Sceptre DS130 Dosing System
A ready-to-run chemical dosing station for plant rooms and RO systems. A Grundfos DDC 6-10 pump feeds pH correction, minerals, antiscalant or biocide from a 130-litre tank, on a timer or from a meter.
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 Oman
Desalinated and RO water is very low in minerals, which can make it aggressive to pipework and flat to drink. Dosing a measured amount of minerals or adjusting the pH puts that right.
The DS130 arrives with its valves, level probe, hoses and a calibration cylinder. You set the dose in plain text on a graphic display, and the proportional version follows a DN 40 water meter.
Common questions
Why add minerals back after RO?
Very pure water attacks metal pipes and fittings and tastes flat. A small, measured dose balances it.
Drinking water or industrial use?
Both. It handles drinking-water remineralisation, boiler feed, cooling and cleaning-in-place.
How often does the tank need topping up?
On most systems the 130-litre tank lasts about a month, depending on the dose and the flow.

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.
