Typical applications
Regal Twin 3672 in Oman
Big hotels and hospitals run hot water day and night. On hard inland water, a single softener's regeneration break is a gap they cannot afford, and the twin layout closes it.
Each vessel has its own 570-litre brine tank. A 2-inch WS2CE valve switches the flow between them automatically.
Common questions
Does the supply stop while it cleans itself?
No. One vessel keeps softening while the other regenerates.
Can we link more units?
Yes, from two up to six on a single controller.
What does it weigh?
Around 280 kg dry, or 140 kg for each vessel.

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.
