"Ecofreeze 774" is a product that balances excellent quality with essential elements needed as a refrigerant. The demand for natural refrigerants to replace fluorocarbon refrigerants has been increasing, and efforts to use carbon dioxide as a refrigerant have become more active. In response, our company has combined years of expertise in refrigerant supply with carbon dioxide quality management technology to successfully commercialize carbon dioxide (R744) that is more suitable as a refrigerant. [Features] - Balances excellent quality with essential elements needed as a refrigerant - Combines expertise in refrigerant supply with carbon dioxide quality management technology - Carbon dioxide suitable for use as a refrigerant *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the implementation of "EcoFreeze" for customers in the refrigeration industry. There were situations such as "the injection nozzles freeze" and "since the refrigerant for the refrigeration units introduced in the cold storage is carbon dioxide, we want to know the specifications and supply forms of the refrigerant gas used." After introducing EcoFreeze 744 (high-purity carbon dioxide), which is suitable as a refrigerant, we achieved results such as "we were able to carry out the installation without worrying about freezing" and "for large machines, we supplied using 30kg containers, and when transporting to rooftops, we adopted flexible 7kg and 5kg aluminum small containers, allowing for efficient filling operations." 【Overview】 ■Challenges - Injection nozzles freeze - Since the refrigerant for the refrigeration units introduced in the cold storage is carbon dioxide, we want to know the specifications and supply forms of the refrigerant gas used. ■Results - With a quality of less than 20 volppm moisture content compared to regular carbon dioxide, the risk of freezing is reduced. - For large machines, we supplied using 30kg containers, and when transporting to rooftops, we adopted flexible 7kg and 5kg aluminum small containers, allowing for efficient filling operations. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study of the implementation of "Eco Freeze" for customers in the showcase industry. "There is a consideration for developing showcases using natural refrigerants in line with the recent trend towards a fluorocarbon-free society," and "We want to fill equipment for R290 after-service" were the situations at hand. By introducing Eco Freeze 290 (propane), which is suitable as a refrigerant, we achieved results such as, "We were able to establish a stable gas supply through a supply method tailored to the filling amount," and "The introduction of a flexible 2kg container allowed for efficient filling of refrigerant gas during after-service on-site." 【Overview】 ■Challenges - Considering the development of showcases using natural refrigerants in line with the recent trend towards a fluorocarbon-free society. - Wanting to fill equipment for R290 after-service. ■Results - Established a stable gas supply through a supply method tailored to the filling amount. - The introduction of a flexible 2kg container enabled efficient filling of refrigerant gas during after-service on-site. *For more details, please refer to the PDF document or feel free to contact us.

The uses of carbon dioxide have greatly expanded, ranging from welding and beverages to steelmaking, chemical industrial materials, agriculture, and refrigerants. Off-gases generated from chemical and petroleum plants are collected, refined, and reused. The carbon dioxide and dry ice business creates new value while reducing environmental impact. Iwata Ni offers a comprehensive proposal from engineering gas supply equipment to supply and safety. *For more details, please refer to the PDF materials or feel free to contact us.

The "R290 Filling Device" is a gas filling device with a cylinder cabinet design that incorporates explosion-proof specifications for safety. It features a weight sensor to ensure high precision and fast response. Achieving a filling amount of 40 to 500g with a filling error of ±1g for high accuracy! It is easy to use with a touch panel operation. We also accommodate a variety of customizations tailored to your needs. We have a proven track record in a wide range of applications, from mass production to small batch production and research and development purposes.
