HOT AIR CHAMBER

Each hot air chamber is design to stop all fan motors in few seconds to protect the fabric when the machine is stop. This is standard and is programmed by PLC.  Two high efficient axial fans are installed in each chamber (3-M) for smooth and high air circulation. Each motor is controlled by AC inverter drive for infinite variable speed, and the amount of hot air circulated inside the chamber can be set easily at the POD.  Adjusting the individual damper can regulate the volume of air circulated through the upper and lower nozzles in each chamber.  The velocity of airflow inside the chamber is computer control to within ±10％, and the temperature variation to within ±2°C.  Each exhaust fan is controlled by AC inverter drive for variable speed control. Optimum speed can be obtained easily by setting at the POD to cut down heat loss and reduce energy consumption.  Heat source choices can be high pressurized steam, LNG or LPG, and Thermo Oil.
