Chemori 125 is a trademark of Chemori HFC-125. Pentafluoroethane, Chemori 125 is an effective fire extinguishing agent which is safe, clean, electrically non-conductive and is suited for use at low temperatures because it has a low boiling point (-48.5°C (-55.3°F)) which is similar to that of Halon 1301 (-57.7°C (-72.2°F)).
Chemori 125 is a colorless, liquefied compressed gas. It is stored as a liquid and is dispensed in the hazard area as a colorless, electrically-non-conductive vapor that is clear and does not obscure physical vision. It leaves no residue and has an acceptable toxicity for use in occupied spaces at design concentrations for Class A, Class B, and Class C hazards.
Chemori 125 extinguishes the fire by a combination of chemical and physical mechanisms. Chemori 125 does not displace Oxygen and therefore it is safe for use in occupied spaces without fear of oxygen deprivation.
The Engineered concept of Chemori 125 Clean Agent Fire Suppression System allows a range of flexibility in its design parameters. Each application requires an individual flow calculation to determine the quantity of Chemori 125 required for a specific hazard volume and its set of pipes and fittings sizes. The area coverage of each nozzle can be calculated using the Chemori Flow Calculation Software version CR 4.0. Chemori Engineered System has various sizes of the Chemori 125 cylinder ranging from 20 lb, 35 lb, 70 lb, 100 lb, 150 lb, 250 lb, 375 lb, 560 lb, and 1200 lb. These cylinders are super-pressurized with nitrogen to 360 psig at 70 °F and have the operating temperature ranging from 32 °F to 130 °F. Each cylinder is equipped with a suitable back pressure valve. The cylinders are manufactured, tested, and stamped in accordance with DOT 4BW500 or DOT 4BA500. The systems are designed for Total Flooding Protection against Class A, Class B and Class C fires occurring within an enclosure.
Chemori Pre-Engineered Unit is a clean agent system of the Chemori 125 pre-set quantities. It has specific flow rates in the set of pipes, fittings, and nozzles for various hazards. Specifically, they are limited to the types and sizes by Underwriters Laboratories based on the actual fire test conducted. Chemori provides the Pre-Engineered Units ranging from 3 lb, 6 lb, 12 lb, and 18 lb that are super-pressurized to 240 psig at 70 °F. The larger models are 35 lb, 70 lb, 140 lb, 240 lb, 360 lb and 520 lb in which the units are super-pressurized to 360 psig at 70 °F. Each cylinder is equipped with a suitable cylinder valve. All these units are designed for Total Flooding Protection against Class A, Class B and Class C fires occurring within an enclosure.
