Gemini² Dual Containment® Tanks

Gemini² Dual Containment® Tanks have the same great features and benefits as cylindrical Gemini plastic tanks but have a larger capacity per footprint. These square tanks have 22% more capacity than cylindrical tanks of the same size. All tanks meet or exceed secondary containment regulations set under EPA 49CFR. These tanks are designed with a pump mounting surface, female threaded connections, and twist lid inspection port. The integral mouse door, molded directly into most Gemini models, is a recessed mouse door that allows for the inexpensive installation of an optional dual wall bulkhead fitting for flooded suction and bottom fill applications (fittings sold separately). The ProChem® Tank Stacker™, sold separately, is designed for tank installations where space is limited and can hold 10 and 20 gallon Gemini²® tanks. Tanks are also available by special order in heavy duty 1.9 specific gravity or XLPE 1.5 or 1.9 specific gravity; contact us for a quote.
