The Snyder Industries 150 Gallon Industrial HDLPE Rectangular PCO Tank is a 1.5 specific-gravity portable tank built for industrial chemical handling and process duty. It measures 48 inches long by 36 inches wide by 29 inches tall, giving it a 36.0 x 48.0-inch footprint that tucks into containment basins, seats on a skid, or banks against a wall in a way no round drum of the same volume can. Molded in white polyethylene at 150 gallons and rated for liquids up to 1.5 specific gravity, this rectangular PCO tank covers a wide band of common water-treatment and process chemistries.
Will this tank work for your application?
Start with weight, because that is where rectangular tanks surprise people. Filled with plain water this tank carries about 1,251 pounds; at its full 1.5 specific gravity rating, contents can reach roughly 1,876 pounds. Spread over the 36 x 48-inch footprint (12 square feet), a full load works out to about 156 pounds per square foot, so size the pad, skid, or SPCC containment basin under it for nearly a ton of liquid before you fill. The flat-sided geometry is what makes this the "150 gallon rectangular" tank people look for instead of a drum: it nests against walls, lines up in banks, and seats cleanly inside rectangular spill pallets. See the technical drawing on this page for overall dimensions, and note this tank is supplied for field-configured fittings rather than a fixed factory port layout - call 866-418-1777 to confirm the vent, fill, and outlet package for your install.
Chemical compatibility
This is a polyethylene tank molded from HDLPE with a 1.5 specific gravity rating. The resin grade is not fully confirmed in our records, so verify whether your unit is HDLPE or XLPE before committing it to chemical service - that distinction changes long-term resistance to certain chemistries, and 866-418-1777 can confirm it against the Snyder spec for this SKU. Compatibility, fitting material, and gasket material below are concentration- and temperature-specific; always check them against the OEM chemical-resistance chart for your exact conditions. At this tank's 1.5 SG rating, the following are workable when plumbed with the right fitting and gasket materials:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
The most common mistake on a 1.5 SG tank is putting a denser chemistry in it. Several chemicals our chart flags for this resin require a higher 1.9 specific gravity tank rather than this one - including ethylene glycol, ferric chloride, hydrochloric acid, hydrogen peroxide, phosphoric acid, sodium hypochlorite, sulfuric acid, and peracetic acid, among others. Several of those also call for Viton instead of EPDM gaskets, and peracetic acid specifically requires Aflas - not Viton - so do not substitute. If your chemistry is on that list, do not run it in this 1.5 SG tank; step up to the 1.9 SG version of this Snyder rectangular tank instead, and call 866-418-1777 for the matching SKU. Use the Chemical Compatibility Database to confirm your exact chemical, concentration, and temperature.
Plan the fittings and the layout
Where the vent, fill, level, and drain land on a rectangular tank matters more than on a drum, because flat-wall tanks bank tightly and a poorly placed fitting fouls a neighbor or blocks maintenance access. Our guide on top fitting placement strategy walks through vent, fill, level, drain, and vapor-recovery layout to avoid cross-contamination and operator error. For instrumentation, the tank level gauge selection guide compares radar, ultrasonic, hydrostatic, and magnetostrictive options for chemical service. If this tank goes into a regulated or hazardous-material area, the label and signage compliance guide covers NFPA 704, GHS pictograms, DOT placards, and OSHA HazCom marking.
