nnnnHLP22 Oil Purifier
nnnnDescription
nnnnLeveraging more than 30 years of design and field experience,
nnnnPall presents the second in its family of HLP series fluid
nnnnconditioning purifiers - the HLP22 Oil Purifier.
nnnnThe HLP series combines the water removal performance
nnnnof mass transfer purifiers with high reliability and ease-of-use to
nnnnhelp ensure maximum equipment uptime and lowest cost of
nnnnownership - enabling you to focus on your process, and not
nnnnyour equipment.
nnnnImproved Performance
nnnnThe Pall HLP series purifier has a new vacuum tower design
nnnnthat results in very efficient water removal.
nnnnMaximum Reliability, Lower Cost of Ownership
nnnnHLP series purifiers are designed for maximum uptime, and
nnnnhave proven themselves In the field, exhibiting higher utilization
nnnnrates even in the most demanding and continuous duty
nnnnapplications.
nnnnThe HLP22 uses specially selected components to help ensure
nnnnmaximum reliability and lower cost of ownership. These premium
nnnncomponents Include:
nnnn• Best-ln-class Allen Bradley PLC
nnnn• Reliable Elmo Rietschle vacuum pump with 12 month service
nnnninterval.
nnnn• Viking gear pumps - proven performers for more than 20
nnnnyears in Pall purifier
nnnnControlling the dissolved as well as the free water In the reservoir Is critical in ensuring the absence of free water during operation.
nnnnWith the Pall HLP22 purifier, this is done efficiently, easily, and reliably The diagram below Illustrates the concept.
nnnnRemoving free water is never enough!

nnnn1 Initial water content is above saturation
nnnn(free water).
nnnn2 Maximum water removal capability of "free water
nnnnremoval" devices (coalescers, centrifuges, etc.)
nnnnis to the oil's saturation point.
nnnn3 Water content achieved with mass transfer
nnnndehydration is significantly below the oil's
nnnnsaturation point.
nnnn4 Water content achieved with mass transfer
nnnndehydration remains below the oil's saturation
nnnnpoint even after oil is cooled. This prevents the
nnnnformation of free water, harmful to the system.
nnnn5 If only free water is removed at initial temperature,
nnnnwhen oil is cooled the amount of harmful free
nnnnwater in the oil can increase significantly.
