MAXIMUM VOLUME OF ENCLOSURE THAT CAN BE PROTECTED BY THE LB SSP SYSTEM MAXIMUM VOLUME OF ENCLOSURE THAT CAN BE PROTECTED BY THE LB SSP SYSTEM MAXIMUM VOLUME OF ENCLOSURE THAT CAN BE PROTECTED BY THE LB SSP SYSTEM Table - Maximum Volume Enclosure for lb System Minimum enclosure temp Maximum hazard volume ft Design concentration number Table - Maximum Volume Enclosure for lb System Maximum hazard volume ft Minimum enclosure Design concentration number temp Table - Maximum Volume Enclosure for lb System Maximum hazard volume ft Minimum enclosure Design concentration number temp PRE-ENGINEERED SYSTEM CALCULATION GUIDE CHOW TO DETERMINE THE CORRECT SSP SYSTEM FOR YOUR APPLICATION Step Identify the hazard to protect and note the applicable design concentration number Example Hazard is Class C Energized required Round up design concentration to next whole number Electrical Control Cabinet W ft L ft H ft Table - Hazards to Protect Flammable Liquid Design Concentration v v Flammable Liquid Design Concentration v v -Butane -Propanol - trimethylpentane -butoxyethanol Acetone Acetonitrile Commercial Heptane Commercial Hexanes Cyclohexane lsooctane Isopropanol Alcohol Methane Methanol Methyl Ethyl Ketone Methyl Isobutyl Ketone Methyl Tert Butyl Ether n-Heptane n-Heptane Cyclopentanone Octane Denatured Alcohol EtOH Propane IPA and MeOH Diesel Fuel Pyrrolidine Diethl Ether Technical Heptane Ethanol Tetrahydrofuran Ethyl Acetate Toluene Gasoline- oct unleaded Transformer Oil Class A Hexene de-energized Class C Fires N ote Design Concentration for Class B Fire are shown in the above table and includes a safety factor from the minimum extinguishing concentration Table - Flooding Factor Numbers Design concentration number F F F F F F F F F F F Step To identify the ooding factors number determine the enclosure ? s minimum temperature and align this with the rounded up design concentration number in Table left Example Minimum temperature is F rounding up number is therefore ooding factor number is Step Calculate cubic feet of enclosure by multiplying the width x length x height To identify required system size multiply cubic feet of enclosure by the ooding factors number Example Enclosure is ft W x ft L x ft H cubic feet x This would round up to the lb system Step Use Table to double check that the enclosure to be protected does not exceed the maximum area coverage of the tested nozzles and the volume coverage does not exceed the maximum hazard volume of enclosure in Table Example The enclosure is ft and the max coverage of lb nozzle is ft The lb system can protect up to ft at F with a design concentration of System lb lb lb Table - Maximum Area Coverage Max area coverage ft ft ft C
