Where filtration sits in a data center cooling system
| System | Typical published filtration | What FilterBridge supplies |
|---|---|---|
| Cooling tower / condenser water side-stream | About 3–10% of flow, up to 20% (DOE FEMP); cartridges about 5–50 µm (Fil-Trek) | Pleated jumbo and high-flow cartridges, standard cartridges, housings |
| Makeup water | Filter to 1 µm where possible (OCP Modular TCS) | 1 and 5 micron cartridges, RO pretreatment |
| Facility water system (FWS) into the CDU | Strainers about 100–500 µm; OCP lists primary filter ≤200 µm | Quote on request; strainers are not a stocked line |
| TCS / CDU secondary loop | 25 µm inline is common, ≤50 µm acceptable, with <5 µm side-stream (OCP; ASHRAE TC9.9) | Spec-driven quotes only. Send your filter spec |
| System flush / commissioning | Cartridges or bags about 5–50 µm (Fil-Trek) | Cartridges by the case; bags on request |

What we supply
- Pleated jumbo high-flow cartridges, including the Hydronix HSC-170, for side-stream systems that move a lot of water through few housings.
- High-flow cartridges such as HHFC40-5.
- Standard 10" and 20" cartridges in 2.5" and 4.5" diameters, 1 to 50 micron (nominal), for makeup water prefiltration, polishing and replacement programs.
- Housings for standard and Big Blue–style cartridges.
- RO membranes and pretreatment cartridges for makeup water and humidification systems.
- Polypropylene felt filter bags (1 to 200 micron) are available on request for coarse or flush stages; glycol compatibility is confirmed by the manufacturer for the poly bags only. Send your fluid spec for cartridges.
Hydronix HSC series pleated jumbo cartridges
Most data center cooling plants we quote use cartridges rather than bags, and the HSC-170 is the most requested size. It is 7 3/4" × 30 3/4" with 170 sq ft of media, rated 105 gpm recommended and 150 gpm max. Standard pleated polyester versions come in 0.35, 1, 5, 10, 20, 50, 100 and 150 micron (140°F max), and all-polypropylene versions are absolute rated at 0.2, 0.35, 0.45 and 1 micron (176°F max).
We quote case and bulk quantities within one business day and can cross-reference your current element. See the HSC-170 page or call (657) 500-0938.

Questions and answers
What cartridge do data center cooling plants use most?
For cooling tower and condenser water side-stream systems, large pleated high-flow cartridges are common. The Hydronix HSC-170 pleated jumbo cartridge (7 3/4 in by 30 3/4 in) is the most requested HSC size we quote. Your treatment program or engineer sets the micron rating.
Are your micron ratings absolute or nominal?
Each product page gives the rating as the manufacturer publishes it. For the HSC series, standard pleated polyester cartridges come in 0.35, 1, 5, 10, 20, 50, 100 and 150 micron, and all-polypropylene versions are absolute rated at 0.2, 0.35, 0.45 and 1 micron.
Can you supply commissioning volumes?
Yes. Cartridges are available by the case. Tell us quantity and timing in your quote request.
What do you need for a quote?
Part number or size (length and diameter), micron rating, media, flow rate, fluid and temperature, and quantity. See the filtration RFQ checklist.
