Data needed for Castrol Hysol Excel coolant

The range of Hysol lubricants is here:

Might be worth checking that the Hysol XF isn't the same thing?

Might help.

Thanks Peter. I had looked on Castrol's site but couldn't tell if XF was the same thing. A bit more hunting on Buck and Hickman's site found it though, it wasn't linked from the page for the 5l can but was linked from the listing for 60l; who puts their website together? Excel is designed for hard water which is one of the reasons I wanted it; looking at the data sheet, XF is a milky emulsion whereas Excel is clear. Still have no idea why Castrol don't have the data (and I searched the internet archive, just in case they had removed it from their site recently). Martin

Most mainstream oil companies are really dreadful at putting data on the web; you sometimes end up finding data sheets on distributors sites, but you need to recognise that the specs may be different in different parts of the world for (apparently) the same product.

See:-

Copied from a Greek supplier's web site, but refers to Castrol(UK) in Swindon, so we can assume it's the right stuff. Why the hell they haven't got it on their own web site after two years of production I don't know!

I'm using the stuff at 4% in the J&S 1400 grinder and, thus far, the mag chuck and table haven't shown any signs of corrosion on clean ground surfaces after leaving the coolant on and letting it evaporate off. Our water in Rugby is slightly hard (soft compared with Southend, but hard compared with Devon :) and I don't seem to see any problems. I've only had the stuff for a couple of months, but it's looking ok so far.

Mark Thanks for that link, just what I needed. Thanks also to others who emailed me links to the data; as Mark said, Castrol don't have the Excel data on their website and Excel isn't the same as X or XF (although you wouldn't know without actually seeing the Excel data sheet of course). Martin (off to clean the sump and build a skimmer like Nick's).

Windblows?

Windoze from NT4 to 2k3, Solaris, Irix, Linux, HP-UX, AIX (The Vaxen were ok this time :-)

T'was a failure in the backup power supply... It took over the mains after a perturbation, wasn't happy with its output voltage and put itself into bypass mode. The lowered voltage caused switch-mode power supplies to take more current. Took out four distribution board breakers... those feeding the most heavily loaded rows of racks :-(

I have a fix planned (as well as getting the voltage regulator on the supply fixed), Trouble is changing the breakers from B surge rating to D surge rating is a major planned outage. I told the boss that we should have the breakers standing by, then if the s*1t hit the fan again, we could do the upgrade while the machines were down anyway. He wasn't happy about that.

Maybe I can get the work planned for Christmas. I could get a two day outage then, without the customers and users complaining. Don't know if I could get any of my colleagues to help with the work though.
