Water Tank Trailer Modular tanks designed for large-scale liquid transportation, the tanks are made of food-grade polyethylene or 304 stainless steel, with internal honeycomb anti-wave plate structure to effectively reduce the risk of liquid shaking. The surface is sandblasted and UV coated to withstand extreme environments ranging from -30℃ to 80℃. The unique multi-functional interface system supports three discharge modes: gravity self-flow, pressure pumping and fire-fighting water cannon, which is suitable for agricultural irrigation, municipal landscaping and emergency water supply in disasters. Some models are equipped with self-cleaning filtration device and can be directly loaded with drinking water, which meets WHO water quality safety standards and is widely used in remote mining areas and field logistics.
