Learn moreThe BRITA PURITY C Quell ST C500 is intended for higher-throughput professional equipment. Compared with the C300, it provides substantially more capacity and increases nominal flow from 60 to 100 L/h. This makes it suitable for busy coffee, vending and catering installations where daily consumption and peak demand are higher.
At 10°dH carbonate hardness, the C500 is rated for 5,889 litres with a 30% fixed-bypass head. With a 0-70% variable head, capacity is 6,800 litres at 40% bypass for coffee, espresso or vending, or 4,675 litres at 10% bypass for combi and conventional ovens. Actual capacity depends on local water quality, bypass setting, equipment and usage.
The complete filter system measures 144 x 144 x 557 mm and weighs 6.9 kg when wet. Check the available height and ensure that the installation can support the wet system weight.
The four-stage process combines pre-filtration, carbonate-hardness reduction, activated carbon and final fine filtration. It reduces limescale formation, retains metal ions such as lead or copper, and reduces chlorine residues and other substances that can affect the finished drink or food. All water, including bypass water, passes through the activated-carbon stage.
What is included: one BRITA PURITY C Quell ST C500 replacement cartridge, MPN 1002045. A compatible PURITY C filter head is required and is not included. Replace the cartridge at its calculated capacity or no later than 12 months after commissioning.
* Rated capacity at 30% bypass, 180 ppm carbonate hardness (10°dH). Actual capacity varies with local water hardness, bypass setting and application.
Follow the manufacturer’s installation guidance and check all connections before leaving the installation.
