Over a period of 12 months ending April 2001, Advantica* carried out a series of independent tests on Corrosion Master at its world renowned research centre in Loughborough UK. The test objectives were as follows:

  • to test the effectiveness of Corrosion Master in reducing dissolved oxygen levels in a wet central heating system.

  • to evaluate the corrosion protection qualities with mixed metals typically found in wet central heating systems.

Dissolved Oxygen Reduction
Repeat tests confirmed that the product clearly demonstrated its ability to reduce dissolved oxygen levels from both fill water and simulated pump over conditions.

Corrosion Protection Qualities
Weight loss measurements taken from metal coupon samples (with 1mm wall thickness) in a system fitted with Corrosion Master demonstrate the material life as detailed below.

TECHNICAL DATA: Corrosion Master Products

General Product Information
Oxygen plays a central role in the corrosion of central heating systems, entering in the form of dissolved oxygen (D.O.) via tap water used for filling. As fire dies upon the removal of oxygen so the corrosion process also ceases.

Corrosion Master significantly retards the corrosion process by raising the pH and restricting the amount of D.O. in the water. Once the D.O has been eliminated the unit shuts down to be automatically reactivated upon the introduction of fresh oxygenated water. Additionally Zinc species that polarize existing corrosion cells are released into the water.

Product Life
The CM5 and CM10 are designed to continue working unattended for 5 and 10 years respectively and are supplied with an installation date Fitting Location Central heating system, closed circuit Position Fitted in flow or return of heating circuit. Power Source Not required. Fitting Instructions Supplied with packaging, available on request.

Additional Information
During the year 2000 Scalemaster submitted its Corrosion Master product to BG Technology for independent testing at its Gas Research & Technology Centre in Loughborough, UK. This world-renowned research establishment has considerable expertise in the field of corrosion. Extracts from their report are available on request.
