Stored Pressure Fire Extinguishers
Stored Pressure

Most common type of fire extinguishers and can be recognized with the presence of a pressure gauge.

Contact for Service
Stored pressure fire extinguishers are composed of the agent and a propellant which is typically nitrogen or compressed air to act as the propellant.

These units, since they’re under pressure, require hydrostatic testing and internal examination at regular intervals. Agents for store pressure fire extinguishers include water, foaming and other wet agents, dry chemical powder, Halogenated streaming agents like Halon 1211, FE-36, and Halotron.

Cartridge-Operated Fire Extinguishers

Extinguishing agent – typically CO2 or Nitrogen – is typically stored in a separate cartridge that is punctured just before operating the type of extinguisher.

The advantage of cartridge-operated fire extinguishers carry is they can discharge the fire agent at greater distances than the stored pressure extinguishers. These are favored by professionals at utilities facilities and petrochemical plants.

Cartridge-Operated fire extinguishers are required to have a hydrostatic test performed every 12 years. These extinguishers come these kinds of agents: ABC, BC, and Purple K dry chemical powders, as well as some class D agents for metal fires.

Self-Expelling Fire Extinguishers

This extinguisher uses CO2 as the source of pressure to expel the extinguishing agent. Hydrostatic testing is required every 5 years.

Contact for Service

Where other extinguishers require nitrogen as a propellant, these extinguishers use the natural high-pressure of CO2 to quickly flash to a vapor when expelled.

Self-Expelling fire extinguishers are best used in indoor situations where sensitive equipment or other items require a clean extinguishing agent (no residue) from liquid or electrical fire hazards.

Stored Pressure Fire Extinguishers

Best suited for large capacity fires in facilities like airports, helipads, parking facilities, and construction sites where more agent capacity is needed.

Wheeled fire extinguishers are not as mobile as their hand-held counterparts but can accommodate a larger scale fire hazard. They come in cartridge-operated and stored pressure options with a capacity of 50lbs to 350lbs of agent.

These extinguishers use the following agents: ABC, BC, and Purple K dry chemical powders, Halogenated agents, foams, and class D agents for metal fires.
