BDF Water Tank

The BDF water tank (Bulk Density Fiber water tank) is a modern composite water tank that uses a structural combination of stainless steel and galvanized steel plates. It typically consists of a top plate, bottom plate, side panels, internal and external supports, sealing rings, flanges, and other components, assembled using bolts.

Its working principle relies on water gravity and internal pressure differences to ensure a consistent water supply. As the water level rises, gravity increases the pressure at the tank's bottom, which automatically pushes water outward through the outlet pipe. When the water level drops, the internal pressure decreases, triggering the inlet to refill the tank, maintaining a stable water level.

This design allows for stable water output and uninterrupted supply, making the BDF water tank ideal for a range of settings, including residential complexes, commercial buildings, and industrial facilities. It is primarily used for storing clean water or domestic-use water, where reliability and durability are critical.

Anti-Corrosion Protection

The BDF water tank features a dual-layer design with stainless steel on the inside and galvanized steel on the outside, offering strong resistance against corrosion. The inner stainless steel contains chromium, which forms a dense chromium oxide film that shields the metal from oxidation. On the outer layer, the galvanized steel develops a zinc oxide barrier upon contact with water, effectively preventing air and moisture from reaching the metal surface. This double-layer protection ensures durability even in high-humidity, acidic, or alkaline environments, prolonging the tank's lifespan and maintaining the hygiene and safety of stored water.

Thermal Insulation Performance

The composite structure of stainless steel and galvanized steel provides excellent thermal insulation. Stainless steel, with its low thermal conductivity (around 16 W/m·K), slows heat transfer from stored water. The galvanized outer layer adds further insulation, reducing heat dissipation. Compared to single-material tanks, the BDF water tank minimizes temperature loss by 20%–30%, helping to maintain water temperature for longer durations. This makes it ideal for applications requiring consistent water temperatures, such as hospitals, laboratories, and industrial water systems.

Stable Water Pressure Control

The BDF water tank operates on a gravity-fed system combined with internal pressure differentials to control water flow. As the water level rises, increased gravity boosts pressure at the bottom, pushing water through the outlet pipes automatically. When the level drops, the reduced pressure difference triggers the inlet to refill the tank. This automatic adjustment mechanism ensures a consistent water supply and prevents pressure fluctuations. It is particularly beneficial for high-rise buildings and facilities where stable water pressure is essential.

Easy Maintenance and Cleaning

The interior of the BDF water tank is crafted from high-quality stainless steel with a polished, smooth surface that resists scale and impurity buildup. This design eliminates tiny pores where contaminants can settle, significantly reducing cleaning frequency and cost. Routine maintenance typically requires only a simple rinse to keep the interior clean. This easy-clean feature makes the BDF tank especially suitable for environments with high hygiene requirements, such as hospitals and food processing plants, ensuring a sanitary water storage system.
