On testing we are arguing against adding concentrate to premix. We are told by chemical company it should not degrade but I would prefer to hear from all you users experience with premix.

Next question, the consensus seems to be Pre-mixed OK? When we require testing of antifreeze solutions, and in 13D re-mixing to maintain concentrations, there must be some separation going on, right? So how will we deal with higher concentrations that may occur over time? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of George Church Sent: Wednesday, September 22, 2010 10:11 AM To: [email protected] Subject: RE: Anti Freeze for commercial We've likewise used AF to be able to install CPVC in existing attics where steel would be a nightmare, or other things like avoiding 30% increase in MRA off a limited water supply. I'm not a registered design professional, but ones I've talked to about this seem to agree the premix is fine. Items to watch for in addition to the obvious concentration are high pressure which leads to smaller droplets and existence of devices/equipment with open flames that could provide the spark like the unit heater in NJ, or coking facilities. Yes, Roland, NFPA limiting it to residential missed restaurants which could have AF, have done them, but in PA we're using premix so we believe we don't have a problem revealed in Ph 1 or 2 testing, and we're watching for the release of further testing to prove to the point NFPA desires that we continue to have a high level of confidence in the premix concentrations. glc _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
