Orient 5112® 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 Orient 5112® 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 Orient Flow Calculation Software version 4.0. Orient Engineered System has various sizes of the Orient 5112® cylinder ranging from 20 lb, 35 lb, 70 lb, 100 lb, 150 lb, 250 lb, 375 lb, 560 lb, and 1200 lb. All cylinders are equipped with a back pressure type valve. A piston in the valve bore is equipped with a rubber seal that keeps the FK-5-1-12 Clean Agent under pressure within the cylinder.
