The Caldera RDA is VOLCANO’s signature rebuildable atomizer completely designed, engineered and built in Hawaii. Machined from superior-grade 303 stainless steel for a solid foundation for the three post rebuildable atomizer. Unrivalled engineering, research and design of every component of the CALDERA RDA makes for a superb rebuildable.


The CALDERA is VOLCANO’s pioneering rebuildable dripping atomizer with a revolutionary design as culmination of years of research and development. It has been completely designed, engineered and built in Hawaii, USA.

Machined out of 303 stainless steel, quality and resilience were the top priority in the Caldera build. The three-post design facilitates ease of coil building no matter what size or type of wire is used, with slotted post holes to ensure secure contact points for build leads. The positive centre copper contact allows for maximum electrical conductivity along with better resistance control for any coil build.

Tirelessly tested throughout its many developmental stages, the final structure of the CALDERA is the perfect balance of refinement and function. A stainless steel wide bore drip tip further increases the amount of air that can be pulled through the atomiser. The spiral design of the CALDERA’s cap evokes the form of a cinder cone volcano and is both stunning and functional.

The layered spiral form allows any condensation forming inside the atomiser to fall back onto the coil so no e-liquid is wasted during vaping. The cap also allows control over the airflow into the chamber with a simple twist open or close, to ensure the perfect stream of air.
