Proven the most thermally efficient by far.
When you compare one reefer door against another, you start and end with one measure: how well it holds the cold. The more thermally efficient a door is, the more it can help protect your cargo, save energy and reduce your overall cost per mile.
And the fact is, only one door has proven itself the most efficient you can have so it's actually in a class by itself PolarGuard.
In an independent, head-to-head research study, the TODCO PolarGuard® reefer door proved to be 44.6% more thermally efficient than the closest competitor.
