Proven Test

Summary


The results speak for themselves. While competitive OEMs have presented unfounded assertions to customers rebutting the efficiency claims of ThermoGuard, Great Dane has the data that shows conclusively how the exclusive glass-reinforced thermoplastic interior liner's advanced thermal properties lead to long-term efficiency and costs savings for users of refrigerated trailers.

The results speak for themselves. While competitive OEMs have presented unfounded assertions to customers rebutting the efficiency claims of ThermoGuard, Great Dane has the data that shows conclusively how the exclusive glass-reinforced thermoplastic interior liner's advanced thermal properties lead to long-term efficiency and costs savings for users of refrigerated trailers.

Available to Great Dane customers for more than six years, ThermoGuard samples were submitted by Great Dane to an independent third party laboratory that specializes in permeability testing. In these tests, ThermoGuard was evaluated against several competitive lining materials for permeability of water vapor and HFC 245fa, the blowing agent used in trailer urethane foams. These results agree with inservice test data confirming that ThermoGuard lining has the lowest permeability, protecting trailer insulation better and helping maintain performance and save fuel over the life of the vehicle.

The innovative ThermoGuard lining's barrier layer reduces "out gassing" of the polyurethane foam used in reefer trailers for insulation. This key component seals the trailer's insulation, significantly reducing the insulation degradation caused by normal aging in trailers with traditional interior linings.

With ThermoGuard, cooling units do not have to work as hard to make up for degrading insulation performance, reducing cooling unit run-time, saving fuel and refueling time, extending refrigeration unit life and lowering maintenance costs.

Great Dane's testing of in-service Classic reefers with ThermoGuard has indicated a loss of thermal efficiency comparable to just one year after more than seven years of service. In this customer operation, identically specified units without ThermoGuard exhibited rapid loss of thermal efficiency in the first two years of service and then continued to degrade over the life of the trailer. Earlier evaluations of the same
ThermoGuard equipped trailers after 6, 8 and 20 months of service indicated an almost insignificant loss.

ThermoGuard addresses the need for stiffness in a trailer's interior liner, helping to prevent the force from pallets, cargo or forklifts during loading and unloading from damaging the foam insulation in the trailer walls, causing it to lose mechanical and ultimately, thermal integrity. The inherent stiffness comes from the high-glass content in ThermoGuard and its placement in the glass-reinforced, thermoplastic liners. With more glass than any other product on the market, and a design that orients the glass close to but not too near the surface, this unique liner combines significantly better strength and increased stiffness as compared to similar thickness or thinner liners. In addition, the liner remains resilient, so impacts from loading equipment are less likely to puncture or tear the material leading to trailer maintenance or insulation degradation.

Adhesion characteristics are also addressed in the design of ThermoGuard. The proprietary and unique adhesion system creates a specialized layer that serves as a highly effective anchor into the foam insulation. This very strong mechanical bond helps protect against de-lamination caused by gouging, rubbing or denting that can damage the foam attached to the liner and cause the liner to separate from the insulation inside the trailer's walls.

As tests indicate, ThermoGuard extends a refrigerated trailer's useful life by performing extraordinarily well for Great Dane customers over longer periods of time. In all areas, this revolutionary liner is proving to be superior to all other options currently available on the market.
