Boiler Water Treatment Chemicals Explained
Boiler water treatment protects against scale, corrosion and oxygen pitting using three chemical groups: a scale & corrosion inhibitor, an oxygen scavenger, and a neutralizing amine for the condensate.
The three groups
- Scale & corrosion: phosphonates (HEDP, ATMP) and formulated WT-503.
- Oxygen scavengers: DEHA, carbohydrazide — hydrazine-free.
- Condensate amines: morpholine, cyclohexylamine.

Frequently asked questions
Which chemical is used in boiler water treatment?
A scale & corrosion inhibitor (phosphonate or formulated WT-503), an oxygen scavenger (DEHA/carbohydrazide) and a neutralizing amine.
What is the best oxygen scavenger for boilers?
DEHA and carbohydrazide are volatile, hydrazine-free scavengers suited to low/medium-pressure boilers.
