Potable Drinking Water Tank Semi-Trailer
The Potable Drinking Water Tank Semi-Trailer is a specialized, high-sanitary stainless steel transport trailer engineered strictly for the hygienic, contamination-free road haulage and municipal distribution of potable drinking water, purified water, and liquid food ingredients (such as milk, juice, or edible oil). Built in full compliance with international food safety and sanitation standards (such as FDA, NSF/ANSI 61, and ISO9001), the tank shell is fabricated from high-grade austenitic stainless steel (SUS304 / SUS316L) with mirror-polished, passivated internal surfaces to prevent bacterial growth, rust, and chemical leaching. Featuring an insulated double-wall structure (or optional single wall with outer aluminum cladding) to maintain water temperature, it is equipped with internal anti-surge wave baffles, a top-mounted breathable sanitary manhole, a rear stainless steel pump cabinet, and a sanitary self-priming centrifugal pump. Paired with 3 commercial heavy-duty axles, air ride or mechanical suspension, and WABCO ABS/EBS pneumatic braking, it delivers superior highway stability, fluid safety, and long-term durability. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Food-Grade SUS304/SUS316L Stainless Steel & Passivation
- Sanitary Alloy Construction: Fabricated entirely from certified austenitic stainless steel (SUS304 or SUS316L), preventing rust, oxidation, and mineral contamination to guarantee absolute drinking water safety.
- Mirror Polishing & Chemical Passivation: All internal welds are ground flush, mechanically polished, and chemically passivated ($\text{Ra} \le 0.4 \ \mu\text{m}$), eliminating micro-crevices where bacteria or algae could form.
- Clean-In-Place (CIP) Compatibility: Equipped with top-mounted rotating spray cleaning balls and breathable sanitary manholes, enabling efficient internal sterilization between hauling cycles.
2. Anti-Surge Baffles & Optional Thermal Insulation
- Multi-Chamber Wave Baffles: Internal dish-shaped stainless steel baffles compartmentalize the liquid payload, drastically reducing hydraulic surge and stabilizing the vehicle during sudden braking or cornering.
- Climate-Control Insulation Jacket: Available with a high-density polyurethane foam insulation layer encased in a protective outer stainless steel skin, preventing water freezing in sub-zero regions or excessive heating in tropical climates.
- Low-Center-of-Gravity Saddle Mounting: Securely integrated into a robust structural sub-frame via engineered stainless steel saddles, keeping the center of gravity low for enhanced highway handling.
3. Hygienic Pumping, Piping & Running Gear
- Stainless Steel Sanitary Pumping System: Fitted with a dedicated stainless steel self-priming centrifugal pump and quick-connect discharge manifolds for rapid, contamination-free loading and unloading.
- Adjustable Air Ride Suspension: Pneumatic air suspension cushions sensitive piping, tank mounts, and structural welds from harsh road shocks, ensuring smooth transport.
- WABCO ABS/EBS Braking Safety: Dual-line pneumatic braking system incorporating WABCO ABS/EBS and emergency relay valves for dependable stopping power under full liquid capacity.
Commercial & Logistics Terms
- Warranty Policy: 3 to 5-Year warranty for the stainless steel tank shell structure; 1-Year warranty for axles, pump, and valving components.
- Delivery Lead Time: 30 – 35 working days upon order confirmation and engineering drawing approval.
