Double walled tanks feature a tank-within-a-tank design, providing built-in secondary containment to prevent leaks and environmental contamination. This safety-focused structure makes them indispensable across industries handling hazardous, corrosive or flammable liquids, complying with global regulatory standards for liquid storage. Below are the key application scenarios for these tanks.
Chemical Processing & Manufacturing
They are ideal for storing inorganic acids, solvents, and industrial chemicals. Constructed with HDPE or XLPE, the tanks resist corrosion and chemical reactions, eliminating the need for separate concrete containment areas. Small to large gallonage options suit both on-site production and bulk chemical storage, with leak detection in the interstitial space for early risk alerts.
Petroleum & Fuel Stations
Aboveground and underground double walled tanks are standard for storing petrol, diesel, and heating oil. Gas stations and fuel depots use horizontal or vertical models to save space while preventing soil and groundwater contamination from fuel spills. The outer layer acts as a robust barrier, and nitrogen-filled interstitial space adds fire and explosion protection for flammable liquid storage.
Municipal Water Treatment
Cities and municipalities rely on these tanks for storing water treatment chemicals like sodium hypochlorite. They ensure safe handling of water treatment solutions and wastewater pre-processing, reducing environmental incidents and meeting EPA secondary containment requirements.
Industrial & Commercial Facilities
Food and beverage, pharmaceutical, and biotech plants use double walled tanks for temperature-controlled storage and processing. Their jacketed design supports heat/cold circulation for fermentation, mixing, and product preservation. Additionally, construction sites and fleet depots use them for on-site fuel and coolant storage, with portable models fitting mobile operational needs.
