Amerex C270 1.75 Gallon (Stainless Steel, Black) Water Mist Fire Extinguisher - 27699

The Amerex C270 is a specialized, high-performance fire extinguisher engineered for environments where collateral damage from traditional agents is unacceptable. In modern MRI suites, pharmaceutical clean rooms, and high-end corporate data centers, the residue from a multipurpose unit can be as financially devastating as the fire itself. The Amerex C270 solves this by utilizing de-ionized water and a specialized sonic misting nozzle to create a non-conductive, non-contaminating discharge.

Rated 2-A:C, this 1.75-gallon unit provides elite Class A cooling power while maintaining a safe dielectric barrier for energized electrical equipment. The C270 features a black powder-coated stainless steel cylinder, offering a sophisticated, low-profile aesthetic for high-end architectural spaces without compromising on industrial-grade safety.

The Science of Mist: De-ionization and Aerosolized Cooling

1. Dielectric Breakdown Prevention

Standard water contains minerals and ions that conduct electricity. Amerex utilizes de-ionized water, which has been processed through ion-exchange resins to remove conductive impurities. When discharged through the precision-machined misting nozzle, the water is broken into droplets smaller than 100 microns. These micro-droplets create a high-resistance path, preventing electrical current from traveling back up the stream.

2. Aerosolized Endothermic Cooling

The misting nozzle maximizes the surface-area-to-volume ratio of the water. As the mist enters the flame zone, it provides near-instantaneous flash cooling by absorbing massive amounts of thermal energy. Simultaneously, the ultra-fine mist penetrates deep into porous Class A materials to prevent re-ignition without the splatter effect common with traditional water streams.

3. Non-Magnetic and MRI Readiness

In high-field magnetic environments such as MRI suites, any ferromagnetic material becomes a dangerous projectile. The C270 is manufactured with non-magnetic components, ensuring the unit remains inert and safe to store in the vicinity of powerful medical magnets.

Why the Amerex C270 is the Choice for Facility Managers

• Zero-Residue Recovery: Following a discharge, there is no powder to vacuum and no corrosive film to remediate. The de-ionized water simply evaporates, allowing sterile medical environments and clean rooms to return to service in hours rather than days.
• Respiratory and Visibility Safety: Dry chemical agents create a white-out condition that can cause respiratory distress. The water mist discharge remains breathable and translucent, allowing medical staff to maintain visual contact with patients.
• Industrial Longevity in a Premium Finish: The cylinder is constructed from high-grade stainless steel with a sleek black finish that resists hospital-grade disinfectants while blending into modern interior designs.

The Amerex C270 is the primary specified choice for zero-contamination hazard zones where non-toxic fire suppression is a priority:

• Hospitals and Patient Care Areas: Providing Class A protection near sensitive monitoring equipment.
• MRI and Imaging Centers: Safe for use in high-field magnetic environments as part of an MRI safety protocol.
• Pharmaceutical Clean Rooms: Essential for environments where particulate count is strictly regulated.
• Corporate Data Centers: An excellent alternative to clean agents for protecting server racks where cooling is a priority.
• Museums and Archives: Safeguarding historical artifacts from the chemical staining of a standard fire extinguisher.

To maintain JCAHO fire safety compliance and ensure your medical facility remains insurance-eligible, the C270 must follow a strict maintenance protocol:

• Monthly Visual Inspection: Verify the pressure gauge is in the green zone and the safety pin is secured. Check the misting nozzle for dust or obstructions.
• Annual Professional Service: A technician must conduct an external examination. Only certified de-ionized water must be used for any refill to maintain the Class C rating.
• 5-Year Hydrostatic Test: Mandatory every five years for water-based units to ensure the cylinder remains structurally sound.
• 5-Year Internal Maintenance: Every five years, the de-ionized water must be replaced to prevent mineral buildup from affecting suppression performance.

What is the difference between this and a standard water unit?

Standard units use tap water, which conducts electricity. The Amerex C270 uses de-ionized water and a misting nozzle, making it safe for use near energized electrical equipment.

Is it safe for a 3-Tesla MRI room?

Yes. Since this unit is built with non-magnetic materials, it is a standard safety choice for MRI suites where traditional steel units would be a magnetic projectile hazard.

How do I use the PASS method with this unit?

Pull, Aim, Squeeze, and Sweep. Because the mist is fine, you can stand closer to the fire than with a high-pressure dry chemical unit.
