Your questions, answered
  • You can use our water treatment systems with any coffee machine as all our fittings are standardized. 

    Many of our café clients use our water filters for commercial coffee machines from brands like these: 

    • La Marzocco 
    • Sanremo 
    • Ascaso 
    • Astoria 
    • Faema 
    • Rancilio 
    • La Cimbali 
    • Rocket Espresso 
    • WMF
  • Yes, you can achieve SCA-compliant water with our products 

    Our direct flow reverse osmosis filter RObust COFFEE was specifically designed for coffee making and delivers SCA-compliant water through four steps: 

    Step 1: Pre-filtration 

    Mechanical impurities, chlorine, chlorinated compounds and natural organic substances are removed from your inlet water. 

    Step 2: Membrane filtration (RO step) 

    The water is pushed through a semi-permeable reverse osmosis membrane to remove 99.8% of dissolved impurities, including viruses and bacteria. 

    Step 3: Special coffee cartridge 

    Now the water is enriched with calcium (Ca) and magnesium (Mg) to enhance the aromas of the coffee brewed by your baristas. 

    Step 4: Post-carbon filtration 

    In this final step, the water is purified one last time to remove any residual odours that might impair the taste and aroma of your coffee. 

    But even if you decide against the RObust COFFEE for whatever reason, you can combine one of our reverse osmosis filters in your café with sediment filters, water softeners and mineralisation cartridges as needed to achieve the water quality recommended by the SCA. 

    If you’re unsure how to do that, we’d love to help you plan the ideal water filtration system for your coffee shop. 

    Plan your water treatment system now 

  • Yes, that is possible. 

    The universal construction of our water treatment systems allows for a very easy installation as well as combination with other brands. 

    Many café operators who don’t use our 4-in1 solution RObust COFFEE, for example, combine one of our reverse osmosis filters like the RObust Mini or the RObust 1500 with the BWT Bestmin or another mineralisation cartridge. 

  • Yes, you can achieve the TDS levels recommended by the SCA with Ecosoft water treatment systems. 

    The SCA recommends a TDS level of 75–250 ppm, although it’s important to note that the composition of the Total Dissolved Solids has a significant impact on the taste of your coffee. 

    With its combination of calcium (Ca) and magnesium (Mg), the RObust COFFEE creates water that’s optimized to enhance the unique aromas of coffee. 

  • While it’s not strictly necessary to use a tank when using our commercial water filtration system in your café, we do recommend it: Using a tank helps to average TDS levels in the water, which results in consistent coffee flavour.
