Custom Roto Molding Inc chemical storage tanks provide efficient chemical storage for commercial and industrial use. The chemical storage tanks range in size from 500 gallons to 3,000 gallons and are available in high density polyethylene (HDPE) or cross linked polyethylene (XLPE).

*Chemical tanks with containment are available in sizes up to 2,000 gallons.

Tank Material:

HDPE - High Density Polyethylene is a thermoplastic polymer created from petroleum. HDPE has a high impact resistance and melting point.
XLPE - Cross Linked Polyethylene offers superior heat and chemical resistance, stress cracking resistance and low temperature impact strength. Offers superior corrosion and chemical resistance than HDPE.

Specific Gravity:

Specific Gravity is an indicator of the density that can be stored in a tank. A 1.5 SG means the tank can store liquid up to 1.5 times as dense as water.

HDPE - 1.5 SG
HDPE HD - 2.0 SG
XLPE - 2.0 SG

*Note: HDPE tank sizes up to 750 gallons have 1.5 SG; HDPE tank sizes 825 gallons and greater have 2.0 SG.

Tank Options:

With Containment: Adds a second open top tank with a larger diameter that provides secondary containment for the primary chemical tank.

Note: Chemical tanks with containment are not available for all tank sizes.

Chemical Tank Features:

Includes threaded lid with breather.
2 inch NPT Polypro bottom fitting (option to upgrade to stainless fitting for harsher chemicals).
Natural white color.
Choice of HDPE or XLPE material.

Chemical Tank with Containment Dimensions (Diameter x Height in inches):

When purchasing a chemical tank with containment, the containment is provided by a second open top tank. The primary chemical tank has a smaller diameter than the open top tank so that it can be stored inside the wider open top tank.

The dimensions below represent the open top tank (total weight represents the weight of the primary chemical tank + the weight of the open top tank):

500 Gallon: 48" D x 94" H open top containment; total weight 304 lbs.
525 Gallon: 72" D x 38" H open top containment; total weight 190 lbs.
550 Gallon: 60" D x 60" H open top containment; total weight 220 lbs.
750 Gallon: 60" D x 76" H open top containment; total weight 362 lbs.
825 Gallon: 72" D x 52" H open top containment; total weight 245 lbs.
1,000 Gallon: 90" D x 52" H open top containment; total weight 412 lbs.
1,025 Gallon: 72" D x 80" H open top containment; total weight 450 lbs.
1,100 Gallon: 102" D x 39" H open top containment; total weight 395 lbs.
1,225 Gallon: 90" D x 69" H open top containment; total weight 668 lbs.
1,500 Gallon: 90" D x 69" H open top containment; total weight 713 lbs.
1,600 Gallon: 102" D x 63" H open top containment; total weight 640 lbs.
2,000 Gallon: 102" D x 80" H open top containment; total weight 1,025 lbs.
