If you currently use nitrogen cylinders in your bar or coffee shop, you know the vital role nitrogen plays in achieving a perfect pour. With the right ratio of nitrogen, you can serve beer that’s perfectly carbonated, with the smooth mouth-feel that your customers love. But how much money do you spend in replacing those nitrogen cylinders on a regular basis?
Fortunately, your business can make the switch to a Nitro-Blast system. This turn-key solution is customizable to suit your needs, and is available in both cabinet-style and stand-alone systems.

How Much Money Could You Save by switching to Nitro-Blast?

By switching from nitrogen cylinder delivery to a Nitro Blast system from On Site Gas, you can save money. With an up-front cost of around $5,500, most machines pay for themselves within a year or two.
Additional Benefits
Your business can enjoy on-demand nitrogen, eliminating monthly deliveries; you can use as much or as little as your business dictates. You’ll also save on cylinder rental, delivery, and transportation charges, and you won’t have to calculate for price fluctuations from your gas supplier, allowing you more accurate and confident budgeting.
Traditional nitrogen cylinders take up valuable square footage within your restaurant, bar, or cafe. With Nitro-Blast, you can have your system wall-mounted to save floor space and avoid the risk of potential injury (since employees won’t have to handle heavy cylinders).

Nitro Blast For Microbreweries

For microbrewery owners, margins in taprooms are now higher than in distribution, so offering a unique experience that includes nitro-brew is a strategic way to increase traffic. You can also enjoy the versatility of offering beers with and without nitrogen.
Although nitro beer is still a relatively new concept, the nitrogen generator business is not; we’ve been in the industry for more than 25 years and have the experience and resources necessary to serve you.

OnSite Gas Solutions for Food/Beverage Storage and Packaging

At OnSite Gas, much of our fine-tuned technology has applications in the packaging realm. Through the process called modified atmosphere packaging, our nitrogen generators can be used in the storage and packing of fresh and processed foods and beverages: wine, coffee beans and grounds, fruits and veggies, packaged snacks, and more.
Using nitrogen to buffer food products from oxygen and moisture — two agents that can hasten spoilage — modified atmosphere packaging keeps them fresher longer. The gas also helps vintners stave off the vinegary influence of oxygen at every stage of the winemaking process, from flushing and sparging to bottling.
Our nitrogen generation systems can integrate with just about any form or method of storing and packaging, from vertical form filling and canning to shrink-wrapping and bagging.
OnSite Gas nitrogen generators are also perfect for rendering the controlled atmosphere storage necessary to precisely manage oxygen levels and maintain a particular ripening timetable of stored fruits and vegetables. It can also be used on the processing side of things to ward off pests and store ingredients.
From a small boutique winery to a huge food distributor, OnSite Gas delivers innovative nitrogen-generation setups to satisfy your storage and packaging needs. And if you’re among our fellow exhibitors or attendees at PACK Expo International Trade Show, we’ll see you in Chicago this November.

If you’ve frequented a coffee shop over the past few years, you might know that cold brew is becoming a hot commodity.
Some might confuse cold brew with iced coffee, but the two have fundamentally different preparations, and connoisseurs will be quick to point out a vast difference in quality. Iced coffee is traditionally brewed hot coffee that’s been chilled with ice. In contrast, cold brew derives from grounds that have been soaked for an extended period of time in water at room temperature (or that’s been chilled).
So what’s the fuss about cold- versus hot-brewed coffee? In boiling water, the oils in coffee grounds tend to oxidize and the acids break down, which can result in a bitter tang and the loss of nuanced flavor notes. But in room-temperature/cool water, those processes are slowed down significantly, lending cold brew a smoother, deeper, richer, sweeter flavor.
Traditional cold brew is all well and good, but customers are beginning to notice how luxurious this coffee can be with the simple infusion of nitrogen bubbles.

Nitro Coffee

Fans of craft beer are likely familiar with taps “on nitro.” Carbon dioxide creates the traditional head on beer, but a nitro brew is infused with nitrogen (or a nitrogen-CO2 combo) to create a creamier froth exemplified by the world-famous (and exactingly poured) Guinness stout. (Guinness pioneered nitrogen infusion.)
Technological innovation has allowed a similar method to boost cold-brewed coffee. Priming cold brew with tiny nitrogen bubbles, letting it sit one or two days, then pouring it through a restrictor plate to stimulate the gas, takes the libation to a whole new level and gives it a smooth, buttery, luscious mouthfeel. Some coffee drinkers accustomed to adding cream and sugar to their mugs find these ingredients unnecessary in nitrogen-stocked cold brew.
As with beer, either pure nitrogen or a blend of nitrogen and CO2 in varying proportions can be used depending on the desired flavor profile.
As java gourmands fall in love with the velvety charm of nitro coffee, more coffee shops (and amateur cold-brew fans) are integrating nitro capabilities into their operations. On Site Gas Systems recently debuted the Nitro-Blast setup, which is perfect for cranking up your cold brew.

Other Embellishments That Add to the Nitro Cold Brew Experience

The nitro makeover may be the most talked-about enhancement to cold brew these days, but there are plenty of other ways to tweak your cup. Common finishing ingredients to cold brew include salt and chocolate.
Ready to enhance your already delicious cold-brewed coffee? Turn to On Site Gas to take advantage of our state-of-the-art nitrogen generators, and embrace the creamy goodness that nitro coffee delivers. Contact us today to learn more about our offerings.

Various industries, hospitals, and businesses may feel like they have no other option than to get cryogenic gas delivered in bulk to meet their nitrogen and oxygen needs. But this is not the case. On Site Gas makes it possible for these facilities to generate their own nitrogen and oxygen by means of an O2 & N2 Site self-generating system. When compared to cryogenic gas, these systems offer a variety of advantages.
Advantages of O2 & N2 Self-Generating Gas Systems

Ease of Use

No contracts to sign, you can purchase, lease or rent nitrogen and oxygen generating systems.

Low Maintenance Costs – System Can Last for Decades

Regular maintenance helps our nitrogen and oxygen generators last for decades.

Portable

Many of the O2 & N2 Site systems offer portability. These systems can be used anywhere that electricity and air are available. These systems are even usable in harsh conditions and extreme climates.

Less Expensive Than Purchasing Cryogenic Gas

The O2 & N2 Site gas generating systems are economical. The typical cost per CCF of the self-generated gas systems ranges from one-third to one-half of the costs associated with purchasing cryogenic gas.

No More Concerns About Running Out of Gas

Any concerns related to running out of gas are eliminated because the O2 & N2 Site system generates its own gas.

Pressure Swing Adsorption (PSA) and Membrane Technologies – How They Work

The O2 & N2 Site systems have two ways of generating gas: membrane technology or PSA.

The Process of Pressure Swing Adsorption

That is adsorption, not absorption. These two words may look similar, but they mean two very different things. Adsorption differs from absorption in that absorption is a chemical process, whereas adsorption refers to the physical process of actually separating gas molecules from one another.
PSA systems are designed to generate both N2 and O2. Compressed air is used to pressurize a vessel that is filled with zeolite or carbon. Zeolite and carbon separate molecules according to their structure or physical composition.
The forcing of air into the vessel causes either the O2 or N2 molecules to become trapped; meanwhile, the other gas floats free. As pressure releases, the O2 or N2 molecules are drawn off and collected in the tank. The captured molecules of unwanted gases are released into the air via a pressure release valve. These unwanted gases immediately recombine into ambient percentages.
Our systems consist of two sieve beds working at opposing ends of the cycle. This ensures there is constantly a consistent flow of O2 or N2.

The N2 Membrane – How it Works

The membranes in our systems consist of a series of hollow fibers that have holes in their walls. These holes are small enough to allow O2 molecules to escape. These molecules escape when pressure within the fibers increases.
These holes are too small to allow N2 molecules to escape. Therefore, when air is forced down the fiber, the O2 molecules exit the fibers and the N2 molecules are captured in the fibers at the opposite end.
The air within the membranes is typically heated. Heating the air excites the molecules, which increases the chance that they will exit through the holes in the fiber.

Our Nitrogen and Oxygen Generating Systems Are Durable and Versatile

Our nitrogen and oxygen generating systems are used across essentially every conceivable place where these gases are needed. We build our N2 and O2 generator systems under the assumption that they need to operate for decades.
That is why our nitrogen and oxygen generating systems are used even in the most remote places on the planet, at numerous combinations of hertz and voltage as well as under the most extreme climates. In fact, our portable oxygen generators are saving the lives of military personnel, no matter where they are located.

Large amounts of nitrogen are essential to the nickel extraction process. Without nitrogen, the nickel mining process can be shut down with a loss of production.

How Nitrogen Gas is Used in Nickel Mining

When raw material is extracted from nickel mines, it travels “as is” to the processing facility. In the processing facility, nickel is separated from the raw material and captured for further processing. Nitrogen is a key part of this process; without large volumes of nitrogen, the nickel extraction process will inevitably come to a standstill.

Why On-Site Nitrogen is Crucial for Mining in Africa

The nickel mines in Africa are often in very desolate or remote locations, making it nearly impossible-or at least extremely expensive-for liquid nitrogen to be used. Not only that, but having to rely on liquid nitrogen deliveries can often leave mines without the supply they need to continue the nickel extraction process. If the mine is required to shut down because of a lack of nitrogen gas supply, it can result in over $1,000,000 per day of lost revenue, depending on the size of the mine.

On the contrary, with an on-site nitrogen membrane generator, the nickel mines in Africa are able to create their own consistent supply of nitrogen gas. They won’t be shut down because of bad weather or other delays of the delivery trucks. On-site nitrogen gas is the only way for mines to have a reliable, stable nitrogen gas supply to keep them operating at maximum efficiency.

Why Nitrogen Membrane Generators from On Site Gas Systems

We are known worldwide for our nitrogen membrane generators that provide mines with a dependable nitrogen gas supply. Our on-site nitrogen systems are available for long and short-term usage, as well as either for rental or for purchase. They can produce nitrogen gas at a purity up to 99.9% and a volume up to 6000 SCFM. There is no location too remote for our nitrogen membrane generators, and there is no application too complex.
