Water with the protection factor for catering and vending. With BWT bestprotect, you can optimise raw water for catering applications in a targeted way. This filter system ensures balanced mineralisation and a consistently high pH value in the filtrate – key factors that minimise the risk of corrosion. Hardness-forming calcium ions are practically entirely removed and deposits of limescale and gypsum prevented in the case of raw water containing carbonates or sulphates. Insoluble or difficult-to-remove deposits in machines are now a thing of the past.
