On-site storage for uninterrupted supply

If you’re looking for an alternative to cylinders, or require large amounts of industrial gas, our bulk and microbulk delivery systems can provide a reliable, uninterrupted supply of the gases and liquids to meet your business needs. Installed at your site, our bulk supply systems replace the need for high-pressure cylinders and eliminate handling and changeouts while meeting applicable federal, state and local safety requirements. Our bulk supply systems are available in a large variety of sizes and flow capacities to satisfy the needs of many applications.

Delivered by truck our products are transferred into a liquid storage supply system. These bulk systems provide product safely and cost-effectively. Alternatively, high-pressure gas tube trailers can be used for specialty applications as well. Let us help you experience fewer cylinder changeouts, provide lower operating costs, and reduced capital investment with our bulk and microbulk gas delivery supply systems.

MegaCal™ cylinder for industrial hygiene applications

Our MegaCal cylinders are designed to be an alternative to the disposable cylinders prevalent in the industrial hygiene market. These recyclable, high-capacity cylinders are ideal for high-volume applications yet are light weight and portable, matching the physical dimensions of the smaller cylinder they resemble. These easy to carry cylinders are plug and play capable with your gas detectors.

Pump up your process

Our fleet of mobile nitrogen pump trucks and tube trailers can deliver a continuous, dedicated supply of 99.9+% pure nitrogen for a wide range of industries and applications. And with the ability to supply nitrogen over a wide range of temperatures, we can deliver cold nitrogen for cooling hot catalytic reactor beds using our Nicool® Accelerated Reactor Cooldown Service and hot nitrogen for drying moisture-sensitive process units and catalysts. Our fleet can also respond rapidly to unexpected outages in refinery, petrochemical, fossil fuel, hydroelectric and nuclear generation facilities.

Our precisely controlled mobile pumping units can deliver nitrogen at the volumes you need at any combination of the following conditions:

Flow rates up to 660,000 scfh per pumper unit
Pressures up to 6,000 psi
Temperatures from -320° to 600°F
Experience the advantages of our mobile nitrogen service first hand.


Delivered fast and installed quickly, all equipment is set-up in one day (with product following shortly thereafter). In fact, all that’s required beforehand to make that happen is to have foundations and utilities in place.

A high value and very affordable solution, Praxair offers small on-site gas production in the form of “sale of gas” because Praxair builds, owns, and operates the plant at your site connected to your pipeline. You simply provide the utilities and pay for the products you use via a convenient and budget-friendly pricing plan.

Designed at our global technology center in Tonawanda, New York — where Dr. Carl von Linde invented air separation over 100 years ago — all Praxair air separation units are designed per local codes, customs, and our customer’s safety requirements.
