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. Trying to remove the odors of fragrances that are artificially designed to be difficult to decompose 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 ■ Duration of Work: 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 introduction to measures taken against "yeast odor" in large warehouses. 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 recurring. 【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 Less than 10 *For more details, please refer to the catalog or feel free to contact us.

Here is a case study on measures taken against "mold odor" in a large warehouse. With the large-scale renovation of the warehouse, we carried out deodorization of various odors that had permeated over many years. Among them, we focused on the most strongly perceived mold odor, completing deodorization of 8 spans in 20 days. Mold odor is difficult to eliminate through ventilation, but it can be easily deodorized using ozone. 【Case Study】 ■Location: Daikoku Pier ■Work Area: 4000m3 × 8 spans ■Duration: 20 days ■Odor Level Before Measures: Odor Concentration 100 ■Odor Level After Measures: Odor Concentration Less than 10 *For more details, please refer to the catalog or feel free to contact us.

Here is an example of measures taken to address "tobacco odor" in a large warehouse. The area that was previously a smoking room was dismantled and converted into a warehouse. The interior was filled with a strong tobacco odor that had accumulated over many years. The tar that had adhered to surfaces was removed in advance, and after replacing the tile carpet and other materials, ozone deodorization was applied. The tobacco odor, which is said to be a mixture of hundreds of different odors, was easily broken down using ozone. 【Case Study】 ■ Location: Fuji City, Shizuoka Prefecture ■ Work Area: 750 m³ ■ Duration of Work: 5 days ■ Odor Level Before Measures: Odor Concentration 79 ■ Odor Level After Measures: Odor Concentration less than 10 *For more details, please refer to the catalog or feel free to contact us.

Here is a case study of measures taken against "organic solvent odors" in a large warehouse. The odor from the solvent used to draw white lines for partitioning within the warehouse was trapped inside. Due to concerns about the odor adhering to stored items, ozone deodorization was implemented. After 30 days, the odor was reduced to a level where it was no longer noticeable in all three spans. 【Case Study】 ■Location: Keihin Island, Ota Ward ■Work Area: 10,000 m³ × 3 spans ■Duration: 30 days ■Odor Level Before Measures: Average odor concentration 130 ■Odor Level After Measures: Odor concentration 16 *For more details, please refer to the catalog or feel free to contact us.

Here is a case study on measures taken against "fragrance odors" in a large warehouse. After removing air fresheners from a warehouse, pet food was stored there. The attachment of odors to pet food could lead to animals refusing to eat it, which is a critical issue for the product. Deodorization to a level close to odorless was required. Deodorization was successfully achieved to an odorless level within 30 days over 5 spans. 【Case Study】 ■ Location: Suminoe Ward, Osaka City ■ Work Area: 2200 m3 × 5 spans ■ Duration: 30 days ■ Odor Level Before Measures: Average odor concentration 160 ■ Odor Level After Measures: Odor concentration below 10 *For more details, please refer to the catalog or feel free to contact us.

Here is an example of measures taken to address the "rubber smell of tires" in a large warehouse. In a warehouse storing 30,000 tires, a strong rubber odor had permeated the space. There were concerns that the rubber smell would adhere to the cardboard boxes for computers that were to be stored next. Therefore, ozone deodorization was implemented. When attempting to reduce the odor through ventilation alone, it took over six months to achieve a significant reduction, but with deodorization, the odor was eliminated to a level where there was no smell on the cardboard within 15 days. 【Case Study】 ■ Location: Kure City, Hiroshima Prefecture ■ Work Area: 1500 m³ ■ Duration: 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.
