Hydro-Guard® CoLD R Series Filter Cartridges

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.
