Thin-film evaporators Maintenance

The equipment used in radiochemical plants is, for the most part, similar to that found in other industrial chemical plants. The equipment should be selected for minimum holdup, thus reducing shielding requirements and criticality hazards. For example, thin film evaporators, operating continuously, should be selected instead of pot-type vessels. The method of coupling equipment together and the remote control and handling features of equipment design may be quite different, especially for the remote-maintenance type of plant. 

Maintenance Because thin-film evaporators are "rotating machinery," they are precision machines and preventative and corrective maintenance are important consideration. Bearings and mechanicai seais must be properiy appiied and maintained. Properly maintained, thin-film evaporators provide long, trouble-free service. Premature failure can be caused by ...
