Refrigerated Trailers with ThermoGuard are built to resist moisture
As refrigerated trailers age they tend to absorb moisture into the foam insulation, causing hundreds, if not thousands of pounds of weight gain over the life of the trailer. This can be a result of several conditions. A common scenario includes water intrusion due to damage to the sub-floor on the underside of the trailer, perhaps from road debris or a tire blowout, which exposes the foam to the outside environment.
Another moisture path into insulating foam can be from washing the interior of the trailer or it may come from normal interior condensation through the liner—that's right—through the liner. Traditional fiberglass (FRP) or even the newer thermoplastic liners allow moisture to permeate the liner. However, ThermoGuard includes an exclusive metallic barrier imbedded within the composite layers of its construction. This barrier not only reduces the effects of "out-gassing," but also helps seal the laminate to block moisture passing through the liner.
Moisture Resistant Advantages
ThermoGuard's ability to reduce out-gassing as well as reduce intrusion of moisture into the insulation has a number of advantages for Great Dane Customers.
• Helps maintain the trailer's thermal capacity as the trailer ages.
• Reduces operational costs by helping reduce cooling unit run-time and maintenance, and saves cooling unit fuel.
• Extends the useful life of the trailer, increasing the trailer's productivity and improving resale value.
• Resists weight gain over the life of the trailer resulting from moisture permeation through the lining.
