Typical applications
Majestic 400 RO in Saudi Arabia
Hotel kitchens, catering contractors and ice production in the Kingdom need high flow without a large plant room. The Majestic 400 gives up to 400 litres per hour from a cabinet 220 mm wide.
On Riyadh's blended supply it rejects 92 to 95% of dissolved solids, protecting ice machines and kitchen equipment from scale. Its display and app let your engineers keep an eye on it from anywhere on site.
Common questions
How much feed water does it use?
It recovers 50%, so for every litre of purified water about one litre goes to drain. Plan the drain point with us.
What feed pressure does it need?
1 to 6 bar, on a 220 V supply at 500 W.
What is the cabinet made of?
AISI 304 stainless steel, chosen for hygiene in foodservice. The unit weighs 30.1 kg.
Supplied, installed and serviced in Saudi Arabia
Saudi supply is a mix of desalinated water and groundwater. Where groundwater is blended in, as in Riyadh, the water can be hard enough to scale heaters and machines, so we check your supply before choosing a system.
Tell us your city, whether the site is on mains or tanker water, and what the system is for. We specify it, quote in riyals and install it.
