| 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. |

thermal resistance temperature sensing element |
| Draught Fan Control | Frequency Control |
| 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. 5, Ignition failure alarm. 6, After combustion flame abnormal alarm. |
PTFE natural gas furnaces are employed in a wide range of
industries, including:
- Aerospace: Production of seals, gaskets, and other components for
aircraft and spacecraft.
- Automotive: Manufacturing of seals, bearings, and other parts for
vehicles.
- Chemical processing: Lining of pipes, valves, and tanks to resist
corrosive chemicals.
- Electronics: Production of electrical insulation, capacitors, and
printed circuit boards.
- Medical: Fabrication of medical devices, implants, and surgical
instruments.
Using PTFE natural gas furnaces offers several benefits:
- Precise temperature control: Ensures optimal processing conditions
for PTFE materials.
- Uniform heating: Provides consistent heating throughout the furnace
chamber.
- High efficiency: Natural gas fuel provides a cost-effective and
environmentally friendly heat source.
- Safety: Advanced safety features minimize the risk of accidents and
ensure operator safety.
