Consider These Factors When Purchasing an Oxygen Generator

Oxygen generators have a range of applications, from providing vital life support to medical patients, to aerating wastewater, promoting biological treatment, boosting the yield of gold mines, and helping hatchery trout thrive. On Site Gas Systems offers a comprehensive range of top-quality oxygen generators for a wide variety of purposes.
Whether for commercial, industrial, or medical situations, On Site Gas PSA oxygen generators benefit commercial operations from fish farms to glassblowing; supply oxygen for healthcare purposes (including field-ready portable generators), and serve astronauts aboard the International Space Station. In addition to our ready-to-go turnkey generators, we also design custom oxygen-generation systems for nearly any setting or purpose.
Our systems utilize Pressure Swing Adsorption (PSA) technology. These state-of-the-art PSA generators pass compressed air through a vessel containing zeolite, a molecular-level sieve that filters out nitrogen to provide high-purity oxygen.

Oxygen Purity

What level of oxygen purity do you require? At On Site Gas, our standard-purity generators deliver up to 95% oxygen for many commercial purposes, and our industrial generators provides up to the 99% level required by many industrial applications along with hospitals, clinics, and healthcare providers.* (Our generators produce 99% oxygen by running a 95% concentration through a couple of other processing stages.)

Oxygen Flow and Pressure

Calculate the minimum required flow – in standard cubic feet per hour (SCFH), normal cubic meters per hour (NM3/H), liters per minute (LPM), or whatever other units – for your purposes, as well as the necessary delivery pressure to determine what sort of oxygen-generating setup you require.
If you use a generator to fill oxygen cylinders, account for the influence of cylinder consumption on your flow requirements. Speaking of, at On Site Gas we also provide high-power oxygen filling stations for efficiently stocking your cylinders with 93%, 95%, or 99% oxygen.

Capacity of Your Air Compressor

At the front end of things, can the capacity of your compressed-air unit support the oxygen generator you’re considering?

Oxygen Generator Footprint and Setting

Consider the total footprint of your oxygen-generation system, including the generator, air compressor and any associated tanks or cylinders. Identify a location with the size and infrastructural needs to accommodate it.
Please don’t hesitate to contact us at On Site Gas to meet any of your oxygen-generating requirements. Whether it’s a self-contained portable unit for a frontline hospital or a custom-built industrial installation, we’ve got the oxygen generators you need.
*If you need an oxygen generator for medical purposes, it’s essential to familiarize yourself with local regulations.

Enhance your Cold Brew with a Nitrogen Kick

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.
