Portable Fluid Purification
Problems associated with fluid contamination can vary. Free and dissolved water
can break down oil through reduced lubricity, oxidation and acid formation. Oil
that is free of water has a reduced tendency to oxidize and form organic acid, even
when exposed to high temperature. The presence of organic acid compounds leads to
corrosion. Trapped air can damage both fluid and system components and cause poor
system response due to variations in system pressure. Air can cause erosion and
pump cavitation, accelerate hydraulic and lube oil oxidation and cause loss of insulation
properties in dielectric fluids. Solids in your fluid system can cause premature
wear of a variety of components. Wear causes numerous problems in hydraulic systems.
Erosion and failure of nozzles, flappers, slide valves, etc. result from wear.
The Pall HVP Portable Fluid Purifier removes water, air and solid contaminants from
hydraulic fluids. The immediate and long term benefits are reduced system wear that
allows you less frequent component changes and a smaller spare parts inventory can
be maintained. Another benefit is improved system performance, which translates
into fewer costly operation delays and increased system reliability. You will also
see improved on-line performance, extended fluid life due to sharply reduced contamination.
The HVP Fluid Purifier will also reduce fluid disposal costs and environmental risk
by extending your fluid life and minimizing waste costs. The Pall Portable Fluid
Purifier extends fluid life, reduces disposal costs, minimizes waste and increases
equipment uptime. Some of the key markets that use Pall Purifiers are Power Generation
for main turbine lube oil, boiler feed pump turbine, transformer oil, coal pulverizer/conveyors
and bulk oil storage.

Decontaminating Fluid Syststemsn
Unwanted water, particulate and gaseous contamination in fluid systems can severely
impact process efficiency and product quality. Utilizing the principles of mass
transfer and vacuum dehydration, the Pall HVP series portable oil purifiers effectively
and efficiently remove 100% of the free water and 80% to 90% (or more) of the dissolved
water from the fluid system. They will also remove 100% of the free and entrained
gases and up to 75% of the dissolved gases.
Highly efficient particulate removal can be achieved by using a single, Pall Ultipor
III style element rated at Beta X(c) = 1,000, in accordance with ISO 16889. Cleanliness
levels of ISO 16/14/12 (per ISO 4406:1999) or better are typical. The HVP employs
a programmable logic controller (PLC), which monitors and sequences its operation.
The PLC will automatically shut down the purifier in the event certain operating
limits are exceeded and initiate the purifier diagnostic alarm and help screen.
This will display all alarm conditions, probable cause of the alarm(s) and help
screens that delineate corrective measures to rectify them. An in-line temperature/water
sensor is mounted at the inlet of the purifier, which continuously monitors fluid
temperature and water content. It provides both local and remote monitoring capabilities
and can be programmed with various alarm points for temperature and water content.
These units are very portable and easy to install. They only require an inlet and
outlet connection to the fluid system and the appropriate power source – 480v/3Ph/60Hz.
There are no water or compressed-air line connections required. They will reduce
system wear; improve on-line and system performance; extend fluid life; and reduce
fluid disposal costs and environmental risks.
