Today’s Offices, Hotels and other buildings are generally centrally air conditioned and create its own form of indoor air pollution or commonly known as “sick building syndrome” due to nearly-air tight construction and absence of enough fresh air from outside.
Interior of modern buildings is infested with wide range of Organic and Hydro Carbon gases, released from synthetically produced interior furnishings such as carpets, curtains, ceiling tiles, paint, fabric protective coatings, clearing aids, to name few. Occupants contributed VOC are cigarette smoke, body odours, deodorant and food odors. Continuous presence of VOC, even in low concentrations, adversely affects the health of occupants. Many indoor VOC are carcinogenic or carcinogen promoters. Some irritate the mucous membranes thus VOC should be reduce significantly for safety of occupants.
Probable sources of CO2 in indoor space are exhalation by occupants and introduced by outdoor air. CO2 is neither toxic nor harmful, however it is important to ensure CO2’s concentration is not high. At elevated levels CO2 causes reduced concentration, fatigue, loss of productivity and lethargy. Regulations of ASHRAE, OSHA and internationally accepted bodies are 1,000 to 5,000 PPM.
Conditions prevalent in air handling units and air ducts such as, temperate, humidity, moisture on cooling coils and porous surface of duct lining are congenial for growth and propagation of fungi. Through air vents, they enter indoor space. Fungi cause allergies, breathing disorders, irritation and loss of concentration. Fungi provide bio adhesive force to dust and particulate contaminants to adhere duct and AHU sections. The typical discoloration seen around air vents is due to fungi.
Ozone is three-atom molecule of Oxygen with weak bonds. It is a powerful oxidizing agent & an unstable gas, which reverts quickly to diatomic oxygen or O2. Oxidation causes VOC to reduce to molecularly less stable state and lend them to further oxidation by ozone. Thus, in the presence of Ozone VOC is subject to continuous oxidation, transforming it to several transient gases. Resultant gases are totally harmless or less harmful. Total VOC is dramatically reduced. Odor is result of VOC. As VOC are removed, odor is almost completely eliminated. Net result is indoor space is a pleasant environment and no foul odour.
What is needed is a way to quickly and economically eliminate the foul smell generated by different biological sources, mustiness from mold and mildew, stale tobacco odour and other unpleasant odours.
Ozone treatment is a proven & a viable solution to purify & de-odorise air in hotels, restaurants, bars, health clubs, offices, guest rooms and other rooms. Unlike air-freshness or chemicals, “Ozone the nature’s most powerful purifying agent” does not mask the odour like deodorization sprays, but actually eliminates them through natural oxidation. It has been shown in various tests that alertness and efficiency of an individual increase appreciably in the environment of controlled Ozone.
We offering a complete choice of AQMS products which include duct mounted ozone generator, odor control ozonation system, air ascepticizer and variable load controllers.

Ozone is a very strong oxidizer and has powerful purifying property. Ozone is capable of oxidizing various organic odours and destroys viruses and bacteria present in the air, that are not only offensive but harmful as well. It has a strong potential to remove organic odour by oxidizing odour-causing molecules. Ozone converts / removes smoke (suspended carbon particles in air) to Carbon die-Oxide.
A very small and safe concentration of Ozone can purify and de-odorize air much better than any de-odorizing spray. Today Ozone is considered by most to be the best available and advanced technology and a much better alternative than using chemicals.
Ozone Air purification is a continuous and safe process. There are two type of Ozone air purifier presently available, these are:
Duct mounted Ozone Generators : In this system Ozone cells are mounted inside the air duct and small amount of air passes through the Ozone unit. Out going Ozone rich gas from the Ozone unit is mixed with total air stream and does the purification job.
Ozone Injection into Air Duct : In this system Ozone is produced outside the duct and injected into the duct at a suitable location. In this system generation of Ozone, Control of concentration and quantity is independent of airflow, air quality, presence of moisture and any kind of contaminations or suspended impurities.
This system configuration can provide a much better control of Ozone mixing into air duct. Further this is a much more stable, reliable, maintenance friendly and does not need frequent cleaning and maintenance on the system. To conclude it is little more expensive and a long lasting system.
Ozone required to be dosed in a specific area e.g. a hotel room, restaurant, bar or a basement office depends upon the size (volume) of the room, position of air handling system, level & nature of Odour, temperature of the area, presence of moisture and dust.
Ozone quantity is correctly estimated by taking various parameters into consideration using a computer programme. However for a rough estimation, as a thumb rule, for an area of less odour and clean e.g. hotel rooms, offices, conference rooms, 1 gm/hr Ozone is required for 6,000 Cu.ft. space, while for area of higher bacterial contamination and foul smell as butchery, basement rooms, moist stinking areas, 1 gm/hr Ozone is need for 3,000 Cu.ft. space.
A very small Ozone concentration of 0.02 to 0.08 PPM is adequate for achieving air purification & deodorization, however on this concentration little more time is needed to get the desired results. Actual concentration required to be maintained at a place depends upon the presence of persons, type and nature of odour, the criticality of the area, duration required to purify and extent of foul smell. If no body is present in the room higher concentrations can be used for faster results.
Ozone Concentration should not exceed more than 0.1 PPM where persons are present, for eight hours or more per work day, and no person be exposed to a ceiling concentration of Ozone in excess of 0.6 mg/m³ (0.3 PPM by volume) for more than ten minutes. This limit is set as per OSHA standards.
Concentration of Ozone in air is monitored & controlled by Ozone Monitoring system manufactured by CREATIVE OZ-AIR (I) PVT. LTD.”. For Automatic regulation a feed back loop is used. The monitoring system is equipped with high & low level relay outputs, which are used for controlling Ozone concentration at the required level.
