From chicken wings to chicken curry, poultry has become a mainstay of global cuisine. Our Freshline® liquid nitrogen or carbon dioxide freezing and chilling systems are used in many poultry processing applications, including reducing bacteria in raw meat and individually freezing chicken nuggets so you can easily pull out of the bag the exact portion you want to make for dinner. 

Cinnamon (ground)

Our PolarFit® solutions use the cooling power of liquid nitrogen to remove heat produced during the grinding process of cinnamon and other spices. This temperature control not only enables the production of ultra-fine spice particles, but also helps preserve aroma and flavor.

Cleaner Air

We provide technologies that enable the capture, purification and reuse of carbon dioxide (CO2) and volatile organic compounds (VOCs). Building new plants with this technology or retrofitting the large installed base of existing coal-fired assets could significantly reduce CO2 and VOC emissions, resulting in cleaner air.

The fuel that uses the largest volume of our products is gasoline. Refiners use huge quantities of our hydrogen to reduce sulfur and other contaminants for cleaner-burning transportation fuels. 


Our oxygen helps melt glass in a way that saves energy, reduces emissions, and improves quality. Our nitrogen and hydrogen are used in the forming process to make flat glass for windows, furniture and cars. And our inert gases improve the insulating properties of windows.

Hard Drives

Helium is less dense than air and when used in computer hard drives, it creates less drag and turbulence, which improves speed and storage while using less power.


The heat produced from processing syngas--a mixture of carbon monoxide and hydrogen, which are two of our products--can be used to make electricity using a gas turbine or steam generator. Using syngas to produce heat or power is much cleaner than direct combustion of coal.

Hyperbaric Healing

It takes more than iodine and bandages to treat a wound these days. Sometimes it takes our medical oxygen, which is used in hyperbaric oxygen therapy (HBOT) for healing wounds and fighting infections. 

Ice Cream

Our Freshline® liquid nitrogen freezing systems help ice cream companies freeze all sorts of refreshing treats, like ice cream sandwiches. These systems also provide ease in shaping and forming novelty frozen treats. 


We play a role in keeping your homes and businesses more energy efficient by supplying fiberglass insulation manufacturers with our oxygen and burner technology, which helps them melt raw materials more efficiently and reduce their emissions.


High-speed internet uses fiber optic cables. In the manufacturing of these cables, our helium is used during the cooling process.

Jet Engines

Critical engine and landing gear parts are subject to various thermal spray processes that use oxygen, hydrogen, argon or helium to apply powder metal coatings. These coatings help protect the parts from thermal wear or corrosion, thus improving performance and reliability. In addition, our patented liquid nitrogen cooling technology is used to improve the efficiency of the spraying process. 


Whether you’re juicing, baking or incorporating your kale into a main dish or salad, you want it to be fresh. Some vegetables, like kale, begin to show signs of deterioration long before most other foods. When properly cleaned, chilled and placed in suitable packaging, the shelf life of some fresh produce can be significantly extended with our MAP (modified atmosphere packaging) gases.

Light Bulbs

Our products play many roles in the production of all types of lighting. Our oxygen and burner technology are used in melting the glass, and nitrogen is used to cool and seal the bulbs. In addition, argon and nitrogen help electrical energy pass through the filament in an incandescent bulb, while argon and krypton are commonly used in a fluorescent bulb. Argon also helps conduct the current in mercury vapor lamps that illuminate many of our streets at night.


High purity gases like our nitrogen meet the industry standards needed for pharmaceutical companies to safely manufacture critical medications. 


Liquid helium is the coldest substance on earth (-452°F) and is used to keep the electrical coils in MRIs (magnetic resonance imaging) cold, enabling the powerful images of your body that help doctors diagnose and treat diseases and injuries. 

Natural Gas

Our technology and giant heat exchangers have been used to produce most of the liquefied natural gas (LNG) made in the world over the past five decades.


Freezing, packaging and grinding with nitrogen or carbon dioxide can help provide the highest quality nutraceutical products for consumers focused on healthy living and wellness.
