Hospital Water Systems
Hospital central plants run chilled water, heating hot water and cooling towers around the clock. Fine iron and mineral scale add filter work and cleaning in systems that are hard to take offline.
HydroFlux helps downstream filters capture fine iron, and we assess its effect on cooling tower scale. On suitable existing pipe, the bracelet can go on while the system runs.

01 / The challenge
Plants that run every hour of the year
A hospital plant serves patient areas, surgery and labs, so maintenance windows are short and planned well ahead.
- Round-the-clock operation
- Heating, cooling and process loads run every hour of the year, so drain-downs and cleanings need careful scheduling.
- Fine iron in older steel pipe
- Older steel piping sheds fine iron oxide that can pass standard filters and collect in coils, heat exchangers and valves.
- Filter loading
- Iron-rich material loads strainers and filters and adds to the maintenance team's work.
- Cooling tower scale
- Mineral scale builds up in towers and condensers and needs repeated cleaning.
- A documented water program
- Hospitals run documented water management programs. Any new equipment has to fit that program and the team that runs it.
02 / The solution
What HydroFlux does in a hospital plant
HydroFlux is a magnetic bracelet that clamps around suitable existing pipe. It adds no chemicals and needs no power.
- Iron to the filters
- The magnetic field helps fine iron gather into larger particles that downstream filters can capture.
- Cooling tower scale
- We assess whether treatment changes deposit behavior and ease of removal in your tower.
- Installs on suitable pipe
- The bracelet can go on while the system runs. We review any pipe preparation or added equipment first.
- No power
- The bracelet uses permanent magnets and needs no electricity, controls or consumables.
- Measured against a baseline
- We agree on measures such as iron levels, filter loading and cleaning frequency before a trial starts.
03 / Water safety
Your water management program stays in charge
HydroFlux works on iron capture and cooling tower scale. It is not a disinfection system, and we make no claims about Legionella or other pathogens.
It does not replace your water management program, biocide treatment or water testing.
04 / Applications
Where HydroFlux fits in a hospital plant
Start with a system that has a known iron or scale problem and a place to measure the result.
- 01
Chilled water loops
Central plant loops with steel piping, signs of iron and an existing filter or side stream.
- 02
Heating hot water loops
Closed heating loops where iron collects in strainers, coils and heat exchangers.
- 03
Cooling towers
Condenser water systems where scale builds up and the tower needs repeated cleaning.
- 04
Side-stream filtration
Bypass filters where captured material, flow and pressure can be measured during a trial.
05 / Evidence
Evidence so far
These results come from an airport chilled water plant and a cooling tower pilot, not a hospital. A trial measures what changes in your plant.
- Lower sampled iron
- 87%
- LAX, June–December 2024; later readings were higher
- Captured mass
- +9.1%
- Selected aggregated LAX tests
- Cooling tower pilot
- 9 days
- Softer, more easily removed deposits on the treated tube
06 / Validation
What we measure on-site
Every trial has a measurement plan, agreed with your facilities team before anything is installed.
- 01Iron levels in water samples
- 02Captured material per volume filtered (g / 1,000 gal)
- 03Differential pressure across filtration
- 04Filter and strainer service frequency
- 05Deposit buildup and ease of removal (cooling towers)
- 06Cleaning and maintenance work orders
07 / Questions
Common questions
Does HydroFlux require a shutdown to install in a hospital?
Usually not. On suitable existing pipe, it clamps on with no drain-down or shutdown. Some sites need pipe preparation or added equipment first, which we plan with your facilities team.
Does HydroFlux control Legionella or other pathogens?
No. HydroFlux is not a disinfection system, and we make no claims about Legionella or other pathogens. It does not replace your water management program, disinfection or testing.
Does HydroFlux replace chemical water treatment in a hospital?
No. HydroFlux adds no chemicals and works alongside your approved water treatment and corrosion-control program. Your water treatment team controls any changes to that program.
Which hospital systems should be assessed first?
Start with a chilled water or heating hot water loop that shows iron and has a filter or side stream, or a cooling tower that needs repeated scale cleaning.
What power does HydroFlux need?
The magnetic bracelet needs no electricity. Pumps, powered filters and other equipment still need their normal utilities and maintenance.
Discuss your system
Start with one loop or tower that has a known iron or scale problem. We agree on what to measure before anything is installed.
