Air recycle System

Air cycle type Using two low-noise centrifugal fan, the heating room hot air were blown into the left and right side of the duct, the air flow from the bottom of the box after the two sides into the studio, and the workpiece in the studio after the heat exchange, into the upper part of the duct. Then returned to the heating chamber. So repeatedly cycle to make the temperature of the studio gradually increased. The structure of the device and the principle of hot air circulation to ensure that the temperature uniformity of the various areas of the oven, excluding the low temperature dead and blind.
Blower Motor Using heat-resistant insert type centrifugal fan

The Part of Burner Chamber

Burner Position Set on the top of the box, Behind the Heating Chamber located in burner, circulating fan on both sides

Auxiliary Function& System Protection Configuration

1.Electrical short circuit protection and over current protection, to prevent motor burn and separated.

2.Electrical and heating burner interlocks, that is to say heating after air blast.

3.Control line protection, to prevent short circuit, causing the accident.

4.Air Switch, to prevent the main return circuit overload with short circuit, causing accident.

5.Without electricity for subsequent power to prevent, Prevent continued to increase baking time caused damage to bake.

6.According National electrical industry standard for electrical components, circuit protection.
Protection of Burner

1、            Gas under-voltage protection.

2、            Air pressure switch protection.

3、            Gas leakage protection, with gas leak alarm.

4、Before the burner ignition advance purging ,Heating chamber can be residual gas emptying. 4、Ignition failure alarm. 5、After combustion flame abnormal alarm.
