How Can UV-C Help Control Airborne Microorganisms in Food Processing Facilities?

Airborne microorganisms can be a concern in food manufacturing environments, particularly where exposed products, equipment, or packaging require careful hygiene management.

Ultraviolet-C (UV-C) treatment provides a way to inactivate susceptible airborne microorganisms when they receive a sufficient dose of germicidal UV radiation. Depending on the system design, UV-C can treat recirculating room air, air moving through ventilation systems, or selected surfaces within air-handling equipment.

American Air & Water® supplies commercial UV air-treatment solutions for industrial and commercial applications. Our offerings include Nuvonic UVpro systems and other UV technologies suited to specific air-treatment requirements.

Which UV Air-Treatment Systems Are Available?

The right system depends on the size of the space, airflow, installation requirements, and the treatment objective.

1. UVpro V-Series: Recirculating Air Treatment

The Nuvonic UVpro V300, V500, and V1000 air-treatment systems are designed for continuous UV-C treatment of recirculating air in suitable industrial environments.

These stainless-steel systems can be installed in new facilities or retrofitted into existing spaces. Potential applications include food production rooms, ripening rooms, storage areas, and large indoor spaces.

The V-series models differ in their specifications and treatment capacities. System selection should reflect the room, airflow requirements, and intended application.

2. UVpro Flange Module: Air Ducts and Industrial Equipment

The Nuvonic UVpro FM Flange UV Module is designed for integration into suitable industrial installations, including air-handling systems and ventilation ducts.

Its stainless-steel construction and IP68-rated design also make it suitable for specified applications involving water storage tanks, basins, and process equipment.

The flange module is an option when a facility needs a UV emitter integrated into an existing or new equipment installation rather than a standalone recirculating air-treatment unit.

How Does UV-C Air Treatment Work?

UV-C radiation can inactivate susceptible microorganisms when they receive an adequate dose.

For airborne treatment, effectiveness depends on several factors:

A lamp's electrical wattage alone does not establish the microbial reduction that a system will achieve in a particular room or ventilation installation.

Proper selection requires matching the equipment to the facility's airflow and treatment requirements.

Where Can Industrial UV Air Treatment Be Used?

Potential applications include:

The appropriate configuration depends on the system's intended use, the facility's requirements, and the manufacturer's installation specifications.

What Are the Benefits of UV-C Air Treatment?

Additional airborne microbial control: Properly designed systems can inactivate susceptible airborne microorganisms in the treated airflow.

Integration with existing facilities: Certain systems can be incorporated into new installations or retrofitted into suitable existing spaces.

Continuous treatment: Systems designed for continuous operation can treat air while operating within their specified conditions.

No chemical disinfectant applied to the air: UV-C treatment uses germicidal radiation rather than applying a chemical disinfectant to the treated air.

UV-C air treatment complements rather than replaces appropriate ventilation, filtration, cleaning, and other facility hygiene measures.

Frequently Asked Questions

Can UV-C disinfect air in a food-processing facility?

Yes. Properly designed UV-C systems can inactivate susceptible airborne microorganisms when the required UV dose is achieved. Performance depends on the system, airflow, exposure, and operating conditions.

What is the difference between a recirculating UV air system and an in-duct UV system?

A recirculating system draws room air through a treatment unit and returns treated air to the space. An in-duct system treats air moving through a ventilation duct. The best option depends on the facility and the treatment objective.

Can UV air treatment replace air filtration?

UV treatment and filtration perform different functions. They can be complementary components of an appropriately designed indoor-air management strategy.

Can UV-C treat cooling coils as well as air?

Certain UV systems are designed to irradiate selected surfaces inside air-handling equipment. Suitability depends on the system's design, installation geometry, and operating conditions.

Which UV air-treatment system is right for my facility?

The answer depends on room size, airflow, installation space, operating conditions, and the required treatment performance. American Air & Water can help identify suitable options.
