About JAEGER SAS
A French company based near Chartres, JAEGER SAS designs and manufactures LIMPEO — an innovative, eco-friendly electromagnetic anti-scale solution, made in France.
Our story
JAEGER SAS was born from a simple observation: limescale costs French households and businesses dearly. Scaled-up pipes, prematurely failing appliances, wasted energy, polluting chemical descalers. Traditional solutions such as salt-based softeners demand regular maintenance, expensive consumables and alter water quality.
To address these challenges, JAEGER SAS developed LIMPEO: an electromagnetic anti-scale device that uses no chemicals, no salt and requires no maintenance. Designed and manufactured in France at our Eure-et-Loir facility near Chartres, LIMPEO represents years of research and development in physical water treatment. Our ambition: to offer a lasting, economical and environmentally responsible alternative to chemical water treatment.
Headquarters
JAEGER SAS is located in Eure-et-Loir, near Chartres, in the Centre-Val de Loire region of France. This strategic location gives us direct access to some of the hardest-water areas in the country while ensuring efficient logistics across the entire French territory.
Our purpose
To make effective, eco-friendly and durable water treatment accessible to everyone. LIMPEO embodies this vision: a technology that protects installations without polluting, without consumables and without maintenance for 25 years.
Our mission
At JAEGER SAS we believe water treatment should never force a compromise between effectiveness and environmental responsibility. Our mission is to deliver anti-scale solutions that eliminate the constraints of traditional chemical treatments. LIMPEO transforms calcium crystallisation through a purely physical process, preserving natural water quality while durably protecting pipes and equipment. We are committed to healthy water, protected installations and zero environmental impact.
