The Snyder Industries 55 Gallon Open Top Tank System is a total-drain, cone-bottom vessel built in white High Density Linear Polyethylene with a 1.5 specific gravity rating. The full cone, not a partial slope, is the reason to choose this over a flat- or sloped-bottom 55: contents move toward the bottom under gravity so you are not fighting a residual heel after each batch. Confirm the cone angle and the exact drain geometry from the technical drawing on this page. The open top gives you full access for filling, mixing, cleaning, and visual inspection, and at 39 inches tall on a compact 22 x 22 inch footprint it tucks into tight process corners and under fill lines where a wider tank would not fit.
Will it work for your job
This is a 55 gallon working tank. Filled with water it carries 459 pounds, and the 1.5 specific gravity rating supports contents up to a maximum 688 pounds, so you have headroom for liquids heavier than water as long as you stay within that rated weight and confirm chemical compatibility separately. The 22 x 22 inch footprint is the number to design your stand and containment around. Because this is an open top cone bottom tank, it needs a support stand or skirt that holds the cone up off the floor and lets it drain freely, so build that base to the 22 x 22 dimension. For the outlet and bulkhead detail, confirm the size and cone angle from the technical drawing on this page rather than assuming a fitting, then work through our cone bottom discharge engineering guide and our outlet sizing math for high-solids versus low-solids service to match the discharge to your fluid.
Open top cone bottom versus a sloped bottom
If your operation is a daily total dump-out, the full cone here drains more cleanly than a partial slope. If you are weighing the two geometries for head loss, drainage rate, and residual heel, our comparison of sloped-bottom versus cone-bottom tanks walks through the trade-offs. To confirm 55 gallons is the right working volume for your throughput and turnover, run the numbers in our Tank Sizing Calculator and review the Tank Sizing Guide.
The mistake to avoid
The most common error with a cone bottom tank is mounting it without a properly engineered stand under the cone. An open top cone bottom needs full vertical support beneath the cone so the weight bears correctly and the tank drains free. The other mistake is reading the 1.5 specific gravity rating as a green light for any chemical. That number governs weight, not chemical resistance. For any service beyond water, verify the contents against an OEM chemical-resistance chart at your concentration and temperature, and stay within the 688 pound rated contents weight.
This open top cone tank ships LTL freight from our plant in Marked Tree, AR, with the rate quoted live to your ZIP code. The 39 inch height, 22 x 22 inch footprint, and roughly 688 pound maximum loaded weight are what the freight class and your stand design key off. Get your number on the Freight Cost Estimator, or call 866-418-1777 and we will help you size the tank, the stand, and the discharge for your process.
