When using liquid nitrogen (hereinafter referred to as LN2), it is mostly utilized under atmospheric pressure. However, since LN2 is at an extremely low temperature of -196°C under atmospheric pressure, it is stored and transported using vacuum insulated containers. When using LN2, it must be extracted from these pressure vessels. The "LN2 Liquid Extraction Device" introduced here allows for the extraction of LN2 with "high efficiency" and "low pressure." 【Features】 ● Enables high-efficiency liquid extraction ⇒ Reduction of losses ● Allows for quick liquid extraction ⇒ Improved work efficiency ● Enables low-pressure liquid extraction ⇒ Enhanced safety ● Simple operation (only valve opening and closing) ⇒ Standardization of work 【Examples of Use】 - Small-scale LN2 dispensing into Dewar containers, etc. - Freezing of food - Cooling of metals - LN2 applications in research facilities - Medical applications (dermatology, etc.) For more details, please contact us.

By preheating the ladle with a pure oxygen burner, we reduce preheating time and costs. The heat loss is minimal, and the preheating time is significantly shorter compared to conventional methods (oil burners). In particular, the conventional method made it impossible to install a cover (lid) on the ladle. By switching to a pure oxygen burner, it becomes possible to install a cover, which allows for improved thermal efficiency and higher preheating temperatures. Furthermore, compared to oil burners, there is a reduction in noise and an improvement in the working environment due to the elimination of oil smoke. 【Features】 - Shortened preheating time - Reduced preheating costs - High-temperature preheating capability - Improved workplace environment (noise & oil smoke) For more details, please contact us.

Traditionally, the use of oxygen combustion in aluminum melting furnaces has been considered difficult due to concerns such as the generation of aluminum dross. However, our original oxygen combustion program enables oxygen enrichment without increasing the generation of aluminum dross or the concentration of NOx in exhaust gases, contributing to improved productivity. Additionally, by using the specially developed "A Burner" (low NOx pure oxygen burner) for non-ferrous melting, it is also possible to transition to more efficient all-oxygen combustion. 【Oxygen Enrichment】 - Increased production speed The space in the furnace that was occupied by nitrogen gas is reduced, allowing for more fuel to be injected. - Reduced combustion losses The unnecessary heat loss due to nitrogen gas in the exhaust is decreased.

This is a high-speed jet burner suitable for melting inorganic materials, specifically designed for oil fuel. Typically, an oxygen enrichment of 2% (or an equivalent amount of oxygen using an oxygen burner or undershot oxygen lance) results in a production increase of 15-20% and a reduction in fuel consumption of about 15%. However, these values may vary depending on the application and usage. Additionally, if all fuel air is replaced with oxygen (that is, if an existing air combustion system is switched to a 100% oxygen burner), further improvements in production and fuel savings can be achieved.
