The BWT bestsave S is a scale protection pad for hot beverage makers with integrated water tanks, such as coffee machines, coffee fully automatic machines, and compact vending machines. After unpacking, it is briefly rinsed under running water and placed on the tank bottom; no installation is necessary. A food-grade ion exchanger binds calcium ions, thus preventing the formation of calcium carbonate, the integrated activated carbon improves odor and taste and reduces heavy metals such as copper and zinc. After filling, the exchanger needs 8 to 10 hours, therefore BWT recommends treatment overnight. Size S measures 95 x 65 x 17 mm, the capacity is 50 litres at 10 degrees carbonate hardness.
Capacity: 50 litres at 10° carbonate hardness
Packaging unit: 20 pcs. This item is only available in bulk packaging.
