Plastic Double Wall Tanks

Double wall tanks (dual wall tanks, double containment tanks, double walled tanks, captor tanks, day tanks) are constructed with a primary inner tank and secondary containment tank. This tank in a tank assembly provides secure containment of chemicals, waste, and other liquids. Tanks are constructed using either high density polyethylene (HDPE) or cross-link polyethylene (XLPE). Both of these resins offer different levels of chemical containment depending on their use. HDPE and XLPE double wall tanks are rotationally molded for industrial strength durability and protection from environmental contamination. UV inhibitors are added to the resin for added protection against direct sunlight. These features make plastic double wall tanks ideal for indoor or outdoor storage. Each tank is manufactured with FDA approved resin that complies with FDA standards 21 CFR 177.1520 (1) 3.1 and 3.2 for the storage of potable water. Snyder captor tanks are constructed to meet ASTM D1998 - 06 standards for poly upright storage tanks.

Double wall storage tanks were designed for commercial and industrial use. They are commonly used for chemical storage in manufacturing facilities, plants, exploration sites, and warehouses. Some of the liquid types used with these tanks include calcium chloride, sodium hydroxide, biodiesel, fertilizer, brine, diesel exhaust fluid, polymer, and urea. Snyder industries supplies a chemical resistance chart that makes it easy to select the right specifications for a variety of chemicals.

Double containment tanks are customized for their use. All of these tanks come with multiple fitting, manway, and lid options. An assortment of accessories are available for certain sizes, including leak detection sensors, digital display indicators, and OSHA compliant ladders, nozzles, tie downs, and interior down pipes. Heat tracing and insulation are also available for larger tanks.

Sizes start at 15 gallons and extend up to 13,700 gallons. Each dual wall tank comes with a 3 year manufacturer warranty. Tanks are shipped fully assembled to help save on field assembly time.
