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.

Performance Specifications
Maximum operating temperature
65 °C (150 °F)
Maximum differential pressure
2.07 bard (30 psid) @ 65 °C (150 °F)
Typical Flow vs. Differential Pressure for Application Sizing1
Unit conversion: 1 bar = 14.5 psi
1 Flow rate is for a 152 cm/60 inch 30 μm cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
