Accepta’s new range of high performance cooling tower cleaning chemicals have been developed to offer a practical alternative to pack removal in the tower cleaning procedure outlined in paragraph 138 of the UK Health and Safety Executives Approved Code of Practice L8, where it is not practical to remove the tower packing.
Although removal of the tower pack for cleaning is regarded as best practice by the HSE, alternative methods of cleaning the tower may be considered where there are practical difficulties in doing so. The efficacy of these alternative procedures must be verified.

Product Range Description
Central to Accepta’s new product range is Accepta 2520. Accepta 2520 is a high performance foaming cleaner based on phosphoric acid that incorporates a foaming agent tolerant to acid and chlorine dioxide. An additional foaming cleaner, Accepta 2522 is a low acid version for use where corrosion may be an issue.
Accepta 2521 is a specially developed stabilised chlorine dioxide solution. It is packed in 250 ml containers and is sufficient to generate 50 ppm of chlorine dioxide when mixed with either 10 litres of Accepta 2520 or Accepta 2522, and subsequently used at 10:1 dilution rate in a foaming power washer.
Accepta 2315 is compatible with Activ-Ox Foam Cleaner and has been developed to counter the foaming properties of the cleaning products without leaving residues.
Accepta Dechlor has been selected to help neutralise both excess acidity and chlorine dioxide, allowing safe disposal of the spent cleaning solution form the tower.
