The Snyder Industries 100 Gallon Industrial HDLPE Rectangular PCO tank is a 1.5 specific-gravity portable chemical tank that holds 100 gallons in a compact 30 in. wide by 38 in. long footprint, standing 31 in. tall in white polyethylene. The rectangular profile packs more usable volume into a tight floor plan than a round tank of the same gallonage, which makes it a practical fit for batch rooms, secondary-containment pads, and service-truck applications where a round 100 gallon vertical or a sprayer-style rectangular tank would waste space. If you have been searching for a 100 gallon rectangular tank from Snyder, this is the industrial-rated version built for chemical duty rather than open water.
Will it work for your job
This tank carries a 1.5 specific-gravity rating, so it is built to hold liquids up to 1.5 times the weight of water. Plan your stand and floor for roughly 834 lb at full water weight, rising to 1,251 lb at the maximum rated contents weight when you fill near the 1.5 SG ceiling - that is about 417 lb more than water alone, and it is exactly the delta that undersizes decks and skids sized only for water. On the 30 x 38 in. footprint (about 7.9 sq ft), the full chemical load works out to roughly 158 lb per square foot of distributed floor load, which is the figure to check your pad or mezzanine rating against. Use the Tank Sizing Calculator and the Tank Sizing Guide to match contents weight to your support structure before you fill, and consult the technical drawing on this page for fitting locations and exact dimensional callouts before you plumb it.
Chemical compatibility
The tank is molded in polyethylene rated to 1.5 specific gravity. The resin code in our data is unconfirmed, so confirm HDLPE versus XLPE with us at 866-418-1777 before committing this tank to chemical service - that distinction changes long-term resistance for some chemicals. Compatibility below is drawn from the OEM chemical-resistance chart and is always concentration- and temperature-specific; verify your exact conditions against the chart and our Chemical Compatibility Database.
Within the 1.5 SG rating, this tank is suited to the following, with the fitting and gasket materials the chart specifies for each. Note that every in-rating chemical uses EPDM gaskets, and DEF is the one exception that requires 316 stainless fittings rather than the PVC or PP the others use - do not default DEF service to PVC:
- Acetic Acid at 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% - PVC fittings, EPDM gaskets
- Calcium Chloride at 40% - PVC fittings, EPDM gaskets
- DEF (diesel exhaust fluid) at 32.5% - 316SS fittings, EPDM gaskets
- Ferrous Sulfate at 20% - PVC fittings, EPDM gaskets
- Magnesium Chloride at 30% - PVC fittings, EPDM gaskets
- Sodium Carbonate at 30% - PVC fittings, EPDM gaskets
- Urea Solution at 50% - PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
The mistake to avoid: matching SG to your chemical
The most common and most expensive error with a 100 gallon chemical tank is putting a heavy chemical into a tank rated below it. This is a 1.5 SG tank. Several common chemicals require a higher 1.9 SG tank instead and should not go in this one: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Watch the gasket and fitting callouts here too: the strong acids and oxidizers - hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, sodium hypochlorite, and sulfuric - require Viton rather than EPDM, sulfuric specifically calls for CPVC fittings, and peracetic acid needs Aflas gaskets with 316SS fittings. Rather than force any of these into this tank, the right move is the 1.9 SG version of this same tank - call 866-418-1777 and we will spec it on the same call and confirm the fitting and gasket package for your chemical. For fitting layout that keeps fill, vent, and drain from fighting each other, see our guide on tank top fitting placement strategy, and for labeling the finished installation correctly, our tank label and signage compliance guide.
