Amerex Model-240H Special Fire Extinguisher

Amerex Model-240H Special Fire Extinguisher for use in Manned Pressure Vessels is designed for the pressures and confines of a hyperbaric chamber. The Model-240 comes with a fill adaptor and has been fully tested and approved for use in all U.S. Navy standard double lock chambers.

In actual operation, the Amerex Model-240H Hyperbaric Water Based Fire Extinguisher is filled with potable water and then pressurized to 200 psig. The unit comes complete with a fill valve, pressure gauge and two safety valves to prevent over and under pressurization. The Model-240H can be used in a chamber pressurized to a maximum depth of 225 FSW. If the unit is activated at the maximum depth, and held until the water is exhausted, the pressure inside the extinguisher will equal the chamber pressure. With the chamber and extinguisher at equilibrium, the fire extinguisher cannot implode or crush.

Application:

• Designed for use in manned pressure vessels/ hyperbaric chambers.
