Sceptre DS130 Dosing System
A complete dosing station for UAE plant rooms, built on a Grundfos DDC 6-10 pump with a 130 litre tank. It doses antiscalant ahead of RO on well or tanker supplies, or minerals and pH correction after it.
What it does.
- Grundfos DDC 6-10 solenoid metering pump, accurate across a logarithmic control range
- 130 L chemical tank sized for monthly rather than weekly refills
- 0 to 150 injections per minute, constant or flow-proportional
- Proportional option includes a DN 40 pulse-output water meter
- Graphic display with text menu: set the dose, no dial guessing
- Surge and overvoltage protection built in
Typical applications
Sceptre DS130 Dosing System in the UAE
UAE mains water is desalinated and fairly soft, with total dissolved solids around 254 mg/l in Dubai. RO takes it lower still, so many drinking and coffee systems add minerals back to get the taste and balance right.
On sites fed by tanker or wells, the job flips: water can be far harder than the mains, and an antiscalant protects the RO membranes. The DS130 does either, at up to 6 litres an hour, set from a text menu.
Common questions
Why add minerals to UAE water?
Desalinated water, and RO water even more so, is low in minerals. A measured dose of minerals improves taste and suits coffee and some equipment better.
Is antiscalant needed on Dubai mains?
Not often, as the mains is soft. It is mainly for RO plants running on well or tanker water, where hardness is much higher.
Can it dose in proportion to flow?
Yes. The DS130-P40 version comes with a DN 40 pulse water meter, so the dose follows the actual flow.
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.
