The Snyder Industries 120 Gallon Open Top Batch Storage Tank (SII-570TDVOT-45) is a white polyethylene cylindrical tank built for batch mixing, dosing, and short-cycle storage where you need fast top access. It stands 46.6 inches tall on a 30 x 30 inch footprint, so it fits a tight pad or platform while still giving you a deep working column for an agitator or fill line. As an open top tank, you load, inspect, and clean it from above without fighting a fixed lid - the reason crews reach for this Snyder white open top tank for water and process-batch duty.
Will it work for your job?
This is a 120 gallon vertical open tank rated to specific gravity 1.9, which means the wall is engineered to hold contents far heavier than plain water. Filled with water (1.0 SG) the contents weigh about 1,001 lb; loaded to its maximum rated content density the tank carries up to 1,902 lb. Use those two numbers to size your stand, pad, or steel skid - the structure under the tank must carry the heaviest batch you plan to run, not just a water fill. The 1.9 SG rating is a real upgrade, not just a spec line: it puts heavier brines and slurries within the wall rating, so buying the 1.9-rated tank future-proofs you if your batch chemistry gets denser down the road. The 30 x 30 inch footprint and 46.6 inch height also set your overhead clearance for filling and for clearing any mixer shaft. If you are unsure whether 120 gallons matches your batch turnover, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide before you commit.
Working volume and access on an open top
Plan your working volume below the rim. An open top tank loses usable depth to freeboard during agitation, so leave headroom for splash and to keep contents off the open lip - the 46.6 inch height is the tank wall, not the level you should fill to under a running mixer. The same logic that governs freeboard sizing is worth reading if you are dialing in batch levels; see our Snyder freeboard sizing guide for the freeboard-and-real-usable-volume math (the freeboard concept applies even though this is a single-wall open-top vessel). Because the top is open by design, plan for evaporation, debris, and contamination control: specify a loose cover sized to the 30 inch top opening, and call 866-418-1777 to confirm cover availability before you order.
The mistake to avoid
The 1.9 SG rating is a wall-strength rating, not a license to skip a real foundation. Set this tank on a smooth, fully supporting flat surface; an open top cylinder concentrates load straight down through its base, so an uneven pad or partial support invites stress at the floor. For above-ground work review our concrete pad sizing framework, and if this tank feeds a reuse or aggregation train see our industrial water reuse tank topology guide. No fittings or bulkhead outlets are listed in our data for this tank, so confirm dimensions and any available fitting or bulkhead options against the technical drawing on this page - and call before ordering plumbing.
This tank ships LTL freight from the Snyder plant in Marked Tree, AR, and freight is quoted live to your ZIP. ZIPs closer to northeast Arkansas generally quote lower LTL, while far coasts cost more, so run your real number with our Freight Cost Estimator before you compare freight cost - or call 866-418-1777 to confirm specs, lead time, and delivery.
