Boiler water treatment that starts in the make-up.
Seven treatments covering make-up and feedwater, the boiler drum and the condensate return. Formulated and batch-tested in our own plants in Fujairah and Athens.
What are you treating?
Why it matters
Boiler water is the cheapest thing to get wrong.
Make-up water carries hardness, dissolved oxygen and whatever your softener let through. None of it announces itself. The first sign is a fuel bill climbing for no stated reason, or an unplanned shutdown.
Scale
A millimetre on a heat transfer surface costs fuel on every hour of production.
Oxygen
Dissolved oxygen pits the feed line and the drum from the inside.
Alkalinity
Too low and the water turns acidic, and hardness salts stay in solution instead of dropping out.
Carbonic acid
Condensate returns thin from the inside, and you lose the cheapest feedwater you have.
Sheran manufactures seven boiler water treatments at its own plants in Fujairah and Athens.
The range
Seven treatments. Two ways to run the programme.
Showing 7 of 7
1 / 7
Boiler Treat Combi
Alkalinity, scale, corrosion, sludge and condensate protection in one drum, for boilers up to 35 bar
Dose
0.4 L per m³ of boiler water, then test P-alkalinity
BWT-One Shot
Complete low-pressure programme. Dose, circulate, then hold P-alkalinity at 100 to 200 ppm
Dose
1.0 L per 1,000 L of boiler water
Boiler Hardness Control
Hardness leaking past the feed system and scaling heat transfer surfaces
Dose
20 to 80 mL per tonne of feedwater
Alkalinity Control
Boiler water turning acidic, hardness salts not dropping out, silica starting to deposit
Dose
200 mL per tonne of boiler water
Oxygen Control
Dissolved oxygen pitting the feed line and boiler. Catalysed sulphite, effective at low dose
Dose
80 mL per tonne, sulphite residual 20 to 30 ppm
Oxygen Scavenger
The same job without adding dissolved solids. For high-pressure boilers, feedwater and condensate lines
Dose
22.5 mL per 1,000 L of boiler water
Condensate Control
Carbonic acid thinning the condensate return. Neutralising amines that travel with the steam
Dose
0.25 L per day per 10-tonne steam system

Where it acts
Every stage of the steam circuit.
From make-up to condensate return, each treatment works at a different point. Dose where the problem is.
Make-up, feed tank and hotwell. Hardness, dissolved oxygen, softener performance.
Boiler Hardness Control
Oxygen Control
Oxygen Scavenger
Mechanical oxygen removal. Scavengers deal with what is left.
Oxygen Control
Oxygen Scavenger
Drum and heat transfer surfaces. Alkalinity, scale, sludge, silica.
Alkalinity Control
Boiler Hardness Control
Boiler Treat Combi
BWT-One Shot
Amines carry over with the steam to protect what comes next.
Condensate Control
Oxygen Scavenger
Return lines and feed system. Carbonic acid attack.
Condensate Control
Oxygen Scavenger
Boiler Treat Combi
Suitable for low, medium and high pressure steam boilers, hot water and process heating systems, and economisers.
Common questions
Dosage, testing and pressure.
If the boiler runs below 35 bar and nobody on board wants to manage four dosing lines, Boiler Treat Combi or BWT-One Shot does the whole job. If you need to move one parameter without moving the others, such as raising alkalinity without adding sulphite, dose them separately.
Test, do not estimate. Hold P-alkalinity between 100 and 200 ppm, sulphite residual between 20 and 30 ppm, and watch chloride trending against your blowdown. Every dose figure on this page is a starting point, to be corrected by the first test result.
Good enough that Boiler Hardness Control is topping up a working softener, not replacing one. If hardness is breaking through consistently, the softener is the problem and no dosing rate will hide it. Send us your make-up analysis and we will tell you which of the two it is.
Yes. Send a sample with the working pressure and daily steam load and we will return the analysis with a dosing programme against it. We also supply test kits so your own team can hold the control limits between checks.
All seven are supplied in 25 litre containers. Boiler Hardness Control is also available in 200 litre drums.
Order
Tell us the boiler, we will tell you the programme.
Send the working pressure, the daily steam load and your last water analysis. We will come back with a dosing programme and a price, usually within one working day.
