Across the wide range of industries today, nitrogen gas is used in many different ways. Companies need a constant supply of high-purity nitrogen to maintain an inert environment or to ensure the quality of their products. No matter the situation, you are sure to find the level of quality you are searching for with On Site Gas nitrogen generators. Buying gas is expensive, inefficient, and can leave you high and dry at times when you run out of nitrogen and can’t receive immediate delivery. So, how does a nitrogen generator work to benefit your business? 

Pressure Swing Adsorption (PSA) nitrogen generation systems have emerged as the premier means for businesses to maintain a continuous, uninterrupted supply of nitrogen for industrial applications. The purity level of nitrogen that PSA systems generate is up to 99.9995%. The systems pay for themselves many times over as they generate nitrogen from the atmosphere around you. Additionally, On Site Gas can build a custom system that is specifically suited to your unique needs. 

The PSA nitrogen generation system uses a method called adsorption to extract the nitrogen from the air. The generator contains two vessels that are filled with carbon molecular sieve (CMS). This sieve material allows nitrogen molecules to escape into a containment area in the generator while it traps oxygen molecules. One vessel is filled with compressed air at high pressure and runs its cycle, then the other vessel takes over immediately to ensure a continuous stream of nitrogen. When the pressure is released on the first vessel, the oxygen is released back into the air and the process keeps repeating itself.

Nitrogen generators are easy to use and require minimal upkeep. However, we strongly suggest that you follow a preventive maintenance plan for keeping nitrogen generating systems running efficiently. As with any of your business’s valuable equipment, maintenance checks are crucial. A simple inspection will ensure that things continue to operate as smoothly down the road as they did at the onset of your purchase.  Every On Site Gas Systems Nitrogen Generator comes with a complete owners manual that will include the recommended maintenance schedule specific to your system.  Please follow this schedule to ensure your Nitrogen Generator is properly maintained at all times.

How to Do a Preventative Checkup for Your Generator

Before you begin maintenance procedures on your generator, you need to verify that the power supply has been turned off.  Then you should start by cleaning the equipment with a damp cloth (steering clear of any electrical components). After wiping the machine down, check the status indicators and look for leaks and inlet air quality by inspecting the control panel on the front of your generator. Your control panel offers status details and indicators to make this step easy.
You should also change your filters regularly to ensure that your system works at peak performance. This step varies depending on how often you use your generator and the type of filters the system requires. Typically, you only need to replace carbon filters once a year, but you should change coalescing filters every six months. Meanwhile, particulate filters require replacement every three months.
One last thing to keep in mind is your T70X-V or N-1100 analyzer. You should replace the analyzer sensor immediately if you have not changed it in over a year. Valve maintenance and Zirconia oxygen sensor replacement, on the other hand, are generally necessary every three years. After replacing the necessary maintenance items, you can restart your generator according to the appropriate start-up procedure.
Although all systems vary, it’s typically best to conduct a preventative maintenance check-up every six months. However, you should check your system’s specific manual to verify the recommended operating procedures.

How to Know When Your Generator Needs Service

While inspecting your generator system, it’s important to look for any signs that indicate a need for service from a professional technician. These may include:

• Water or oil within the filter housings.
• Abnormal sounds or unusual processes during operation.
• Changes in your purity level.

Regardless of how big or small the problem may seem, it’s always best to have anything out of the ordinary checked out before it leads to serious damage. Luckily, the experts at On Site Gas are here to help you address a variety of generator needs.

Does your brewery or winery still use delivered nitrogen cylinders for pressurizing and preserving your spirits? If so, you could be spending unnecessary money. At On Site Gas, we sell permanent and portable PSA and nitrogen membrane generators that can save you money and enhance your business operations.

Types of Nitrogen Generators for Breweries and Wineries

Nitrogen generators work by separating and removing oxygen from the air so only the nitrogen is left. The nitrogen is then stored in a tank to be used in the beer and winemaking process. There are several types of nitrogen generators available for use in wineries and breweries, including:

• PSA Nitrogen Generators – These systems offer stable gas costs, low energy usage, and high purity (up to 99.999 percent).
• Membrane Nitrogen Generators – A membrane system may be a perfect solution if higher purity is not required.
• Engineered Nitrogen Generator Systems – These generators can be completely customized for your brewery or winery.
• Nitro Blast Generator – This type of generator is great for beverage tap systems, including beer dispensing.

Benefits of Nitrogen Generators for Breweries

A generator can save you anywhere from 40 to 75 percent on your nitrogen costs and provide you with a reliable source that will never run out or leak. Beyond saving you money, nitrogen generators offer a myriad of benefits for breweries. These are just some of the ways a generator can improve your operations:

• Can be used in conjunction with carbon dioxide
• Helps pressurize kegs
• Helps prevent spoilage
• Can purge tanks between batches
• Creates a more consistent product
• Improves color, flavor, and carbonization

Benefits of Nitrogen Generators for Wineries

Nitrogen gas is used to displace oxygen during the winemaking process in order to preserve flavor and prevent spoilage due to contamination. Wineries typically use nitrogen for flushing, sparging, blanketing, and bottling. Flushing is needed during the transfer stages in order to purge pumps, hoses, and transfer containers. During the fermentation stage, nitrogen is added as tiny gas bubbles to remove oxygen – a method known as sparging. Blanketing is the process of pushing nitrogen through bottles, barrels, and tanks in order to remove oxygen prior to storing the wine.
It is estimated that wineries can save between 40 and 80 percent on nitrogen costs when they choose to install a generator versus renting cylinders. Not to mention, you’ll be improving your winery’s environmental friendliness.
Here are just a few more of the many benefits of nitrogen generators for wineries:

• Improve your ROI and profit margin
• Never run out of nitrogen
• Prevent nitrogen leakage, which is common in cylinders
• Reduce wasted wine due to spoilage

Are you considering purchasing a nitrogen generator and wondering how much they cost? These systems can cost anywhere from a few thousand dollars to more than $30,000, depending on the size of the generator and your specific needs.
Let’s take a look at how to determine the cost of a nitrogen generator.

How Much Nitrogen Do You Use?

Before you purchase a nitrogen generator, it’s important to determine how much you use on a daily, weekly, and monthly basis. If you’ve previously used nitrogen cylinders, an easy way to determine your average usage is by examining your past purchases. What was the volume of gas in those cylinders? How much did they cost to rent, and did you run out of nitrogen at any point?

What’s the Ideal Purity of Your Nitrogen?

Nitrogen generators have the ability to produce purities of up to 99.999 percent.. In addition to determining your purity level, you need to know the required flow and outlet pressure. These three variables will help to determine the cost of your equipment.

What Type of Nitrogen Generator Do You Need?

Nitrogen generators typically come in two forms – stationary and portable. Stationary nitrogen generators do not move; once they are installed, they must remain in place. Portable generators, on the other hand, can be moved using a trailer system. Your cost to purchase will depend on the type of system you need for your business.

How Nitrogen Generators Can Save You Money

For many businesses that require nitrogen, the go-to solution is to rent cylinders because it’s fast and reasonably reliable. However, these tanks usually never get emptied and you are wasting as much as 20 percent of the encased nitrogen. Cylinders must also be transported within your facility, which can lead to workplace accidents and an increase in workers compensation claims.
Unlike nitrogen cylinders, on-site nitrogen generators provide a constant supply of nitrogen directly on your property, you won’t have to worry about the risks associated with transportation. Therefore, while there is an initial investment to purchase a nitrogen generator , purchasing one could save you money in the long run.
