Diesel fuel life in a standby generator

I'm in the hire game, so unless you want a price for a long term rental unit, then I can't really help. I probably shouldn't go spruking my wares on here anyway.:)

We use a lot of FG Wilson units in our fleet - they are a Perkins powered unit and are reliable and competitively priced. Distributed by Allight in Australia. (No connection to them, Just another thought...:) )

thanks....heaps of help.

alllight, one of the companies mentioned FG Wilson.......

My employer bought an old de-commissioned hospital that has an emergency genset. It gets serviced every 6 months or so. During a recent power outage, the generator ran out of diesel. The boss rang the service company to see why they hadn't topped up the tank last month with the service, and they replied that they have never put fuel in.

So, this generator has been running on the same tank of diesel for 15-20 years. :D

Weeds, I agree with Bacicat about sizing. 88kVA is the go.
My calculations are:

IF Weeds Arse is on the line, THEN Go for the bigger genset if in doubt
Discharge = NO, NO, NO
Money = Someone Else's (NOT Weeds')

I assume the pumps will do the swapover thing on mains operation, but in mains failure mode both may be required to operate at the same time (well staggered start anyway).
You also need to consider the pumps "fault" load - i.e if they're ragged when they try to start.

On the fuel age issue, we had diesel gensets for level crossings that did not have the fuel changed in the 4 years that I was working on them, and they tested fine every week.

FG Wilson are great units, I would look though to dropping a biocide in the tank to stop it growing bugs.

I would tell the company that every six months would be a good idea and that I will happily dispose of the old fuel(in my LR tank):)

I should have mentioned they can be a bit slow depending on who got your email. I'll zap an email to the Sales guy I know and tell him to get everyone to check their emails.:)

Did you send it to the generic sales@allightsykes.com email?
