Product Profile
Product Overview
Diethylhydroxylamine (DEHA) is a highly effective oxygen scavenger widely used in boiler water treatment systems for medium- and high-pressure boilers. It is supplied as a colorless to pale yellow transparent liquid and is available in two commercial grades: DEHA 85% and DEHA 98%.
DEHA removes dissolved oxygen from boiler feedwater, helping prevent corrosion, extend equipment life, and improve operational efficiency. Unlike traditional oxygen scavengers, DEHA also contributes to the formation of a protective passive film on metal surfaces, making it a preferred solution in modern water treatment programs.
Available Grades
