Nitrogen
Nitrogen for cooling, chilling, freezing and packaging
Nitrogen is essential to life on Earth
Nitrogen compounds are present in organic materials, foods, fertilisers, explosives and poisons. Nitrogen is essential to life on Earth and can be found in all living systems.
Nitrogen in food and beverage
Nitrogen is a key cryogenic agent in food and beverage cooling, chilling and freezing. Liquid nitrogen offers the quickest freezing method and also plays a key role in minimising spoilage, discoloration and off–flavours.
At BUSE, we can help you freeze in the freshness with our extensive line of food fresh certified cryogenic systems. BUSE has a full line of cryogenic applications designed to deal with a variety of foods, from meat and seafood to baked goods and produce.
Our liquid nitrogen slows bacterial growth and assures uniformity of temperature, which is essential to obtaining accurate and repeatable results with products. Properly chilled meat and pork also ensures the perfect incorporation of fats without smearing and maintain the unique properties of blended flavourings and spices.
Nitrogen in aerospace and aircraft
Essential to the aerospace and aircraft industry, nitrogen is used in heat treating furnaces and autoclaves to help create incredibly strong but lightweight materials. Nitrogen is also used as an assist gas for laser cutting applications and aviation approved aircraft tyres.
Nitrogen in automotive and transport
Assembly plants use nitrogen in combination with other welding gases to weld auto parts, frames, mufflers and other components because of its ability to provide the necessary atmosphere needed to produce adequate welds with any material.
It’s also an important safety component within airbags, climate control systems, electronics, lighting and tyres.
Nitrogen in chemicals and petrochemicals
Used as a pressurising gas, nitrogen can help propel liquids through pipelines. It is also used to shield oxygen-sensitive materials from the air and to remove volatile organic chemicals from process streams.
BUSE nitrogen helps chemical manufacturers produce moulded parts and plastic films with significantly higher surface quality and reduced scrap rates.
And our expertise in gas and liquid supply makes us uniquely qualified to custom tailor a system to match your precise purity requirements, fluid viscosity, operating conditions and process equipment.
Nitrogen in energy
As an inert industrial gas, nitrogen is used as a blanketing agent to separate sensitive products and processes from air. It is also used as a purging agent in piping and equipment to prevent contamination.
Nitrogen in healthcare
Nitrogen NF is used as a cryogen to freeze and preserve blood, tissue, and other biological specimens, and to freeze and destroy diseased tissue in cryosurgery and dermatology. It is also used to power medical devices.
BUSE can equip your lab with a full line of medical, specialty and laboratory gases and gas mixtures customised to your requirements for everything from growth culture for microorganisms to calibrating and operating analytical instruments.
And in cryotherapy, where an extremely cold liquid or instrument freezes and destroys abnormal cells, BUSE can work with you to provide a cost-effective, reliable supply of the gases.
Nitrogen in laboratories
One of the largest uses of nitrogen gas in the laboratory sector is sample preparation ahead of Chromatography or Mass Spectrometry (LCMS or GCMS) where a nitrogen blowdown evaporator is used to concentrate liquid samples before analysis. This requires access to a steady, and sometimes high-purity, nitrogen source.
Nitrogen in refining
An industrial gas used to blanket storage tanks and purge pipelines, nitrogen can also strip Volatile Organic Compounds (VOCs) from chemical process streams and wastewater and reduce VOC emissions.
Nitrogen is also used in the electronics space to reduce the risk of oxidation and allow proper wetting of the solder and the devices it is used on and glassmaking where nitrogen is used to inert the glass. It is also used in nitrox blends for short surface and longer bottom diving.
Nitrogen in Laser Cutting Applications
Nitrogen primarily used as an assist gas to enhance the cutting process for metals like stainless steel and aluminium.
By providing an oxygen-free environment, nitrogen helps prevent oxidation along the cut edges, resulting in cleaner, more precise cuts with minimal discolouration.
This inert atmosphere not only improves the quality of the cuts but also increases the processing speed and overall efficiency of the laser cutting operation.
