The Aspire Ce5-S BDC (bottom dual coil) atomiser is a unique design with a new heating element coil technology. As bottom coil clearomizer types are becoming popular, the Aspire Ce5-S BDC tank is reinforced with an aluminum shield with a visible clear  tube and holds approximately 1.8ml of liquid capacity.

The tank can be disassembled into four total parts for easy cleaning and maintenance. Coil heads can be easily replaced by unscrewing the bottom end cap.
