What Determines The Nitrogen Generator Price?

By Janine Hughes


The decision to invest in a nitrogen generator can be a very wise decision, particularly due to the fact that the gas is always in high demand. However, before emptying your bank account, it is very important that you take time to conduct a background check, compare prices, the available options, and match them to your unique requirements and preferences. Normally, return on investment should be within two years if it can operate at 70% capacity or more. In order to succeed in background check and feasibility study, you need to grasp the factors that determine the nitrogen generator price.

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.

Generally though, the generators can be broadly categorized into three. These are the small flow, the medium size, and the large flow. The small flow generators have a price range from $3,000 to $20,000. The medium flow goes for $20,000 to $100,000 and the large flow for anything above $100,000. However, these are just estimates and it is possible to get a quote above or below the said range.

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.

The oxygen analyzer is the other factor. Since the process is very critical, the oxygen level has to be monitored all the time. In case where the customer requires pressure above 200 psig, a booster will be required to elevate the pressure to the required level. This further increases the overall quote.

The other additional feature is the oxygen analyzer. The process is very critical and the oxygen level cannot go unchecked. Other than this, the pressure required is an also an issue. Anything above 200 psig requires installation of a booster for the purpose of increasing the pressure to the required level.

The feed air compressors are also the feature that should concern the buyer, particularly in situations where the compressed air is not available or there is no are compressing capacity on the part of the buyer. Fully dedicated air compressor and a compressed air dryer are all additions that are going to drive the overall cost higher. It does not matter if the generator is a membrane type or a PSA, at the end of it all, the air has to be dry and compressed.

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.
