1 CLIMATIC A DVANCED POLLUTION CONTROL REMOVAL OF PARTICLES AND GASEOUS POLLUTANTS IN A SINGLE TREATMENT The new CLIMATIC solution for healthier indoor air

2 INFUSER VENTILATION CLIMATIC The air pollution control system that effectively removes 98% of particulate matter (PM) and up to 83% of gas-phase pollution in a single treatment cycle Increased levels of outdoor air pollution can lead to decreased air quality inside buildings, resulting in adverse health effects and discomfort to occupants. The CLIMATIC air pollution control system offers a new and flexible way of removing the ambient air pollution before it enters a building s ventilation system, ensuring clean and breathable indoor air. The CLIMATIC offers a new state of the art air pollution control system, capturing pollutants in a highly effective single treatment cycle before they enter the central heating, ventilation and air conditioning system (HVAC) of a building. The CLIMATIC creates a semi-closed environment with clean air inside buildings shielded from the polluted air outside. The CLIMATIC is modular and easy to install as clamp on to any existing HVAC system. The system requires no or little additional modifications or changes to existent HVAC systems. The CLIMATIC from INFUSER is scalable according to air volumes and pollution. The system is easily installed in line with air intake piping or ducts, e.g. on the roof of a building, or it can be integrated into more complex piping structures as part of a building s central HVAC or duct system. The CLIMATIC system is available with an intelligent monitoring system - SMART-AIR offering air purification on demand.

3 Key advantages: Removes in a single treatment cycle 98% of PM and 50-83% of gaseous pollutants, such as NOx and SO2 Builds up no waste or hazardous by-products Increases the life of existent ventilation filters by removing particles from incoming air Easy to integrate and install into existent HVAC systems Comes with optional intelligent SMART-AIR system Modular and scalable design Low or no pressure drop, benefiting the overall energy consumption Easy and flexible to service and maintain

4 INFUSER VENTILATION REFERENCE PROJECT The Royal Danish Embassy Beijing, People s Republic of China As a world s first, INFUSER installed its CLIMATIC pollution control system on the roof of the visa building of the Royal Danish Embassy in Beijing in January Designed as an air purification solution requiring no structural reinforcements to the roof, the CLIMATIC integrates fully with the building s existing air intake. Today, the CLIMATIC provides clean and breathable air to the staff and visitors to the building. The Royal Danish Embassy quickly saw the benefits of having INFUSER s CLIMATIC system at the visa building. Not only does the CLIMATIC offer a very effective solution to the long lasting problem of inferior indoor air quality, the system also offers the embassy a direct cost saving. By removing the particles from the inlet air stream without the use of conventional filters, the lifetime of the existing ventilation filters has been extended. Frequent filter changes are now a thing of the past! Problem: Indoor air quality at the embassy (visa building) Present air treatment system: Conventional filter technology Air flow rate: 600 m3/h Temperature outside air: Ranging from -20 C (winter) to +40 C (summer) Having been deeply involved in the testing of the performance of the CLIMATIC at the Royal Danish Embassy in Beijing, I am nicely surprised to see the system s high removal efficiency. The greater number of such individual installations, the better the chance for solving our air pollution problems. I can see the big potential of the CLIMATIC in China.

5 AQI (EPA method) Before CLIMATIC treatment After CLIMATIC treatment Figure 1 Air Quality Index (AQI) values before and after the CLIMATIC air purification unit on a typical day on the roof of the Royal Danish Embassy in Beijing with an average pollution load. Shown are AQI values for Particulate Matter smaller than 10 µm (PM10) and 2.5 µm (PM2.5) respectively, Nitrogen Oxides (NOX), Sulfur Dioxide (SO2), and Ozone (O3). PM 10 PM 2.5 NO X SO 2 O 3 To test the on-site performance of the CLIMATIC system installed on the roof at the Royal Danish Embassy in Beijing, a field campaign was conducted over 10 days in March During this period a number of gas- and condensed-phase parameters were monitored before and after the installation to monitor air cleaning performance. AQI for all measured parameters are strongly reduced by the CLIMATIC unit, with condensed- and gas-phase removal efficiencies of 97-98% and 48-83% respectively, cf. Table 1 below. All measured parameters were delivered to the air intake system of the embassy at levels that are classified as good on the United States Environmental Protection Agency (US-EPA) AQI scale.

6 INFUSER VENTILATION TECHNOLOGY The CLIMATIC harnesses nature s self-cleaning properties to purify air The atmosphere plays a vital role in protecting and sustaining life of Earth. The CLIMATIC uses Gas Phase Advanced Oxidation and Electrostatic Precipitation to remove pollution from an air stream. The air cleaning is achieved by combining and accelerating the selfcleansing properties of the Earth s atmosphere in a closed system the CLIMATIC. Air is led through the CLIMATIC for purification before entering the building as clean and breathable air. The gaseous oxidation process in the CLIMATIC transforms ozone, a highly effective oxidant, into OH radicals by irradiation with high intensity UV light. OH radicals are extremely reactive towards gas-phase pollutants, transforming them into particles, which are removed together with other particulate matter by an electrostatic precipitator. Any residual ozone (O3) from the process is catalytically converted to harmless oxygen (O2) in a final treatment stage, leaving only clean, particle free air. The CLIMATIC s Gas Phase Advanced Oxidation occurs without obstruction to the airflow and pressure drop across the electrostatic precipitators is minimal. The CLIMATIC construction is a modular design allowing for flexibility, scalability, and cost optimization. The CLIMATIC can be up- or downscaled in size according to air volumes and pollution loads.

7 SMART-AIR The intelligent monitoring system offering air purification on demand Pollution load in cities and urban centres peak at different times of the day, often varying with the seasons. SMART-AIR is an intelligent automation add-on to the CLIMATIC that monitors the air pollution and thereby the need for cleaning by the CLIMATIC. The CLIMAT- IC can create a semi-closed environment with clean air inside buildings, shielding them from the polluted ambient air. In other words, SMART-AIR offers cleaning on demand. The SMART-AIR system is equipped with sensors to keep track of the ambient air pollution load. The system offers several benefits: The cleaning pattern of the CLIMATIC can be set up to mirror the specific location s pollution characteristics If the CLIMATIC senses that pollution levels are low, it can turn down cleaning power until levels increase again. This saves energy and prolongs the lifetime of consumables within the CLIMATIC The CO2 levels in a building are determined by occupancy and activity. Ambient air is only supplied to the ventilation system, and thus the CLIMATIC, when CO2 thresholds are exceeded, further saving energy.
