Questions and answers
Can the pulsed UV unit photodegrade other substances besides viruses and bacteria?
Pulsed ultraviolet light is able to destruct gaseous toxic compounds of natural and artificial origin (ester, formalin and others) by photooxidating and photodegrading them, in the same time removing any odors in the room.
How are shadow areas treated?
Shadow areas are treated by moving the unit and activating it in various points of a room (2 or more), so as to cover all existing shadow areas.
Besides, such approach allows for reducing not only the cycle duration in each specific point, but of the whole room treatment due to shorter distance from the lamp to the farthest surface to be treated (especially when decontaminating large rooms).
Does the use of the unit replace germicidal recirculators, previously installed in the room?
The units do not replace, but supplement the effect of recirculators. A pulsed unit is intended to prepare rooms for use, simultaneously decontaminating the air and open surfaces.
When a room is in use and the implementation of units is not possible, recirculators are deployed to maintain the required microbial load in the air. Which means that consecutive implementation of recirculators and pulsed UV units considerably increases the disinfection efficiency.
Is any special training required for the personnel to operate the pulsed UV units?
For operating mobile and portable units, no training is needed. All the necessary information can be found in the User’s Manual. If desired, the experts of the manufacturer or a distributor can help with a first launch of the unit, deliver a basic training, and answer any arising questions.
Stationary units are installed and put into operation by the manufacturer’s service department.
What safety measures should be taken when operating the units?
The units work in the absence of people. Before the unit launches a disinfection cycle, the irradiation indicator turns on. A sound signal and 20-seconds’ delay allow the personnel to safely leave the room to be treated.
The disinfection cycle can be interrupted by pressing the STOP button on the control panel or on the remote control. If for whatever reason somebody happens to be in the room with a working unit, the first thing to do is to protect the eyes, then leave the room immediately. This has no permanent consequences for human health.
Are there any consumable materials?
The only consumable item of the units is the lamp (lamp assembly).
How often does the lamp need to be replaced?
This strongly depends on how often the unit is used (once a day, before every surgery, once a week). The practice of usage at healthcare facilities demonstrates that for a mobile unit, the lamp should be replaced once or twice a year; for the portable and stationary units – once every 3 years.
