Liquid nitrogen at -196℃ allows for cooling to the desired concrete management temperature, ensuring uniform quality. Additionally, it is possible to keep initial investment low with simple equipment. By directly injecting liquid nitrogen into mixer trucks or batch plants, concrete can be rapidly cooled to the desired temperature. This enables smooth pouring even in summer and helps prevent cracking in the concrete. For more details, please contact us or download the catalog.

Our company is a gas and energy company. We would like to introduce industrial air separation gases "oxygen, nitrogen, and argon" that are separated from the air. 【1. Nitrogen Gas】 It makes up about 80% of the air and has the characteristics of being a liquid at -196°C and being an inert gas. It is widely used for purposes such as freezing food, preventing oxidation, and cooling metals. 【2. Oxygen Gas】 It has the property of supporting combustion and contributes to high-temperature combustion and the maintenance of life in organisms. Applications include steelmaking, which requires time reduction and environmental improvement, and aquaculture, which requires high-concentration oxygen water. 【3. Argon Gas】 It is an inert gas that makes up just under 1% of the air. Because it remains inert even at high temperatures, it is used as a filling gas in fluorescent lamps. In recent years, it has also been registered as a food additive, and it is becoming a gas of great interest, including its use as a filling gas for food.
