The device is an air recirculator providing biological protection that is able to simultaneously carry out disinfestation, disinfection, and serve as a pest repellent. The device treats the air of the occupied room in the following sequence: air is fed through the irradiation zone with UV lamps and through the internal disinfection chamber (if a UV irradiating chamber is used) of the device. After that, the purified and disinfected air is supplied to places of work/resident/leisure to prevent an infection.
Disinfection is carried out using a combination of measures in order to achieve complete sterilization of air in the dedicated space. The device is able to be used in classrooms, gyms, cinemas, cafeterias, vehicles (including public transport), waiting rooms (including in airports and train stations), as well as larger areas, such as factories and malls, as well as any other room used for a large and long-term assembly of people.
The equipment is powered from a single-phase city network, the power consumption depends on the performance and ranges from 0.1 to 1 kW / h. An unconditional guarantee is the trouble-free operation of the equipment during the year, an extended warranty is possible with the included service.
Our offer provides the solution for continuity of public service and administration and the safety of citizens when we are in a state of epidemiological danger. By installing this product we can ensure that at least inside areas are safe and people going to work feel assured that they are protected and operate in virus-free environment and do not carry back home any danger from work.
ATTENTION: when selecting equipment operating in the recirculator mode (UV recirculators, air conditioners with UV lamps, central ventilation with UV blocks and ionizers, etc.), you need to make sure that the air disinfection unit has the proper power - for example, the UVs installed today in air conditioners lamps have a low power to destroy coronaviruses, but they can mix the viral aerosol over the entire volume of the room and contribute to the spread of infection!
]]>When it comes to improving the quality of the air we breathe, DDD Technology Corp. takes a fresh approach. We’ve challenged the conventional ways of building climatology to create innovative solutions relevant to modern needs. Our goal is to give everyone clean, pure, disinfected air in their homes and workplaces for easier breathing and better health.
We Think Differently
Our UV air purifiers are built on reliable sterilization and disinfection technologies. Such technologies are integrated into single ventilation units, giving you a multifunctional product that covers all your needs. As our devices protect against viruses, bacteria, and other pathogens, they improve health, wellbeing, and productivity.
We design our devices to effectively remove allergens and harmful microbes from the air. This ensures you’re protected against allergic reactions and airborne infections, including the COVID-19 virus. Our devices remove:
The result is clean air and a reduced risk of contracting infectious diseases or having your allergies triggered. When you breathe healthy air, you feel healthier too.
How Our Devices Work
Using directed air flow and ultraviolet disinfection, our devices rid the air of harmful microbes. We have various models capable of sterilizing differently-sized spaces; all are safe for use in occupied premises.
The following four tasks can be performed by our UV air purifiers:
1. Fast, effective, and continuous indoor air inactivation
Rapid, directed air recirculation (up to 15m) suppresses the formation of focal points containing high concentrations of bioaerosols, viruses (including COVID-19), bacteria, mold, fungus, yeast spores, and other infectious microorganisms. This is particularly useful in premises that people inhabit for longer periods of time, such as hospital wards, classrooms, prisons, and public transport.

2. The creation of areas with positive pressure
Such areas are safe from contamination. The treated and disinfected air is pumped into the zones of negative pressure, protecting the area from contaminated air. This is beneficial in recreation spaces, offices, and other workplaces.

3. The zoning of premises
Premises are divided into “clean” and “dirty” areas using the air flow that creates a “screen” between them. This is possible within premises or at building/street boundaries.

4. Volumetric disinfection of premises
This is achieved by supplying large volumes of the treated air at low speed, with the potential for it to be pumped back from the contaminated area to the disinfection zone. This solution is ideal for protecting people in premises with high ceilings, such as industrial workshops and retail spaces.

The Science Behind the Performance
To make such protection possible, we developed several multifunctional, compact, and modular devices. They’re designed to ensure the safety of premises and the people within them from most biological threats.
Our devices have many smart functions including
Additional modules help to sterilize the air, surfaces, and areas of the space. Disinfection is combined with sterilization to destroy both the biological pathogens and the carriers of infectious or parasitic diseases.
Our devices consist of a basic unit (one or several powerful air disinfection units), a fan and/or an air supply system for directing and concentrating the supplied air flow. There is the option to have the device fitted with a wide range of additional modules to enable it to perform the following tasks:
How Our Air Disinfection Devices Will Benefit You
Air disinfection and purification devices are multi-beneficial in homes, workplaces, and commercial premises. They can be used in many different settings including schools, gyms, movie theatres, canteens, waiting rooms, industrial workshops, and on public transport. Wherever people live, work, or congregate, our devices will keep them safe.
Conclusion:
When organizing air exchange in such a way that the decontaminated air is supplied directly to the breathing area of people in the room, and the contaminated air is displaced outside the area of the person's location, the risk of transmission of viral infections from one person to another is reduced significantly. This statement is confirmed by the research of scientists: when using protective ventilation systems, the probability of infection with measles is reduced to 2%, flu-up to 1 %. Thus, the use of protective ventilation systems in rooms with permanent locations of people (for example, in office premises) is an extremely promising engineering solution to prevent the spread of viral infections transmitted by airborne droplets.
Why is it necessary to pay attention to air purification and lung protection from SARS-CoV-2virus? For one, but good reason - a person inhales 14 kg (30.8 pounds) of air per day, and this isseveral times more than the weight of the food he consumes.
At the same time, everyone is concerned about the quality of the products, but they only remembered about air safety duringthe COVID-19 epidemic.
Our main protector is our Sun, whose ultraviolet radiation destroys seasonal outbreaks of flu and other infections. But as the experience of the COVID-19 epidemic has shown, the most effective measures, quarantine, do not allow the use of this blessing granted to everyone in a post-industrial society. At risk were people locked up in enclosed spaces: houses, on transport and in the workplace.
In this situation, help is provided by artificial sources of UV radiation, which quickly destroys the protein and nucleic structures of the virus from single-stranded RNA, such as coronaviruses, and a dose of 339-423 μW * s / cm² with an ultraviolet wavelength of 254 nm gives 90% - disinfection of air.
This principle is based on modern ultraviolet room sterilization carried out by UV lamps and UV recirculators. For example, a California-based company Dimer UCV Innovations has been operating in the UV disinfection of vehicle interiors since 2014, and the presence of UV disinfectors is a prerequisite for the operation of surgery rooms and blood transfusion centers in most developed countries.
However, despite the high capabilities of UV equipment, its use in everyday life, in rooms where children are located, in offices, in workplaces and in places with high traffic or prolonged stay of people, there are some restrictions: the use of UV lamps is allowed only with the absence of people during the operation of the device, and the action of the UV recirculator helps to reduce the incidence of personnel only up to 25%, in view of the low productivity (by air) of this equipment
]]>Despite the many epidemics suffered by humanity, we were not ready for the COVID-19 pandemic, where the coronavirus SARS-CoV-2, unfamiliar to our immunity, after getting intothe lungs and infecting the alveoli (without nerve endings) - leads to a prolonged asymptomaticcourse of the disease COVID-19, in the absence of any protective reaction of the body.
The COVID-19 pandemic shows a complete lack of preparedness to combat such an infectious disease. Current measures, including quarantining, social distancing, restriction of activity and movement, as well as mandatory personal protective equipment (respirators, airtight protective suits) significantly limit the freedom of citizens, damage financial security of enterprises and small businesses, and overall resulting in the destruction of the state economy.
At the same time, essential workers including the police, the military, healthcare providers, retail and restaurant employees, and continuous production workers are engaged in the process of providing basic needs and rights of the population. Those who are supporting the foundations of a civilized society are held hostage to the situation and are forced to sacrifice their health and life for the benefit of the community.
In addition, quarantine measures have their own drawbacks – those confined to certain spaces, including at home, in transit, and at the workplace, are at risk. An alarming number of infections in hospital wards and nursing homes require a radical decision to ensure the safety of the public in a post-industrial society in epidemiologically dangerous conditions.
