Feedwater - Boiler Water Treatment Chemicals
As well as being a service company Feedwater also manufactures and supplies a range of high-quality boiler water treatment chemicals for UK and export customers. Our chemicals are suitable for land, marine and heritage steam boilers.
A badly treated steam boiler is a potential bomb, so getting the feed water quality and boiler water chemistry correct is critical and that means using tried and tested boiler water treatment chemicals.
A complete water treatment programme for a steam boiler will usually include a chemical oxygen scavenger, alkalinity builder and polymer sludge conditioner and, depending on the application, may also incorporate a phosphate treatment and a condensate line treatment.
If you are looking for chemicals only, a selection of our most popular chemicals are available for online ordering by secure checkout process.
Any treatment chemical is only as good as the service that accompanies it and we’ve been treating steam boilers for over 40 years. Our regional consultants look after hundreds of sites across the UK and are experts in the treatment of boilers and heating plants.
If you would like to arrange a free consultation with one of our experts to visit your site, we can come up with a bespoke treatment plan to increase your boiler plant efficiency, ensure the protection of your critical assets and save you money.

A chemical oxygen scavenger is used to remove the residual oxygen from the boiler feed water in order to protect not only the boiler but also control corrosion in the hotwell (or feed tank) and the condensate return lines.
Sulphite/SulfiteOur product range includes chemical oxygen scavengers based on sodium sulphite or sulfite which is fast acting, easy to test for and ideal for low-pressure boiler applications.
- Corroban 25 – FDA-approved partially neutralised sodium sulfite (uncatalysed and also suitable for chlorine removal in drinking water and RO make-up) – POA
- Corroban 26 – FDA-approved partially neutralised sodium suphite oxygen scavenger (catalysed) – Order Online
- Corroban 27 – FDA-approved highly concentrated sulphite for maximum cost-effectiveness. – POA
We also supply a range of tannin oxygen scavengers as an alternative to sulphite or sulfite chemicals for low-pressure steam applications.
TanninTannin chemicals have a number of benefits:
- Tannin’s don’t add to the boiler TDS so reduce the need for blowdown and save energy
- they have a dual corrosion protection mechanism since they not only remove the oxygen but also form a corrosion resistant tannate film on the boiler steel
- they are brown in colour so are easy to detect and test for
- they are particularly suitable for low or variable feed water temperatures and very good at protecting idle and intermittently used boilers.
Whilst often seen as a traditional boiler water treatment chemical, Feedwater tannin products use high-quality freeze-dried tannin extracts, chosen specifically for their oxygen scavenging performance and which are blended with state of the art polymer sludge conditioners and alkalinity builders.
Feedwater’ tannin products are suitable for most low-pressure boiler applications and particularly popular with operators of steam engines, locomotives, traction engines and heritage steam boilers.
