Why choose our 4kg DCP?

It's not just about firefighting, but also about a safety investment.

When purchasing fire extinguishers, you are not just buying a red canister; you are also buying a "guarantee" in critical moments. For wholesale and engineering procurement customers, we understand that: cost-effectiveness does not mean cutting corners; instead, it means spending money where it matters most.

This 4kg dry powder fire extinguisher is specially designed for scenarios such as factories, warehouses, office buildings, residential projects and vehicle backups. We do not offer one-size-fits-all products. Instead, we provide a fully customized solution from "raw materials to dry powder".

Core Configuration Analysis

【Core Agent】

We have broken the limitation of having only a single ratio in the market. Depending on different protected objects and cost budgets, we offer a variety of options with ABC dry powder contents ranging from 10%, 20%, 40%, 60%, 75% to 90%.
Procurement suggestion: For cost-effectiveness, choose a range of 40% - 60%; for high-standard projects, it is recommended to select a high content range of 75% - 90%, which will result in more rapid fire suppression efficiency.

【Steel Frame Structure】

Tube diameter/height: 130mm * 405mm (Complies with ergonomic holding ratio, takes up no space when stored)
Material and Process: High-quality ST12 low-carbon steel plates are used to ensure the toughness and stamping quality of the cylinder body.
Premium Option: If you need to export to the EU or comply with the CE certification standards, we can upgrade to the DC01 material. This material has more stable performance and a finer surface treatment.

【Stress Resistance Performance】

Work pressure: 14 bar
Test pressure: 25 bar
Pressure vessels must always prioritize safety as the top priority.

【Environmental Adaptability】

Operating temperature: After rigorous testing, the spray performance and internal pressure remain stable in an extremely cold environment of -30℃ to a hot environment of +60℃. Whether it's the outdoor garage in the freezing winter or the open construction site under intense summer sun, it can be ready at any time.

FAQ

Q:Regarding the content of dry powder: Is there a significant difference between 10% and 90%?
A:The main fire-extinguishing component of ABC dry powder is ammonium dihydrogen phosphate. This percentage refers to its content. In a straightforward way: the higher the content, the more efficient the fire-extinguishing, but of course, the cost is also higher.

Here are some purchasing references for you:

10%-20% concentration: Suitable for low-end mass-market or weight-balancing applications. It can pass basic tests, but its effectiveness is limited when it comes to actual firefighting.
40%-60% content: the standard configuration of most engineering projects, to deal with ordinary solid fire and liquid fire completely sufficient
75%-90% content: High-end customization. The fire-extinguishing speed is noticeably fast, the re-ignition probability is low, and it is suitable for demanding orders or high-end projects.

Q: ST12 and DC01 sound similar. Both are made of steel. Why are they classified as two different types? Where is the higher price of DC01 coming from?
A: These two indeed belong to the same family of cold-rolled steel plates, but they have different applications.

ST12: This is a commonly used material in industry. It has a high cost-performance ratio and excellent stamping properties.
DC01: This material is more "delicate", with a higher surface finish and better ductility. Corrosion resistance is slightly better, in humid environment, rust prevention treatment before spraying is easier to do well
