Snyder Industries 3600 Gallon 15 Degree Plastic Cone Bottom Tank

Why 15 degrees

Cone angle is a trade between drain speed and headroom. The cone bottom buyer's guide sets out the three common angles: 15 degrees for free-flowing liquids where ceiling height is the constraint, 30 and 45 for slurries and suspensions that need gravity to keep solids moving to the outlet. For fertilizer solutions, water treatment chemicals and most liquid blends, 15 degrees drains clean and saves height. The tank pairs with a cone stand from the stand compatibility matrix; match the stand to the 102 inch diameter and the 15 degree angle exactly, because a cone resting on the wrong ring loads the wall instead of the bottom. Smaller cones in the same logic are covered in the 2,500 gallon 30 degree cone bottom guide and the 300 gallon 30 degree guide, which show what the steeper angle costs in height at smaller sizes.

The chemical and the weight it puts on the stand

At water density the tank holds 30,024 pounds; at its 1.9 rating it is built for 57,046 pounds of contents, and every pound of that goes into the stand legs and then into the pad, so size the pad for the rated load, not the water load. Confirm resin compatibility in the chemical compatibility database and keep service below 120 F / 48 C. The list at the end of this page gives the chemicals rated for this tank with the fitting and gasket material for each. Fittings are specified at order; the tank top fitting placement guide explains where the vent, fill and level fittings go on a cone tank so a maintenance crew never has to work over an open manway. If the process needs a containment-rated companion vessel, the Snyder Captor 110 percent containment comparison is the reference.

The 3,600 gallon family and its neighbors

The four 3,600 gallon parts are one mold in different resin grades and colors. Compare the neighbors: the 3,000 gallon 5150000N40 is 90 inches across and 144 inches tall, 19 inches taller than this tank for 600 fewer gallons, because it stands on a steeper cone. The 3,900 gallon tank on the same 90 inch footprint reaches 180 inches. If your ceiling is the limit, the wider 15 degree tank wins on both counts.

Freight and installation

At 102 inches across it is oversize freight (NMFC 156600-03), flatbed only, quoted by lane through the freight cost estimator; the listed price is before freight and the stand ships separately. Three year warranty. Size the pad under the stand legs for the full 57,046 pound load, and confirm capacity against process volume with the tank sizing calculator and the tank sizing guide. Set the stand first, level it, then lower the tank into it; a cone tank that is stood on its cone even briefly can be damaged.

One mold, four resin grades

The N40, N43, N45 and N46 suffixes on the 3,600 gallon part are the same 102 by 125 inch shell in different resin grades and colors, all at 1,090 pounds. The grade is the thing to specify, not the shape: it sets which chemicals the wall tolerates and whether the tank is suited to sunlight or indoor service. Tell us the chemical, its concentration and where the tank will stand, and we will name the grade; the part number follows from that. Liquid fertilizer blends, water treatment chemicals and process rinse water are the common duties for a 15 degree cone at this size, because each of them needs to drain to the last gallon between batches.
