Amerex Wet Chemical for KP2.75 16924 - OEM

The Amerex 16924 is the OEM wet chemical agent refill for Amerex KP2.75 kitchen fire suppression systems. In plain terms: this is the fire-fighting chemical that goes inside the suppression cylinder. When a grease fire breaks out on the protected cooking equipment, the system sprays this agent onto the burning oil or grease — it reacts chemically with the hot fat to form a soapy foam layer that smothers the fire and prevents it from reigniting. It's formulated specifically for Class K fires, which is the fire code category for commercial cooking oil and grease fires.

After a KP2.75 system discharges — whether from an actual fire or an accidental trip — the cylinder must be professionally refilled with fresh 16924 wet chemical agent before the system is back in service and protecting your kitchen. This refill must be done by a licensed fire suppression service technician, not a DIY job. The agent also gets replaced during the required 6-year internal inspection even if the system hasn't fired, because wet chemical agents can degrade over time in the heat of a commercial kitchen. Using anything other than the OEM 16924 agent voids the system's UL listing — which means your system may no longer meet the fire code requirements that your insurance and health department rely on.

The KP2.75 is a smaller Amerex kitchen suppression cylinder used in compact commercial kitchen configurations — single-appliance setups, food trucks, or satellite cooking stations. The 16924 refill is sized for the 2.75-gallon cylinder capacity. Available through authorized Amerex distributors. Always have your service technician verify the KP2.75 cylinder model before ordering to confirm 16924 is the correct agent for your specific system design.

After Any System Discharge

Whether the system fired from a real fire or was accidentally tripped, the cylinder must be completely emptied, inspected internally, and refilled with fresh 16924 agent before being returned to service. A partially discharged cylinder cannot simply be "topped off" — NFPA 10 and NFPA 17A require a complete recharge. Your kitchen cannot be considered fully protected until this is done. Call a licensed fire suppression technician as soon as possible after any discharge event.

Every Six Years — Even Without a Discharge

At the 6-year internal examination required by NFPA 17A, the agent charge is replaced regardless of condition. Wet chemical agents can break down over time in the temperature fluctuations of a commercial kitchen environment. Your semi-annual inspection technician tracks this timeline and will schedule the 6-year service when it's due.

Can I use ANSUL PRX or Range Guard Karbaloy in my Amerex KP2.75 system?

No. Each brand's kitchen suppression system is tested and certified with its own specific wet chemical agent formula. Using a different brand's agent in an Amerex KP2.75 system voids the UL 300 listing, which means your system may no longer legally satisfy fire code requirements. Always use the Amerex OEM 16924 agent, sourced through authorized Amerex distributors.

How do I know if my system uses the KP2.75 cylinder?

The cylinder model is printed on a label on the cylinder itself. Your fire suppression service technician can also identify it during your next semi-annual inspection. The Amerex KP system comes in several cylinder sizes — KP2.75, KP250, KP375, and KP475 — and each uses a specific agent refill. Using the wrong volume can affect how the system performs and may not meet the coverage requirements for your protected cooking equipment.
