BEFORE & AFTER
Healthy Buildings Start With Cleaner Air
UVC Air Purification & Ozone Sanitisation
Cleaner Air. Safer Surfaces. Stronger Compliance.
Food Manufacturing Environments
Food manufacturing environments require strict hygiene control, consistent air quality, and robust contamination prevention to meet food safety standard and protect products integrity. AirTechnologies NZ provides two integrated solutions that work together to deliver continuous, automated hygiene control across both air and surface environments.
Core Technologies:
UVC Air Purification Systems - Installed within HVAC and ventilation systems to continuously reduce airborne microorganisms and improve system efficiency. Operates passively, 24 hours a day.
Ozone Sanitisation Systems - Generate odonates water on demand for cleaning and sanitising food-contact surfaces, equipment, and processing areas without heavy chemical reliance
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
Operational Benefits
Continuous airbourne contamination control across production environments
Chemical-free surface sanitisation supporting HACCP and GMP compliance
Improved HVAC efficiency and reduced maintenance burden
Reduced chemical usage, handling, and disposal requirements
A proactive, always-on hygiene strategy that works between and during production shifts
Silent operation - no impact on production activities
Annual lamp inspection and replacement only
Prevents biofilm and mould build-up on HVAC coils - improving airflow and energy efficiency
Installation Points
Within HVAC air handling units (AHUs)
Inside heat pump cassettes and fan coil units
At fresh air intake points and return air ducts
In-duct configurations for ventilation systems serving production areas
What It Eliminates in Food Manufacturing Environments
Airborne bacteria - Listeria, Salmonella, E.coli, Staphylococcus
Airborne mould and fungal spores - key contaminants in bakery, dairy, and produce environments
Airborne viruses and pathogens
Odours and VOCs from production processes
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
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.
Return on Investment That Goes Beyond Clean Air
Installing UVC technology isn't just about improving indoor air quality—it's about reducing ongoing operating costs.
By keeping HVAC systems cleaner, reducing biofilm build-up, and helping minimise airborne contaminants, Air Technologies' solutions can deliver measurable value over time.
✔ Lower HVAC maintenance costs
✔ Improved system efficiency and performance
✔ Extended equipment lifespan
✔ Reduced downtime and cleaning requirements
✔ Healthier indoor environments that can help reduce staff absenteeism
Cleaner air. Smarter buildings. Long-term savings.

Ozone Sanitisation - How It Works
Airtech's ozone systems generate ozonated water on demand, delivering a powerful, chemical-free sanitising solution directly to food processing and production environments.
Applications In Food Manufacturing
Food-contact surface sanitisation - benches, cutting boards, prep tables, utensils
Equipment sanitisation - mixers slicers, fillers, conveyors, packing machinery
Washdown areas - floors, drains, walls in production zones
Cold rooms and refrigeration unit treatment
Produce washing - removes pesticide residue, extends shelf life
High care and high-risk zone surface treatment
Food Safety & Compliance Benefits
Directly addresses Critical Control Points (CCPs) in HACCP plans
Supports GMP surface hygiene requirements
Eliminates cross-contamination risk on high-touch processing surfaces
No chemical residue risk - safe for food-contact surfaces without additional rinsing
Simplified sanitisation records - no chemical dilution logging required
Reduces time and labour cost of chemical-based sanitisation cycles
