With over a dozen whole room ultraviolet-C (UVC) disinfection devices on the market, determining the correct device for your facility can be a challenge.
Over 90% of these devices use 253.7nm of ultraviolet energy to perform a “no touch” disinfection treatment while other devices use a full spectrum ultraviolet energy ranging between 200nm to 320nm. Studies have shown that both types of devices are effective at eradicating pathogens on surfaces and in the air.
Devices can range in cost from $30,000 to $125,000 and by taking into consideration certain product characteristics that contribute to your operations will help you to determine what equipment best fits your needs.
Power: The first characteristic to consider during your product search is power.
Having greater power allows for a shorter treatment cycle covering larger disinfection areas, and a higher probability at disinfecting shadowed areas.
Dosage: The second product characteristic is automatic dosage verses timer dosage. Automatic devices reduce the chance of human error to determine the correct UVC dosage for a given treatment location.
Some automatic devices measure the efficiency of the emitter output during every treatment this is important to consider as the lamp output degrades over time. Automatic devices take into account the size and the reflective properties of the treatment area.
Transportation: Equipment must have robust construction and be easy for staff to move throughout the facility. Some devices include ancillary components such as plastic housing, guards, carts, or sensors that must be removed or positioned for each treatment adding unwanted labor to the treatment. UVC devices are considered environmental services equipment, not medical equipment, so it should be as easy to operate as a floor scrubber or vacuum cleaner. Equipment should also be safe and reliable by having regional safety regulatory approvals. Devices should be able to detect a component failure to avoid risking personnel and facility safety.
Functionality: Functionality and disinfection time of the device needs to be taken into consideration. Some devices have lower power and cannot reach all surfaces within treatment areas requiring multiple treatments within a single location, increasing labor costs. Other devices have a larger disinfection radius or have multiple linked devices that can treat all surfaces in a single treatment.
Operating procedures: Find a device that integrates into your record keeping system. Some computerized data collection systems will need to be implemented into your facilities information technology operating procedures.
By keeping these characteristics in mind while choosing a UVC disinfection device, you can decide what equipment is best tailored to the operations of the facility and available resources. For more information on this topic go to www.uvccleaningsystems.com.
