We will introduce a case study on measures against "cosmetics and perfume odors" in a large warehouse. The warehouse used by a cosmetics company was filled with the unique fragrance odors of cosmetics. Attempting to remove the odors of fragrances that are designed to be difficult to break down artificially through ventilation would take over a year. Even using ozone, the stubborn odors take about 30 days to deodorize, but it is certainly possible to achieve deodorization in a short period. 【Case Study】 ■Location: Imizu City, Toyama Prefecture ■Work Area: 10,000 m³ ■Work Duration: 30 days ■Odor Level Before Measures: Odor Concentration 160 ■Odor Level After Measures: Odor Concentration 16 *For more details, please refer to the catalog or feel free to contact us.

Here is an example of measures taken to address "yeast odor" in a large warehouse. The yeast odor, which has a sweet and sour smell similar to sake lees, is derived from microorganisms. Therefore, even if the absorbed odor is deodorized, there is a risk of the odor recurring as long as the microorganisms remain. In this context, ozone, which also has strong sterilizing power, is used. It deodorizes the absorbed odor and kills the microorganisms, preventing the odor from reoccurring. 【Case Study】 ■ Location: Kobe City, Hyogo Prefecture ■ Work Area: 2500 m³ ■ Duration: 15 days ■ Odor Level Before Measures: Odor Concentration 130 ■ Odor Level After Measures: Odor Concentration Below 10 *For more details, please refer to the catalog or feel free to contact us.

We will introduce a case study on measures taken against the "rubber smell of tires" in a large warehouse. In a warehouse that stored 30,000 tires, a strong rubber odor had permeated the space. There were concerns that the rubber smell would adhere to the cardboard boxes of computers that were to be stored next. Therefore, ozone deodorization was implemented. When attempting to reduce the odor solely through ventilation, it would take over six months to achieve a reduction; however, deodorization was accomplished within 15 days, bringing the odor level down to a point where there was no odor adhering to the cardboard. 【Case Study】 ■ Location: Kure City, Hiroshima Prefecture ■ Work Area: 1500 m³ ■ Duration of Work: 10 days ■ Odor Level Before Measures: Odor Concentration 100 ■ Odor Level After Measures: Odor Concentration 16 *For more details, please refer to the catalog or feel free to contact us.
