A CO2 bulk tank typically feeds a microbulk Co2 tank. Bulk CO2 tanks can range from 3 to 50 tons. Both tanks are typically also cryogenic tanks that are designed to keep the cryogenic fluid cold so that it does not vent off and waste the cryogenic liquid. In contrast, a micro bulk CO2 tank will typically range from a half a ton to a ton and are typically not refrigerated. Micro bulk tanks are typically filled periodically by beverage CO2 Supply trucks or they can be installed in a CO2 system that is supplied from a bulk tank.
