Nitrogen Gas Prices, May 2017 We have talked before about comparisons between disposable Nitrogen and high-pressure industrial nitrogen cylinders and in that post we indicated the various set-up costs along with the annual costs of nitrogen based on the volume of nitrogen used. In this post we are providing pricing information on the disposable nitrogen bottles and comparing them with high-pressure nitrogen bottles that are supplied by companies like Rentfreegas. Disposable Nitrogen Bottles All Nitrogen cylinders must state their volume and pressure on the cylinder, as this is a requirement within Australia. The pressure of the disposable nitrogen bottles (shown below) is 10,000kPa with a nitrogen gas volume of 0.22m3, and tare is 1720g. The cost is somewhere between $83-$96 per bottle depending on the supplier. Nitrogen Disposable Bottle Volume 0.2m3 (2.2L) High-Pressure Nitrogen Bottles Nitrogen supplied in industrial high-pressure cylinders have a greater volume than the disposable bottles due to the pressure being greater within the cylinder. The fill pressure on the C size bottle is 200bar (or 20,000kPa) which is twice as great as the disposable bottle fill pressure, and the cylinder contains 600 litres of nitrogen. The C size bottle is a standard Australian approved cylinder and for nitrogen comes with a Type 50 valve outlet so your existing regulator will fit. The refill cost is $70 including postage to you. To do a fair comparison you need to also include the cost of return postage for the sending the empty back to us (approx. $20) and therefore the cost is $90. So, for a similar price of around $90 you can have 3 x times as much gas. There is a first cost to purchase the cylinder, with gas and delivery to you, and that is $220. The weight of the cylinder full of gas is around 6kg and it stands 55cm tall (as shown below). C Size (600L) If you are planning on using nitrogen over the next few years then the investment in your own cylinder [...]
Dry Nitrogen Tank with No rent HVAC businesses in Australia can now access Nitrogen in many forms. They can purchase industrial high-pressure cylinders from the big gas companies like BOC, they can purchase disposable nitrogen bottles from Bunnings and they can also purchase rent free Nitrogen tanks from various suppliers.Even customers in remote Australian regions have access to C size high-pressure Nitrogen bottle that comes to your door via TNT or Australia Post. The key in deciding what cylinder size, supplier or model to use (that is, whether to rent or buy a bottle) is to understand how much gas you use and then look at the volume of the each cylinder, whether disposable or high-pressure. Option 1 - If for example you only use small amounts of nitrogen (say 2m3 p.a.) then the investment in a disposable nitrogen regulator (approx. $70) and disposable cylinders (approx. $400) could be the most cost means of buying nitrogen. Please remember that these regulators for disposable cylinders, do not work with Industrial high-pressure cylinders, which have a Type 50 valve outlet. Outlets like Bunnings sell disposable nitrogen cylinders. Option 2 - If however, you use a medium (for example 2m3-10m3) amount of Nitrogen then a rent free Nitrogen bottle could be the most cost effective means of buying Nitrogen, (expected cost $550). Regulators cost between $100 for 0-1000kPa or $350 for the high pressure & high flow regulator. Option 3 - If you are a large user of Nitrogen and have service vehicles on the road, then the most cost effective way to purchase Nitrogen might be through someone like BOC where the cost of gas is cheaper, and the rental costs balance out with buying your own bottle.

When it comes to the question of where to get nitrogen gas, you can't go past Rent Free Gas. Renting a cylinder may seem like the obvious option, but think about it – do you really want to be paying every month for something that might sit in your shed for a year? Rent Free Gas is where to get nitrogen gas cylinders that are yours to keep. Where does nitrogen come from? Every time you breathe, you're inhaling mainly nitrogen. Where to get nitrogen gas? It's literally everywhere! Nitrogen makes up almost 80 percent of the earth's atmosphere. Where to get nitrogen gas for your projects Nitrogen may be everywhere, but we know that's not what you're really thinking. The question really is 'where do I get nitrogen gas so I can use it for my DIY, commercial and industrial applications?' Before we can recommend where to get nitrogen gas at great prices and without even paying for delivery in metro areas, let's take a look at how that nitrogen gets in the cylinder in the first place. How nitrogen gas gets in those cylinders The process of extracting nitrogen from the air and separating it for you to use is called 'fractional distillation'. First, the air is filtered so that particles like dust are removed. Next, it is cooled in several different stages until it reaches the temperature of minus 200 C. At this temperature, 'air' is not really 'air' anymore – it's liquid. When that air turns into liquid, water vapour is removed with absorbing filters. At about minus 80 C, C02 freezes, so that's easy to remove. And because oxygen turns into liquid at a slightly warmer temperature than nitrogen, it's not too hard to separate them. Nitrogen gas from Rent Free Gas The most common use of our nitrogen gas cylinders is welding, and it's great for purging and blanketing but it's also a great way to reliably and efficiently inflate [...]
