Data Center Facility Water
Fine iron oxide can pass standard filtration and collect across chilled-water loops, heat exchangers, and side-stream systems.
HydroFlux helps downstream filters capture fine iron. On suitable existing pipe, the bracelet can go on while the loop runs.
01 / The challenge
No window for a shutdown
Data center cooling has to keep running, which leaves little time to drain and clean a loop once fine iron builds up inside it.
- Continuous uptime
- Facility cooling cannot wait for pipe cutting, drain-down, or long installation windows. Any treatment must fit live operations.
- Fine iron escapes filtration
- Sub-5-micron iron oxide can pass standard filters and collect on coils, heat exchangers, valves, and low-flow areas.
- Filter loading and pressure
- Iron-rich material increases filter work and can contribute to differential-pressure changes and unplanned maintenance.
- Water and treatment costs
- Cooling tower water, blowdown, and treatment costs grow with facility scale. Measure at the site before changing operations.
- Hard-to-prove savings
- Energy and maintenance outcomes depend on each facility. A credible business case needs a baseline, defined measures, and clear attribution.
02 / The solution
What HydroFlux does in a data center loop
HydroFlux uses a patented Halbach magnetic array to aggregate fine iron oxide into sizes your existing filtration can capture. It adds no chemicals and requires no power.
- Iron to the filters
- The magnetic array promotes aggregation so existing side-stream filtration can capture more iron-rich material.
- Your treatment program stays
- HydroFlux adds no chemicals and operates beside the approved water treatment and corrosion-control program.
- Installs on a live loop
- The bracelet can attach to suitable existing pipe while the loop runs. We review any pipe preparation or added equipment first.
- No power
- Permanent magnets require no electricity, controls, consumables, or connection to facility monitoring systems.
- Measured against a baseline
- Track iron concentration, captured filter mass, differential pressure, and maintenance events against an agreed baseline.
- One loop first
- Assess a facility water loop with a known iron problem before expanding to other systems or sites.
03 / For data center operators
Where to start
Fine iron creates a measurable maintenance problem when it loads filters, collects in low-flow areas, or reaches heat-transfer equipment.
Start with one facility loop. Measure iron concentration, filter capture, pressure, and maintenance before deciding whether to expand.
04 / Applications
Where HydroFlux fits in your facility
Focus the first assessment on facility water systems with known iron and an existing capture point.
- 01
Central plant chilled water
Facility loops with steel piping, known iron loading, and existing bag, cartridge, or sand filtration.
- 02
Side-stream filtration
Bypass loops where captured mass, flow, and differential pressure can support a measured iron pilot.
- 03
Cooling tower loops
Facility water systems where operators can measure iron, deposit behavior, blowdown, and approved chemistry changes.
- 04
Utility hot water loops
Building and support-system loops with visible iron accumulation and a defined downstream capture point.

06 / Validation
What we measure on-site
Every deployment includes a measurement plan. The results come from your own facility's data.
- 01Filter mass captured per volume filtered (g / 1,000 gal)
- 02Differential pressure trend across filtration
- 03Iron concentration trend (lab sampling when available)
- 04Maintenance events related to fouling (work orders / cleanings)
- 05Cycles of concentration and blowdown impact (cooling towers)
- 06Customer-selected thermal or energy measures when attribution is practical
07 / Questions
Common questions
Does HydroFlux require a system shutdown to install in a data center?
Usually not. On suitable existing pipe, it clamps on with no drain-down or downtime, so the data center keeps running. Some sites need pipe preparation first.
What data center systems should be assessed first?
Start with facility chilled-water or side-stream filtration loops that show measurable iron loading. Direct-to-chip and immersion systems require separate technical review.
Can HydroFlux treat both chilled water loops and cooling towers in a data center?
HydroFlux is evaluated for facility chilled-water loops, side-stream filtration, cooling towers, and utility water systems. Each application requires site review.
Does HydroFlux replace chemical water treatment in data centers?
No. HydroFlux adds no chemicals and works alongside the approved water treatment and corrosion-control program.
What power does HydroFlux require in a data center?
The magnetic bracelet needs no electricity. Pumps, powered filters and other equipment still need their normal utilities and maintenance.
