Import Air Duct Heater — Buy in wholesale FOB from Supplier in China

Sinton's air duct heater is an inline electric resistance heater designed for integration into forced-air duct systems across low, medium, and high temperature ranges. The source specifies three temperature classes: low temperature to 160 °C, medium temperature to 260 °C, and high temperature to 850 °C. An overheat protector is housed in the terminal box, and the outer sheath is stainless steel constructed to reduce heating element vibration under airflow. Maximum allowable air pressure through the duct is stated at 0.3丝巾/cm², above which recirculation duct heaters are recommended instead.

The heating elements are sheathed in stainless steel, a standard material for corrosion resistance and mechanical durability in process air heating. The three-tier temperature classification aligns with common industry groupings: low temperature for comfort heating and drying, medium for process air and coating curing, and high for calcination, metal treatment, or chemical reactor preheat applications. The overheat protector in the terminal box is typically a bimetallic thermostat or thermocouple-linked contactor set to interrupt power when element surface or outlet air temperature exceeds safe limits. Vibration reduction through sheath design is important in aerospace and defence applications where element fatigue could cause failure.

Primary buyers operate in aerospace, ordnance, chemical processing, and higher-education research laboratories. These users require controlled, rapid air temperature rise with safety interlocks and minimal contaminant emission from heater materials. When sourcing from Sinton, confirm the exact kW rating, voltage, phase, and airflow capacity for your duty point, as well as the control philosophy (on-off, PID, or SCR phase-angle).
