With the advent of bactericidal irradiators, disinfection in residential and non-residential premises has become easier. They are used both in medical institutions, various organizations, and at home. They are divided into open and closed type devices. Recyclers are closed bactericidal lamps.
Device operation
To understand why a
bactericidal irradiator-recirculator is needed
, it is necessary to understand how it works. Rays of a certain length (usually 254 nm) emanating from a lamp are capable of destroying various
pathogenic microorganisms. This helps to ensure that the air in the room becomes clean and safe for people.
Recirculators differ from ordinary quartz lamps in that they can be used in the presence of people. Their work prevents the growth of microbes in the air. This helps to reduce the spread of diseases that are transmitted by airborne droplets. They are able to destroy the viruses staphylococcus, streptococcus, parainfluenza, influenza and adenoviruses.
Principle of operation
Each ultraviolet bactericidal irradiator-recirculator consists of a closed housing, a fan and UV lamps. This design allows him to clean the room, but at the same time not have a detrimental effect on people.
During its operation, with the help of a fan, air is pumped through a closed case. It runs along bactericidal lamps and is disinfected due to the fact that most microorganisms in the air die. After that, he gets through special holes back into the room.
For high-quality disinfection of air in rooms where people are constantly located, such a lamp should function continuously.
Selection rules
The market now has a fairly wide selection of devices designed to disinfect air and surfaces in buildings. If you need a bactericidal irradiator-recirculator, then you should decide in advance in which room you will use it. The smaller the room in which he will work, the weaker the device can be.
On sale you can find both stationary and mobile models of irradiators. The first ones are mounted on a wall or canvas. The second, as a rule, are equipped with wheels for the possibility of their movement. If you need to process several rooms (cabinets), then it is better to choose a mobile bactericidal irradiator-recirculator. It is also preferable for large rooms that can be processed in stages. To do this, simply move the device at regular intervals. But for small rooms, such as wards in hospitals or doctors' offices, stationary devices are more convenient.
Types of Recirculators
If you choose an irradiator, then you need to know that they differ not only in the way they are used (stationary and mobile). The device can have from 1 to 3 lamps. Their performance is determined not only by power, but also by the speed with which air passes through their housing and is disinfected. For example, some models are able to disinfect about 30 m 3 in 1 hour, but there are also those whose productivity reaches 400 m 3 . It is important to understand that the level of energy consumption will also depend on power.
For rooms with high traffic, including patients, it is advisable to choose double-lamp devices with a high speed of air treatment. Only with a sufficiently high power, the UV bactericidal irradiator-recirculator will cope with the task. Such devices are best used in clinics, hospitals, kindergartens , schools. In offices and homes, there is no particular need for powerful recirculators. For disinfecting air in small rooms, single-tube devices are quite enough.
Modern devices are quite convenient to use. They are not only equipped with a button for turning the device on and off, but also with a display. On it you can view information about how much the irradiator has already worked. Also, some models are equipped with a timer. With it, you can set the desired mode of operation.
Device Features
Each ultraviolet bactericidal irradiator-recirculator has several advantages. This device, when used correctly and correctly, can destroy up to 99.9% of
pathogenic bacteria.Its main advantage compared to ordinary quartz lamps is that when working indoors, people, animals, flowers can be. But when the irradiators are open, it is impossible for living organisms to be in the room. In addition, recirculators do not affect furniture, modern decoration materials, and medical equipment. But they say that with pathogenic microorganisms located on surfaces (cabinets, beds, walls, tables, nightstands), they cope worse than open-type models.
Irradiator "Dezar"
Most modern recirculators install ozone-free lamps. During operation, they emit waves with a length of 254 nm. The bactericidal irradiator-recirculator Dezar, which is used in compliance with all requirements and rules, is able to prevent the spread of SARS, influenza, diphtheria, tuberculosis and many other diseases. Its main task is to maintain aseptic conditions in rooms where people are constantly located.
The productivity of the apparatus "Desar-3" is 100 m 3 / hour. At the same time, its dimensions are small. In length, its value is 890 mm, in height - 370 mm, in width - 140 mm. It is possible to use this bactericidal wall irradiator in institutions of the sphere of life and service. The recirculator can be installed in a hairdresser, beauty salon, laundry. They are also operated in kindergartens, schools, nurseries, specialized clinics and multidisciplinary clinics.
Depending on the model, Dezar is able to disinfect from 95 to 99.9% of all indoor air. The life of Philips lamps installed in fixtures is 8000 hours. The efficiency of their work throughout the entire service life is the same. It is also worth noting that special bulb lamps are capable of delaying radiation, the length of which is less than 200 nm, which means that they prevent the formation of ozone in the surrounding air.
Portable recirculators
In stores selling special medical equipment, you can find both stationary devices and devices that can be moved. Such disinfecting irradiators include, for example, Aerolit recirculators. They are designed for air disinfection; their productivity, depending on the model, can range from 200 to 400 m
3 / h. Moreover, such a bactericidal irradiator-recirculator works with an efficiency of 99.9%. It is able to disinfect not only air, but various surfaces. In addition, the operation of a portable feed is more efficient. This is achieved due to the fact that during the movement of the air is mixed.
The Svetolit Aero series recirculators come with a remote control. It allows you to control the device from a distance, set the processing time of the room and makes the device safer.
Mixed Type
Separately, it is worth noting that on sale you can find recirculators that can work like ordinary open irradiators. Their design allows you to remove a special protective screen. With this mode of operation, all safety measures must be observed: people, animals, flowers should not be in the room. After the operation of such an irradiator, it is necessary to ventilate the rooms. But it is worth noting that the bactericidal irradiator-recirculator in open mode works more efficiently.
For example, if the performance of a closed-type Svetelit Aero device is 200 m 3 / h, then without a protective cover it rises to 400 m 3 / h. Calculating the device’s runtime is easy. To do this, determine the volume of the room. If it is about 100 m 3 , then the specified recirculator for disinfection of the room is enough to work out 30 minutes, and in open mode - 15.
