Critical challenges

What’s endangering your hospital’s water systems?

Hospitals are complex facilities running huge energy and water systems with the highest operational and safety sensitivity.

01

Critical health risk — Legionella

Cooling towers and hot-water systems are hotspots for biofilm accumulation, which hosts Legionella bacteria. The Ministry of Health runs strict testing, and exceeding limits can force system shutdowns.

✓ With HydroFLOWUp to 99% bacteria reduction including Legionella, per SGS and ALS validation.
02

Energy loss in chillers and cooling towers

Israel’s hard water causes rapid limescale settling on heat exchangers — severely impairing heat transfer and requiring frequent make-up water.

✓ With HydroFLOWKeeping heat-exchanger surfaces clean — saving energy and water.
03

Chemical damage to pipework and equipment

Heavy use of biocides, chlorine and acids wears down pipework, causes accelerated corrosion and shortens the life of costly medical equipment.

✓ With HydroFLOWA chemical-free physical solution — protecting pipework and equipment.

The solution

How does HydroFLOW upgrade the medical centre?

An advanced electronic system providing full 24/7 protection for water systems, air conditioning (chillers) and cooling towers in hospitals. The system reduces limescale build-up, breaks down biofilm and dramatically reduces the need for toxic chemicals.

Independent lab validation
SGS and ALS

Independent lab tests document a significant reduction in bacteria, including Legionella, following disruption of the biofilm layer. The exact result varies by site.

24/7
Continuous protection

A continuous signal even when water is still — not only during flow.

None
Added chemicals

A physical solution with no additives to the water.

None
Ward shutdowns

Quiet external installation, with no pipe cutting.

Installation process

Three steps to an advanced solution.

01

System assessment

Our technical team carries out a full assessment of the hospital’s water and HVAC systems.

02

Installation

Quiet, external installation, with no pipe cutting and no disruption to ward operations.

03

Ongoing protection

A continuous signal operating 24 hours a day protects all systems, with the option to connect to the HydroKNCT monitoring system.

Case study from Israel

Mazor Mental Health Center

Case study — Israel

Heat-exchanger cleaning interval extended from 3–4 months to 17+ months

A medical centre in Israel extended the interval between acid cleanings of its heat exchanger from 3–4 months before installation to 17 months and counting afterward — using HydroFLOW units together with the HydroKNCT monitoring system.

The scientific mechanism

Limescale and biofilm feed each other — and that’s the real problem

In hospitals, limescale and biofilm aren’t two separate problems — they reinforce each other, together creating exactly the environment Legionella thrives in.

Step 1

Limescale creates a foothold

A rough, porous limescale layer provides biofilm with exactly the kind of surface it needs to establish itself.

Step 2

Biofilm protects the bacteria

The layer that forms provides bacteria — including Legionella — with both food and shelter from chlorine and thermal disinfection.

Step 3

Disinfection stops working

Even a properly run disinfection regime struggles to penetrate the double layer — the result: bacteria survive despite chemical treatment.

The practical implication: when limescale and biofilm are treated physically, the existing disinfection regime (chlorine, heat or biocide) goes back to working on the bacteria themselves — not on the layer hiding them. HydroFLOW doesn’t replace the water-safety plan — it helps it work as designed.
Application map

Across the entire hospital campus

Legionella control

Supporting the risk-management plan across the entire distribution system — long lines, dead legs and outlets.

Hot water and boilers

Protecting boilers, calorifiers and the hot-water system — exactly where Legionella tends to establish itself.

Cooling towers and chillers

Controlling limescale and biofilm on towers and condensers — protecting both hygiene and cooling efficiency.

Biofilm and biofouling

Disrupting biofilm along pipework, calorifiers and tanks — the source of most of the bacterial risk.

Limescale and deposits

Controlling calcium limescale on calorifiers, heat exchangers and outlets — less shelter for bacteria, less wasted energy.

Closed cooling circuits

Keeping chilled- and condenser-water circuits clean — including plate and shell-and-tube heat exchangers.

An important clarification upfront: HydroFLOW is not a disinfectant and does not replace the hospital’s water-safety plan — including temperature monitoring, water sampling, flushing procedures and the responsibility of the authorised person, per Ministry of Health requirements. The system operates within this framework as a physical protection layer that reduces limescale and biofilm — so the rest of the plan works far more effectively.
