Our on site nitrogen and oxygen generators are simple to use and don’t require much upkeep. However, just like most things you use on a regular basis, annual maintenance is strongly recommended. Here is a look at what questions you should ask yourself to see if it is time for maintenance on your oxygen or nitrogen generator, as well as an overview of why this maintenance is so important.

Questions to Ask

If you are unsure if your nitrogen or oxygen generator is in need of maintenance, you simply need to ask yourself these seven questions. If you answer yes to any of them, maintenance is very strongly recommended.

• Does the HMI show any maintenance messages? This is a clear indicator it is time to have your oxygen or nitrogen generator looked at.
• Has it been more than 5,000 hours since the last maintenance service was performed? If so, it is a good idea to have it checked again.
• Can you see any water or oil within the filter housings? This should not be present and should be looked at.
• Do you hear any abnormal sounds or notice any unusual processes as your nitrogen or oxygen generator is working? It is always better to have them checked and have them be nothing than to ignore them and have them lead to serious damage.
• Is your purity level the same as it was when you first received the oxygen or nitrogen generator? If it has changed, schedule maintenance ASAP.
• Have you changed the filters recently? They should be replaced on a regular basis depending on how often you use the generator and the type of filters the system uses. Particle filters usually need to be changed every three months, while coalescing filters should be changed every six months, and carbon filters need to be replaced once per year.
• Does your system have a T70X-V or an N-1100 sensor? If so, when was the last time it was changed? If it has been more than a year, it should be replaced now.

Why Maintenance Is Crucial

Even though maintenance to your nitrogen or oxygen generator may seem burdensome or unnecessary, trust us; you will be glad you took the time to do it. Regular maintenance will help catch small issues before they become major ones. It will extend the life of your nitrogen or oxygen generator, and it will make sure your equipment is operating at its best.
If you don’t want to have to think about maintenance for your oxygen or nitrogen generator, you can take advantage of our Annual Maintenance Program kits. Each one includes the filters and the elements that need to be replaced on your specific equipment each year.

When you know the benefits of a nitrogen generator or an oxygen generator, but you want to save yourself some money, looking at used equipment is an obvious next step. However, when purchasing used oxygen and nitrogen generators, you can’t just purchase them from anyone.
While it is common to turn to eBay or Craigslist when looking for used goods, a nitrogen or oxygen generator is something better purchased from the pros. If you buy one from a stranger, you will have no idea the history of the equipment, if it was maintained properly, and how long it was used for. You also have no guarantee if something does go wrong.
At On Site Gas Systems, we sell both used nitrogen generators and used oxygen generators, but with our used equipment, you can have peace of mind. Here are five reasons why you can trust On Site Gas Systems with a used generator purchase:

Same Great Product

We sell both previously used and demo equipment at a fraction of what it cost new. But even though it isn’t brand new, it is still our reliable, trusted equipment that we have been building for nearly 30 years. Each of our oxygen and nitrogen generators includes advanced features, like touchscreens, and operate with extreme efficiency to keep the operating costs low.

Built to Last

At On Site Gas Systems, we have been paving the way for on site oxygen and nitrogen generation for almost 30 years, and we only use top-quality materials that are guaranteed to be durable. In fact, some of the generators we built at the very beginning are still going strong. Just because the equipment is used, it still has a lot of life left to give.

Factory Warranty

When you buy direct from us, your used nitrogen generator or oxygen generator still comes with its original factory warranty (length varies by model). You don’t have to be nervous about getting a faulty machine, because if there are any manufacturer defects, they will still be covered.

Huge Savings

As with anything else, when you purchase used, you can save yourself a hefty sum of money. For example, we currently have an N-25-T nitrogen generator on sale for $5,900, when its list price was nearly $16K. Of course, our prices and availability are subject to change, but that’s just an example of how big your savings can be when you buy used from us.

If you are a brewer or a bar, you know how important the mouth feel is to the beer you are making/serving. It is everything. When a beer has a better mouth feel, it is more enjoyable to drink and provides a more immersive experience. So it’s no surprise that nitro beer is becoming very popular. Here is a closer look at what a nitro beer is, as well as a discussion of the various terms it goes by, including nitro beer, nitro brew, and nitro pour.

What Is a Nitro Beer

As you know, traditional beer uses carbon dioxide to achieve the carbonation effect that beer is famous for. Recently, brewers have started integrating nitrogen into the brewing process instead of just carbon dioxide. Most commonly, a 70-30 ratio is used: 70% nitrogen to 30% carbon dioxide. The seemingly simple change in the gas usage has quite a big impact on the finished product. The reason is because nitrogen does not react as it dissolves in water like carbon dioxide does, which results in:

• A smoother, fuller mouth feel. Many describe the feel more like a milkshake than a beer.
• A larger, longer-lasting head. Instead of quickly dissolving after the beer is poured, a nitro brew will retain its impressive head.
• A different appearance in the bubbles. Instead of the bubbles looking like they are rising, they look like they are falling, which is just fun to look at.

Nitro Brew, Nitro Beer, Nitro Pour?

Chances are, you have heard all three of the above terms used, but are they talking about different things? In short: no. A nitro brew, a nitro beer, and a nitro pour are all the same thing. However, you will need a specific faucet to pour a nitro beer, which is what some people may be referring to when the say nitro pour. Otherwise, all three terms merely mean a beer that was brewed with a majority of nitrogen gas.

Choose On Site Gas for Your Nitro Brew

While you can always get nitrogen gas delivered to your brewery or your bar every time you need it, there is a better way. With our Nitrogen Blast, you can make your own nitrogen whenever you need it. There is no dealing with the hassles of storing cylinders and arranging for deliveries, and there is no worrying about running out and having to stop production. At On Site Gas Systems, we are your partner in on site nitrogen gas. We have been helping brewers and bar owners make their job easier for nearly 30 years, and we would love to help you too.

If your facility uses nitrogen gas, there is a good chance you have at least considered switching to a nitrogen generator. But if you are like most manufacturers, the first question you have may be what are the real nitrogen generator cost savings? They are probably greater than you realize. Here is a breakdown of the nitrogen generator price after the long-term.

Factors That Impact the Nitrogen Generator Price

The true nitrogen generator cost is much more complex than simply the initial upfront cost. You have to factor in how much you will save when you don’t have to deal with nitrogen cylinders, as well as how the nitrogen generator will impact your efficiency, reduce your waste, and cut back on employee accidents. When including all of these nitrogen generator cost savings, many of our clients recoup the upfront cost of a nitrogen generator within a year, or quicker. Heres a more detailed breakdown:

• No More Nitrogen Cylinders – Just imagine completely eliminating the never-ending overhead expense of nitrogen cylinders, including the charge for the gas itself, as well as delivery charges, fuel surcharges, tank rental fees, etc. When you have your own nitrogen generator, you can say goodbye to them forever. Once your nitrogen generator is paid for, you will have very little overhead as far as your nitrogen supply is concerned.
• Less Product Waste – Did you realize that as the nitrogen cylinders are being stored at your facility, they are losing volume? On average, 10% of the tank you paid for may be wasted by the time you use it. Plus, you have to deal with the floor space to store them, which is a waste in itself. With an on-site nitrogen generator, you can make the nitrogen as you need it, so none of it is wasted.
• Reduce Employee Accidents – Liquid nitrogen is harmfully frigid (its -320 degree Fahrenheit), and, unfortunately, there are sometimes storage leaks with cylinders. This puts employees at risk of burns and skin damage. With your own nitrogen generator, these risks are eliminated.
• Increase Workplace Efficiency – When you don’t have to worry about the logistics of nitrogen cylinders, and you dont have to risk running out of your supply, your entire operation can run smoother.

As you can see, when looking at the true nitrogen generator costs, the decision to purchase one is a no-brainer. While the upfront capital may seem like a lot, when you break it down and realize how much you will be saving, you can clearly see it is the best long-term decision.
