The Higher Capacity Trolley Mounted Fire Extinguisher from Krunal Engineering Works is a heavy-duty, high-performance safety solution designed for large-scale industrial and commercial fire hazards. Built with a robust mild steel body and engineered as per the IS 16018 standard, these extinguishers provide maximum durability and reliable operation in high-risk environments where portable units are insufficient. Mounted on a specialized trolley for easy maneuverability, these units are available in both Constant Pressure and Cartridge types, offering the versatility and power required to suppress large-scale fires effectively.
Using high-grade dry chemical powder (as per IS: 14609 / IS: 4308) along with Nitrogen or CO₂ propellants, these units ensure a powerful and consistent discharge. With a hydraulic test pressure of 35 kgf/cm² and a service pressure of 15 kgf/cm², the system is built to withstand extreme conditions while maintaining peak performance. These extinguishers offer an impressive discharge range of 3 meters and a minimum effective discharge efficiency of 85%. This makes them an essential safety asset for warehouses, industrial plants, and fuel storage areas where high-capacity fire protection is critical.

The steel cylinder typically lasts 10 to 15 years. However, the internal dry powder should be serviced or replaced every 3 years to ensure it remains free-flowing and ready for a large-scale emergency.
Yes. Despite the large weight (up to 75 kg), the unit is built on a balanced, heavy-duty trolley. This ergonomic design allows a single operator to quickly roll and maneuver the extinguisher across industrial floors or yards.
You should use a trolley-mounted unit when protecting high-risk areas like warehouses, fuel depots, or large factories. These units provide a much longer discharge time and greater volume of media than portable versions, which is critical for suppressing larger fires.
Yes. Because these units use specialized ABC or BC dry chemical powder, they are non-conductive. This makes them safe for use on high-voltage electrical equipment, machinery, and transformers.
