The coffee machine RO system Oman cafés, offices and restaurants use to keep espresso tasting right and boilers free of scale. This is our CAF-3 package: a 100 GPD reverse osmosis unit with an 11-gallon pressurised storage tank, remineralisation and a booster pump, sized for a one or two-group espresso machine plus an ice maker on the same line.

Muscat mains water reaches most cafés at 250-600 ppm TDS with hardness between 120 and 300 ppm as CaCO3. That scales a heat exchanger within months and strips flavour from the cup. This system brings the feed water down to roughly 50-90 ppm TDS and then blends minerals back in, landing inside the Specialty Coffee Association brewing water range.

Coffee machine RO system Oman: features and benefits

100 GPD membrane — around 380 litres per day, enough for a busy counter with headroom for peak-hour demand.
11-gallon pressurised tank — roughly 42 litres of storage, so the machine never waits for the membrane during a morning rush.
Remineralisation stage — puts back controlled hardness and alkalinity. Unmineralised RO water tastes hollow and pits copper boilers.
Booster pump — holds output steady where counter-level inlet pressure drops below 2.5 bar, common in older Muscat buildings.
Two carbon stages — removes the 0.2-0.5 ppm free chlorine in municipal supply that attacks group-head seals and flattens aroma.
Pressure gauge and TDS monitor — you see the filter fail before the barista tastes it.
Fits under the counter — compact frame, food-grade tubing, quick-connect fittings.

Applications

This coffee machine RO system Oman package is specified for sites running Muscat mains water, and every unit is commissioned against an on-site water test rather than a generic setting.

Specialty coffee shops, restaurant and hotel F&B counters, office pantries, petrol station cafés, bakeries, and any site running an espresso machine, ice maker or combi oven on Muscat mains water.
