Industrial Uses
Blanket, Shield and Atmospheric Gas
Nitrogen atmospheres are a critical and predominant need in manufacturing. Pure nitrogen is commonly used in manufacturing as a "curtain" that displaces oxygen, which prevents combustion and keeps metals from oxidizing or rusting. This is also called shield gas. The greater Pittsburgh area and Western Pennsylvania are still poised as a geographic center and innovative leader in metals, the steel industry, powdered metals or sintered metals industry, heat treaters and OEMs using steel and stainless steel. These are all large consumers of nitrogen and other industrial shield and atmospheric gases. Greco Gas' microbulk and bulk gas solutions and delivery are an excellent choice for our larger customers.
Nitrogen for the Food & Beverage Industry
Nitrogen is essential in preserving foods, beverages and pharmaceuticals, again for its ability to prevent oxygen from doing its harm to organic matter. In food packaging, nitrogen flushes oxygen out of bags and containers to extend shelf life. In beverage production, it is used on its own and in mixed beer gas blends with carbon dioxide for draft systems, nitro coffee, and craft brews.

Cooling Applications
Nitrogen is used as a carrier gas for cooling applications or for removing other process chemicals and byproducts. Nitrogen turns to liquid at -320 degrees F and is similar in appearance to water. In this form, Liquid Nitrogen has many applications as a coolant.
Medical Use
The cooling and cryogenic effect of nitrogen in its liquid phase makes it a well-known solution as a medical gas. Greco supplies Nitrogen NF, which meets FDA purity and packaging requirements, to hospitals, medical clinics, laboratories, and universities. Common uses include preserving biological samples and supporting cryogenic procedures.
Chemical Processing
Used in manufacturing fertilizers; you may be familiar with the use of various derivatives of Nitrogen, including nitrates and nitrites, found naturally in organic fertilizer. Nitrogen gas is also used in making a myriad of medicines, even in antibiotics.
Grades of Nitrogen Offered
Greco Gas fills nitrogen in five grades, so you pay only for the purity your process needs. Industrial grade covers most blanketing, purging, and pressure testing work. Laboratory instruments and sensitive processes typically call for Prepurified, High Purity, or Ultra-High Purity, available through our high purity gas program. Medical NF is produced for healthcare use under FDA requirements.
- Ultra-High Purity (UHP)
- Prepurified
- High Purity (HP)
- Medical NF
- Industrial
Nitrogen Supply Options: Cylinders, Liquid, and Microbulk
How you receive nitrogen depends on how much you use and whether you need it as a gas or a liquid. Greco Gas supplies everything from a single nitrogen gas cylinder to thousands of cubic feet delivered to an on-site tank.
- High-pressure nitrogen gas cylinders: Suited to fabrication shops, labs, and lower-volume users.
- 12-pack cylinder clusters: For high-volume users who want fewer changeouts and less cylinder handling.
- Liquid nitrogen cylinders: Portable cryogenic containers for cooling and freezing work, or for operations that draw more gas than standard cylinders can efficiently supply.
- Microbulk and bulk nitrogen: An on-site tank filled by Greco delivery, built for continuous use. Learn more about microbulk installations and bulk nitrogen.

Nitrogen Supply FAQs
Greco Gas supplies nitrogen gas and liquid nitrogen from its fill plant in Tarentum and its stores in Butler and Kittanning, with delivery throughout the greater Pittsburgh area. Call (724) 226-3800 or request a quote online.
High-pressure cylinders hold nitrogen as a compressed gas and work well for lower or intermittent use. Liquid nitrogen cylinders hold nitrogen at about -320°F and store far more product per container, which makes them a better fit for cooling, freezing, or steady higher-volume use.
If you change out cylinders often or already run 12-pack clusters, a microbulk tank filled on site can reduce changeouts, cylinder handling, and unused gas returned in empty cylinders. Greco can review your usage and recommend the right setup.
Industrial grade handles most blanketing, purging, and pressure testing. Analytical instruments and sensitive lab work usually require Prepurified, High Purity, or Ultra-High Purity nitrogen, and healthcare applications require Medical NF. Our team can help match the grade to your application.
Yes. Greco Gas makes scheduled deliveries of nitrogen cylinders, liquid cylinders, and microbulk fills to businesses throughout Pittsburgh and Western Pennsylvania from our Tarentum, Butler, and Kittanning locations.
Nitrogen is nonflammable and nontoxic, but it is an asphyxiant and can displace oxygen in enclosed or poorly ventilated spaces. Store cylinders upright, secured, and in a ventilated area, and wear cryogenic gloves and eye protection when handling liquid nitrogen. Safety Data Sheets are available on our SDS page.
