Value Inside And Out


Great Dane's high performance PunctureGuard lining and insulating methods are making Everest reefers the industry's most thermally efficient and durable refrigerated trailers

The proof is in the test results – Great Dane's unique PunctureGuard lining for Everest refrigerated trailer models outperforms other options in the key areas of puncture, impact and peel strength, and weight savings.

PunctureGuard has up to 50 percent more impact resistence.
In comprehensive tests measuring strength, PunctureGuard was found to be one-fourth to one-third stronger than competitive products. Other tests measuring impact resistance revealed it has up to 50 percent more impact resistance. These characteristics are important for ensuring that force from pallets, cargo or forklifts during loading and unloading operations does not damage the liner, reducing the likelihood of damage to the foam insulation in the trailer walls which can lead to a loss of thermal integrity.

The inherent strength of PunctureGuard comes from the high glass content 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 has significant stiffness. In addition, the thermoplastic liner remains pliant over time, so impacts from load- ing equipment will not cause the material to curl away from walls.

PunctureGuard exhibits up to three times the peel strength of competing products.
The lining's adhesion characteristics are the result of a proprietary, unique and highly effective anchor into the foam insulation. This strong mechanical bond helps protect against delamination caused by gouging, rubbing or denting that can damage the foam behind the liner and cause the liner to separate from the insulation inside the trailer's walls.

At .070 inches, PunctureGuard is incredibly thin and considerably lighter than plywood and traditional FRP linings. Potential savings compared to traditional liners can add up to 200 lbs per trailer.

While PunctureGuard protects a reefer's insulation, the process Great Dane employs for panel foaming helps ensures Everest refrigerated trailer models deliver maximum thermal performance
for the long haul. At Great Dane's Statesboro, Georgia; Wayne, Nebraska, and Brazil, Indiana plants, reefer walls, floors and roofs are insulated using an In-Situ Panel Foaming Process, a technology that also represents a major investment by Great Dane.

Great Dane's foaming process achieves consistent insulation thickness by using advanced control technology critical to maintaining manufacturing parameters. These include tempera- tures, mix ratios, pressures and foam metering during application. The result is a void-free panel of unmatched consistency for each customer's specified insulation thickness; in other words, consistent thermal performance throughout each panel.

Great Dane's In-Situ Panel Foaming Process ensures consistent thermal performance.
The In-Situ Panel Foaming Process also enhances liner adhesion. Consistently flat, smooth linings backed by equally consistent insulating foam not only results in better thermal performance. This advanced system also creates a more aesthetic trailer with flat, smooth interior walls that are less susceptible to damage during loading and unloading operations.

Great Dane reefer manufacturing plants are using the Panel Foaming Process and panel presses to manufacture entire side and front walls, floors and roofs for Everest refrigerated trailers. The fully insulated components are then assembled using modular con- struction processes.

As the industry's leading producer of refrigerated trailers, for more than 60 years Great Dane has been a pioneer in the devel- opment of unique and advanced technologies. Reefer insulating and construction methods are now producing smoother, more consistent reefer walls, floors and roofs, providing better thermal effi- ciency and creating longer lasting refrigerated trailers that help customers lower their cost of ownership.
