Elanco's unique double walled tube technology has a purge passage coiled through the middle of the tubes wall. The double walled tube design should be used when the exchanger is part of a critical equipment design or safety is of the utmost importance. Applications for Elanco's double walled tube heat exchangers can be as follows:
1. When Process and Cooling sides react violently. For example - Sodium and Water, SO2
2. When an exchanger tube failure would incur expensive downtime in critical processes.
3. When an exchanger tube failure would seriously damage expensive equipment. An oil cooler on a gas turbine.
Elanco can manufacture double walled tube exchangers with several combinations of tube material and configurations of process and cooling/heating flow. Exchangers can be designed and manufactured to ASME Section VIII Division 1 Code.
