Supply options

Call Us or Email Us for advice on the most cost effective supply option to meet your needs, these include:

• Compressed nitrogen – gas cylinders for convenience or for mobile supply. Cylinder sizes and pressures are tailored to local markets.
• Liquid nitrogen cylinders – for small volume cryogenic applications.
• Bulk nitrogen – delivered by cryogenic tankers into on-site storage for high-volume applications.
• On-site nitrogen generation – for secure cost-effective supply, from low volume ultra-high purity nitrogen supply to electronics facilities to hundreds of tonnes a day for food freezing.

Processes

One of Nitrogen’s most useful properties is its chemical inertness to nearly all substances at ambient and moderate temperatures, making it a key gas in:

• Inerting, blanketing or padding – pure or in mixtures, as a protective atmosphere against oxidation or combustion by atmospheric air and contamination by moisture.
• Purging  – to displace or dilute unwanted gas or vapour, to reduce oxygen concentration or remove air, flammable or toxic vapour.
• Flushing – to flush unwanted gases from solutions, due to its only slight solubility in a wide range of liquids.
• Heat treatment  – as a protective furnace atmosphere for heat treatment of the most reactive metals.
• Food packaging – in mixture with carbon dioxide and oxygen in modified atmosphere packaging (MAP); pure to reduce oxygen concentration in respiring food products packaging.

Safety Information

• Nitrogen is not toxic and non-reactive except at high temperatures.
• If insufficient oxygen is present, high nitrogen concentrations cause asphyxiation and death. They are no physiological warning signs to nitrogen enrichment.
• Nitrogen does not support combustion.
• Liquid nitrogen has the capacity to inflict dangerous frost bites.
