As we are also manufacturer of extractor hoods for commercial kitchens, we are inevitably faced with the expectation of kitchen owners and operators, that we should help them in the fight against the grease-contamination in the kitchen exhaust system. Decomposing grease, eliminating odors, killing pathogenic bacteria, without the use of chemicals, have given us the idea of developing UV air purifying technologies that can do this job. So in the last 4 years we have made a remarkable progress in the field of air purifying technology. Since our manufacturing facility is well suited to the production of air purifiers made from stainless steel, we only needed it to adapt to UV technology through improvements. We have recently adapted to our production a new purifying technology, the TiO2 photocatalytic air purification, which utilizes the synergy of UV light and photocatalyst. Here we are benefited significantly from the Hungarian scientific results of TiO2 research.
