PHFX Power Plant Iron Removal String Wound Filter Cartridge
| PHFX Power Plant Iron Removal String Wound Filter Cartridge |
The PHFX is a depth-filtration string wound cartridge engineered specifically for iron removal in power plant condensate systems. Available up to 70 inches in length, it supports high flow rates with minimal housing changes. Compatible with PP, cotton, and glass fibre media on SS304 or SS316L cores.

- SKU
- PHFX
- Built for Condensate Polishing: Designed around power-plant condensate duty and iron-oxide removal rather than adapted from general-purpose media.
- Inside-to-Outside Flow: Loads the dense inner bed first, using the full depth of the wound structure.
- Stainless Core: 304 or 316L center core carries the differential load at temperature.
- Long-Element Format: Lengths to 70" cut element count and housing footprint on high-volume systems.
- High Flow Capacity: 18–25 m³/h design flow per 40", up to 78 m³/h maximum.
- Wide Micron Range: 0.1–100 µm across the series, so one format covers polishing and bulk particulate duty.
- Defined Change-Out Point: Replacement at 2.5 bar differential gives maintenance a measurable trigger.

The PHFX uses a two-layer winding construction. The inner layer is made from high-temperature resistant material to prevent yarn shrinkage or falloff during thermal cycling, while the outer layer provides the primary filtration gradient. The surface can be coated with resin for combined filtration and desalination duty in condensate polishing units. The stainless steel centre core is rated to withstand the instantaneous impact pressure generated during resin backflush and burst cycles.
