Product description:
Heptafluoropropane HFC-227ea (also known as FM200, chemical
molecular formula: CF3CHFCF3) is a colorless, odorless,
non-corrosive, low toxic, non-conductive, high fire extinguishing
efficiency gas, clean and pollution-free, and has no destructive
effect on the atmospheric ozone layer (ozone depletion potential
ODP is zero). At present, heptafluoropropane is considered as an
ideal gas fire extinguishing system to replace alkylogen 1211 and
1301 fire extinguishing systems,It has been widely used in the
world.
Applied range:
Heptafluoropropane fire extinguishing agent can extinguish the following fires | The heptafluoropropane fire extinguisher can't put out the fire of the following substances |
- Electrical fire
- Fire on solid surface
- Liquid fire
- Gas fire that can cut off the gas source before extinguishing the
fire
| - Nitrocellulose, sodium nitrate and other oxidants or chemical
products containing oxidants fire.
- Fire of active metals such as potassium, magnesium, sodium,
titanium, pickaxe and uranium.
- Metal hydride fire such as potassium hydride and sodium hydride
- Fire caused by chemical substances that decompose by themselves,
such as hydrogen peroxide and hydrazine
- Deep fire of combustible solid matter

Working principle and workflow:
When the fire detectors (temperature detectors and smoke detectors)
detect the fire, they will feed back the fire signal to the fire
alarm controller, which will control the audible and visual alarm
and send out an evacuation alarm signal. At the same time, the fire
alarm controller transmits the signal to the gas fire extinguishing
control panel, which controls the linkage equipment. After a delay
of 30 seconds, it sends a start signal (DC24V, 1.5A) to the
electromagnetic driver, which opens the valve for driving the gas
container, drives the gas to open the selection valve in sequence,
and releases the fire extinguishing agent. The fire extinguishing
agent is sprayed into the protected area through the nozzle to
achieve the purpose of fire extinguishing. When the fire
extinguishing agent flows through the pipeline, the signal feedback
device acts and the electric signal is sent back.
