Fireguard UL-2085 Fire Protected Storage Tanks

The UL-2085 Fireguard Tank is a fire protected double wall aboveground storage tank. This tank features a unique lightweight thermal insulation material within a primary inner tank and epoxy coated secondary outer tank. The insulation material provides fire and heat protection for the inner tank.

Fireguard Tanks are available in sizes up to 50,000 gallons; horizontal or vertical, rectangular or cylindrical. Can be divided into multiple compartments. Support designs are available for any seismic requirement. These tanks are compatible with a large range of chemicals and fuels, including ethanol and biodiesel.

Fireguard tanks are built to Steel Tank Institute Standards. They are UL-2085 labeled and meet all national codes for fire protected above ground storage tanks, including NFPA 30A, UFC (Uniform Fire Code), international and state fire codes. These tanks exceed the UL 2 hour fire test and also met temperature requirements when the furnace test was extended to 4 hours.

Fireguard tanks meet all requirements for 110% capacity secondary containment, ballistics and vehicle impact resistance. The primary and secondary tank can be tightness tested with standard testing procedures on site. The interstitial space can be monitored for leak detection. Equipped with emergency vents for prevention of excess pressure build up.

By insulating the product inside, fireguard tanks reduce ambient temperature variations and emissions. These tanks meet CARB requirements (California Air Resource Board)

Fireguard Tanks VS Concrete Encased Tanks

The insulation material of fireguard tanks is 75% lighter than that of concrete tanks. This reduces costs for shipping and relocation, also simplifies installation. Fireguard tanks feature the epoxy coated steel outer wall, which provides protection from weathering, resistance to corrosion, durability, and low cost maintenance. Concrete tanks are subject to etching, cracking and spalling. The steel construction of fireguard tanks allows for recycling, making disposal easier.

Fireguard tanks come with a 30 year warranty
