HLP22 Oil Purifier

nnnn

Description

nnnn

Leveraging more than 30 years of design and field experience,

nnnn

Pall presents the second in its family of HLP series fluid

nnnn

conditioning purifiers - the HLP22 Oil Purifier.

nnnn

The HLP series combines the water removal performance

nnnn

of mass transfer purifiers with high reliability and ease-of-use to

nnnn

help ensure maximum equipment uptime and lowest cost of

nnnn

ownership - enabling you to focus on your process, and not

nnnn

your equipment.

nnnn

Improved Performance

nnnn

The Pall HLP series purifier has a new vacuum tower design

nnnn

that results in very efficient water removal.

nnnn

Maximum Reliability, Lower Cost of Ownership

nnnn

HLP series purifiers are designed for maximum uptime, and

nnnn

have proven themselves In the field, exhibiting higher utilization

nnnn

rates even in the most demanding and continuous duty

nnnn

applications.

nnnn

The HLP22 uses specially selected components to help ensure

nnnn

maximum reliability and lower cost of ownership. These premium

nnnn

components Include:

nnnn

• Best-ln-class Allen Bradley PLC

nnnn

• Reliable Elmo Rietschle vacuum pump with 12 month service

nnnn

interval.

nnnn

• Viking gear pumps - proven performers for more than 20

nnnn

years in Pall purifier

Controlling the dissolved as well as the free water In the reservoir Is critical in ensuring the absence of free water during operation.

nnnn

With the Pall HLP22 purifier, this is done efficiently, easily, and reliably The diagram below Illustrates the concept.

Removing free water is never enough!

Temperature

nnnn

1 Initial water content is above saturation

(free water).

nnnn

2 Maximum water removal capability of "free water

nnnn

removal" devices (coalescers, centrifuges, etc.)

nnnn

is to the oil's saturation point.

nnnn

3 Water content achieved with mass transfer

nnnn

dehydration is significantly below the oil's

nnnn

saturation point.

nnnn

4 Water content achieved with mass transfer

nnnn

dehydration remains below the oil's saturation

nnnn

point even after oil is cooled. This prevents the

nnnn

formation of free water, harmful to the system.

nnnn

5 If only free water is removed at initial temperature,

nnnn

when oil is cooled the amount of harmful free

nnnn

water in the oil can increase significantly.
