The dosing station is a tool suitable for the preparation, storage and dosing of the most varied chemical products in solution. Its design and the materials used allow a wide range of applications. Whether it is a standard use, or, due to a variable water flow, it is necessary to make the treatment proportional, IDRO Group has studied solutions for every need, also where it is not possible to use electricity, they are proposed simple and economic solutions using gravity dosers for sodium hypochlorite.
