Description
The BWT bestaqua 14 ROC is a compact reverse osmosis system built for coffee shops, restaurants and hotel kitchens. It produces up to 120 litres per hour of low-mineral water, then remineralises it with magnesium through the bestaqua PREMIUM cartridge, so coffee tastes balanced and machines stay free of scale and gypsum.
Oman has high-TDS water in many areas, often with sulphate and chloride levels that a simple softening cartridge cannot handle. Gypsum scale and corrosion then damage boilers and steam wands. The BWT bestaqua 14 ROC removes the dissolved salts at source and rebuilds the water to the profile your espresso machine needs.
Features of the BWT bestaqua 14 ROC
- Up to 120 L/h permeate – serves several machines in a busy outlet
- BWT Magnesium Technology – the PREMIUM cartridge adds magnesium for flavour and scale protection
- 0.1 micron ultrafiltration in the PREMIUM cartridge – log 6 bacteria retention
- Cartridge design – membrane and PREMIUM cartridges change without tools
- Diaphragm booster pump – 230 V supply
- Optional expansion tank for peak demand

Applications
Espresso and filter coffee machines, tea stations, ice makers, combi steamers, dishwashers and refill water stations in cafes, restaurants, hotels and catering kitchens. The BWT bestaqua 14 ROC is a good choice where feed TDS is above 400 ppm or where softening cartridges fail to stop gypsum scale.
Maintenance and replacement
Change the PREMIUM cartridge every 12 months or at its rated capacity, and the membrane cartridge every 2 to 3 years depending on feed water. We replace both, check permeate TDS and set the mineral blend during service visits in Muscat.

For lower-TDS water, a cartridge filter such as the BWT besttaste or BWT bestprotect may be enough. For drinking water only, see our 200 GPD reverse osmosis system. For reference standards, see the WHO Guidelines for Drinking-water Quality.
