The domnick hunter Industrial Division of Parker Hannifin has improved its existing range of MIDIGAS nitrogen gas generators, helping customers both improve productivity and reduce costs.

The launch of the enhanced MIDIGAS systems, which complement the proven MAXIGAS range, ensures that the company has the capability to offer nitrogen gas generators for low to high volume requirements.

As a result, customers can also now save costs further, improve productivity and in turn, increase profitability.

Nitrogen gas is used for many different applications throughout industry, with the MIDIGAS generators designed to offer a simple and cost effective method of producing high purity nitrogen in-situ - simply from a supply of compressed air. This therefore eliminates the need for traditional and expensive gas storage cylinders, dewars or bulk storage.

As a result, customers using MIDIGAS generators can make significant reductions in the cost of using nitrogen, with a fast payback on a MIDIGAS generator of between 12 and 24 months, and ongoing savings of up to 90% thereafter.

It’s thought that in addition, the onsite production of nitrogen will allow customers to overcome the environmental issues associated with road transport of bottled gas, as well as the unpredictability of fluctuating gas prices.

Each MIDIGAS generator is supplied as an integrated system, with a compact footprint and only requiring mains power and compressed air connections. The generators use proven pressure swing adsorption (PSA) technology, coupled with pairs of extruded aluminium modular columns filled with high performance carbon molecular sieves (CMS).

Such technology adsorbs 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.
