Continuous Length, Backflushable, Precoat, Condensate Filter

Hydro-Guard CoLD R filter elements are manufactured using the CoLD Melt™ fiber production process. The CoLD Melt process permits the creation of multiple filtration zones within a single filter cartridge. The reverse graded pore density, multi-zone design provides customers with even precoating, efficient backflushing, and long filter life. Many power plants around the world have switched from string wound technology to Hydro-Guard CoLD R products for improved condensate polishing.

Product Feature	Product Benefit	Customer Benefit
Continuous Length Element	Uniform resin precoat	Improved deionization performance Optimized resin capacity utilization
Co-Located Large Diameter Melt Fibers	Resists collapse or compression under increasing differential pressure Rigid pore structure results in more consistent, reliable and reproducible filtration compared to string wound configurations	Reduced possibility of resin bleedthrough Stable filtration performance over the life of the element
Reverse Graded Pore Density Structure	Enhanced surface filtration High-efficiency backflushing	Longer element service life reduces number of filter change-outs and filter disposal costs Minimizes worker exposure in radioactive applications
All Polypropylene Construction	Reduced extractables - free of adhesives, binders and surfactants No rinse-up required Incinerable	No filtration related chemistry excursions Reduced start-up costs Reduced filter disposal costs
