ACT-100® Double Wall Fiberglass Composite Underground Storage Tank

ACT-100® Features:

The ACT-100® is a double wall fiberglass underground storage tank: a steel primary tank encased in an FRP composite (fiberglass-reinforced plastic) outer coating with a 100-mil minimum dry film thickness. The steel shell carries the structural load while the fiberglass laminate forms a continuous dielectric barrier that isolates the tank from soil and stray-current corrosion. The double-wall design creates an interstitial space for continuous leak detection and monitoring.

  • Manufactured and listed to Underwriters Laboratories UL 58 (Steel Underground Storage Tanks for Flammable and Combustible Liquids) and UL 1746 (External Corrosion Protection Systems for Steel USTs)
  • Double wall steel construction with interstitial leak detection and monitoring
  • FRP composite outer coating, 100-mil minimum thickness, spark-tested to 15,000 volts for holiday-free coverage
  • Compatible with all blends of ethanol and biodiesel fuels; impermeable to petroleum products and vapors
  • Flat-end design lowers installation cost and increases site-layout flexibility
  • Multiple backfill options for money-saving installation
  • Compatible with a range of leak detection systems
  • Capacities from 2,000 to 20,000 gallons

ACT-100® Benefits:

  • Built to nationally recognized Steel Tank Institute (STI-SPFA) standards under a mandatory third-party quality-control inspection program
  • First five tanks per licensee approved by an STI inspector; unannounced plant audits thereafter
  • EPA-recognized corrosion-control technology under 40 CFR Part 280 (RCRA Subtitle I)
  • Steel construction is fully recyclable
  • Backed by Newberry’s limited product warranty: 10 years with the registered purchase of the tank, extendable to 30 years total for an additional fee, backed by STI/STICO

How ACT-100 protects against corrosion

ACT-100 combines two corrosion-control methods balanced for protection at minimum cost. First, the FRP composite cladding eliminates metal-to-soil contact: an abrasive-blasted steel surface (SSPC-SP6 modified commercial blast) receives a fiberglass-reinforced laminate applied to a 100-mil minimum thickness and spark-tested at 15,000 volts to confirm no holidays. Second, electrical isolation protects against stray-current corrosion: nylon dielectric bushings (Zytel 101) isolate threaded openings, flange isolation kits handle flanged connections, and every monitoring opening on a multi-wall tank is isolated. The finished tank passes a field spark test of 10,000 volts minimum.

FAQ

An ACT-100 is a double wall fiberglass underground storage tank: a steel primary tank clad in an FRP (fiberglass-reinforced plastic) composite coating that forms a continuous dielectric barrier against soil corrosion. It is built to Steel Tank Institute standards on a UL 58 / UL 1746 steel base and includes an interstitial space for leak detection.

Both are composite steel underground tanks that combine a dielectric coating with electrical isolation. ACT-100 (STI spec F894) uses a fiberglass-reinforced laminate; ACT-100-U (STI spec F961) uses a urethane composite cladding. The corrosion-control approach is the same; the coating chemistry differs.

Yes. The steel primary tank is compatible with all blends of ethanol and biodiesel and is impermeable to petroleum products and vapors. The nylon dielectric bushings used for electrical isolation are rated for gasoline, gasohol, and hydrocarbons.

The FRP laminate is applied to a minimum dry film thickness of 100 mils (2.54 mm) over the entire tank surface, verified with a non-destructive thickness gauge and spark-tested at 15,000 volts to confirm there are no holidays.

The double-wall design creates an interstitial space between the primary and secondary walls. That space is monitored continuously through an isolated interstitial monitoring pipe, so a breach in either wall is detected before product reaches the environment.

ACT-100 tanks carry a 10-year limited warranty with the registered purchase of the tank. An additional 20 years is available for an added fee when the tank is registered, for up to 30 years of coverage in total, backed by STI/STICO.

ACT-100 tanks are built on a UL 58 or UL 1746 listed steel tank to Steel Tank Institute (STI-SPFA) standards, under a mandatory third-party QC inspection program. The technology is recognized by the EPA under 40 CFR Part 280 (RCRA Subtitle I).

Newberry builds ACT-100 tanks in capacities from 2,000 gallons up to [TBD: confirm top capacity] gallons, in single, double, or triple-wall configurations. See the capacity chart above for dimensions and weights.
