Which tool is used to remove excess heat almost instantaneously after hot-melt seaming?

The correct choice is the vacuum cooling tool, which is specifically designed to quickly and effectively remove excess heat after hot-melt seaming. This tool utilizes a vacuum mechanism to extract heat from the area where hot-melt adhesives have been applied. This rapid cooling is crucial as it helps to solidify the adhesive faster, ensuring a strong bond without compromising the materials involved in the seaming process.

Using a vacuum cooling tool significantly reduces the risk of damage to the surfaces being worked on, as it minimizes the duration of exposure to excessive heat. It is particularly important in situations where precision and temperature control are critical, especially in flooring applications where the integrity of the adhesive bond can directly impact the performance and longevity of the installation.

While other tools such as an iron or cooling fan could spread heat or assist in cooling in certain contexts, they do not provide the same efficiency or effectiveness as a vacuum cooling tool in the specific task of removing excess heat to facilitate immediate handling and installation processes. The steam roller, on the other hand, is typically used in paving and compaction tasks and is not relevant to the hot-melt seaming process.
