When the temperature becomes conducive to microbial growth, they proliferate and emit a foul odor! An explanation of the smell of cutting oil and its causes.
Water-soluble cutting oils tend to increase in temperature as the weather warms from late May to mid-October, reaching a temperature range (20-40°C) that is conducive to the proliferation of microorganisms, which can lead to the release of unpleasant odors. These microorganisms include aerobic bacteria, which thrive in the presence of air (oxygen), and anaerobic bacteria, which reproduce in the absence of air (oxygen), both of which feed on the same organic materials to grow. Anaerobic bacteria reproduce more slowly than aerobic bacteria, but they produce a strong odor reminiscent of rotten eggs, which is the source of the unpleasant smell. Additionally, black mold, which prefers dark areas such as the bottom of tanks, can also develop at the boundary of the oil level in the tank. Since anaerobic bacteria reproduce slowly, it is often observed that when machines are left idle for extended periods during factory holidays or long breaks, these anaerobic bacteria proliferate and fill the factory with unpleasant odors. *For more details, please refer to the PDF document or feel free to contact us.*

Company information
Cool Tech is a manufacturer of devices and cutting oils that improve productivity in metal processing and enhance the environment. Since its founding in 1983, Cool Tech has contributed to improving the productivity of manufacturing lines, primarily in the construction machinery industry, through its engineering business. However, with the acceleration of overseas relocations of construction machinery manufacturers' production facilities, it became necessary to respond to these environmental changes. Based on the experience and knowledge gained from previous businesses, we have shifted our focus to the development, manufacturing, and sales of devices aimed at improving productivity for the metal processing industry. Currently, we offer a range of products that propose solutions to issues related to cutting oils, including water-soluble mist devices, high pH alkaline ion water generators, and accompanying specialized cutting oils, receiving support from numerous customers both domestically and internationally. Leveraging the experience and knowledge cultivated over many years in the engineering business, we will contribute to the development of the metal processing industry through product development that realizes productivity improvements in metal processing and sales through consulting for our customers.
