Canadian red cedar wood is visually pleasing and has a smooth texture. Beyond aesthetic, this noble material invites you to commune with the surrounding environment. Whether indoors with background music and subdued lights or outdoors with fresh air and the whispers of nature offering a breathtaking view of a blue or starry sky. During these moments of relaxation, silence is gold.

The Silent+ mode is an extra feature of our hot tub over other hot tubs and spas whose jet machines are just as noisy for the user as for other customers. Thanks to its quiet power and patented injection system, our treatment process consequently ensures that the water is perfectly healthy and clear at all times in spite of heavy use.

Hot tubs, spas, and jacuzzis are a premium asset for any kind of accommodation willing to offer first-class comfort to their customers.

While a hot tub is ideal for high-end accommodations, it also requires precise and rigorous maintenance.

However, many companies offer a poorly adapted water treatment system like a swimming pool one. In fact, some even go so far they exempt themselves from any type of water treatment !

For 10 years, we have been implementing a water treatment unit with an eco-responsible approach.
This approach is carried out in close collaboration with our partners who offer a variety of unusual accommodations.
Innovative in several ways, this filtration system meets the needs of professionals who are subject to very strict hygiene standards.

Years of experience

An eco-responsible approach

Product benefits for both operators and customers.

Our water filtration system is the perfect answer to the ecological aspirations of today.
Indeed, no expensive and harmful chemicals are needed to keep the water pure.

Thanks to a customized UV-C filtration with a patented ozone injection system, the water is subject to a complete sterilization of the highest quality, without any addition of chlorine* or any other product.

*where required by the regulations of certain countries, the minimum chlorine injection is automatically adjusted to the minimum rate of the standard in place.

Hot tub and jacuzzi, open to the public, water treatment, spas
The eco-responsible approach allows our hot tubs, spas, and jacuzzis to be both pleasant and perfectly hygienic while respecting the environment, even beyond what current regulations require.

Our unique filtration and water treatment system sets us apart from our competitors for businesses and establishments open to the public. To sum up, the advantages are both economical and practical.

Equipping your establishment with one or more of our hot tubs attracts customers who want to completely relax. They will experience a feeling of floating in weightlessness, thanks to a water level reaching one meter on average, in contrast with Jacuzzis which are more shallow.
