Amerex C272NM - OEM

The Amerex C272NM is a professional-grade, 2.5-gallon water mist fire extinguisher designed specifically for environments where traditional extinguishing agents would cause as much damage as the fire itself. By utilizing a specialized misting nozzle and de-ionized water, the C272NM provides a powerful 2-A:C fire rating for ordinary combustibles while remaining safe for use on energized electrical equipment.

Unlike dry chemical extinguishers that leave a corrosive, cloud-like residue, the Amerex water mist system utilizes an ultra-fine spray that evaporates quickly and leaves no chemical footprint. The "NM" designation stands for Non-Magnetic — this unit is constructed with specialized materials that make it MR-Conditional, safe for use in and around MRI suites and other high-magnetic-field medical environments.

The Science of De-Ionized Water Mist

The primary driver for the C272NM's effectiveness is the combination of water purity and nozzle engineering.

• The De-Ionization Factor: Standard tap water contains minerals and ions that conduct electricity. The C272NM uses de-ionized water, which has had these minerals removed, making the water non-conductive. This allows the operator to safely suppress fires in energized electrical cabinets or medical devices without the risk of electrical shock.
• The Misting Nozzle: Traditional water extinguishers stream water, which can splash burning fuel. The Amerex misting nozzle breaks the water into billions of microscopic droplets, creating a massive surface area for rapid heat absorption and steam cooling that smothers the fire's oxygen supply without scattering burning debris.
• Respiratory Safety: Because the agent is simply purified water, it is non-toxic and does not create the breathing difficulties associated with dry chemical powder or the oxygen displacement of CO2.

The Amerex Advantage: Engineered for Critical Spaces

• Non-Magnetic Construction: The cylinder and valve components are manufactured from materials that are not attracted to magnets. This is a life-safety requirement for MRI rooms, where a standard steel extinguisher would be pulled into the machine with lethal force.
• Polished Stainless Steel Cylinder: The high-gloss, corrosion-resistant stainless steel body is ideal for clean room environments and hospitals where sterile conditions must be maintained.
• Ease of Service: The C272NM is fully rechargeable and can be serviced by any certified fire protection professional using de-ionized water and a standard nitrogen charge.
• No Residue Cleanup: In a data center or laboratory, dry chemical dust can destroy millions of dollars in equipment. The C272NM minimizes post-fire downtime because there is no powder to vacuum or corrosive residue to scrub.

The Amerex C272NM is the primary specified protection for facilities where clean suppression is a priority:

• MRI Suites and Imaging Centers: The only safe choice for rooms containing high-powered magnets.
• Hospitals and Patient Care: Eliminates the risk of patient respiratory distress caused by dry chemical discharge in confined hallways.
• Data Centers and Server Rooms: Provides a supplemental cooling agent for Class A fires involving cables and partitions without damaging delicate circuitry.
• Laboratories and Pharmaceutical Manufacturing: Maintains sterile environment standards while providing high-performance fire protection.
• Libraries and Archives: The fine mist prevents the soaking damage to paper that a traditional water extinguisher would cause.

The Amerex C272NM is a specialized life-safety asset. To remain compliant with NFPA 10 and Joint Commission (JCAHO) healthcare standards, the following maintenance must be documented:

• Monthly Visual Inspection: Verify the pressure gauge is in the green, the safety pin is present, and the white misting nozzle is free of obstructions.
• Annual Maintenance: A certified fire technician must verify the water level and ensure the de-ionized agent has not been contaminated.
• 5-Year Hydrostatic Test: Because this is a water-based unit, the stainless steel cylinder must undergo a pressure test every five years to verify its structural integrity.
• Professional Recharging: After any use, the unit must be refilled with de-ionized water only. Using tap water will void the C rating and make the unit dangerous for use near electricity.

What does MR-Conditional mean for this extinguisher?

It means the unit has been tested and found to be safe for use in MRI environments up to a specific magnetic field strength. Because it is non-magnetic, it will not be pulled toward the MRI machine, ensuring the safety of the technician and the patient.

Can I use this on a grease fire?

No. Water mist is not rated for Class K kitchen grease fires. While it is safer than a traditional water stream, a specialized Class K extinguisher is required for commercial cooking hazards.

How is this different from a standard water extinguisher?

Standard water extinguishers are conductive and dangerous near electricity. The C272NM carries a C rating due to the de-ionized water and specialized misting nozzle, making it the only water-based extinguisher safe for use on energized electrical equipment.
