CommanderEDGE | 9 Litre Water Pre-filled Low Freeze Additive Fire Extinguisher

FAQs

Why choose a 9 litre low freeze additive extinguisher over a 6 litre model?

The 9 litre model offers a superior 21A fire rating compared to the 13A rating of 6 litre units, providing enhanced fire-fighting capability for tackling larger Class A fires. The increased capacity delivers extended discharge time, allowing operators more time to effectively extinguish fires, and provides greater coverage area, making it ideal for larger outdoor spaces, commercial premises, warehouses and industrial environments where more substantial fire protection is required.

What temperature can this extinguisher withstand?

The Commander 9 litre water fire extinguisher with low freeze additive can operate reliably in temperatures ranging from -10°C to +60°C. The 13% anti-freeze water additive prevents the extinguishing medium from freezing, maintaining it in a fluid state even in sub-zero conditions, ensuring the extinguisher remains fully functional when needed most during cold weather emergencies.

What types of fires is this extinguisher suitable for?

This extinguisher is rated 21A and designed specifically for Class A fires involving solid combustible materials such as wood, paper, textiles and other carbonaceous substances. It should not be used on Class B fires involving flammable liquids, Class C fires involving flammable gases, Class D fires involving combustible metals, Class F fires involving cooking oils and fats, or on electrical equipment fires.

What does the 21A fire rating mean?

The 21A fire rating indicates this extinguisher has been tested and certified to extinguish a Class A test fire consisting of a wooden crib measuring 2.1 metres in length. The higher the number, the larger the fire the extinguisher can tackle. A 21A rating provides significantly more fire-fighting capability than a 13A rating, making the 9 litre model more effective for larger fires and commercial applications.

Where are 9 litre low freeze additive extinguishers most commonly used?

The 9 litre capacity makes this extinguisher ideal for larger outdoor areas and commercial premises including warehouses and distribution centres, industrial facilities and manufacturing plants, petrol stations and service areas, holiday parks and caravan sites, cold storage facilities, outdoor car parks and loading bays, construction sites, agricultural buildings and farm premises, and any large unheated spaces exposed to freezing temperatures where enhanced fire protection is required.

How does the low freeze additive affect fire-fighting performance?

The low freeze additive does not negatively impact fire-fighting performance. The extinguisher works in exactly the same way as a standard water extinguisher, cooling burning materials and preventing re-ignition. The additive simply lowers the freezing point of the water from 0°C to -10°C, ensuring the extinguisher remains operational in cold conditions. The fire suppression effectiveness, discharge characteristics and environmental credentials remain unchanged.

What is the advantage of pre-filled low freeze additive extinguishers?

CheckFire is the only UK supplier offering pre-filled low freeze additive extinguishers, which arrive ready for immediate installation without any on-site preparation. This eliminates the need for customers or installers to mix anti-freeze additives themselves, saving time, reducing the risk of incorrect mixing ratios, ensuring consistent quality and performance, and providing ultimate convenience and peace of mind that the extinguisher is properly prepared for winter conditions.

What servicing does this extinguisher require?

The 9 litre low freeze additive extinguisher requires the same annual servicing as all fire extinguishers, conducted by a qualified technician in accordance with BS 5306 standards. The service includes checking the pressure gauge, inspecting the cylinder for damage or corrosion, examining seals and components, verifying the unit is fully charged, and confirming the low freeze additive is still effective. Extended servicing every five years involves internal inspection of the cylinder and valve mechanism to ensure continued reliability in harsh outdoor conditions.
