Ansul Piranha PRX 1.5 Gallon - 430182

The Ansul 430182 is a pre-filled 1.5-gallon container of PRX wet chemical agent, compatible with ANSUL Piranha kitchen fire suppression systems and UL-listed for Class K fire suppression. PRX is ANSUL's proprietary potassium-based wet chemical formulation that suppresses cooking oil and grease fires through saponification, where the agent reacts with hot cooking oil to form a foam layer that seals the fuel surface, and through rapid surface cooling that brings the oil temperature below its re-ignition point. The 430182 pre-filled container format simplifies the Piranha system recharge process by providing the exact agent volume needed for 1.5-gallon cylinder configurations.

The Piranha system is ANSUL's wet chemical kitchen fire suppression platform for commercial kitchens, using the same PRX agent chemistry as the R-102 system but in configurations optimized for specific high-hazard cooking equipment. The 1.5-gallon 430182 container size corresponds to smaller Piranha system cylinder configurations, so always verify the correct agent volume for your specific Piranha system design before recharging. Using an incorrect volume, even with the correct PRX agent, can alter the system's hydraulic discharge performance and potentially violate the UL 300 listing for the protected appliance configuration.

ANSUL Piranha and R-102 systems under NFPA 17A require PRX agent replacement after every system discharge. Semiannual professional service by a certified distributor is also required, during which the agent tank and all components are inspected. After discharging the existing agent and internally inspecting the cylinder, fill with the 430182 PRX to the volume specified in the Piranha system design documentation, rebuild the valve with the appropriate ANSUL valve rebuild kit, repressurize with nitrogen, and leak-test before returning to service. Available through authorized ANSUL distributors. Store away from freezing temperatures, as PRX agent can crystallize when frozen.

Replace the PRX agent charge using the 430182 container after every Piranha system discharge and at the 6-year internal examination per NFPA 17A. Flush distribution piping per the ANSUL Piranha service documentation before refilling. Do not recharge without flushing residual discharged agent from the piping. Verify the correct fill volume for your specific cylinder configuration using the Piranha system design documentation. Never mix PRX with other wet chemical agents, as incompatible agents can form precipitates that clog nozzles and distribution piping. Document the recharge in the fire suppression system inspection record and apply a new service label to the cylinder.

Is the 430182 the same as the R-102 PRX 5-gallon (423320)?

Both are ANSUL PRX wet chemical agent, the same formula in different container volumes. The 430182 provides 1.5 gallons for smaller Piranha cylinder configurations, while the 423320 provides 5 gallons for larger R-102 configurations. The agent chemistry is the same; the container size is selected to match the specific cylinder fill volume. Always use the container size that matches your cylinder's required fill volume without overfilling or underfilling.

Can the 430182 be used in Range Guard systems?

No. Range Guard systems are listed with Karbaloy wet chemical agent. ANSUL PRX and Karbaloy are different wet chemical formulations with different UL 300 listings. Using PRX in a Range Guard system voids its UL 300 listing. Always match the agent to the system manufacturer: PRX for ANSUL R-102 and Piranha, Karbaloy for Range Guard.
