INDOOR AND OUTDOOR ROTH OIL TANKS
Double-Wall Construction
- Primary tank: High-density, seamless polyethylene that resists corrosion.
- Secondary (outer) tank: Galvanized steel that provides containment in case of an inner tank failure.
- This dual-layer system offers a second level of spill protection.
Leak Detection
- Roth tanks often include a visual leak indicator (usually a gauge or sensor) between the walls, providing early warning before a catastrophic leak happens.
Corrosion-Free Interior
- The inner plastic tank won’t rust, unlike traditional steel tanks. This greatly extends lifespan and reduces contamination risk in the fuel supply.
Longer Lifespan
- Many Roth tanks come with warranties of up to 30 years, compared to ~10–15 years for standard single-wall steel tanks.
- Less risk of tank failure due to rust or water intrusion.
