Typical applications
Majestic 400 RO in the UAE
Large hotel kitchens and banqueting operations in the UAE need a lot of consistent water for ice machines and cooking. The Majestic 400 delivers up to 400 litres an hour while staying compact enough for a plant room.
It recovers 50% of the feed water, so plan drainage for the other half. On soft Dubai mains its role is a steady, clean base; on tanker or well water it also takes the extra hardness out.
Common questions
How much water goes to drain?
It runs at 50% recovery, so roughly half the feed water carries the rejected solids away. We size drainage into the install.
Can we monitor it remotely?
Yes. It has an onboard display and a connected app, so your facilities team can check it without going to the plant room.
What power and space does it need?
220 V at 500 W, and a footprint of 220 × 550 × 440 mm. It weighs 30.1 kg.
Supplied, fitted and serviced in the UAE
UAE mains water is desalinated and fairly soft: DEWA reports a typical hardness of 60.7 mg/l in Dubai. Most problems start in building tanks and pipework, so filtration and UV usually matter more here than softening.
Tell us whether the building runs on mains, tanker or well water, and what the system is for. We specify it, quote in dirhams and fit it.
