Typical applications
Regal Twin 3672 in Saudi Arabia
Large Saudi sites on a groundwater blend can't afford scale in boilers or process lines, and can't shut the water off to regenerate. The Twin 3672 avoids both.
Its WS2CE 2-inch valve alternates the two vessels, and up to six units can run on one controller as demand grows.
Common questions
Is it for 24/7 sites?
Yes. It is designed for sites that run day and night, like hotels, hospitals and process plants.
How much soft water can it supply?
18.2 m³ an hour, without interruption.
Can it feed an RO plant?
Yes. Softening the feed protects RO membranes from scale on hard supplies.
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.
