The Chem-Tainer 200 Gallon Double Wall Waste Oil Tank (SKU TC4153DC) packages a 200-gallon primary tank inside an integral secondary containment shell, so a single freestanding unit gives you the catch basin that aboveground storage rules demand without building a separate berm. The number to size your install around is weight: filled with water the tank carries about 1,668 lb, but at its full 1.9 specific gravity rating the contents can reach roughly 3,169 lb, so rate the pad, anchoring, and any spill platform for ~3,169 lb, not the water figure. It stands 53 inches tall on a 41.0 x 41.0 inch square footprint, molded from polyethylene in safety yellow with an oil level gauge already fitted. That 1.9 SG is the heaviest-rated configuration offered for this tank, so treat it as the ceiling spec rather than a stepping stone to a denser-service unit.
Will it work for your application
Size the load before you plumb anything. The square 41 x 41 inch base keeps the center of gravity low for a vertical tank of this height, and the molded oil level gauge lets an operator read tank volume at a glance during loadout while the secondary wall buys time to catch a primary leak before it reaches the floor. To match this 200 gallon double wall tank to your throughput and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. Confirm fitting and outlet locations against the technical drawing on this page before you commit to a piping layout.
Chemical compatibility
This tank is molded from polyethylene and rated to 1.9 specific gravity, which makes the same shell suitable for a broad range of dense liquids beyond waste oil. One honest caveat first: the resin code in our data reads HDLPE?, and because HDLPE versus XLPE changes chemical-service ratings, the entire compatibility list below stays provisional until you confirm the exact resin with us before chemical service. Fitting and gasket materials matter as much as the tank wall, so spec them to the chemical. Verified-compatible chemicals from the OEM chemical-resistance chart include acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50%, calcium chloride at 40%, ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20% and magnesium chloride at 30% (all PVC fittings, EPDM gaskets); sodium carbonate at 30%, potassium carbonate at 50%, potassium hydroxide (saturated), sodium thiosulfate at 40%, sodium bisulfate and sodium bisulfite (PVC or PVC/PP, EPDM); and ethylene glycol (100%), propylene glycol, urea solution at 50%, DEF at 32.5% and zinc orthophosphate (DEF and zinc orthophosphate take 316SS fittings; urea takes PP/PVC, EPDM). Aggressive oxidizers and strong acids run on Viton gaskets: hydrochloric acid at 37%, hydrofluoric acid at 48%, hydrofluosilicic acid at 26%, hydrogen peroxide at 50%, phosphoric acid at 85%, sodium hypochlorite under 16.5% and sulfuric acid at 98% (sulfuric on CPVC fittings). Peracetic acid at 30% needs 316SS fittings with Aflas gaskets. Polyaluminum chloride runs PVC/EPDM, and ozonated water up to 10 PPM runs PVC/EPDM (no dedicated page yet). Every one of these is concentration- and temperature-specific on the OEM chemical-resistance chart, so verify your exact concentration and service temperature before ordering, and start at our chemical compatibility resource.
Don't make this mistake
The single biggest error on a double wall tank like this is treating the 1.9 SG rating as a license to skip the gasket and fitting check. The polyethylene wall handles the chemical, but a PVC fitting or an EPDM gasket on the wrong service is where leaks start, and a leak inside a secondary-containment unit is exactly what regulators inspect for. Before this tank goes into a permanent install, square the secondary containment, level alarm, and inspection cadence against the rules that apply to you. Our walkthroughs on RCRA 40 CFR 264.193 secondary containment and leak detection, Florida DEP Chapter 62-762 AST compliance, spillover redundancy and high-level alarm architecture, and double-wall tanks for SPCC 40 CFR 112 cover the documentation and hardware inspectors look for.
