The principle of operation of the UBR plant

UBR1 is a technological equipment with a system of filters of crud and fine filtration (HEPA filter), inside which there are bactericidal lamps that destroy harmful viruses and bacteria by ultraviolet light. The air from the premises is removed by a powerful fan, it passes through a cobble filter G4 (G7), at this stage the air is cleaned from large dust particles. Such cleaning is necessary to protect UV lamps and HEPA filter from dust and prolongs their service life. Then the air enters the sterilization chamber, where the UV lamps and HEPA filters (special fine filter class H 14) are located. The process of disinfection of the air mixture from viruses and microbes is effected there. 

The air flow passes through HEPA – a filter that traps harmful viruses, microorganisms, bacteria and particles in the air, leaving them in the decontamination zone under the influence of ultraviolet light. The purified air after the filter enters the clean air chamber and returns to the room through the distribution screen. To turn on the UBR1, press the green button on the control panel. To stop the filter unit, press the red button on the control panel. UBR1 consists of a pre-cleaning chamber, a sterilization chamber with filter elements and UV lamps, a clean air chamber with a fan with high suction power and high efficiency, located in a soundproof housing. Ultraviolet lamps are inside the case, in an enclosed space that does not let the UV rays pass. Therefore, the use of such devices is not associated with the risk of burns or injuries for the eyes.

EN 1822

The standard applies to high-performance and very high-performance ultra-low penetration air filters used in ventilation and air conditioning, as well as in technological processes such as “clean room technology” or the pharmaceutical industry. It establishes a procedure for determining the efficiency based on a method that counts the particles using a test liquid aerosol (or, alternatively, solid), and can classify these filters in a normalized way depending on their effectiveness.

The principle of operation of the HEPA filter

HEPA-filters are formed by a system of filaments of complex shape. Typically, fiberglass filaments with a diameter of 0.5 to 2 mcm are used. The main factors influencing the work are the diameter of the filaments and the thickness of the filter. The air space between the filaments of the HEPA filter is much larger than 0.3 mcm.The notion that the filter acts as a sieve, where particles smaller than the largest holes can pass through the filter is incorrect for HEPA filters. The sieve effect is also valid for HEPA filters, but it plays a negative role leading to premature contamination, reduced speed of filtration  and even filter failure. Despite the extreme undesirableness of this effect, it is almost impossible to get rid of it.HEPA filters are designed to filter small particles. These particles are captured by the fibers by the following mechanisms:
1. The effect of engagement is revealed if the air flow passes close (at a distance of the thickness of the filament or closer) to the filter fiber. The particles stick to the filaments.
2. The effect of inertia is revealed for large particles. Due to the large inertia the large diameter particles are not able to wrap around the filaments, following a curved trajectory in the air flow, and linger in one of them. Therefore, they continue to move in a straight line until they come into direct contact with an obstacle. This effect increases with decreasing space between the filaments and increasing speed of the air flow.
3. The diffusion effect is the collision of the smallest particles of contaminants with a diameter of less than 0.1 mcm, with gas particles with subsequent deceleration of the first when passing through the filter. Such particles begin to move away from the air flow lines at a distance exceeding their diameter. This behavior is similar to Brownian motion and increases the probability that the particle will stop permanently under the action of one of the above mechanisms. At low air flow rates, this mechanism becomes dominant.

The diffusion mechanism predominates for filtration of the particles with diameters less than 0.1 mcm. Engagement and inertia predominate for particles larger than 0.4 mcm in diameter. Particles with a size of about 0.2-0.3 mcm are not filtered as efficiently, they are called Most Penetrating Particle Size (MPPS). The class of the filter is determined by MPPS.

Bactericidal lamp

The bactericidal lamp effectively destroys viruses, bacteria, microbes, mould, fungi, yeast, spores and other pathogenic microorganisms. Microbes die from the absorbed dose of ultraviolet ray, which leads to the destruction of their DNA molecules and cell structure. As a result, they lose their ability to reproduce and completely lose their viability. This helps to avoid infectious infections that are dangerous to human’s health, which is especially important during epidemics of influenza viruses and the development of SARS, ARI, pneumonia.

Placement of UBR (Ultraviolet disinfector with air recirculation of the closed type) indoors

Recirculators are placed in the premises in the way to carry out the collection and release of the air without obstacles and coincide them with the directions of the main convection flows. Avoid installation of the recirculators in the corners of the premises where stagnant areas may be formed. It should be remembered that in the heating season, the heating radiators create the outgoing air flows above themselves, which then spread along the ceiling and go down beneath the opposite wall of the premise.
Do not place the recirculator near the net screens of the exhaust ventilation. In this case, most of the air treated with the sterilizator can be removed through the exhaust nets, not having enough time to spread in the premise.  The recirculator should not be placed in such a way that the outlet screen is located directly in the area where people are located, and the outgoing air flow creates uncomfortable conditions for them.

Examples of placement of recirculators in the premises with supply and exhaust ventilation, operating in normal mode, with different correlation of side lengths (length / width) are shown in Fig.1 and Fig.2.

How to use the recirculator?

Like any bactericidal recirculator, the UBR does not allow the distribution of harmful ozone into the air, so it is not necessary to ventilate the premise after its operation.Another important advantage of a closed-type recirculator is that it can be used without leaving the premise. This is especially important when using a recirculator for regular disinfection.

Where the recirculator can be used?

Since the main purpose of such devices is to clean the air in the premises, the places of their use are practically unlimited. Bactericidal recirculators of the closed type can be positioned in any place with big concentration of people and animals. These can be, for example:

• Any kind of industry enterprise;
• Kindergardens and schools;
• Medical institutions;
• Individual shops;
• Animal shelters;
• Trade and entertaining centers;
•  Shopping malls;
•  Office centers and separate large open-spaced offices;
•  Food and beverage places, restaurants and institutions.

Why it is necessary to purchase a recirculator?

There are many reasons for this:

• the device disinfects most of the known harmful microorganisms, i.e. makes the air clean and fresh;
• disinfection of the air with bactericidal devices of this type is safe for humans;
• you can be indoors while the device is operating;
• the room does not need to be ventilated after the operation of the closed type recirculator, while after recirculators with quartz lamp it is necessary to do;
• recirculator disinfects the air, so it can be considered a device for the prevention of SARS, influenza and other infections;
• the bactericidal device can work continuously as long as people are staying in the premises, etc.

The main advantages of recirculators in comparison with irradiators are:

• Possibility of use in the presence of people and animals;
• Ensuring of the high efficiency of disinfection due to repeated air circulation through the disinfection chamber;
• Possibility of use for creation of local air zones with the increased purity in rooms of large volume;
• Ensuring the reduction of air pollution not only in health care facilities, but also in the most problematic areas of production, such as: plugging and bottling lines, packaging of products, warehouses and storage areas of raw materials and products;
• Possibility of installation directly indoors regardless the general ventilation system;
• Low noise level due to the use of modern components.
