Under-ground Storage Tanks

Permatank is an F-922 (Fiberglass Secondary Containment), UL-58 and UL-1746 labeled tank, designed for underground storage of flammable and combustible liquids. These tanks are manufactured of carbon steel with an FRP jacket providing an interstitial monitoring space.

ACT-100 tanks are F-894 (External Corrosion Protection of Composite Steel USTs), UL-58 and UL-1746 labeled and designed for underground storage of flammable and combustible liquids. ACT-100 tanks are manufactured of double-wall carbon steel with a 100 mil FRP laminate coating without the need for external cathodic protection.

ACT-100U tanks are F-961 (External Corrosion Protection of Composite Steel USTs), UL-58 and UL-1746 labeled and designed for underground storage of flammable and combustible liquids. ACT-100U tanks are manufactured of double-wall carbon steel with a 70mil urethane coating without the need for external cathodic protection.

Above-ground Storage Tanks

Flameshield® tanks feature double-wall steel construction. These tanks are UL142 labeled and 2-hr fire-resistant.

Fireguard® tanks feature double-wall steel construction, with a lightweight concrete insulating material between the inner and outer tank. Fireguard tanks meet the “protected” tank designation and are UL2085 labeled. These tanks offer 2-hour fire protection and are impact-resistant and ballistic-resistant.

The tables shown below describe the typical features and specifications offered with fuel storage tank systems applied to power generation applications. Other configurations include:

  • Rectangular tanks with custom sizes to meet job-specific requirements.
  • Generator Sub-base Tanks (UL142 or UL2085)
  • Water and chemical storage tanks.
  • Dispensing equipment for fleet vehicles or plant operations.
  • Customized electronic level sensors, pumps and accessories.
  • Split tanks for consolidated fuel inventory.
