Typical applications
Regal 100 Water Softener in Saudi Arabia
Where a Saudi flat's supply leans on groundwater, scale soon shows on kettles, taps and water heaters. The Regal 100 softens the water for one household, under the sink.
Ten litres of resin give about 1.8 m³ of soft water between regenerations. Each cycle uses about 1.2 kg of salt, and the Clack valve runs on 30 W.
Common questions
Is it enough for a family flat?
For a typical flat, yes. It delivers up to 1.2 m³ an hour. Larger villas usually step up to the Regal 200.
Why does my kettle scale so quickly?
Hard water drops scale when it is heated. Riyadh's groundwater blend measured up to 281 mg/l hardness, so boiling it leaves deposits fast.
Does it need power?
Yes, a standard socket. The Clack valve draws 30 W.
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.
