This proprietary, large diameter,
disposable filter system features longfilter life and easy filter change outs.
Performance• Delivers excellent condensate
filtration combined with absolute ironoxide removal.
• Captures suspended copper, silica,and sulfate contaminants effectively.
• Captures suspended contaminants
inside the filter cylinder for clean andsimple filter element removal anddisposal via Pall’s unique filter
construction that uses an inside-out
flow design.

permits high flow rates within a given
filter envelope.
• Up to 50% smaller filter systems possible.
• Dramatic reduction in number of filter
elements to handle.
• All plastic, coreless construction
minimizes waste disposal.
• Standard vessels capable of flow rates
from 250 to 5000GPM.
Filter recommendations• Ultipleat High Flow filter cartridge
Applications• Condensate filtration during plant
start-up• Combined cycle condensate• Small coal fired plants

Performance
The Hydro-Guard Basic System is an
economical system for applications that
do not require the critical performanceoffered by the Hydro-Guard Demin
System. This is the basic workhorse ofcondensate particulate filtration and isideal for start-up use or full flow use ona tight budget.

PALL SYSTEM RETROFITS
Performance
Outdated components on older systems
could be hurting your facility’s
productivity. You can replace outdated
control panels, tube sheet assemblies,
filter sealing hardware, valves, pumps,
precoating systems and filter vessels
with quality Pall retrofits. Also, upgrade
obsolete string wound filters in existing
vessels with high performance elements
such as the HGCoLD R Melt Blown
backflushable filter.

Features and benefits• Effective backflushing saves filter
replacement costs• Absolute iron oxide retention• Effective deionization• Basic, reliable valves, controls,
and piping designs
Filter recommendations• Hydro-Guard CoLD R filter element
Applications• Predominantly used in drum boiler
and combined cycle power plants
for start-up, partial flow, or full flow
condensate polishing.

Features and benefits• Ensure fewer system breakdowns
and repairs with new valves, pumps
and filter sealing hardware.
• Achieve longer runs between
backflushes, better filtration
efficiency, and more productive useof powdered resin precoats with
Pall’s advanced filter technologies.
• Replace unreliable, irreparable
analog systems at reasonable
cost with state of the art digital
control systems.
Applications• All 15-year or older powdered resin
precoat systems• Any system using string wound filters• Any existing backflushable systemwith analog controls• Systems using springs to seal filter
cartridges
