most effective method of water
removal at minimum cost and ease of use. Unlike other Select the HNP075 oil purifier for:
methods it removes both free and dissolved water and • High performance water, gas and particulate removal
cannot burn or otherwise significantly alter the properties
• Extension of fluid service life
of the oil.
• Minimized corrosion within systems
Particulate contaminant removal is achieved using high
performance rated Ultipleat® SRT filter elements. • Reduced fluid disposal
In addition, a water sensor measures water content and • Reduced operating costs
temperature at the purifier inlet, allowing the • Increased equipment reliability
purifier to operate only when the water content rises • Simple automated operation
above a pre-determined level. • Remote monitoring option
Removing free water is never enough!
