CO2 engineered tanks can be with polyurethane or vacuum & perlite insulated. Both types are good for long-term storage of cold liquids, utilizing a high performance heat insulation enabling low evaporation rates and can either be 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 Engineered tanks
 
The CO2 Engineered tanks are designed for long-term storage of liquefied carbon dioxide. Engineered tanks 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 CO2 engineered tanks are tailor made according to customer requirements.  
 
The tank capacities range between 60 tons and 300 tons with maximum allowable working pressure up to 24 bars. Engineered tanks can be supplied with ambient type of vaporizers, pipelines and other cryogenic components for a complete installation. The conventionally insulated vessels are equipped with safety valves, heaters, load-cell, weighing systems and refrigeration units, condensing the boil off gas originated from heat accumulation. The tanks are equipped with dual relief valves to prevent the possibility of excess pressure risk. Although CO2 Engineered Tanks are based on a standard design, they can be customized as per specific application and requirements. The tanks are designed according to Directive 97/23/EC, using the standards AD 2000M and EN 13458. Engineered tanks according to ASME are also provided.
 
Vacuum Insulated Engineered tanks
 
The cryogenic design of CO2 engineered tanks combines safe, flexible and economical operation with their high quality perlite vacuum insulation. Karbonsan CO2 Engineered Tanks are supplied complete with all pipework, a 3-way diverter with dual relief system, liquid level indicator, pressure gauge, automatic pressure build up and pressure reducing systems allowing fast and easy installation on site.
 
Engineered tanks can be supplied with ambient type of vaporizers, pipelines and other cryogenic components for a complete installation. The tanks are insulated with a proved high quality vacuum-perlite system with molecular sieve adsorber. Although CO2 Engineered Tanks are based on a standard design, they can be customized as per specific application and requirements. The tanks are designed according to Directive 97/23/EC, using the standards AD 2000M and EN 13458. Engineered tanks according to ASME are also provided.
