Internal Surface Relining of AHUs

Posted on August 22, 2012

Subjected to incessant and aggressive conditions, air handling units (AHUs) often suffer from seriously corroded internal surfaces that need to be addressed quickly and effectively to prevent possible contamination from the Legionella bacteria which could lead to an outbreak of Legionnaire’s disease (recently highlighted in the popular BBC series ‘Holby City’). At COVAC we have been offering our expertise for over 15 years and as the market leader in AHU refurbishment using solvent free polyurethane technology we can offer a reliable AHU reline and refurbish service with a long term guarantee.

As the dominant company in this industry we pride ourselves on providing our clients with long-term protection that tackles the problem of AHU corrosion. Utilising the very best and most effective solvent-free, high performance technology, COVAC can help to reline your AHU with the very best product on the market.

We often discover that the original factory condition of the internal surfaces of Air Handling Units has simply broken down over time and constant use leading to micro aquatic bacterial growth on the corroded surface and contamination to the outlet.

It is now a legal requirement that your AHU complies with the guidance of ACOP L8, and therefore using products that meet with the water regulations is a must. Our solvent free, urethane coating offers a raft of economic and safety advantages, including:

•    Resisting the growth of bacteria such as Legionella;
•    Fast curing times even when exposed to low temperatures, thus reducing downtime;
•    Highly flexible to ensure it can accommodate structural movement;
•    High resistance to chemicals and impact;
•    Offers long-term protection with little need for maintenance.

At COVAC we believe that there is no other single coating product available that can match the durability and reliability that our service offers.
