Description

The Culligan Aqua-Cleer Slim is a direct-flow reverse osmosis system built for cafés, restaurants and offices in Oman that need consistent, low-mineral water for coffee, espresso and ice. Water is produced as you draw it, so there is no storage tank to run dry halfway through a busy morning service.

The Culligan Aqua-Cleer Slim was designed for exactly this problem. Muscat and most of the Sultanate run on high-TDS groundwater blended with desalinated supply. That water scales coffee boilers, clouds ice cubes and flattens extraction. Reverse osmosis brings the feed down to a stable, repeatable quality so every shot pulls the same way, every day.

Why the Culligan Aqua-Cleer Slim suits Oman water

Reverse osmosis is the highest level of filtration available for drinking water, and it is the only practical way to control dissolved salts at the tap. The Aqua-Cleer Slim applies it in a cabinet just 110 mm wide, which is what makes it usable in a real café counter rather than a plant room. An integrated pump supplies up to one litre per minute on demand, for as long as you keep drawing.

Features and benefits

  • Direct-flow production on the Culligan Aqua-Cleer Slim — RO water on demand, with no tank and no recovery wait between batches.
  • Coffee-grade water quality — bacteriologically sound water balanced for specialty coffee preparation.
  • Slim 110 mm footprint — fits under a counter or in a service cupboard where a conventional RO set will not go.
  • Culligan Pure ultrafiltration option — a bacterial barrier tested by the University of Bologna, in materials compliant with DM 174/2004 and DM 25/2012.
  • Made in Italy — built to European drinking water equipment standards.
  • Protects your equipment — less scale means fewer boiler descales, longer element life and less downtime on espresso machines and ice makers.

Where the Culligan Aqua-Cleer Slim is used

  • Specialty coffee shops and espresso bars
  • Restaurant and hotel ice machines
  • Office coffee stations and pantries
  • Bakeries and juice bars
  • Villas and apartments where under-counter space is tight

Culligan Aqua-Cleer Slim installation and maintenance

  • Under-counter or cupboard mounting, with front clearance for cartridge changes.
  • Pre-filter and membrane replacement on a scheduled interval set from your feed water TDS and daily volume.
  • This is a drinking water treatment device and needs regular periodic maintenance to hold its rated performance.

Compare with our other commercial RO systems

For a combi oven or steamer, a non-electric unit is usually the better fit — see the 3M ScaleGard SGLP reverse osmosis system. You can also browse the full commercial RO range or the wider RO systems category for residential and industrial options.
