Not trying to bash BOC....
I did the quote round robin with gas suppliers recently and emailed the results to the GM and account managers.
It made interesting reading.
Anyway, I asked the question at BOC regarding specs for Nitrogen.
No one seemed to know so we discovered the difference between the two specs, industrial (032) and high purity (034) could be impacting some of our jobs.
A number of us had been sourcing the nitro from the local independent refrig wholesaler as it was high purity from A-Gas.
Their price was the same as BOC's industrial spec, which had higher levels of oxygen and more importantly for us, moisture.
One of our account managers, who is very technically switched on was surprised at the difference in specs as they'd just been grabbing 'nitro' from BOC, which was the industrial spec.
At least everyone here has been taught to use a vacstat and all the boys, including the apprentices posses them, so it's never been an issue.
Having said that BOC's pricing to us on oxy/aceylene and consumables and even things like regs is very competitive, we definitely don't pay retail, so they can do it if they want to.
As an aside, the local independent wholesaler absolutely flogs the big national wholesalers on refrigerant pricing, at times to the tune of 25% better.
I needed R407c for a small (80kw) chiller the other day and thought I'd give the big guys a shot again as they've been angling for our gas purchases and was shocked at the difference in refrigerant pricing, they were no where near what we normally pay.
