FAQ
Q1: Compared with the common 25mm hoses on the market, what are the specific advantages of this 33mm diameter hose?
A: This is not merely an increase in diameter, but a qualitative leap in fire-fighting efficiency. The 33mm large diameter means that the water output increases by approximately 70%. Under the same water pressure, it can instantly spray out a larger volume of water column to quickly suppress the fire. For an initial fire, these precious few seconds might be the dividing line between "control" and "loss of control". It is particularly suitable for places where Class A solid combustibles exist (such as stored goods, wood, and textiles), providing more thorough fire suppression and preventing re-ignition.
Q2: The warehouse area is quite large. Is a length of 30 meters sufficient? Is customization required?
A: 30 meters is our standard golden length. After calculation, it is sufficient to cover any fire point within a standard fire compartment.
- If the column spacing is large and there are dead corners: We offer customized extensions of 40 meters or 50 meters to ensure "no dead corners" protection.
- If the layout is compact and only key areas need to be covered: We also offer an economical option of 20 meters to save you costs and space.
Q3: How to choose between copper nozzles and engineering plastic nozzles?
A: It depends on your usage frequency and budget considerations.
- Choose copper nozzles: If you are pursuing ultimate durability and all-condition applicability. It is corrosion-resistant and impact-resistant, with a lifespan consistent with that of the main body of the reel. It has almost no replacement cost and is suitable for heavy industrial scenarios with frequent use and complex environments.
- When choosing engineering plastic nozzles: If you are pursuing lightweight, high cost performance and anti-freezing hands. It is about 40% lighter in weight, easier to operate, and does not cause cold hands in extremely cold environments. It has good insulation performance and an extremely high cost performance, making it suitable for daily maintenance scenarios such as commercial complexes and office buildings.
Key point: The spray performance of both nozzles meets the standards. You can flexibly configure them according to your actual operational needs.
