Oil Tanks

Southern Tank designs and fabricates oil storage tanks for data centers, military, commercial, industrial, and agricultural applications. Whether storing fresh oil for equipment and vehicle maintenance or collecting used oil for heating, disposal or recycling, our carbon steel or stainless steel tanks are a trusted solution.

Our aboveground models can be double wall or used in conjunction with a containment pan to support EPA compliance and facility-specific needs.

Common Oil Tank Applications

Our tanks are used across many sectors, including:

• Auto shops, fleet service centers and recycling yards – storing motor oils, transmission fluid, and hydraulic oil and used oil collection
• Industrial facilities – managing process and lubrication oils
• Farms and ag co-ops – storing bulk oil for tractors and equipment
• Waste management firms – collecting used oil prior to off-site transport
• Municipal garages and DOT facilities – for centralized oil handling or collection
• Power transmission and distribution – transformer oil for wind power, retrofilling, solar

Our tanks are built to meet your operational and regulatory needs, whether it’s a fresh supply or a safe place for reclaiming used oil.

Addressing Emerging Clean Energy Needs

Our oil tank technology is expanding to meet clean energy needs with tanks designed to safely contain FR3® natural ester dielectric fluid, a preferred insulating liquid for transformers in various energy sectors. For wind power applications, including both onshore and offshore installations, our tanks support the compact and lightweight FR3 fluid transformer designs, facilitating efficient energy generation. In solar power systems, our containment solutions accommodate the enhanced fire safety and environmental benefits of FR3 fluid, making them suitable for land-based and floating solar plants.

Additionally, for retrofilling existing transformers, our tanks are compatible with FR3 fluid’s superior moisture management and extended insulation life, providing a practical upgrade path from mineral oil.
