Avalon Water Treatment are able to offer a full pre and post-commission chemical cleaning service for our chiller and hot water system clients to enable maximum heat transfer efficiency and uncontaminated water side conditions.

In addition, our environmental staff have designed cleaning and disinfection services specifically to meet the needs of the Legionella legislation.

legionella cleaning and disinfection
The removal of bacterially contaminated dirt and debris in hot and cold water storage systems is mandatory under the L8 guidelines and Avalon Water Treatment provides a first class bespoke service that meets or exceeds the regulations. Our environmental division always works in accordance with our own Legionella control system standards which we believe to be the highest in the industry.

The applicable regulations (L8) also specify that cooling towers and condensers need to be cleaned biannually in order to prevent the growth of Legionella bacteria. An important component of your Legionella control programme would be to have this work carried out to the highest standard and certificated for inclusion in your Legionella logbook.

Typical services include:

• Emergency disinfection and cleaning.
• Cleaning and sterilisation programmes for water systems and supplies.
• Sterilisation of interrupted water supplies.
• System monitoring and control, legionella testing, portability etc.
• System design, improvements, refurbishments and retro-fits.
• Planned, preventive legionella control systems.
• Job method statements are provided, along with relevant safety data, for each undertaking

chiller and hot water systems
A good cleaning maintenance programme for chillers will increase operating efficiency, reduce energy costs, reduce downtime and provide more reliable performance of the chiller system. The comfort of building occupants is very important and maintaining a clean chiller system will provide for greater comfort during the summer months. Equally, scale, corrosion and bacteria free water systems improve both efficiency and safety in semi-closed mould/oil cooling systems.
