Get safe and reliable gas supply for inerting and blanketing from Airgas, an Air Liquide company
Improve quality and safety
Your process and end-product quality can be directly impacted by contaminants and moisture. Inerting and blanketing help prevent the oxidation or contamination of substances by forming a protective layer of gas, by entirely or partially replacing the air around your product with gas to prevent moisture or oxygen from coming in contact with a reactive or flammable substance. Inerting with high-purity gas helps you maintain process and product quality, and improve safety and compliance with regulatory requirements.
What are your challenges?
How can industrial gas help?
Gas is most commonly used to form a protective layer, replacing air around or on top of the substance to keep moisture, oxygen or microbial growth or pests from coming in contact with a flammable or reactive substance.
- Protect product quality as well as your equipment from oxidation and moisture impact
- Provide an efficient and safe purging method for vessel offloading
- Improve compliance and meet technical and safety standards like NFPA, PAI, FSMA, NEMA and more
- Evaluate your system and site conditions with the help of Airgas experts to help minimize gas consumption rates and maximize savings
- Track daily consumption with a remote monitoring service to help forecast spikes and optimize costs
Preventive inerting is the continuous maintenance and protection of an inert atmosphere within an area. This is generally implemented for installations where there is a permanent risk of explosion. Corrective inerting consists of injecting inert gas when an explosion risk is detected.
- Improve plant safety and reduce risks associated with flammable liquids
- Meet safety standards and comply with specific industry regulations like NFPA, PAI, FSMA, NEMA and more
Get the right gas for your process
Selecting the right gas quality is the first step to improving your process. The quality of inerting and blanketing is directly attributed to the gas used. Airgas offers customized gas solutions using high-purity gases including argon, carbon dioxide and nitrogen that are free of oxygen, moisture and other contaminants. Our gas experts can help you define the best pure gas or gas mixture for your process, in the right quantity, plus equipment for any type of process including purging, blanketing, vessel pressure transfer, and more for most plant operations.
Keeping gas supply without runout is critical to your process. Airgas offers a variety of supply modes that are flexible and can grow with you. With one of the largest distribution footprints in the US, we can ensure reliable and quality gas supply, delivered when and where you need it.
