A Trio of Solutions to Combat Mould in HVAC Systems – Clean-Air

Mould growth within HVAC (Heating, Ventilation, and Air Conditioning) systems poses significant health risks and operational challenges. Left unchecked, mould can compromise Indoor Air Quality, leading to respiratory issues for occupants and causes inefficiencies in the HVAC System. However, modern technology offers effective solutions to tackle this problem head-on. By integrating Germicidal UVC, Ozone treatment, and Antimicrobial Coating, facilities can create a formidable defence against mould proliferation.

Germicidal UVC

Utilizing ultraviolet light in the germicidal range, typically between 200 to 280 nanometers, Germicidal UVC technology effectively destroys the DNA of mould spores, bacteria, and viruses. When installed within HVAC systems, UVC lamps irradiate the cooling coils, drain pans, and air ducts, inhibiting mould growth and preventing its spread. This proactive approach not only improves indoor air quality but also enhances the overall efficiency and longevity of HVAC equipment.

ABOVE Clean-Air® installs a wide range of in-duct UVC HVAC air duct system equipment, on-coil HVAC UV air handling systems, upper air in-room HVAC UV light systems, fixed mounted UVC packages, and other ultraviolet germicidal fixtures for numerous applications, including: commercial buildings, hospitals, clinics, dentists, veterinarians, food and beverage processing plants, schools and universities, offices, gyms, restaurants and commercial kitchens, and manufacturing sites, among many others.

Ozone Treatment

Ozone, a powerful oxidizing agent, is employed to eradicate mould and other microbial contaminants in HVAC systems. Ozone generators produce ozone gas, which is introduced into the system to neutralize mould spores, odours, and volatile organic compounds (VOCs). While highly effective, ozone treatment requires careful monitoring to ensure safe ozone levels and proper ventilation to prevent human exposure. When used responsibly, ozone treatment offers a non-chemical, eco-friendly solution for mould remediation.

This oxidisation process eliminates the third Oxygen atom that exists in Ozone (O³). What is left behind is a totally disinfected area where the only residue is clean fresh (O²) Oxygen.

Antimicrobial Coating

Antimicrobial coatings provide a protective barrier against mould, bacteria, and fungi on HVAC surfaces. These coatings contain antimicrobial agents that disrupt the growth and reproduction of microorganisms, mitigating the risk of mould infestation. Applied to air ducts, coils, and other susceptible components, antimicrobial coatings offer long-lasting protection, reducing the need for frequent cleaning and maintenance while safeguarding indoor air quality.

ABOVE The fight against biological contamination occurs at a microscopic level and requires the use of more and more advanced chemicals. We use our highly skilled Chemical Product Partners AERIS Environmental to produce cleaning, sanitising and on going treatment products to give us an edge against Mould, Bacteria and Fungi. This includes Duct Coatings and Sealants, specially designed for air conditioning and ventilation systems. They provide a barrier inside the ventilation ductwork to inhibit odour, mould and bacteria building up on the surface. Credit / lorem ipsum sit amet delor

By integrating these three technologies, facilities can establish a comprehensive defence system against mould infestation in HVAC systems. However, it's essential to note that while these solutions are highly effective, they should be implemented as part of a broader maintenance and hygiene strategy. Regular inspection, cleaning, and upkeep of HVAC systems remain crucial for optimal performance and occupant health.

In summary, the battle against mould in HVAC systems can be won through the strategic deployment of Germicidal UVC, Ozone treatment, and Antimicrobial Coating technologies. By leveraging these innovative solutions, facilities can create healthier indoor environments, improve system efficiency, and prolong equipment lifespan. Embracing technology is not just about innovation; it's about safeguarding the well-being of occupants and enhancing operational resilience in the face of microbial threats.
