Versilon™ Polar

Carbon Dioxide Transfer Hose

Versilon™ Polar hose by Saint-Gobain overcomes the problems caused by misapplication of rubber hoses used in earlier carbon dioxide (CO2) transfer applications. Typically, these were rubber hoses designed for hydraulic uses. They were not resistant to deterioration caused when rubber comes in contact with carbon dioxide. They had reinforcing braids and fittings made from carbon steel, which were susceptible to corrosion from carbonic acid that forms when CO2 combines with moisture. They tended to crack due to the cold temperatures associated with CO2 transfer and could become stiff, brittle and hard to handle.

Later attempts to use stainless steel cryogenic transfer hoses avoided some of these problems. Metal hose remained flexible in the cold but was much heavier and harder to handle. In addition, corrugations inside metal hose can trap solid CO2 ice, causing plugging of hose, valves and pipes during CO2 transfer.
