Thanks Stewart. Have you ever compared the cost of mist to CO2? Ron

Apart from Marioff there are other manufacturers/proprietary systems including Fogtec, Danfoss, Eusebi, Ultrafog and others. Like all applications of this type of technology it is essential that the systems are properly engineered for the risk. I believe that after engine test cells, continuous deep fat fryers were among the earliest land based uses of mist technology. Gas systems, especially CO2, have their benefits (low clean up costs post fire - foam and powder use requires extensive deep cleaning of food manufacturing premises) but there is a serious risk of re- ignition once the gas concentration dissipates Regards Stewart Kidd www.risk-consultant.com On 25 Nov 2008, at 18:49, Fletcher, Ron wrote: > Thanks Charles, we are looking at CO2.
