investing in components that are unlikely to fail . This balances operational risk and inventory costs .
• Supported predictive and preventive maintenance : Align the spare bundle philosophy with predictive maintenance programs . By monitoring the condition of the heat exchanger , spares can be ordered and replaced proactively avoiding failure before they happen .
• Compliance with safety and environmental standards : Ensure that critical equipment used in hazardous or environmentally sensitive processes is promptly repaired or replaced to meet safety and environmental regulations .
• Planned maintenance flexibility : Maintenance Team can schedule tube bundle replacements during planned shutdowns when spares are readily available , improving turnaround times and allowing for better planning of maintenance windows .
• Reduced emergency situations : A welldefined spares bundle philosophy reduces the likelihood of costly emergency repairs , where expedited shipping and labour costs can increase expenses .
• Timely replacements : Having spare bundles on hand allows for the timely replacement of severely corroded bundles and facilitate the utilization of interchangeable bundles for similar equipment , thus extending the bundle service life .
