GEN-TANK® Generator Base Tanks
Learn about Generator Base Tanks

Customizable, leak-proof generator base tanks
We build double-walled, UL-2085 FIREGUARD® carbon or stainless-steel storage tanks of any size and capacity to meet your unique engineering specifications at our site in North Carolina, with quality and vacuum checks at every stage.
Our gen base tanks are true double-wall designed and UL-142 labeled for storing a wide range of flammable and combustible fuels and chemicals.
Save space and reduce maintenance costs
Our long-lasting, warranty-backed generator base tanks eliminate the need for day or self-contained storage tanks and upfit fuel storage or storage add-ons, reducing your overall tank maintenance costs.
Fast installation time
Our tanks are engineered and approved by the end user, and because of our end-to-end quality control process, installation time is faster, ensuring no rework and easy field fit.
UL-2085 FIREGUARD® Generator Tanks
Our fire-protected FIREGUARD® generator base tanks are UL-2085 and UL-142 labeled tanks designed for storing flammable and combustible liquids. Every tank is subjected to a rigorous and continuous quality verification standard throughout the fabrication process.
They are manufactured:
- As “low-profile” rectangular tanks (using carbon or stainless steel) able to support the structural load of the generator and enclosure.
- Utilizing a unique, lightweight monolithic insulation material between the inner and outer tanks for leakage monitoring.
- According to your custom fabrication specifications with capacity up to 44,000 gallons.
- To provide two-hour fire rating, impact and ballistic protection.
- In compliance with NFPA-30 and International Fire Code requirements for Fire Protected Fuel Storage Tanks.

Stay in Compliance! Know the Regulations.
UL-142 Double Walled Generator Base Tanks
Our UL-142 Generator Base tanks are true double-wall designed and UL-142 labeled for storing flammable and combustible liquids. Every tank is subjected to a rigorous and continuous quality verification standard throughout the fabrication process.
Unlike some tanks, our generator base tanks:
- Have a testable secondary tank (not just a dike or basin) with primary tank monitoring access.
- Are manufactured as “low-profile” rectangular tanks (using carbon or stainless steel) and can support the structural load of the generator and enclosure.
- Can be built according to your custom fabrication specifications with capacity of up to 47,000 gallons.
- Gen-base tanks comply with NFPA-30 and International Fire Code requirements for fuel storage.
