Iwatani responds to customer needs with a rich lineup, from small devices to super-large plants. We also propose an optimal total supply system for nitrogen gas, including a backup system unique to gas manufacturers. We offer a wide range of options focusing on initial costs, running costs, and energy-saving features (optional), so please feel free to let us know your requirements. *We also accommodate requests for low-purity nitrogen below 99%. We will make proposals tailored to your needs.

The "Nitrogen Gas Generation Device KURASEP for LASER" is a product that can generate high-pressure, high-purity nitrogen for laser processing in an energy-efficient and cost-effective manner. We offer two types: the "Hydrogen Gas Usage Type," which pursues cost reduction and space-saving, and the "Hydrogen Gas Non-Usage Type," which eliminates the need for managing hydrogen cylinders and is hassle-free. 【Features】 ■ Increased separation efficiency of nitrogen and oxygen due to the adoption of a new adsorbent ■ Implementation of further energy savings with a new system (patent pending) ■ Capable of supplying high-pressure, high-purity nitrogen gas according to processing conditions ■ The system includes boosters, purification devices, and more *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

The "N2-PSA" is a portable nitrogen gas generation device (PSA) that can self-generate up to 500 Nm3/h of nitrogen gas (at 99% nitrogen purity) per unit. It can be transported by a 10-ton truck and is suitable for outdoor installation. By switching from normal four-tank operation to a reduced supply two-tank operation, it allows for operation while suppressing compressor power and performing maintenance. Additionally, it can accommodate high-purity nitrogen gas supply by adjusting the gas flow rate. 【Features】 ■ Capable of generating nitrogen gas even when supply by tanker is not possible ■ Outdoor specification and portable, suitable for a wide range of installation locations ■ Cost-effective rental option available for use only when needed ■ Exempt from high-pressure gas safety regulations ■ Low noise operation with a silencer *For more details, please refer to the PDF document or feel free to contact us.

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.

The ultra-compact N2-PSA "Micro-mini" series is a nitrogen gas generation device with a built-in oil-free compressor that can generate nitrogen gas at a rate of 4 NL/min (at 99% purity). *It can accommodate concentrations up to 99.99%. Many customers use it for research and development purposes aimed at research institutions, and we can suggest appropriate models based on customer requests. Please feel free to consult us when considering your options. <Features> ■ Rental options available ■ Long lifespan and low noise ■ Same-day repairs possible for maintenance or sudden issues (via courier) ■ Simple operation method ■ Stable nitrogen supply possible even in locations where supplying nitrogen with cylinders is difficult (no available space, on the second floor, etc.)
