The Norwesco 1600 Gallon Horizontal Elliptical Cradle Tank ships white, molded from FDA-approved polyethylene with a factory poly baffle and fittings installed. It is built for mobile and transport service: an elliptical cross-section that sits low on its cradle so a partial load stays stable down the road, and the internal baffle is there to damp sloshing when you move that load. If you are shopping this as a 1600 gallon Norwesco horizontal tank with a baffle and fittings, this is that tank.
Will it work for your load?
Match it to your trailer deck first. Discrete dimensions: length 138 in, width 78 in, height 54 in, for a 78 x 138 in footprint. Empty it weighs 464 lb. It carries a 2-inch outlet, a 16-inch lid, and is rated to a maximum of 120 F / 48 C.
This is a 1.5 specific-gravity tank, which sets the ceiling on what you can safely haul. Filled with water at SG 1.0 the contents alone weigh about 13,344 lb; loaded to its full 1.5 rating the tank carries up to roughly 20,016 lb of product, or about 20,480 lb gross once you add the 464 lb empty tank, which is the number to size your axles and cradle capacity against. If you are matching this tank to a specific volume or a heavier fluid, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you buy. See our guide on tank baffle engineering for sloshing and wave damping and the Norwesco applicator and leg tank DOT scope for how these get classified in the field.
Chemical compatibility
This is a polyethylene tank (resin listed as HDLPE?) rated to 1.5 specific gravity. Confirm HDLPE versus XLPE before putting it into chemical service. Per the Snyder Industries OEM chemical-resistance chart, which is concentration- and temperature-specific, this 1.5-SG tank suits these products when you match fittings and gaskets and stay within the tank's 120 F / 48 C limit: Acetic Acid (60%, PP/PVC fittings, EPDM gasket), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). For DEF haulers this tank is well within rating: DEF (32.5%, req SG 1.35, 316SS fittings, EPDM) and Urea Solution (50%, req SG 1.35, PP/PVC, EPDM) both sit comfortably under the 1.5 rating. Always verify your exact chemical, concentration, and temperature against the chart and our chemical compatibility resource.
The mistake to avoid
Do not assume this 1.5-SG tank covers every chemical, and do not spec generic fittings from memory. Heavier or more aggressive fluids need a higher specific-gravity tank: Sulfuric Acid (98%, CPVC fittings and Viton gasket, not generic PVC), Hydrochloric Acid (37%), Sodium Hypochlorite (under 16.5%), Hydrogen Peroxide (50%), Ferric Chloride (50%), Ferric Sulfate (60%), Phosphoric Acid (85%), Hydrofluoric Acid (48%), Hydrofluosilicic Acid (26%), Ethylene Glycol (100%), Propylene Glycol, Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Sodium Bisulfate, Sodium Bisulfite, Sodium Thiosulfate (40%), Zinc Orthophosphate, and Peracetic Acid (30%, which needs 316SS fittings and an Aflas gasket) all call for a 1.9-SG tank, several with Viton or Aflas gaskets rather than EPDM. Spec the tank to the fluid, not the other way around, and note the fitting and gasket materials against the technical drawing on this page.
