UVGI Technology

Why UV-C?

Not all ultraviolet light disinfects.

• UV-A: Causes skin tanning and aging
• UV-B: Associated with skin burns
• UV-C (254 nm): Germicidal wavelength that inactivates pathogens

Myaire UVGI systems harness UV-C technology to provide safe, continuous disinfection within HVAC systems and occupied spaces.

Cleaner Air. Lower Risk.

UVGI enhances indoor air quality, reduces infection risks, and helps create healthier, safer buildings through continuous air and surface disinfection.

Surface Disinfection for HVAC

Transforming HVAC Systems into Clean-Air Assets

Cooling coils and drain pans within Air Handling Units (AHUs) are often overlooked sources of microbial contamination. Constant moisture, dust accumulation, and organic matter create ideal conditions for mold, bacteria, and biofilm growth, leading to reduced system efficiency, poor indoor air quality, and increased maintenance requirements.

The Hidden HVAC Challenge

Contaminated coils and drain pans can significantly impact HVAC performance and occupant health by:

• Reducing heat transfer efficiency
• Increasing pressure drop and airflow resistance
• Raising HVAC energy consumption
• Promoting mold, bacteria, and biofilm growth
• Contributing to poor indoor air quality and Sick Building Syndrome
• Increasing maintenance frequency and operating costs

The Solution: Continuous UV-C Surface Disinfection

Myaire’s HVAC Surface Disinfection Systems utilize continuous UV-C irradiation to disinfect cooling coils, drain pans, and adjacent surfaces inside AHUs. By preventing microbial growth at the source, the system keeps critical HVAC components clean and operating at peak performance.

• Prevents mold, bacteria, and biofilm formation
• Keeps coils clean without chemical treatments
• Operates continuously within the HVAC system
• Improves overall system hygiene and reliability

Energy Efficiency Benefits

Cleaner coils translate directly into better HVAC performance and lower operating costs.

• Restores and maintains optimal heat transfer
• Reduces coil pressure drop
• Improves airflow and cooling efficiency
• Helps reduce HVAC energy consumption by up to 10–20%
• Enhances long-term system performance

Reduced Maintenance Requirements

By eliminating biological growth, UV-C technology significantly reduces maintenance demands.

• Minimizes chemical coil cleaning requirements
• Reduces maintenance downtime and labor costs
• Extends equipment and coil lifespan
• Creates a safer maintenance environment

Improved Indoor Air Quality

A cleaner HVAC system delivers cleaner air throughout the building.

• Prevents microbial growth within AHUs
• Reduces airborne bio-aerosols downstream
• Improves indoor air quality and occupant comfort
• Supports healthier, safer, and more productive environments

Cleaner Coils. Better Air. Lower Costs.

Myaire’s Surface Disinfection for HVAC solutions help transform air-handling systems from contamination sources into high-performance clean-air assets, delivering healthier indoor environments, improved energy efficiency, and reduced operational costs.

In-Duct Air Disinfection

Continuous UVGI Protection Inside Your HVAC System

Air ducts can become pathways for the spread of airborne contaminants throughout a building. Moisture, dust, and limited visibility create conditions that support microbial growth, while high airflow velocities can carry pathogens directly into occupied spaces. Conventional duct cleaning provides only temporary relief, leaving systems vulnerable to recurring contamination.

The Challenge

Without effective disinfection, HVAC ductwork can contribute to:

• Growth of mold, bacteria, and other microorganisms
• Circulation of airborne contaminants throughout the facility
• Reduced indoor air quality and occupant comfort
• Increased health and infection risks
• Frequent cleaning and maintenance requirements

The Solution: In-Duct UVGI Air Disinfection

Myaire’s In-Duct Air Disinfection System utilizes high-intensity UV-C technology to neutralize airborne pathogens as they travel through HVAC ducts. Engineered for maximum germicidal effectiveness, the system delivers powerful UV exposure within limited air-stream contact times.

• High-output UV-C lamps for superior pathogen inactivation
• Custom-designed to match duct size, airflow, and system requirements
• Continuous operation for ongoing protection
• Prevents downstream contamination throughout the building

Key Benefits

• Neutralizes viruses, bacteria, mold spores, and other airborne microorganisms
• Reduces microbial build-up within ductwork
• Improves overall Indoor Air Quality (IAQ)
• Minimizes reliance on chemical and mechanical cleaning
• Suitable for both new installations and retrofit projects
• Low-maintenance design with long operational life

Ideal Applications

• Hospitals & Healthcare Facilities
• Commercial Offices & Corporate Buildings
• Airports & Transportation Hubs
• Hotels & Hospitality Facilities
• Educational Institutions
• Data Centers & Controlled Environments

Cleaner Air, Delivered Continuously

By disinfecting air at the heart of the HVAC system, Myaire’s In-Duct UVGI solutions help create healthier indoor environments, reduce contamination risks, and support long-term building performance.
