The core of Aeris Environmental’s intellectual property is our AerisGuard unique suite of patented Multi-enzyme and anti-microbial formulations which can be tailored to specific industrial situations.

The AerisGuard Multi-enzyme Solutions remediate and protect air-conditioning and refrigeration systems from commonly occurring bacterial and mould contamination problems.


HVAC systems protected by AerisGuard provide significantly improved IAQ for health, equipment efficiency and asset management benefits.

AerisGuard™ at work – The Air Conditioning Solution

The AerisGuard products provide a “systems” approach to maintaining a “healthy building”. By treating the coils, air-handling rooms, filters and ductwork, Aeris Environmental addresses the issue of contaminated indoor air at its source. Similarly, through a innovative approach to the treatment of the condenser water system, Aeris Environmental addresses the source of potential Legionella outbreaks. The following is an overview of the AerisGuard products:

Heat Exchange Coil Cleaning Solution

The AerisGuard Coil Cleaning product is enzyme based and targets all domestic, commercial and industrial air handling installations. The product is designed for application to cooling and heating coils “in situ” as part of mechanical plant maintenance. The cleaner strips away any existing bacteria, fungi and other contaminants also removing any pre-existing AerisGuard coatings, ensuring a clean surface for the application of the AerisGuard treatment. The product is non-corrosive and completely biodegradable.

Coil Treatment

The AerisGuard Coil Treatment product is applied “in situ” to cooling and heating coils after they have been cleaned and existing biofilm removed. The treatment leaves a thin coating on the coil surface. The product is formulated to release a small amount of the active biocides over a period of at least 12 months after which time the AerisGuard Coil Cleaner is used to remove the existing coating and the treatment is re-applied.


Surface and Duct Cleaning Solution

The AerisGuard Surface and Duct Cleaner is designed as the final step in source removal (physical surface and duct cleaning) and is used to ensure all contaminants are removed.

Surface and Duct Treatment

When inadequately maintained, the air handling room surfaces and air handling ducts can become colonised with bacteria and fungi. Aeris Environmental has a product for use in treating the walls, floors, ceilings of these air-handling rooms and ducts, preventing the growth of bacteria and fungi for extended periods. The product can be damp mopped or wiped onto all surfaces physically accessible and can be sprayed through the system to ensure total coverage.

Filter Treatment

The AerisGuard Filter Treatment is applied to air filters at the time of installation. The filter treatment is based on a patented technology that ensures a slow migration of a combination of active compounds into the dust particles trapped within the filter.

Dust particles provide a source of nutrients for fungi, which very rapidly colonise untreated air filters. Towards the end of its working life a typical filter is highly contaminated. Aside from the potential human health consequences, it is largely the proliferation of the fungal root system that leads ultimately to the filter becoming blocked. Application of the AerisGuard Filter Treatment dramatically reduces this fungal growth, thereby extending the filter life, improving the filter’s dust retention, reducing energy consumption and improving the quality of the building’s indoor air.

Bioactive Condensate Pan Tablet

The tablet is designed to control the build up of microbial biofilm within air conditioning drain pans and associated drain lines. The BACP Tablet has been developed as a final complementary product to the AerisGuard suite of HVAC coil and surface cleaning and residual antimicrobial treatment products. For total system protection, it is recommended that the product be used in conjunction with AerisGuard Coil Cleaner, AerisGuard Coil Treatment and AerisGuard Filter Treatment.

Water Treatment

One of the highest profile dangers to human health and safety associated with the mechanical plant of commercial buildings is legionellosis, associated with Legionella pneumophilia bacteria. These organisms proliferate in the water cooling towers of commercial air conditioning systems.

Novapharm Research has demonstrated that Legionella bacteria reside in the biofilm present on the surface of the cooling tower. The Aeris Environmental water treatment technology uses a combination of enzymes and biocides to digest the biofilm and eliminate the bulk of micro-organisms in the system.

The Aeris Water Treatment system will be available for commercial release in the near future.

OEM Coatings

Corrosion and contamination of heat exchange coils is a constant problem in air conditioning systems. Corrosion occurring between copper and aluminium can greatly reduce heat exchange efficiency especially in harsh environments like coastal areas.

AerisCoat is a water based self etching high performance epoxy resin which after only a single application can completely seal all metallic surfaces from the environment. The coating is impermeable to many of the environmental pollutants which aggressively attack and corrode metallic surfaces. The coating can either be applied during manufacture or post manufacture where it is applied on site as an after market protective coating.

Product Safety

Aeris has received an independent toxicology review from the University Analytical Laboratory at the University of NSW. The reports indicate that there is no negative impact on human health in relation to the use of AerisGuard products.

Approach to Market


Aeris Environmental’s approach to market is to train and accredit leading IAQ and HVAC service providers to apply the AerisGuard products. Aeris Environmental provides the products along with technical and marketing support. The company’s focus is on helping to build and develop the market, support its base of distributors and applicators and ensure a pipeline of new technologies to reinforce its position at the forefront of “healthy buildings”.
