As industry changes its working practices to reduce costs and improve efficiencies to gain or maintain a competitive position within the market, some of the traditional methods of gas supply are being targeted. Domnick Hunter has developed its range of MAXIGAS and MIDIGAS nitrogen generators to provide intelligent on-site gas supply solutions to meet the demand of these dynamic market conditions.

The Domnick Hunter MAXIGAS/MIDIGAS system can be set to supply nitrogen with a residual oxygen content of between 10 p.p.m. and 3% dependent upon the application requirements. To meet the specific needs of differing customer demands the MAXIGAS range has two models, N2MAX and CAMAX. The N2MAX is designed to give a continuous stream of high to ultra high purity nitrogen while the CAMAX gives a pulsed flow of high purity nitrogen.

The key differences in the ranges are outlined below:

Features:

Compact modular design

• optimizes use of valuable production space
• allows unit to be upgraded as production expands

Economical

• one time capital purchase with short payback time
• once installed, minimal management costs associated with
  operation
• minimal servicing requirements

Reliable and Secure

• guaranteed nitrogen purity ensures consistent process results
• nitrogen available on demand 24 hours per day ensuring continuous, uninterrupted process operation

Other

• conforms to international standards
• performance tested prior to shipping
• low pressure operation
• transportable by forklift
• can be fed from existing air supply

• Laboratory - High Purity
  Gas Supply
• Food - Modified Atmosphere Packaging
• Electronics - Providing Protective Atmospheres
• Injection Moulding - Gas Assisted
• Fresh Produce Storage - Controlled Atmospheres

Also available, the NITROX range of ultra high purity on-site nitrogen gas generators has been designed to improve upon the traditional methods of supply within a laboratory environment by providing improved simplicity of operation and added cost effectiveness. The whole package is designed to meet and exceed the needs of each laboratory application.

The Domnick Hunter NITROX gas generation product range is the most extensive in the marketplace. With a range of purities from 2% to <10 p.p.m. O2 at flow rates up to 3000cc/min

The problem of storing hydrogen at high pressure and the associated health and safety risks are completely eliminated with the use of Domnick Hunter NITROX ultra high purity hydrogen generators which only supply gas on demand and at a low pressure.

You can now have a continuous uninterrupted gas supply which gives unprecedented GC baseline performance. you will not only improve the performance of you GC's, but also the consistency of carrier gas quality.

A wide range of product configurations allows all laboratory applications to be supplied and typically one unit can run as a gas carrier supply for 4-6 GC's or as a fuel gas supply for 12 FID.

The Domnick Hunter NITROX ultra high purity range of laboratory gas generators has been designed to exceed these current needs.

Simplicity of operation and one-off setup have eliminated the need for purging the system on every cylinder change making the traditional methods of supply a thing of the past.

Pure air is used a source of nitrogen or oxygen in analytical instruments where high purity or ultra high purity levels of these gases are not required.
The most commonly used applications utilize clean, particulate-free air which has had the methane removed from it, or is ultra dry air with the carbon dioxide extracted.

In certain applications both technologies are used to supply the required solution.

NITROX Zero Air generators provide up to 2500 cc/min of air with a methane content of <0.1 p.p.m.
NITROX Pure Air dryers generate up to 300 L/min of dry air with hydrocarbon levels of <0.01 p.p.m.
NITROX CO2 Removers provide up to 85 L/min of CO2 free air with purity levels of <0.003 p.p.m.
