Product Data (PD) and Safety Data Sheets (SDS) are available upon request

The object for adding water treatment chemicals to a boiler installation is to prevent deposition in the feed and boiler systems, and corrosion in the feed, boiler and condensate systems.

In order for any programme to be successful, however, not only must the chemicals be correct, but also their application; it is for this reason that we consider the boiler installation. Only with the use APPLIED TECHNOLOGY will an overall water treatment package be effective.

The chemicals would allow for BS 2486 “Recommendations for the treatment of water for land boilers” to be followed and act as a standard for correct operational quality water limits. These are also recommended with the Association of Shell Boilermakers.
