AHU Casing Leakage & Thermal Bridging

Small casing defects can create big HVAC performance losses

Air Handling Unit casing is not just an outer box. It directly affects airflow, cooling performance, fan energy, condensation control, and system reliability.

Main Problems

Air Leakage• Air escapes through panel joints, access doors, gaskets, and service openings• Delivered airflow reduces• Fan may need to work harder• Dust can bypass filters• Room pressurization can become unstable (AHU Casing Leakage & Thermal Bridging)
