Carbon dioxide tanks (micro bulk tanks) are cryogenic vessels for storage, transportation and gasification of liquid carbon dioxide.
Carbon dioxide tanks (micro bulk tanks) automatically maintain required pressure of the vessel by controlled liquid evaporation. The source of energy for creating pressure and evaporation of the liquid is the ambient temperature.
The carbon dioxide tank (micro bulk tank) includes a vessel for cryogenic liquids, pipelines, an external atmospheric evaporator and an external pressure regulator. The carbon dioxide tank (micro bulk tank) consists of a high-pressure vessel placed inside the casing. The space between the pressure vessel and the outer casing is evacuated and filled with micro glass fiber insulation, which is covered with aluminum foil to protect against thermal radiation. The inner pressure vessel and vacuum casing are made of stainless steel.
The piping system ensures filling the tank (micro bulk) with gas and maintaining the pressure stated in the specification. The piping system is also made of stainless steel. Stop valves, safety valves and fittings are made of stainless steel.
The instrumental part of the tank consists of a pressure sensor and a differential pressure sensor, providing a complete system monitoring. The differential pressure gauge provides highly accurate readings of the tank (micro bulk) pressure status. The carbon dioxide tank automatically maintains the required pressure of the vessel by controlled evaporation of the liquid. The source of energy for creating pressure and evaporation of the liquid is the ambient temperature. The pressure coil is fixed to the outer casing. The evaporator is fixed on the product pallet.
They can be additionally equipped with an atmospheric mounted evaporator to increase productivity.
