BEFORE & AFTER
Healthy Buildings Start With Cleaner Air
UVC Solutions for Museums & Art Galleries
Protect the Environment. Protect the Collection. Protect the People.
The Challenge
Museums and Art Galleries operate in a unique indoor environment where people, preservation, environmental control and building performance all need to coexist.
The Opportunity
HVAC systems play an important role in maintaining temperature, relative humidity, ventilation and air quality. ASHRAE's dedicated guidance for museums, galleries, archives, and libraries recognises the HVAC systems must consider both occupant requirements and doing-term preservation of cultural collections. It identifies filtration, ventilation, moisture control and microbial risks - including mould - as important considerations.
AirTechnologies NZ proposes the integration of 254nm UVC technology within appropriate HVAC systems and air-handling equipment as an additional layer of environmental and microbial control.
The Solution Is Designed To
Reduced airborne biological contaminants passing through treated HVAC air streams
Reduced microbial growth on HVAC coils and internal components
Support mould-management strategies
Improve HVAC hygiene and support indoor air quality
Help protect staff and visitors from biological contaminants
Reduce the potential for HVAC systems to become reservoirs for microbial growth
Complement exisiting filtration and ventilation startegies
Improve heat-exchange performance where coil fouling is reduced
Provide an additional layer of protection without introducing UVC exposure into occupied collection areas
CREATING HEALTHIER ENVIRONMENTS
The Solution: In-duct UVC Technology
UVC light fixtures are strategically positioned within the ductwork or air handler of the HVAC system. This ensures maximum exposure of the circulating air to the germicidal effects of UVC light, effectively eliminating airborne pathogens.
How UVC Works
Continuously irradiating coils, drain pans, and air streams
Preventing microbial growth (mould, bacteria, viruses)
Keeping heat exchange surfaces clean and efficient
Improving air hygiene as air circulates through the system
Depending On The HVAC Configuration, UVC Can Be Installed Within:
Air handling units (AHUs)
Supply and return air systems
Fan coil units
Heat pump systems
Ductwork and mechanical plant
Mould & Microbial Risk
Museums can contain large quantities of organic material that may be vulnerable to mould -
Paper
Wood
Textiles
Books
Canvas
Leather
Natural history specimens
Archival materials
What Mould Can Cause
Staining and discolouration
Material degradation
Odours
Structural deterioration
Permanent collection damage
Return on Investment That Goes Beyond Clean Air

Improve HVAC Efficiency & Reduce Energy Costs
Cleaner HVAC systems can work more efficiently.
AirTech UVC systems help prevent the build-up of mould, bacteria and biofilm on HVAC coils and internal components, helping maintain clean heat-transfer surfaces and consistent airflow. By keeping your HVAC system cleaner, UVC can support more efficient operation, reduce the strain on equipment and help minimise unnecessary energy consumption over time.
For commercial buildings, this can contribute to lower operating costs, improved HVAC performance and a longer equipment lifespan — making UVC a smart addition to an energy-conscious building strategy.
Cleaner systems. Better performance. Smarter energy use.
Indoor Air Quality Benefits
The People
Improved indoor air quality
Additional control of airborne microorganisms
Reduced biological contamination in supply air
Improved perception of indoor environmental quality
Support for healthier public spaces
The Collection
Additional microbial-control layer
Support for mould-management strategies
Reduced microbial contamination within HVAC systems
Reduced risk associated with contaminated air-handling equipment
Support for collection preservation strategies
Sustainable and Environmentally Friendly
Unlike chemical disinfectants, UVC light does not produce harmful by-products or contribute to antimicrobial resistance. Its use in air purification systems reduces the need for harsh chemicals, creating a healthier and more environmentally friendly indoor environment for patients, staff, and visitors.
Cleaner Coils - UVC prevents biofilm accumulation on heat exchange surfaces, maintaining optimal thermal efficiency.
Lower Energy - Clean coils transfer heat more efficiently, reducing HVAC energy draw - typically 10-25% improvement in coil efficiency
Less Chemical Cleaning - Reduced frequency of chemical coil cleaning interventions, lowering chemical use, water consumption and contractor costs
Lower Lifecycle Costs - Extended service intervals, delayed capital replacement, and reduced maintenance spend across the HVAC asset lifestyle
Collection Protection & UVC Safety
AirTech's UVC systems are specified as enclosed HVAC treatment systems. The UVC source is contained within the mechanical system rather than being installed as exposed UVC lighting in occupied exhibition spaces.
Our Commitment
No UVC irradiance will be permitted to reach occupied areas or collection surfaces. Installation incorporate appropriate shielding, enclosure, interlocks and verification in accordance with the equipment design and applicable electrical/safety requirements.
UVC is confined within the HVAC system
Collection materials are NOT exposed to UVC
Occupied spaces receive only treated air - not UVC irradiance
Safety interlocks precent UV exposure during maintenance access
UV-inhibiting baffles are standard on all units
Tested. Verified.
Built For Real World Applications.
