CO2 Gas Cartridge

Available Models: KEW 40, KEW 60, KEW 120, KEW 200 & KEW 300

CO2 Gas Cartridge

The CO2 Gas Cartridge from Krunal Engineering Works is a high-performance propulsion component designed for industrial-grade cartridge-type fire extinguishers. Manufactured using premium seamless or ERW steel tubes with a hot-spun fabrication process, these cartridges are engineered to withstand extreme internal pressures. Each unit features a precision-machined brass nut to ensure a leak-proof seal and a secure fit, providing total reliability when it is needed most.

To ensure long-term durability in tough environments, every cartridge is treated with a protective metal primer followed by two coats of epoxy steel-gray paint, making it highly resistant to corrosion and wear. These gas cartridges are the power source behind rapid fire suppression, delivering consistent pressure to discharge dry chemical powders or water-based agents instantly upon activation. They offer the flexibility required to power various extinguisher sizes. Whether used in industrial plants, marine environments, or high-risk chemical zones, these cartridges provide a dependable, self-contained energy source that functions perfectly even in the absence of external power.

Frequently asked questions.

How does a CO2 gas cartridge work during a fire?

When the fire extinguisher’s plunger is struck, a sharp internal pin pierces the diaphragm of the CO2 cartridge. The compressed gas instantly expands into the main cylinder, creating the pressure required to push the extinguishing agent (powder or water) out through the discharge hose.

A machined brass nut provides a high-precision thread that ensures a perfectly airtight seal. This is critical because any small leak at the threading would result in a failure to pressurize the extinguisher during an emergency.

Yes. Since the gas is contained in a heavy-duty seamless steel tube, these cartridges are designed to remain stable and functional across a wide temperature range, making them ideal for both outdoor industrial sites and indoor facilities.

No. These cartridges use specific thread sizes, such as 268mm x 1.27 Pitch or 18.6mm x 1.81 Pitch, to match the head assembly of the extinguisher. It is important to use the correct model (like KEW 60 or KEW 120) to ensure a proper fit.
