The intent of this specification is to provide the owner with a "Subbase" type rectangular aboveground UL listed closed top dike double wall fuel storage tank, specifically designed and sized for standby emergency backup generators.
The double wall tank is used when extra protection against fuel leakage to the surrounding environment is desired or required. The double wall tank not only contains fuel leakage from the inner tank, it is also sealed to prevent the entrance of rain and debris.
COM-FAB, INC. manufactures it's double wall tank in two pieces; the inner tank, and the double wall base. The inner tank is made of 12 ga. steel, with 10 ga. baffles... space every 20 inches for added support and rigidity. The tank is completely welded, and pressure tested at 5-7 pig for a minimum of 60 minutes.
The double wall base is made of 10 ga. main rails and 12 ga. top and bottom. There are also 3x4.1 channels below the double wall bottom to separate it from the concrete mounting pad. The double wall base supports all the weight of a generator as well as providing a rupture basin. The weight and vibration carrying part of the base is not mechanically connected to the inner tank, this reduces the risk of fatigue of the inner tank welds. The inner tank and the double wall top are welded together around the tank fittings only, to provide a completely sealed rupture basin. The rupture basin is fully welded, then tested with magna-flux penetrating dye.
The tank comes standard with the following fittings: fill, engine supply, engine return, inner tank drain, rupture basin drain, mechanical gauge, normal and emergency tank vents, and rupture basin vent.
