Low Temperature Reactors

Certain processes are increasingly operated at low temperatures down to –100°C in order to achieve high selectivity in reactions or separation processes, for example in polymerizations reactors for rubber production or crystallizers for the separation of isomer mixtures. In such cases low temperature mechanical seals are used for sealing the agitator shaft. Their structural design, materials, elastomeres, lubricants and supply units have been specifically designed for these extreme conditions so that high operational safety can still be achieved and costly shutdowns are avoided during procedures that primarily consists of continuous operation.
