Draining - The turbulence caused by the drain, has the potential to interfere a lot of air with the liquid to be bottled, which increases the risk of oxidation. The nitrogen acts to displace the oxygen and maintaining the liquid under the drain


Beer frothing - When beer foamed using nitrogen produced the hordein-derived polypeptides that provide the most stable foam which gives the beer a mouth feel and 'creamy' texture.


Drink Storage - use of nitrogen has been very commonly associated with to prevent product oxidation and any enzyme or microbiological related reaction. Nitrogen is a gas which is inert, odorless, it does not dissolve, it is not toxic, and it reduces the use of additives


Bright annealing - For maximum brightness during annealing, this application requires the addition of nitrogen in the oven. The higher the temperature in the oven, the higher the purity nitrogenens be.


Carbon Fiber Curing - Small hardening facilities for materials such as metal, carbon fiber, Kevlar and other high strength fibers will be on-site nitrogen generators be the ideal solution.


Chemical plants - Nitrogen is used for inert filling the headspace of chemical storage or process tanks. Creating an oxygen-poor environment reduces risks and prevents explosive environments.

Curing - facilities for the curing of materials such as metal, carbon fiber, Kevlar and other high strength fibers can draw many benefits from on-site nitrogen generation.


Aircraft tires Inflation-Nitrogen is not flammable and dry. This combination has led to calls that all passenger aircraft tires regularly subject to severe operating conditions, must be filled with nitrogen to remove condensation / freezing at high altitude and to avoid accidents.


Enhanced Oil Recovery - On pressurization of the oil well, an ideal gas is nitrogen. It increases productivity and has no corrosive effect on the bore tube (as opposed to carbon dioxide).


Ethanol production / bio-fuels - Nitrogen is used to remove moisture while pressurizing, blanketing and inerting and storage and holding tanks.


Explosive atmospheres - Checking gas / steam compared. Explosion hazards is often a necessity for chemical process safety. The safest way to prevent explosions is to displace oxygen with inert nitrogen.


Fire extinguishers - Powder extinguishers come in a variety of types and are suitable for a combination of Class A, B and C fires. These are filled with foam or powder, and pressurized with nitrogen.


Fire Prevention / suppression - Nitrogen is an excellent fire prevention and fire suppression tool as it is able to reduce the oxygen concentration in the most efficient manner on site.



Food industry - Nitrogen is an efficient and cost-effective manner, without the use of additives to stop bacterial growth, reduce oxidation, preserving the taste and consistency, extend product shelf life and improve the visual appeal of freshness.


Explosion Protection of Fuel - To replace the potentially explosive vapors in the fuel tanks, nitrogen can be used.


Gassed injection molding - The principle of this method is that the nitrogen gas is injected during molding, either directly or through the inlet into the mold tool. In a controlled high pressure This has the advantage to overcome sink marks or introduce a cavity without the need for any core.


Prevention of explosions in grain silos - Grain dust in the oxygen-rich grain silos and grain elevators are very dangerous. Nitrogen is used to inert, eliminating the danger of an explosion.


Health & Beauty - oxygenation of the air will hurt commodities and different ingredients. Using nitrogen as inert, the risk of oxidation completely removed.


Heat treatment - heat treatment is controlled heating and cooling of metals to change their physical and mechanical properties without changing the shape of the product. In order to avoid any undesired oxidation during this process is subject oven and covered with nitrogen.


Jewellery manufacturing - If gold furnaces contains oxygen, the risk to discolor or weaken the product great. Therefore, the air in the furnace is advantageously displaced with nitrogen.


Kiln / grain drying - The extremely low dew point of nitrogen makes it an ideal choice for drying grain and oven, also very effective to inhibit microbial growth.


Laser Cutting - The advantages of nitrogen cutting is known for processing SS and aluminum. Today, with the new super-fast motion systems with rapid acceleration and deceleration, it is necessary to use nitrogen as cutting gas, even in mild steel to get the maximum efficiency from the laser cutting machine.


Laser welding - Nitrogen is used around the laser head to maintain the correct welding temperature and force oxygen and moisture out of the beam path, thus avoiding oxidation.


Unleaded soldering - The use of nitrogen expands the temperature window for the soldering process itself, while providing more flexibility for the solder paste. In this way, the same temperature profile is used for various types of solder or solder paste.


Leak test - Nitrogen is used to detect leaks in various plumbing or piping applications. The gas is injected under pressure to control connections in brazing, welding and threaded fittings.


Milk powder packaging - packaging of milk powder with the MAP system, increases its durability and prevents the product becomes rancid.


Mining trucks tires Inflation - Compressed air containing oxygen and water vapor, therefore, causing tires higher temperatures, pressure variation, and corrosion of the deck. This results in increased wear of the tires. Due to the absence of moisture, the nitrogen inflated tires not oxidizing and run cooler, leading to reduced corrosion and extended life.


Modified atmosphere packaging - Nitrogen is an efficient and cost-effective manner, without the use of additives can stop bacterial growth, reduce oxidation, preserving the taste and consistency, extend product shelf life and improve the visual appeal of freshness.


Off shore platforms - In the off shore applications, air can be replaced with inert nitrogen to displace the oxygen to retard oxidation and inhibit any explosion or fire.


Oil extraction - Nitrogen is used to repressurize depleted oil wells. Inert nitrogen has a corrosive effect on the bore tube while it has advantages compared. Increased productivity.


Pharmaceutical products - the most common pharmaceutical applications are covering, inerting and sparging, to prevent oxidation and / or reduce flammability.


Bacteria elimination - The use of nitrogen instead of air which contains oxygen, creating a so-called hypoxia, which prevents bacteria to survive. This prevents the organic forms of contamination with unwanted bacteria and prevent mold or mildew formation.


Drying of the pipeline - the extremely low dewpoint nitrogen makes it an ideal choice for drying of the pipelines. As an added value feature, nitrogen completely inert thus delaying oxidation and prevent explosions.


The pipeline Inerting - Nitrogen is the preferred gas to displace oxygen retard oxidation, breaking a "burning triangle" and prevent explosions.


The pipeline Pigging - Use of nitrogen as an inert propellant to move the "pigs" through the pipeline during the execution of major maintenance or remedial treatments are the ideal solution.


Printing - High speed printers require nitrogen for drying and to prevent oxygen contamination during film production and separation.


Refineries - Nitrogen is used to inert storage or process tanks and move product through pipelines to refineries. Nitrogen prevents hazardous or explosive environments.


Semiconductors - nitrogen of high purity used for inertion the component level manufacturers and semiconductor manufacturers.


Sintering - to form a coherent bonded mass by heating the metal powders, without melting the sintering process can be used. Oxygen which oxidises the metal, is replaced by nitrogen so as to produce an inert atmosphere during the sintering process.


Autoclave - in a composite treatment, a dry air autoclave under pressure with nitrogen gas and then internally heated. Specialized materials will bond or "cure" in an autoclave. The process is intended to produce specific properties in the coating raw materials such as light weight with great strength or specific type of stiffness. Materials with high strength and low weight is beneficial for many industries such as aerospace, automotive, and many others.


SMT (Surface Mount Technologies) - Adding nitrogen to a SMT line provides benefits such as higher quality by eliminating the causes of cavities, with an economic cost and continuous operation.


Underbalanced drilling - Nitrogen is used as the circulating liquid medium to underbalanced drilling rigs to drill oil and gas wells, wherein the pressure of the wellbore is kept lower than the fluid pressure.
