Humid air in the head space is replaced by high purity, inert and totally
dry nitrogen. A precise valve control system ensures that as the tank is
filled or emptied, the nitrogen content is automatically compensated to
maintain the protective blanket.
The result is safety, reliability
and protection from degradation through oxidation.
For vessels
often used in batch processes, characterized by cyclic filling and emptying,
we have developed special inert gas sluices which prevent the entry of
oxygen effectively.
