General description

Oxygen Scavenger Plus is a catalysed, liquid solution of Diethylhydroxylamine (DEHA). Its volatile properties ensure distribution throughout the boiler and condensate system, and hence protects against oxygen corrosion in all parts of the system. The product also provides the required conditions for the establishment of a passivating layer of magnetite on all metal surfaces. Oxygen Scavenger Plus is a low toxicity product, suitable for high, medium and low pressure boiler systems.

Features

Fast acting, volatile, liquid oxygen scavenger

Neutralises acids occurring in condensate system

Safe and easy to use, low toxicity

Organic product, no dissolved solids added

Simple test to determine treatment level

Benefits

Economical in use

Reduces corrosion of iron and copper, increasing system life and reliability

Protects system metals throughout the boiler system

Directions for use

Oxygen Scavenger Plus can be used in any boiler system, and in conjunction with mechanical deaeration systems.

Removal of dissolved oxygen is vital for prevention of corrosion and especially pitting corrosion in boilers. When

dosed into a boiler system, Oxygen Scavenger Plus will react with dissolved oxygen and form non corrosive

compounds. The product is volatile and will evaporate and assist protection of the steam and condensate system.

No solid materials are produced when using Oxygen Scavenger Plus.

Dosing method

Wilhelmsen Ships Service recommends continuously dosing into the boiler feed line using an automatic dosing unit.

Dosage and control

Dosing should be controlled so that the DEHA residual in the condensate is between 0.08-0,30 ppm. The

consumption will depend on feed water temperature and the amount of water fed into the boiler. For more

information about initial dosage and dose rate please consult your nearest Customer Centre.

Sampling and testing

A representative sample of Condensate should be drawn for analysis daily. The sample should always be taken from

the same sampling point, cooled and tested immediately. Follow the WSS test kit instructions and log the results in

Waterproof. The results should be sent to WSS as stated in the Waterproof instructions.

It is important that regular testing is carried out, to ensure the correct level of treatment is maintained.
