120032 4 GALLON KARBALOY WET CHEMICAL RECHARGE

The Badger / Range Guard 4 Gallon Karbaloy Wet Chemical Recharge (87-120032-001) is a high-performance extinguishing agent engineered specifically for the Range Guard Kitchen Fire Suppression System. In the intense environment of a commercial kitchen, grease fires present a unique challenge: they burn at extremely high temperatures and are prone to violent re-ignition. Karbaloy is a precision-blended potassium carbonate-based solution designed to meet these challenges by providing an immediate chemical knockdown and a long-lasting thermal barrier.

This 4-gallon refill is the factory-specified agent for the RG-4GS (Standard) and RG-4GM (Manifold) cylinder assemblies. As a pre-mixed, stored-pressure agent, it is designed for rapid atomization through the system's discharge nozzles. For fire protection contractors, the 87-120032-001 is the mandatory choice for restoring a system to its UL 300 and NFPA 17A listed configuration after a discharge or during mandatory 6-year internal maintenance.

The Saponification Reaction

When Karbaloy is discharged onto hot, burning grease, it initiates saponification. The highly alkaline potassium carbonate reacts with the free fatty acids in the cooking oil to create a thick, soapy foam blanket that excludes oxygen, suppresses flammable vapors, and creates a physical barrier preventing fire migration.

High-Mass Thermal Quenching

Unlike dry chemical agents that only interrupt the chemical chain reaction, Karbaloy is a liquid agent with significant thermal mass. As it strikes the superheated oil, it absorbs massive amounts of heat through evaporation, rapidly cooling the oil below its auto-ignition point and ensuring the fire cannot re-flash.

pH Stability and Foam Longevity

The Karbaloy formula is engineered to maintain a pH level above 11. This high alkalinity ensures that the saponified foam remains stable even under the extreme radiant heat of the kitchen hood, providing the difference between successful suppression and catastrophic re-ignition.

Factory Pre-Mixed Accuracy

Field-mixing fire chemicals is a leading cause of system failure. Karbaloy is supplied in a pre-mixed 4-gallon container, ensuring the specific gravity and chemical concentration meet UL 300 testing protocols, eliminating human error and ensuring the system performs at full efficiency.

Compliance with NFPA 17A Maintenance Cycles

NFPA 17A requires a full internal inspection and agent replacement every 6 years for stored-pressure wet chemical systems. Using the genuine 87-120032-001 refill ensures the cylinder remains free of internal corrosion and that the agent has not settled, maintaining the facility's insurance standing.

Low-Temperature Resilience

Karbaloy is rated for use in environments as low as -40°F. This makes it an ideal solution for unheated storage areas or stadium concessions where standard water-based agents would freeze and rupture the piping.

• Commercial Deep-Fat Fryers: Providing the aggressive cooling and foam-blanketing required for high-volume oil hazards.
• Heavy-Duty Griddles: Ensuring full-surface coverage and vapor suppression for large-scale cooking lines.
• Institutional Kitchens: Maintaining a code-compliant environment in hospital and school cafeterias where fire safety is a matter of public record.
• High-Volume Franchise Lines: Standardizing fire protection across multiple locations to simplify parts procurement and maintenance.
• Industrial Food Processing: Protecting large-scale industrial fryers where Class K hazards are present in bulk.

Total System Flush Protocol

Before refilling with new Karbaloy, the technician must thoroughly flush the cylinder and discharge piping with clean water. Any residual old agent can contaminate the new solution and lead to nozzle blockages.

Nitrogen Pressurization Audit

After the 4 gallons are added, the cylinder must be pressurized with high-purity nitrogen to the factory-specified operating pressure (typically 175 PSI). The gauge must be checked for a dead-center green zone reading.

Nozzle Orifice Inspection

Because Karbaloy is a high-pH, salt-based solution, inspect nozzles for crystallized salt deposits. If found, nozzles must be cleaned to ensure a perfect spray pattern.

Cleanup Protocol

In the event of a discharge, Karbaloy should be cleaned immediately using warm, soapy water. While non-toxic, its high alkalinity can cause chemical pitting on aluminum if left to dry.

Can I use Karbaloy in an Ansul R-102 system?

No. While both are wet chemical agents, they have different specific gravities and flow characteristics. Using Karbaloy in a non-Range Guard system violates the UL 300 listing and could result in system failure. Always use the manufacturer-specified extinguishing agent.

Why does the agent need to be replaced every 6 years?

Over time, wet chemicals can undergo minor chemical shifts. More importantly, NFPA mandates the 6-year internal inspection to check the cylinder for corrosion. Fresh agent ensures the system remains at full potency.

Is Karbaloy hazardous to staff?

Karbaloy is a potassium carbonate solution and is considered a mild skin irritant due to its high pH. It is non-toxic but staff should wear gloves during post-discharge cleanup to avoid irritation from the highly alkaline residue.
