CCTHERM Caveats
• Design mode only provides the starting point.• Always inspect vibration results carefully.• Verify calculated tube count.• Some TEMA configurations require careful
review of results.

CCTHERM Summary
• CCTHERM provides conservative and accurate heat exchanger design and rating.
• CCTHERM is much more than heat exchanger design and rating software. It is a powerful simulation tool, integrated into the system flow sheet.
