I really appreciate the responses. I was looking for confirmation that my thinking was correct. I lost a couple of bid jobs recently, one which was a modification to an existing antifreeze system, essentially tripling the size of the system, and the other was a wet and dry system.
I expected to lose the job that modified the antifreeze system. I talked with the engineer prior to the bid but was told to bid what was shown and it would be modified after the bid. The combination system I knew I had a good price and was surprised when it was given to another local company (same company that is doing the other project). Well, I was curious so I visited the job site yesterday and was very surprised to see the antifreeze loop ( this is Northern Michigan, Marquette area) instead of the dry system. This shed some light on the bid. I just wanted to make sure that my thought process was correct and that I really shouldn't be installing antifreeze systems, at least not with what freeze point solutions are currently available. -- Craig Leadbetter Safeguard of Marquette PO Box 116 Marquette, MI 49855 (O) 906-475-9955 (F) 906-475-5474 (C) 906-362-5393 [email protected] On Mon, Aug 5, 2013 at 12:47 AM, Rod DiBona <[email protected]> wrote: > Craig, > > www.nfpa.org/antifreeze has the information you are looking for.
