671 Amerex DeIonized Water 2.2 Gallons, OEM, 16363

The Amerex 671 Deionized Water Recharge Agent (Part #163632) is the specialized OEM solution required for maintaining high-performance water mist fire extinguishers. Unlike standard tap water, this 2.2-gallon recharge agent undergoes a rigorous deionization process to remove minerals and impurities that could conduct electricity or corrode the internal components of high-end fire protection equipment.

This agent is specifically engineered for use in environments where clean suppression is non-negotiable. When discharged through a water mist nozzle, this deionized water creates a microscopic fog that cools the fire and displaces oxygen without leaving behind the messy residue associated with dry chemical agents or the conductive risks of standard water. For facility managers, the Amerex 671 is the definitive choice for protecting high-value assets in sterile and electronically sensitive zones.

Dielectric Integrity

Standard water contains ions from salt and minerals that allow electricity to flow through it. The deionization process removes these ions, giving the Amerex 671 high dielectric strength. This makes it safe for use near energized electrical equipment, meeting strict Class C fire safety requirements without the risk of technician electrocution.

Microscopic Fog Cooling

When the 163632 agent is forced through a specialized nozzle, it atomizes into droplets smaller than 100 microns. This increases the surface area of the water exponentially, allowing for rapid heat absorption and evaporation, which chokes the fire by removing thermal energy and displacing oxygen.

Zero-Corrosion Purity

Because the minerals are removed, the agent is non-corrosive. This is critical for the longevity of the extinguisher's internal liner and the protection of the sensitive electronics it is designed to safeguard, preventing the pitting associated with standard water-based suppression.

MRI Safety Compliance

The Amerex 671 is the mandatory agent for the C272NM (Non-Magnetic) series. In the high-magnetic fields of an MRI suite, using the correct purified agent is vital for maintaining MRI-safe fire protection standards.

Sterile Environment Maintenance

In surgical centers and clean rooms, post-fire cleanup can be more expensive than the fire itself. This agent leaves zero residue, allowing for a rapid return to service without the need for extensive chemical decontamination.

Environmental and Occupational Health

As a chemical-free agent, the 671 is among the most eco-friendly fire suppressants available. It poses no respiratory risk to patients or staff, making it well-suited for healthcare fire safety environments.

• MRI & Imaging Suites: Providing a non-magnetic, non-conductive solution for diagnostic imaging fire safety.
• Data Centers & Server Rooms: Suppressing common combustibles (Class A) near sensitive servers without the collateral damage of dry chemicals.
• Telecommunications Hubs: Protecting critical switching infrastructure where non-conductive suppression is a mandatory requirement.
• Surgical Centers & Labs: Maintaining a sterile environment during sensitive medical procedures or chemical research.
• Historical Archives & Museums: Protecting rare documents and artifacts from fire without the staining or corrosive effects of standard water.

Professional Recharge Only

Fire extinguishers are pressure vessels. Recharging must be performed by a certified fire technician using a pressurized nitrogen source and a calibrated scale to ensure the correct agent-to-air ullage.

Purity Verification

Never dilute the Amerex 671 with tap water. Even a small amount of hard water can compromise the electrical conductivity of the agent, creating a safety hazard for the operator.

Hydrostatic Testing Integration

When an extinguisher reaches its 5-year hydrostatic test interval, the agent must be replaced. Using a fresh pail of 163632 ensures the internal components remain free of mineral scale.

Nozzle Inspection

During the recharge, the technician must verify the water mist nozzle is free of debris. The high purity of the 671 agent is designed to prevent orifice clogs, but external dust should be cleared.

Why can't I just use distilled water from a grocery store?

Grocery store distilled water is not tested or verified for the specific dielectric strength required for fire suppression. Using non-OEM water can void the extinguisher warranty and creates a significant professional liability if used on an electrical fire.

How many extinguishers will one 2.2-gallon pail fill?

Most Amerex water mist models (B272/C272) have a 2.5-gallon capacity. This 2.2-gallon pail provides the exact amount of agent required to leave the necessary ullage (air space) for proper pressurization at 100 PSI.

Is this agent effective on grease fires?

No. Water mist extinguishers are for Class A and C fires. They should never be used on Class K grease fires, as water can cause a violent reaction with hot oil. Always use a wet chemical extinguisher for kitchen hazards.
