GRAF - Model Carat S -Underground Tank

Logistical advantages of the Carat
The Carat tank consists of two half shells which can be stacked on top of each other, allowing multiple tanks to be stacked on a single pallet for shipping. For example, it is possible to stack five 6,500 ltr Carat tanks, or nine 2,700 ltr Carat tanks on a single pallet. This allows a standard 40 ft. shipping container to house a total tank volume of up to 130,000 ltrs! The tanks unique stacking feature directly reduces transport costs and environmental impact from vehicle emissions, whilst allowing shipments to any destination in the world.

Easy and safe assembly
The patented quick connection (illustrated in green), allows the Carat S tank to be assembled without screws in only few minutes. Disassembly is possible at any time.
The first-class EPDM material used in the profile sealings (illustrated in yellow), has been laboratory tested to last more than 25 years.
The centering bolt (illustrated in orange) assures the accurate and easy assembly of the two half shells preventing any leaks
