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.

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).

If you are planning on using nitrogen over the next few years then the investment in your own cylinder makes sense, with the same refill cost providing 3 x times as much nitrogen.

Thank you.
