Nitrogen generators

Compact Midigas nitrogen generators are claimed to offer quick payback times and ongoing economies resulting from on-site gas generation from compressed air.

The three Midigas generators have been designed to offer a simple and cost-effective method of producing high purity nitrogen in situ, simply from a supply of compressed air. This eliminates the need for traditional gas storage cylinders, dewars or bulk storage.

By producing nitrogen on site, the Midigas generators allow users to overcome the environmental issues and carbon footprint associated with the road transport of bottled gas and the unpredictability of fluctuating gas prices.

The easy-to-use system is simple to install, requires minimal maintenance and eliminates safety hazards and OHS issues associated with traditional gas supplies. The compact design with modular option mean generators can be multi-banked if required. The generators stand 1034 mm high, 450 mm wide and 471, 640 and 809 mm deep, depending on the model.

Each Midigas generator is supplied as an integrated system and requires just mains power and compressed air connections. The generators use proven pressure swing adsorption technology, with pairs of extruded aluminium modular columns filled with high-performance carbon molecular sieves (CMS). These adsorb oxygen preferentially from the compressed air supply, with the larger nitrogen molecules being allowed to pass through each sieve to a storage vessel, from where the gas can be fed directly to process applications.

The operation of each Midigas system is fully automatic, making it easy to setup and operate, with the production of nitrogen being determined by the demands of downstream processes. This helps to reduce overall energy consumption and considerably extends the operating life of the unit, which is typically in excess of 10 years. Similarly, maintenance costs are low, with only routine maintenance required, while the modular design of the Midigas system enables the installation to be extended as and when nitrogen requirements increase.
