WHAT IS VOC?VOC is Volatile Organic Compound. Interior of modern buildings is infestedwith wide range of Organic and Hydrocarbon gases, released fromsynthetically produced interior furnishings such as carpets, curtains, ceilingtiles, paint, fabric protective coatings and cleaning aids. Occupantscontributed VOC include cigarette smoke, body odor, deodorant, food odor.Outdoor air intake to HVAC System may introduce automotive andindustrial effluents and odor, common in Downtown and Industriallocations. Continuous presence of VOC, even in low concentrations,adversely affect Indoor Air Quality, as occupants breathe them continuously.Many Indoor VOC are classified toxic, carcinogenic or carcinogen promoters.Some are odorous. Some irritate mucous embranes. VOC should be reducedsignificantly for safety, health and long term care of occupants.Ruks Engineered Ozone System eliminates or reduces VOC dramatically .

WHAT IS ODOR?Odor is detection and interpretation of a specific organic gas, by human olfactory senses. All odor is caused by chemicals. Someodorous gases are toxic and or carcinogenic, example benzene (gasoline), toluene, and methane. Not all odor are harmful, nor allharmful gases odorous. Yet, all odor are classified as VOC within the realm of IAQ. Odor may exist as transient odor – odor thatlasts just as long as the activity causing it lasts, or resident odor – odor causing chemicals retained in cellulose substances such ascarpets, ceiling tiles, and furniture fabric, and released at all times. No system eliminates resident odor except Engineered OzoneSystem. There are no known units to quantify odor, except human judgment.Ruks Engineered Ozone System eliminates or reduces Transient and Resident Odor.

WHAT IS CO2?CO2 is Carbon Dioxide. Common sources of CO2 in indoor space areexhalation by occupants, migration from outdoor air, and coal or woodburning heaters. CO2 is not a VOC, not a carcinogen, not a carcinogenpromoter, nor is it toxic. However, it is important to ensure CO2

concentration is not high. At elevated levels, CO2 causes reducedconcentration, fatigue, loss of productivity and lethargy. Permissiblelevel of CO2 for most applications is 1000 PPM by ASHRAE and OSHA.

WHY DO HVAC SYSTEMS PROMOTE GROWTH OF FUNGI?Conditions prevalent in air handling units and air ducts such as temperature, humidity,moisture on cooling coil and drain pan, and porous surface of duct lining are congenial forgrowth and propagation of mold and fungi. Through air vents, they enter indoor space. Fungicause allergies, breathing disorders, irritation and loss of concentration.Ruks Engineered Ozone System eliminates or reduces Mold & Fungi dramatically .

WHY DO HVAC SYSTEMS PROMOTEGROWTH OF AIR BORNE BACTERIA?Mold and Fungi are living organisms and form source of food andnutrients upon which air borne bacteria grow and propagate. Legionellabacteria is one example. Through air vents, they enter indoor space andexpose occupants to these. Elimination of mold and fungi in AC ducts andcooling coil eliminates or reduces air borne bacteria.Ruks Engineered Ozone System eliminates or reduces air borne bacteriain AC ducts and Cooling Coil.

QUALITY COMFORT AND ECONOMYFUNDAMENTALS OF INDOOR AIR QUALITY (IAQ)


WHY DOES DUST ACCUMULATE IN AC DUCTS?Force of adhesion is necessary for any particulate to adhere to any surface. In AC ducts, this is provided by bio adhesive forcecontributed by mold and fungi. If these are eliminated or reduced, dust particulates do not have the force to stick to duct surface.Ducts remain clean at all times.Ruks Engineered Ozone System keeps AC ducts and Cooling Coil free of dust and particulate Contaminant.

WHAT IS OZONE? Ozone is 3 atom molecule of oxygen with weak bonds. It is a powerful oxidizingagent. It is an unstable gas and reverts quickly to diatomic oxygen molecule or O2.When present with VOC, it oxidizes them. In the presence of ozone, VOC is subjectto continuous oxidation, transforming it into several transient gases. Resultantgases are totally harmless or less harmful. Total VOC is dramatically reduced. Odoris result of VOC. As VOC are removed, odor is almost completely eliminated. Netresult is indoor space with significantly reduced VOC, odor and smoke.

Fungi propagate by absorbing ambient oxygen, by process ofosmosis. Ozone, with oxygen, enters through outermembranes of cells of fungi. Ozone oxidizes the organicmatter in fungi. This retards cell multiplication andpropagation of fungi. Gradually, their colonies diminish. In thepresence of Ozone, fungi will not recultivate. Low residual

ozone concentration generated in Ruks Engineered OzoneSystem does not function as fungicide. It eliminates fungi bygradually decolonizing them. Elimination of mold and fungideprives food and nutrients for air borne bacteria to grow andpropagate in duct and coil. Without adequate supply of food,bacteria do not grow in ducts and coil.

OZONE AND FUNGI

WHAT ARE THE PRECAUTIONS?Ozone is beneficial in reducing VOC, Odor and depleting fungi. It is very important to ensure residual level of ozone does notexceed regulatory maximum permissible level.

WHAT ARE PERMISIBLE CONCENTRATION OF OZONE BY REGULATORY BODIES?OSHA & ACGIH (USA): 0.1 PPM (100 PPB)FDA: 0.05 PPM (50 PPB)WHO: 0.05 PPM (50 PPB)ASHRAE: 0.05 PPM (50 PPB)

CAN OZONE REDUCE CO2?Ozone cannot remove or reduce CO2, as CO2 is not oxidizable.Conventional method of limiting CO2 buildup in indoorenvironment is by diluting with outdoor air with low CO2

content.

• Ruks Ozone Generators produce ozone at low production density per unit surface area of the corona plates. This is essential in ensuring rate of production of ozone is in relation to rate of increase of VOC• Ruks Total Air Quality Monitor CZ8 – Automatic monitoring system with high quality Sensors for monitoring residual VOC, Ozone and CO2. VOC is oxidized by ozone, thus conserving available oxygen in fresh air to dilute CO2.

CO2 Sensor modulates outdoor air damper to alter outdoor air intake to limit CO2• Results in reduced demand for outdoor air yet improved IAQ• Reduction of outdoor air results in reduced HVAC Plant Capacity and hence reduced Capital Cost of the HVAC System• Reduced outdoor air also results in savings in Energy Cost

HOW DOES RUKS ENGINEERED SYSTEM IMPROVE IAQ AND YET REDUCE HVAC CAPITAL AND OPERATING COSTS?

*System operates in conformity to ASHRAE standards and regulations of OSHA, FDA, ACGIH and WHO


HOW TO ENSURE OZONE LEVEL IS BELOW PERMISSIBLE CONCENTRATION?• Use Ruks unique design Inline Duct Mounted, Low Production Density, Multi Plate Corona Ozone Generators• Operate corona on line frequency• Use automatic controllers to regulate ozone generation adequate to remove VOC• In occupied space, do not rely on manual controls, sense of smell or personal judgment• Use Fail Safe, Self Diagnosis with Fault Codes, Residual Ozone Monitor to ensure Ozone Generator is deactivated in the event Ozone Concentration exceeds Regulatory Permissible Levels - use Ruks Ozone Monitor CZ12• Where possible, interface control system to Building Management System

• Retain records and time history of levels of residual VOC and ozone• Do not use annular Corona tubes• Do not use portable ozone generators and generators without adequate controls• Do not use generators outside air stream that tube ozone into air ducts. Use generators in the air stream• Do not use corona that operates on higher than line frequency (60 or 50 Hz)• Use Ruks Total Air Quality Monitor CZ8 – Provides all of these features• Use Ruks Engineered Ozone System

WHY USE PLATE CORONA IN AIR STREAM, AND AVOID ANNULAR SPACE CORONA, FOR IAQ APPLICATIONS?

Assume a space where VOC is neutralized by ozone, where anarbitrary unit V represents the extent of VOC, and an arbitraryunit Oz represents ozone concentration. In a well balancedsystem, they both are very low. In this scenario, V and Oz arelow.

If pollution is now generated in this space, increase in VOC (δV)in relation to room volume is extremely low, in the order ofparts per million. Yet the adverse effect on IAQ of the space isvery high. To neutralize this small increase in VOC (δV), we needa small increase in ozone (δOz), and the generators shouldrespond to provide this as rapidly as δV changes. δOz/δT mustbe proportional to δV/δT. To achieve this, it is necessary to haveozone generator where production density of ozone (ozoneproduction per unit area of corona surface) is very low and

provide rapid response. That is, change of production of ozoneper unit time δOz/δT follows the same rate as δV/δT.

This is the key to achieving effective Indoor Air Quality, whereVOC is reduced to as low level as possible, and yet keep residualconcentration of ozone as low as possible. This is achieved onlyby the unique design of multi plate type of corona used in RuksOzone Generators, designed to produce minute density ofozone per unit area of corona surface, and yet have adequatecapacity to handle the load. Such system delineatesconcentration and quantity vectors, allowing concentrationvector to be held constant at low level, while allowing quantityvector to be altered, within reasonable limits. These aremounted inside the duct, thus providing the same media tosense VOC and Ozone.

V = Residual VOC, Oz = Residual Ozone, T = Time
