Range Guard 2.5 Gallon Karbaloy 120031

The Range Guard 120031 is a pre-filled 2.5-gallon container of Karbaloy wet chemical agent for Range Guard Class K kitchen fire suppression systems. Karbaloy is the proprietary Range Guard wet chemical formulation — a potassium-based agent engineered to suppress high-temperature cooking oil and grease fires through a combination of rapid cooling and saponification. When discharged, Karbaloy reacts with hot cooking oils to form a soapy foam blanket that seals the fuel surface and prevents re-ignition — the defining suppression mechanism of all class k wet chemical fire extinguisher systems.

The 2.5-gallon 120031 is a smaller-capacity complement to the 6-gallon RG-6G Karbaloy recharge (87-120033-001), designed for Range Guard systems using 2.5-gallon cylinder configurations. Like all Range Guard Karbaloy agent products, the 120031 is the only OEM-approved agent for Range Guard systems — substituting a different wet chemical agent alters the system's hydraulic discharge characteristics and voids the UL 300 listing. The range guard fire suppression system manual specifies Karbaloy as the required agent for all RG-series cylinder models.

For fire protection contractors servicing Range Guard kitchen fire suppression system components, the 120031 is a mandatory recharge item for 2.5-gallon Range Guard cylinder configurations after any system discharge or during the 6-year internal examination per NFPA 17A. Authorized range guard distributors stock the full Karbaloy product line — including the 120031 (2.5-gallon) and 87-120033-001 (6-gallon) — ensuring the correct agent volume is available for any Range Guard system configuration in the field.

Post-Discharge Recharge

After any Range Guard system discharge, the cylinder must be fully serviced before recharging with fresh 120031 Karbaloy agent. This includes flushing the system piping per the range guard service manual, replacing all nozzle caps, and rebuilding the discharge valve before introducing the new agent charge. Do not partially recharge — the Range Guard system is designed for a specific total agent volume per the range guard fire suppression system manual and UL 300 listing.

6-Year Internal Examination

During the mandatory 6-year internal examination per NFPA 17A, the existing Karbaloy charge must be discarded and replaced with fresh 120031 regardless of apparent condition. Wet chemical agents can degrade in high-temperature kitchen environments over multi-year service intervals. Fresh agent ensures the potassium lactate fire extinguisher chemistry remains effective at the rated concentration. Document the agent replacement on the fire suppression system inspection record.

Storage

Store the 120031 in a cool, dry location away from freezing temperatures. Karbaloy's potassium-based chemistry can crystallize below freezing, potentially causing nozzle blockage during discharge. Inspect stored containers for crystallization before use if they have been exposed to sub-freezing conditions.

Can I use Amerex or Pyro-Chem wet chemical agent instead of Karbaloy?

No. The Range Guard system is UL 300 listed specifically with Karbaloy agent. Using a different wet chemical agent — including class k wet chemical fire extinguisher agents from other manufacturers — voids the UL 300 listing. The range guard nozzle chart pdf and range guard kitchen system manual confirm Karbaloy as the only approved agent. Always use OEM agent sourced through authorized range guard distributors.

Is Karbaloy the same formulation as potassium acetate fire extinguisher agents?

Karbaloy is Range Guard's proprietary wet chemical formulation based on potassium chemistry. While other class k wet chemical fire extinguisher agents are also potassium-based — including potassium acetate fire extinguisher and potassium bicarbonate fire extinguisher formulations — each manufacturer's proprietary blend has specific viscosity, concentration, and flow characteristics matched to their system's hydraulic design. Karbaloy's specific properties are calibrated for Range Guard nozzle flow rates and discharge geometry.
