The common portable fire extinguishers in the market are dry powder type, water-based type and foam type. There are few types of gas fire extinguishers, including carbon dioxide. Heptafluoropropane is even less. Today, let's talk about why heptafluoropropane is not suitable for portable fire extinguishers.
Heptafluoropropane, a kind of fire-extinguishing gas, is suitable for total flooding. The environment is generally closed. It can achieve good fire-extinguishing effect by comprehensive coverage and chemical effect as well as physical coverage. If it is semi closed or sprayed unevenly, the fire-extinguishing effect will be greatly reduced, and it is often unable to achieve good fire-extinguishing effect.
The dry powder fire extinguishing is different from the colorless and odorless gas fire extinguishing. The dry powder fire extinguishing relies on chemical particles to cover the flame. In the corresponding small-area primary fire, the effect is extremely prominent. The gas fire extinguishing is usually suitable for dealing with large-area fires, closing the protection area, and then spraying. At this time, the advantage of gas fire extinguishing is highlighted.
Moreover, in terms of price, the price of dry powder is much cheaper than that of gas fire extinguishing agents, and heptafluoropropane is relatively expensive. For all fire-fighting equipment manufacturers, portable fire-extinguishing equipment is more about volume than profit. The price of portable fire-extinguishing equipment is not high, and the profit is relatively low. At the same time, portable fire-extinguishing equipment can not play the effect of gas fire-extinguishing, so, There are very few portable gas fire extinguishers on the market. Dry powder fire extinguishers are affordable, fast to extinguish, and have many resources to purchase, making portable gas fire extinguishers almost absent from the market. Only a few manufacturers will customize portable fire extinguishers for a certain fire extinguishing gas in the case of customization.
