Pure water,
reimagined
at the frequency of nature.
Ondea is an innovative electromagnetic-frequency device engineered to eliminate limescale, rust and bacteria from any hydraulic network — without chemicals, without downtime.
- Limescale
- Dissolved at the source, continuously
- Rust
- Oxidation prevented inside the pipework
- Bacteria
- Microbial loads kept under control

The hidden cost of every water network.
Limescale, corrosion and biological contamination silently degrade pipes, machinery and water quality — driving constant maintenance, chemical treatment and infrastructure replacement.
Bacteria
Pathogenic colonies thrive inside stagnant or warm pipework, threatening water safety.
Biofilm
Microbial layers coat the inner pipe surface, shielding contaminants and degrading water quality.
Limescale
Hard-water deposits constrict flow, kill efficiency in heating and cooling circuits, and force descaling cycles.
Rust
Oxidation corrodes metal pipework, leaches into water and triggers premature infrastructure replacement.
Plug & play electromagnetic induction.
Ondea emits a tuned frequency package through a ferrite ring clamped on the pipe. The electromagnetic field propagates through the entire hydraulic circuit, treating water at every point.

- 01
Install
A ferrite ring clamps directly onto the pipe — metal or plastic, no cutting, no welding.
- 02
Connect
The low-voltage controller wires to the ring. True plug & play deployment in minutes.
- 03
Emit
A precisely tuned frequency package generates a stable electromagnetic field.
- 04
Propagate
The field travels through the whole circuit, dissolving limescale and inhibiting bacteria and rust.
Pure water, the Swiss way.
Chemical-free purification, combined bactericidal action and full data sovereignty — engineered in Switzerland.
Chemical-free purification
We don't remove the essential minerals — we only remove the impurities. The water you drink stays naturally balanced, without adding a single chemical.
EM + UV: 100% bactericidal
Electromagnetic frequencies combined with UV deliver guaranteed bactericidal action against Legionella, Pseudomonas, Escherichia coli and other pathogens.
Swiss private datacenter
All Ondea telemetry is stored in Soleblanca's own private datacenter in Switzerland — your data, sovereign and secure by design.
Healthier pipes. Healthier people.
Ondea doesn't just treat water — it restores pipework from the inside and improves daily life for the people who drink, cook and shower with it.
Pipework restored from the inside
By continuously dissolving limescale and inhibiting rust, Ondea regenerates the inner surface of your pipes — pressure is recovered, flow stays consistent and major maintenance is pushed years into the future.
Healthier skin, lighter kidneys
Without limescale, the shower no longer leaves mineral deposits on your skin — fewer irritations, less risk of dermatitis. Cleaner water also means less work for your kidneys, every single day.
A single sealed unit, always on duty.
Ondea integrates the electronic board, hydraulic circuit, probes and ferrite emitter in a compact industrial-grade housing — designed to be deployed once and run continuously.

- Compact, sealed enclosure ready for residential, commercial and industrial environments
- Low-voltage operation, silent and maintenance-free
- Non-invasive installation on existing pipework
Constant monitoring. Historical data. Total control.
Every Ondea device is continuously monitored and controlled in real time. A complete history of water-quality readings is stored so trends can be compared, anomalies investigated and performance proven over time.
Real-time monitoring
Live water-quality telemetry from every installation, accessible from anywhere.
Remote control
Adjust parameters, run cycles and update devices remotely — without any site visit.
Historical data
Every reading is stored and timestamped. Compare days, weeks or months at a glance.
Smart alerts
Threshold breaches and anomalies trigger instant notifications to your team.
One technology, many environments.
From a single family home to a complex industrial facility, Ondea protects pipework wherever water flows.
Residential
Anti-limescale protection for homes and apartments.
Commercial
Hotels, offices and schools — sanitation and efficiency.
