● With heating elements at four sides of inner wall, heating is instantly achieved at uniform level.
● Heating elements is installed in the walls, which prevents generation of corrosive gas and contacts with water vapor, to ensure longer life.
● Microprocessor PID auto-tuning controller with digital setting and display.
● Since the air circulates between twin-fold wall structure, this air circulating system cools temperature of outer case.
● Heating cabinet is separated from control box by heat resistant panel to protect the electronic controller.
