How important is the supply of nitrogen to your business? For many companies, a reliable supply of nitrogen gas is essential. domnick hunter understands the key role nitrogen can play and the fundamental need for a reliable and secure supply. For over 40 years domnick hunter has been a world leader in filtration, purification and separation technologies in a diverse range of industries, domnick hunter is universally known for developing high quality products, technical innovation and partnerships with customers.
You can now generate your own nitrogen gas at the press of a button – as much or as
little as you need, at a fraction of the cost of your existing supply and at the purity your
process requires. The generators are virtually maintenance free. Simply switch on and let
your domnick hunter nitrogen generator do the rest.
Every time you order gas cylinders or liquid nitrogen, you not only pay for the gas itself, but also for:
- Internal Order Processing
Now these and many other problems associated with nitrogen gas supplies can be eliminated in a manner that is not only more efficient, reliable and safe, but also at lower cost.
BENEFITS
Convenient, secure supply
With MAXIGAS, the nitrogen you need is always available on demand, 24 hours a day, eliminating the risk of lost production time due to gas running out.
The right purity
MAXIGAS systems deliver the nitrogen purity your application needs - from 5% to 10ppm oxygen content as standard.
Space saver
The compact design of MAXIGAS means that installations take up less floor space than other
systems, and will fit through a standard doorway.
No growing pains
domnick hunter’s unique modular design simply means that extra banks of MAXIGAS can be added as your business grows and gas requirements increase.
The safest supply
Eliminate safety hazards of storing, handling and changing heavy, high pressure cylinders.
Cost savings
Producing nitrogen from compressed air with MAXIGAS can cut your operating costs significantly. No on-going cylinder costs; i.e. rental, re-fill, delivery, order processing.

Pressure drop is a term used to characterize the reduction in air pressure from the compressor discharge to the actual point-of-use. Pressure drop occurs as the compressed air travels through the treatment and distribution system. A properly designed system should have a pressure loss of much less than 10 percent of the compressor’s discharge pressure, measured from the receiver tank output to the point-of-use. Flow restrictions of any type in a system require higher operating pressures than are needed, resulting in higher energy consumption. The most typical problem areas include the aftercooler, lubricant separators, and check valves. A rule of thumb for systems in the
100 psig range is: for every 2 psi increase in discharge pressure, energy
consumption will increase by approximately 1 percent at full output
flow. There is also another penalty for higher-than-needed pressure.
Raising the compressor discharge pressure increases the demand
of every unregulated usage, including leaks, open blowing, etc. For
systems in the 100 psig range with 30 to 50 percent unregulated
usage, a 2 psi increase in header pressure will increase energy
consumption by about another 1.0 percent because of the additional
unregulated air being consumed. The combined effect results in a total
increase in energy consumption of about 1.6 to 2 percent for every 2 psi increase in discharge pressure.The control range pressure setting must be reduced to allow for actual and potentially increasing pressure drop across the dryers and filters. Provision also must be made to prevent exceeding the maximum allowable discharge pressure and drive motor amps of each compressor in the system. Pressure drop in the distribution system and in hoses and flexible connections at points-of-use results in lower operating pressure at the points-of-use. If the point-of-use operating pressure has to be increased, try reducing the pressure drops in the system before adding capacity or increasing the system pressure. Elevating system pressure increases unregulated uses, such as leaks, open blowing, and production applications, without regulators or with wide open regulators. The added demand at elevated pressure is termed “artificial demand,” and substantially increases energy consumption.
What Causes Pressure Drop?
Any type of obstruction, restriction, or roughness in the system will cause resistance to air flow and
cause pressure drop. In the distribution system, the highest pressure drops usually are found at the points-of-use, including undersized or leaking hoses, tubes, disconnects, filters, regulators and lubricators (FRLs). On the supply side of the system, air/lubricant separators, aftercoolers, moisture separators, dryers and filters can be the main items causing significant pressure drops. The maximum pressure drop from the supply side to the points-of-use will occur when the compressed air flow rate and temperature are highest. When selecting filters, remember that they will get dirty. Air Technologies will help you to ensure that products meet the desired specifications for differential pressure and other characteristics. The distribution piping system often is diagnosed as having excess pressure drop because a point-of-use pressure regulator cannot sustain the required downstream pressure. If such a regulator is set at 85 psig and the regulator and/or the upstream filter has a pressure drop of 20 psi, the system upstream of the filter and regulator would have to maintain at least 105 psig. The 20 psi pressure drop may be blamed on the system piping rather than on the components at fault. The correct diagnosis requires pressure measurements at different points in the system to identify the component(s) causing the excess pressure drop. In this case, the filter element should be replaced of the filter regulator size needs to be increased, not the piping. Air technologies will help you identify your pressure drops and recommend changes.
