DIRECT ANSWERA jacket transfers heat across the vessel wall and keeps the process interior relatively clear; an internal coil puts heat-transfer surface in the process but changes cleaning, inspection and internals access. Select using duty, fouling, pressure separation, temperature response and maintenance.
Thermal-interface checklist
- Process and utility fluids with operating cases
- Heat duty, approach temperatures and controllability
- Fouling, cleaning and product contamination limits
- Pressure boundary, drains, vents and removable internals
Relevant manufacturing capability
- Drawing, datasheet and equipment-list manufacturability review
- Self-manufactured and coordinated-supply scope identification
- Technical, quality, document and delivery clarification
Key notes
- The same nominal heat-transfer area does not make jacket and coil performance or cleanability equivalent.
