Commercial kitchen grease fires don't respond to ABC or CO2 the way other fires do. ABC powder clumps on hot cooking oil. CO2 cools the surface but lets it flash back once it warms. Buckeye makes a wet chemical Class K agent for exactly this situation. The 6 liter model carries a 1-A:K rating and uses a potassium acetate and potassium citrate blend. It cools the oil, smothers the flame, and leaves a soap layer that prevents re-ignition.
The misting nozzle applies the agent as a fine spray so it doesn't splash burning grease out of the fryer. Stainless steel cylinder, plated brass valve, Schrader recharge valve, wall hook included. Listed to ANSI/UL 8 and ANSI/UL 711.
Plan review often gets this wrong: the portable is UL 711. The pre-engineered hood suppression system over the cookline is UL 300. Two separate listings, two separate products, both required under NFPA 96 anywhere solid fuel or vegetable oil cooking operations exist. Pre-engineered wet chemical systems are governed by NFPA 17A.
Buckeye tested this unit on an 18" by 24" fryer. Common installs are commercial kitchens, restaurants, institutional cafeterias, and food trucks.
