Rotomolded polyethylene tanks in this category are typically manufactured to ASTM D1998, and many use FDA 21 CFR 177.1520 compliant resin; certifications vary by model and manufacturer, so check each product's Specifications for what applies. UV stabilizers are co-extruded into the resin for outdoor installation. Maximum operating temperature 120°F for HDPE; higher for XLPE (cross-linked polyethylene). NSF 61 certified models available on request for potable drinking water applications — call to specify.
Freight & Delivery
Tanks ship LTL motor freight from the closest stocking warehouse to your delivery ZIP. Typical transit 5-10 business days. Liftgate available at delivery (per-shipment fee). Always inspect at delivery and note any damage on the bill of lading before signing — that is the LTL carrier claim trigger. Bulk-order consolidation reduces per-tank freight 25-40%. Same-business-day quotes: call 866-418-1777 with MPN, quantity, and delivery ZIP.
Sizing & Selection
Pick capacity first, then verify dimensions against your installation footprint. Most rotomolded tanks are built to OEM standard dimensions ± standard rotational-molding tolerance of ±2-3%. Vertical tanks need flat-pad foundation; horizontal/leg tanks need stand or cradle (check listing — some are sold with integrated stand, others require separate stand or band purchase). Application engineering: call 866-418-1777 for sizing, layout, and accessory recommendations.
