Air cleaning as a service

Technology

UVR (Ultra Violet Radiation)

UVR module

The UVR module is the primary treatment module for industrial implementation of the CLIMATIC technology. The technology is based on accelerating the self-cleansing mechanisms of the atmosphere, namely a carefully adjusted combination of gaseous oxidants, water vapor and UV light. This produces OH radical molecules (Reaction 1) which are extremely reactive towards most volatile organic compounds (VOCs) (Reaction 2). O3 + UV light   →       OH           (Reaction 1) VOC + OH      →      OxVOC                     (Reaction 2) The VOC are thereby first oxidized to OxVOCs, but thereafter precipitate out of the gas phase as particles (Reaction 3). The particles can thereafter be removed by a particle filter. Finally, the air is freed of excess ozone by an active carbon filter. For increased lifetime of the active carbon filter, an automated washing cycle is installed. OxVOC         →      Particle                     (Reaction 3)

WAC (Wet Adsorption Catalyst)

After passing through the UVR module, the original VOCs have been reacted away. However, the air will still contain substantial amounts of ozone, which has been created by the UV light, oxidized VOCs (OxVOC) from reaction 2 and particles from reaction 3, which must be removed before the air can be exhausted. Since both particles and OxVOCs are known to be very water soluble, these can be removed over a wet surface. Ozone is not very water soluble, but is readily removed by a variety of different catalysts, such as metal oxides, ceramic materials or even activated carbon. In order to minimize the complexity of any given installation, the removal of these three by-products are conducted in a single treatment over a wet adsorption catalyst.

GEC (Gas Enhanced Catalyst)

Industrial production facility most often involves several different facilities, each performing one or more specialized processes. Most often, each of these facilities have different requirements with respect to ventilation and produce different amounts and kinds of pollution. Specially designed for tackling high concentration of pollutants at the point source, our GEC has been developed. The GEC contains a noble metal catalyst deisned for roubustness and longevity, and is operated at temperatures between 300 and 400 oC.

ESP (Electrostatic Precipitator)

One of the primary methods which VOCs and other pollutants are removed in the natural atmosphere is via gas to particle conversion. The same processes are used in the UVR section, leading to the conversion of millions of separated gaseous molecules into a single particle. The advantage of this process is that it is much easier to remove a single particle, rather than a million molecules. Several conventional processes can be used, but due to longevity and ease of operation, we have developed a self-cleaning ESP enabling continuous operation for extended periods of time.

The Hydroxyl Radical

– the DNA of the CLIMATIC technology

The hydroxyl radical is the most important oxidant in the atmosphere, and it is responsible for breaking down and oxidizing gaseous pollution.

After reaction with a VOC (volatile organic compound) the reaction products are chemically and physically transformed such that they are much less volatile and much more water soluble.

The CLIMATIC UVR-WAC system is designed to take advantage of these changes of properties, such that after the oxidation by the OH radical in the UVR module, the by-products are captured and washed away in the WAC module.
