Reverse osmosis for kitchens, clinics and plants.
On the coast, Nama's desalinated water is already low in minerals, but it changes in building tanks and pipes. Inland, a well can be hard enough to scale a machine in months. Reverse osmosis gives your equipment the same water from either source. Systems run from 60 L/h for a coffee counter up to production plants.
Coffee counter, hotel kitchen or production line.
Tell us the litres per hour you need at peak. Then we look at the feed, Nama mains, a tank or a well, and pick the model.
Coffee bars & small sites
Compact units for a back bar or office pantry. The Noble RO 60 feeds espresso machines and steam ovens; the Imperial RO sits under the counter and connects over Wi-Fi.
- 60 or 120 L/h
- Adjustable final TDS on the Noble RO 60
- TFT display and Wi-Fi on the Imperial RO
- Fits a narrow back bar
Hotel and hospital kitchens
More output for hotel kitchens, banquet halls and ice machines, in a compact stainless frame.
- 185 L/h to 400 L/h
- 0.1 micron filtration on the Majestic RO
- 92 to 95% rejection on the Majestic 400
- Leak alarm and shut-off on the Majestic RO
Production & process water
Skid-built plants for bottling, food factories and manufacturing, designed for your feed, including hard groundwater from a well.
- Up to 56 m3/h
- Up to 99% TDS rejection
- Stainless skid built for the site
- Optional remote monitoring
Five systems, coffee bar to factory.
Every system, side by side.

Three stages, the same water every hour.
A pump pushes water against a membrane so fine that dissolved salts can't pass. The clean water goes on to your equipment; the salts are flushed to drain.
Pre-filtration
Sediment + carbonBefore the membrane, sediment and carbon cartridges remove silt, rust and chlorine from the tank or well.
- Silt and tank rust
- Chlorine
- Musty taste and smell
Why it matters: A clean feed means a longer membrane life.
Membrane
Where purifying happensPump pressure drives water through the membrane. Dissolved solids stay on the other side and leave in the reject line.
- Total dissolved solids (TDS)
- Hardness from well water
- Other dissolved salts
Why it matters: Your machines see steady water, whatever comes in.
Monitoring
Screens and alertsEach model checks itself in its own way. The Noble RO 60 holds a set TDS, the Imperial RO reports over Wi-Fi and the Majestic RO flags leaks and filter changes.
- Conductivity and output quality
- Filter change dates
- Leaks and flooding
Why it matters: You know about a fault before the espresso does.
Some feed water always leaves with the rejected salts. The Majestic 400 RO runs at 50% recovery, so we plan your supply and drain before installation.
Better results and fewer repairs.
Easier on equipment
- Longer life for espresso machines and ovens
- Cleaner ice machines
- Fewer breakdowns at busy times
- Less time lost to descaling
Steady every day
- Coffee that tastes the same
- Clear ice
- Reliable process water
- TDS you can set on the Noble RO 60

Sized to what you use, not oversized.
A cafe in Qurum and a bottling line in Sohar need very different plants. We size each one to your litres per hour and to the water you start with.
- Sized to your feed and your peak hour
- Pre-filters chosen for tank and well water
- Pairs with Regal softening and SovSafe UV
- Maintenance plan from a fixed annual fee

Sovereign RO in Oman
Oman gives an RO system two very different jobs. On the coast, the desalinated mains water is already soft, but it picks things up in pipes and tanks. Inland, groundwater can be very hard: a 2024 Al Dhahirah study found average hardness of about 659 mg/l.
Either way, reverse osmosis gives cafés, hotels and production lines one steady, clean base for coffee, ice and steam. We size it from 60 L/h up to 56 m³/h, and our partner team installs it across Oman.
Common questions
Is RO worth it if our water is desalinated?
Often, yes. The water is clean when it leaves the plant, but tanks and pipes can add taste and sediment. RO takes that back out, and a remineraliser can then set the taste.
What about hard well water inland?
RO removes most dissolved solids, hardness included. On very hard water we usually soften first, which protects the membranes.
Who services the system?
Our partner team, on a service plan with planned filter changes, priced in rials.
Specified, installed and looked after anywhere in Oman
Coastal mains water is mostly desalinated seawater. It is soft, but it picks things up in pipes and tanks. Inland wells can be very hard: one 2024 study of Al Dhahirah groundwater found an average hardness of 659 mg/l.
Say which governorate you are in, whether the water comes from the Nama network, a tank or a well, and what you need it for. We design the system, price it in rials and arrange the fit.
