Is electromagnetic treatment scientifically proven?

Yes. Numerous studies published in peer-reviewed journals (Coey & Cass, Kobe et al., Alimi et al.) confirm that magnetic fields modify calcium carbonate crystallization, promoting non-scaling aragonite over calcite.

Does LIMPEO alter drinking water quality?

No. LIMPEO does not change the pH, conductivity, or mineral content of water. Calcium remains present in a non-scaling form. The water remains perfectly safe to drink.

How long does installation take?

Installation is non-invasive: the device wraps around the existing pipe, with no water shutoff or plumbing modification. It typically takes less than 30 minutes.

What maintenance is required?

None. The LIMPEO device operates autonomously, with no consumables, no salt, and no filters to replace. Its lifespan exceeds 20 years.

What pipe types does LIMPEO work with?

LIMPEO is compatible with all pipe types: iron, copper, stainless steel, PVC, PER, composite, and multilayer. The range covers diameters from 25 mm to 100 mm.

How is it different from a traditional water softener?

Unlike a softener, LIMPEO requires no salt, no resin, and no maintenance. It discharges no brine into the environment and preserves the beneficial calcium in water. Zero extra water consumption.

Does LIMPEO work with very hard water (> 35°f)?

Yes. LIMPEO is effective on all water hardness levels. The harder the water, the more visible the benefit as the amount of limescale transformed into aragonite is proportionally greater.

Can LIMPEO be used on a closed heating circuit?

Yes. The "P" versions (like the J-1100-P) are specifically designed for looped circuits: central heating, hot water loops, industrial cooling circuits.

What is the device's power consumption?

Consumption is under 5 watts, less than €10 per year. This is negligible compared to the energy savings generated by eliminating scale from your installations.

Does LIMPEO remove already encrusted limescale?

Yes, progressively. LIMPEO's curative action combines calcium carbonate with dissolved CO2 to form soluble bicarbonate. Existing deposits dissolve over a period of 2 to 6 months.

Is the device warranted?

Yes. LIMPEO comes with a 2-year parts and labor warranty. The device lifespan exceeds 20 years with zero maintenance or consumables.

Can LIMPEO be self-installed?

Yes. Installation is simple: the device wraps around the existing pipe. No plumbing skills are required. An installation guide is provided. For professional installations, however, we recommend technician intervention.

How it works

A simple, scientifically proven physical process.

Electromagnetic field

The LIMPEO device generates a calibrated electromagnetic field around your pipe.

Crystal transformation

Limescale (calcite) transforms into aragonite, a non-scaling crystal form.

Continuous protection

Aragonite crystals remain suspended and are naturally flushed away with the water flow.

Validated by science

Independent university studies confirm the effectiveness of LIMPEO electromagnetic treatment.
