What Determines The Nitrogen Generator Price?

By Janine Hughes


The nitrogen generators come in different sizes, capacities, and make. As such, the prices also vary widely to reflect these differences and many other factors. The major determinants of the overall cost include the type, the size, and the application. However, there are some modifications and additions that may be necessary and can thus further increase the cost. However, a generator that is in 70% operation should recoup its cost of investment within two years. The nitrogen generator price depends on the seller, and the capacity or the size of the machine.

When the seller or the manufacturer receive a request for the price quote, there are several variables they have to put in, and most of these depend on the intended use of the machine, the volume of gas to be generated, and the location.

More often, the suppliers are able to give a quote within two hours. This depends on the type, the capacity, the manufacturer, the model, the year of manufacture, and the market forces of demand and supply. As such, the quote may vary from one supplier to the other necessitating the need to visit several suppliers. Luckily though, an email request or a phone call is enough for this.

It is not just the generator that determines the cost, but the nitrogen buffer tank also matters. Depending on the preferred option, the cost can be higher or lower. Depending on the application, a larger or smaller tank may be required. A constant flow application (blanketing), for instance, requires a smaller tank which is less expensive. In some instances, however, a tank that is capable of supporting a large supply within a short time period may be needed. This kind of intermittent flow calls for a larger tank which is more costly.

Other installations like the oxygen analyzer and pressure boosters also influence the overall cost. The process is so critical that the oxygen level has to be monitored all the time. In some cases, a pressure level exceeding 200 psig may be necessary. This calls for a booster for elevating the pressure level to meet the requirements.

The feed air compressor is also the other feature that can drive up the cost. It is usually necessary in situations where the customer does not have a compressed air system. In some cases, there is no enough pressure for air compressing. However, introducing a dedicated air compressor means an increased cost. In some instances, compressed air dryer may be necessary.

Regardless of the type, whether membrane or PSA, the air has to be dry and compressed. As such, a dedicated air dryer may need to be installed particularly in the situations where air quality does not meet the standards in moisture content.

The said factors are just a few examples of adjustments that might be necessary when installing a new nitrogen generator. All in all, if all the necessary considerations are taken into account, this turns out to be a very profitable venture and gases are always in demand.
