Thermo King Barrier Back Channel Return-Air Assembly 929115
Official OEM Thermo King parts catalog entry for the Barrier Back Channel 929115, verified by PEAK Thermo King and West Texas Thermo King Texas, Utah, Wyoming, Washington, Oregon, serving all of the USA.
Built for Performance: The Thermo King Barrier Back Channel 929115 supports precise airflow management and compartment isolation for Thermo King refrigeration unit installations. This OEM-grade barrier improves return-air routing and structural integration to protect temperature control integrity across transport refrigeration applications.
Thermo King refrigeration system components demand reliability. The Barrier Back Channel 929115 enhances uptime for refrigerated trucks and reefer trailers by maintaining a stable air path behind evaporator assemblies and limiting unwanted thermal exchange.
- Structural Air Channel – Guides return air behind the evaporator assembly to maintain consistent temperature control and reduce airflow disturbances.
- OEM-Compatible Design – Aligns with Thermo King installation interfaces to ensure secure fitment and simplify field service procedures.
- Durable Construction – Engineered to withstand typical transport refrigeration environments for long service intervals and dependable fleet operation.
- Thermal Isolation – Reduces heat ingress and condensation risk at the unit interface to protect cargo quality and refrigeration efficiency.
- Serviceability – Facilitates access for scheduled inspections and maintenance without compromising the return-air path.
- Fleet Uptime Focus – Supports quicker diagnosis and replacement workflows to minimize vehicle downtime and operating cost.
Product Details
| Part Number | 929115 |
| Product | Thermo King Barrier Back Channel |
| Application | Return-air and barrier assembly for Thermo King refrigeration unit installations on refrigerated trucks and reefer trailers |
