Roth Double Wall Tank Plus Package, 110 Gallon

The outer tank is fitted with an oil and fire-resistant seal, and the inner tank is constructed from seamless, high-density polyethylene that will not corrode, making this tank suited for petroleum-based fluids such as oil. The entire double wall system is designed to prevent spills, leaks, and fires associated with these types of fluids.

The double wall design creates two independent layers of containment: the seamless blow-molded polyethylene inner tank holds the fluid, while the outer weld-free galvanized steel shell — sealed with an oil and fire-resistant roll seam — acts as a backup barrier. Together they are engineered to prevent spills, leaks, and fire hazards from reaching the surrounding environment.

In addition to the 110-gallon double wall tank, the Plus Package includes an Optical Leak Alarm for early leak detection, a Fluid Level Gauge so you can monitor stored fluid inventory without opening the tank, and a Lockable Fill Cap with Vent to secure the fill point against unauthorized access.

No pump or dispensing equipment is included in this package. The kit covers storage, leak monitoring, level gauging, and a secured fill cap — any pump, hose, or dispensing hardware would need to be sourced separately.

The tank measures 28 inches wide by 29 inches deep by 48 inches tall with a 110-gallon capacity. When planning the installation space, allow additional clearance around the unit for accessing the fill cap, reading the level gauge, and servicing the optical leak alarm.

Both the inner and outer tanks are built for long-term durability: the inner blow-molded polyethylene tank will never corrode, and the outer galvanized steel shell is designed to be rust-resistant inside and out, reducing maintenance concerns associated with traditional all-metal storage tanks.
