...we really need to compare apples to apples when disscussing fire safety systems. A 2.5lb Halotron fire extinguisher has less than half of the fire suppression capacity of a 2.5lb Halon fire extinguisher. A 2.5lb Halon extinguisher has a UL classificaton of 5-B:C, a 2.5lb Halotron extinguisher has a UL classification of 2-B:C. To achieve the 5-B:C classification with a Halotron extinguisher would require a 5lb unit. The 5lb unit offers 3 distinct disadvantages; first, it has a wall hanging bracket, that would require a vehicle mounting bracket to be purchased separatley. Second, due to size, a 5lb bottle would be more difficult to mount in a car than a 2.5lb bottle. Third, a 5lb Halotron bottle would cost more than a 2.5lb halon bottle(more money to do the same work).

To put the UL clasificatons in perspective: a classification of 2-B:C will suppress 2 square feet of fire, a classifiaction of 5-B:C will supress 5 square feet of fire.

Halotron does have a few advantages, pound for pound it costs less than Halon, though it takes twice as much to do the same work. Halotron also environmentally cleaner than Halon. Here is a link to the Halotron website: http://www.halotron-inc.com/prodinfo.htm .

If Rennlist members would prefer Halotron extinguishers to Halon, I would be happy to look into offering Halotron rather than Halon for this group buy, at a price competitive to what you quoted. Also please bear in mind that the price of the Halon extiguishers have gone up 3 times in the past 12 months and will likely go up again after the first of the year.

Thank you for taking the time to read this post
