Choosing the Right UV-C Application​
​
We provide UV-C solutions that support cleaner air, stronger HVAC performance, and more effective building operations across commercial, healthcare, education, government, residential, and other facility environments. Our focus includes in-AHU UV-C, upper-air UV-C, surface-focused applications, and practical guidance to help clients choose the right approach for their space.
​
UV-C is not one-size-fits-all. The right solution depends on the environment, the way the space is used, the HVAC conditions, the occupancy, the system configuration, and the objective of the project. Factors such as airflow, access, safety considerations, and equipment layout all play a role in determining what makes sense and what does not.
​
We help evaluate those conditions so you can move forward with more clarity and less guesswork. Whether the need involves coil treatment, in-duct or in-AHU application, upper-air UV-C, or a residential system, the goal is to identify a solution that fits the space properly and supports the intended use. When the application is matched correctly to the environment, the result is a more practical, more credible, and better aligned UV-C strategy.
On-Coil UV-C Solutions
Upper-Air UV-C Solutions
Cleaner Air Starts at Your Air Conditioning System
Bring proven UV-C technology into occupied spaces where cleaner indoor air matters most. Upper-air UV-C is used in environments where people gather, work, learn, and receive care, with proper application, fixture placement, and room conditions all playing an important role in performance.
Enhance and safeguard HVAC coil performance using UV-C specifically created to minimize buildup on coil surfaces, promoting cleaner operation over time. coils can boost airflow, ensure effective heat transfer, lower maintenance needs, and contribute to improved overall system efficiency.
Upgrade What you Already Own
Integrate UV-C directly into your existing air handling units to restore coil performance, improve airflow, and reduce energy consumption. By continuously irradiating the coil surface, UV-C limits the accumulation of biofilm, mold, and other microbial growth that degrade heat transfer and restrict airflow.
​
Maintaining a cleaner coil helps stabilize system performance and supports better indoor air quality by reducing biological loading within the HVAC system. As air passes through a cleaner, less contaminated coil section, there is less opportunity for microbial material to enter and circulate through the occupied space.
​
UV-C exposure within the air handling unit also contributes to the reduction of microorganisms moving through the system. This includes viruses and bacteria associated with respiratory illness, such as influenza and similar airborne pathogens, helping lower the overall biological burden in the airstream.
Clean the Air People Share
Valkr Ray UV Solutions upper air UV-C systems are designed for targeted in room air disinfection in occupied spaces. Installed high in the room, these fixtures treat air in the upper portion of the space while keeping UV, C energy controlled below in the occupied zone.
​
As room air naturally circulates into the upper disinfection zone, airborne pathogens are exposed to UV-C and treated where the system is intended to operate. This makes upper air UV-C a strong option for classrooms, offices, waiting areas, healthcare settings, and other shared indoor environments that need continuous air treatment during normal occupancy.
​
Upper air UV-C is intended for airborne pathogen reduction in occupied spaces. It is not a general surface sanitizing system for the occupied zone and does not replace routine cleaning and surface disinfection practices.
Residential UV-C Solutions
Poor indoor air quality in homes can result from airborne dust, biological contaminants, VOCs, weak airflow, and everyday activity inside the house. In-duct and air-handler UV-C systems offer a broad whole-home approach because they work inside the HVAC system where air already moves and circulates.
Surface Protection for Unoccupied Spaces
UV-C can be applied in unoccupied spaces where the goal is direct treatment of exposed surfaces and high contact areas during controlled operating periods. These applications are best suited for rooms that can be treated while empty, with fixture placement, exposure path, surface layout, and room conditions all playing an important role in overall effectiveness.

​
Installed at the air conditioning unit and within the HVAC air path, UV-C helps support cleaner indoor air by treating moving air inside the system and helping control biological growth on coils and in the drain pan. The PDF also ties this approach to reduced odors, less coil fouling, lower maintenance, and better energy performance over time.
​
Because this approach uses your existing HVAC system to treat and distribute air, it offers broad coverage across the home without relying on a separate room-by-room device strategy. The source also presents this as the lowest-cost way to cover the greatest square footage while supporting both indoor air quality and HVAC efficiency.
Targeted surface-focused UV-C applications are used when a space is not occupied and the objective is to treat exposed room surfaces as part of a broader hygiene strategy. Unlike upper-air UV-C, which is designed for airborne pathogen reduction in occupied spaces, this approach is used in controlled, unoccupied environments where direct exposure to surfaces is the intended application.
​
The effectiveness of this type of system depends on more than the fixture itself. Room geometry, distance, line of sight, surface orientation, material type, shadowing, and cycle time all affect how the application performs. Because of that, the right solution should be matched carefully to the room and to the intended use.
​
When applied appropriately, UV-C for unoccupied spaces can support cleaning protocols in areas that require an added layer of controlled environmental treatment. The goal is to help clients choose an approach that fits the space properly, operates under the right conditions, and aligns with the real use of the room.
