Asset Management



As biofilms grow they exude exopolymers and acidic compounds.

These compounds are corrosive, especially to aluminium fins and galvanized steel components within the air handler.

The fungal contamination of other HVAC infrastructure apart from coils and filters, such as internal fibreglass duct lining and painted metal surfaces present an often unrecognised problem within these systems.

Studies by the Georgia State University and others have concluded that as fungi colonise these surfaces a range of Volatile Organic Compounds (VOC) can be produced further diminishing the supplied air quality to an occupied space.

These studies have confirmed that when fibreglass insulation materials and painted metal surfaces become colonised VOCs are created.

It was indicated that the urea-formaldehydes that bind the fibres and the acrylic-latex facings of duct liners were nutrient sources for the growth of fungi.

Secondary to the internal HVAC infrastructure degradation is the carry over of particulate generated by the evolution of bacterial and fungal growth.

Fragments of these biofilms when released into the air stream settle out in carpets, curtains and other fabrics necessitating more regular cleaning regimes and over time stain other building finishes increasing the frequency of costly refurbishment programs.

Facility Managers are empowered to maintain the operating performance and functionality of their commercial building assets – commercial HVAC assets are extremely expensive to replace, and often poorly located within large buildings adding significant time, complexity and cost to the replacement – prevention is better than cure.

AerisGuard Building Environmental Solutions provide a cost-effective long term HVAC asset protection management strategy which restores HVAC asset performance, and extends the life of the operating assets.
