In all countries, the distribution of drinking water is accompanied by a complex regulatory regime, in which the protection of the environment takes an increasingly prominent place. The strength of Herli is to offer truly effective products that also guarantee compliance with all regulatory requirements.

European regulations (biocide directive, REACh) now provide a common reference framework for all countries and products. It takes into account, in total transparency, all the impacts on health and the environment. Herli products naturally meet these requirements.

Herli products and processes are designed to be effective in sensitive environments and are subject to a strict regulatory framework.

Herli affirms its commitment “to the service of water and the environment” since 1992. Beyond words and modes, this commitment is concretized by products whose impact on the environment is controlled and negligible with regard to Of the health benefits they provide, and offer a tangible alternative to the excessive use of chlorine. This commitment is also reflected in an unstoppable effort to inform and train good practices and good actions for men and women in the field.

Herli’s commitment to the environment has been recognized by ISO 14001 certification since 1996.
At the service of the environment, Herli uses the most natural and most effective disinfectant: hydrogen peroxide (H2O2 or hydrogen peroxide). This powerful oxidant destroys the micro-organisms, then decomposes into water and oxygen without generating any by-products. Hydrogen peroxide is always associated with a catalyst that reinforces its action and with stabilizing agents that guarantee its effectiveness over time. These preparations are simple and safe to use every day for bacteria, viruses, algae and molds.
Who is afraid of chemistry? Not Herli customers, who trust a responsible company, certified ISO 9001 (quality) and ISO 14001 (environment). In accordance with the regulations, implemented with discernment, Herli products contribute to the improvement of the environment: elimination of pathogens and their feeder supports, protection of installations, reduction of the use of chlorine: a positive balance for all!
