This white paper is intended primarily for designers/engineers who are dealing with vibration tubing failure-related issues during product design and wish to understand how header failure on the outdoor coils of a packaged rooftop unit can be minimized. The scope of this document is to help designers/engineers know of the best practice for designing a header on the outdoor or indoor coil. This document showcases the stress levels that the feeder tubes on the header experience while the unit is in transit, and how redesigning the feeder tubes can help the safe transit of packaged rooftops.
