CO2 stationary tanks can be polyurethane insulated or cryogenic. Both types are good for long-term storage of liquid carbon dioxide, utilizing a high performance heat insulation enabling low evaporation rates and can be either vertical or horizontal.

CO2 Storage Tank production is one of our core businesses. Karbonsan has continuously produced the most innovative, reliable and efficient CO2 tanks in the market, including horizontal CO2 tanks and vertical CO2 tanks in various sizes to meet any facility’s CO2 requirements. Whether PUR insulated or a vacuum-insulated unit, the established quality of Karbonsan industrial equipment is distinguished.
 
PUR Insulated CO2 Storage Tanks
 
These tanks are designed to operate efficiently even in the environments of high heat and humidity to store liquefied carbon dioxide and are available in vertical or horizontal arrangement with a conventional PUR insulating material. The sealed cladding is made from aluminium which protects the insulation against mechanical damage and any moisture penetrating into the insulation. The horizontal tanks are technically more practical to interfere and vertical tanks are more convenient when there is a limited space for installation at site. PUR Insulated CO2 Storage Tanks are the most economical way to store CO2.
 
Karbonsan liquid CO2 tanks are available in nominal capacities of 3 tons to 300 tons with maximum allowable working pressure up to 24 bars. The PUR insulated CO2 Stationary Tanks offer minimal maintenance, efficient operation in heat and humidity, manway for inspection and cleaning, evaporator coil inside the vessel, safety valves, heaters, optional load-cell, weighing systems and refrigeration unit, condensing the boil off gas originated from heat accumulation. They can be supplied with ambient type of vaporizers, pipelines and other components for a cylinder filling station as well as for other bulk use purposes. The tanks are equipped with the dual relief valves to prevent the possibility of excess pressure risk. Although PUR insulated CO2 Stationary Tanks are based on a standard design, they can be customized as per specific application and requirements.
 
Vacuum Insulated CO2 Tanks
 
The cryogenic design of CO2 stationary tanks combines safe, flexible and economical operation with their high quality perlite vacuum insulation and they are available in vertical or horizontal arrangement. Karbonsan cryogenic CO2 stationary tanks are supplied in complete with all pipe work; a 3-way diverter with dual relief valves, liquid level indicator, pressure gauge, automatic pressure build up and pressure reducing systems allowing fast and easy installation on site.
Special connections are included to Cryogenic CO2 stationary tanks to allow easy installation of ancillary equipment such as vaporizers, cylinder filling systems, transfer pumps and dry ice machines. Vacuum insulated tanks include automatic pressure build up and pressure reducing systems.
 
The tanks are insulated with a proved high quality vacuum-perlite system with molecular sieve adsorber. Although cryogenic CO2 Tanks are based on a standard design, they can be customized as per specific application and requirements. The bulk tanks are designed according to EC Directive PED 97/23/EC, using the standards AD 2000 or EN 13458. Section VII, Division 1 of the ASME Code and other national pressure vessel codes are also provided as required.
