Industrial heat curtains typically consist of four parts: a heating system, a fan system, a housing, and a control system. The heating system usually uses electric heating elements or oil/gas heaters to heat air to a set temperature using electrical or chemical energy. The fan system uses centrifugal or axial fans to generate high-speed airflow, blowing the heated air out in a laminar flow. The housing is made of metal (such as stainless steel or galvanized sheet) to ensure durability. The control system can adjust temperature, fan speed, and start/stop times to achieve automated operation. Some high-end models are also equipped with a negative pressure design, which further enhances the insulation effect through reverse airflow.
