Dongfeng xinjiang truck parts Post-processing insulation panel assembly 1204025-T5KF01Y

Built to optimize the aftertreatment system’s operating temperature (200-400℃), this insulation panel assembly delivers exceptional thermal insulation performance. It features a three-layer structure: an outer 0.8mm-thick aluminized steel shell (reflecting 90% of radiant heat), a middle 30mm-thick high-temperature resistant ceramic fiber core (thermal conductivity ≤0.038 W/(m·K)), and an inner heat-resistant felt layer (withstanding continuous temperatures up to 600℃). This design reduces heat loss from the aftertreatment system by 75% compared to uninsulated setups, ensuring the SCR catalyst reaches optimal working temperature faster (within 5 minutes of engine startup) and maintains efficiency during low-load operation. It also lowers the temperature of adjacent chassis components (e.g., fuel tanks, wiring harnesses) by 40-60℃, preventing heat-related damage

Designed to protect the aftertreatment system and surrounding chassis parts, the assembly integrates structural reinforcement and heat shielding functions. The aluminized steel outer shell is reinforced with transverse and longitudinal ribs (1.2mm thick), enhancing impact resistance against road debris or minor collisions—preventing dents that could compress the insulation core. The panel’s edges are folded and sealed with high-temperature silicone adhesive, blocking dust, water, and road salt from entering the insulation layer (avoiding degradation of thermal performance). Additionally, the panel acts as a heat shield, reducing the risk of fire hazards from flammable materials (e.g., leaves, oil-soaked rags) coming into contact with the hot aftertreatment housing. This dual protection extends the service life of the aftertreatment system by 30% and minimizes maintenance costs

Engineered to withstand the harsh conditions of truck operation—including extreme temperatures, road salt, and chemical contaminants—the insulation panel assembly offers long-lasting durability. The aluminized steel shell undergoes a chromate conversion coating process, passing 800-hour salt spray testing (per ASTM B117) with no rust or peeling. The ceramic fiber core is resistant to thermal shock (from -40℃ to 600℃), avoiding cracking or shrinkage after repeated heating and cooling cycles. The inner felt layer is treated with a hydrophobic coating, preventing moisture absorption that could reduce insulation efficiency or cause mold growth. This resistance ensures the panel maintains performance for over 5 years in diverse environments, from freezing northern winters to hot southern deserts, and coastal areas with high salt concentrations

Designed for efficient installation on Dongfeng Xinjiang trucks, the insulation panel assembly features a user-friendly design with precision machining. All mounting holes are drilled with a concentricity error of ≤0.1mm, ensuring perfect alignment with the aftertreatment housing’s mounting studs. The package includes 12 stainless steel M6×20 bolts, lock washers, and heat-resistant gaskets (compatible with high-temperature environments). Installation steps are straightforward: align the panel with the aftertreatment system, insert the bolts through the pre-drilled holes, and tighten to the recommended torque (15-20N·m) with a standard wrench. No specialized tools or cutting are required, and a professional technician can complete the process in 30 minutes or less. The panel’s lightweight design (only 4.8kg) reduces installation fatigue, and its modular structure allows for easy removal during aftertreatment maintenance—minimizing truck downtime for commercial operators
