Also known as ton tanks, drum tank size and capacity depends on exact drum specification and product density.

Drum tanks are a commonly used in supply package for a wide range of low to medium pressure packaged gases. Most common products are packaged chemicals (e.g. ammonia, hydrogen chloride, sulphur dioxide, ethylene oxide, hydrocarbons) and refrigerants (e.g. R22, R134a, R404A).

Drum tanks meet the needs of customers whose demand is too high to be easily managed via cylinder supply, but not high enough to be suitable for delivery in bulk/ISO tanks.

The drum tanks provide advantages of minimising the need for cylinder handling, in changeovers and site transport, as well as minimising space requirements.
