Gemini Dual Containment® Tank Systems & Level Gauges

Gemini Dual Containment® Tanks are an excellent choice when you're looking for safe storage of chemicals and other products where a Secondary Containment Tank system is required. 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 15 and 20 gallon Gemini® 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.
