Believe me, I think outside the box more often than my design staff is comfortable with. A year ago we had a project that could only be done within the code by using a PLD diesel. PLDs for Tier 3 engines weren't approved yet. BUT- they were in final testing. So we ordered a Tier 3 variable speed engine with our pump and now that the ECM version of the PLD is available, field retrofit it yesterday. FM Approvals rep, local FM rep, Joslyn clark factory rep, local controller rep, Clarke/Deere factory guy with software upgrade and new engine control panel, Aurora pump local reps, our guy and the customer al in attendance. Would have had UL there, too, but its an FM account and they didn't believe it was necessary after I surveyed some friends on the insurance side and they said if it was accepted by FM, didn't need both.
No one else has ever retrofit a PLD like this. Nice thing (except for the $) was that since they make a small selection of variable speed Tier 3 engines, it ran 2104 rpm at churn, 2101 rpm at 150% (4500 GPM!) because its a 572 HP pump, over 100 HP more than we needed and the largest Clarke has. Variable pitch blades in the turbo to maintain emissions, not your father's Oldsmobile. So there are times I stick with tried and true; but the largest project we've completed was performance-based design outside #13 based on Section 1.5 Equivalency. Balance when old stuff is best, not afraid to try something new if it makes sense.

I have no problem with doing things the way they have always been done, but being level 4, I feel bad when someone asks me why I am doing something that way, the only reason I can give them is "Because that is how it is has always been done". This industry needs, young, original thinkers, and old, stodgy thinkers both. -----Original Message----- From: Ron Greenman [mailto:[email protected]] Sent: Wednesday, October 13, 2010 9:29 AM To: [email protected] Subject: Re: Calcium Chloride antifreeze protection Matt, It corrodes steel, it leaks, it's not listed for the use, it's not one of the few acceptable chemicals allowed in 13 . You make your call from info like that. Ethylene glycol lowers the freezing point of water but is poison. Sugar does also but it's a long strand carbon molecule that will burn.. Gasoline freezes at a much lower temperature than water but is probably not a good solution to the problem. Like our discussion on centrifugal pumps and raising water with Rube Goldberg solutions: what George said--you can but that doesn't necessarily mean you should.
