PTFEis a popular material in the manufacturing of natural gas
furnaces due to several advantages it offers:
- Chemical Resistance: PTFE is highly resistant to chemicals, making
it ideal for use in natural gas furnaces where it may come in
contact with various gases and substances.
- High Temperature Resistance: PTFE can withstand high temperatures
without degrading, which is crucial for the efficient operation of
a natural gas furnace.
- Low Friction: PTFE has a very low coefficient of friction, which
can help in reducing wear and tear on moving parts within the
furnace.
- Non-Stick Properties: PTFE is non-stick, making it easy to clean
and maintain the furnace, and preventing buildup of residues that
can affect performance.
- Electrical Insulation: PTFE is an excellent electrical insulator,
which can be important for safety in natural gas furnaces.
- Weather Resistance: PTFE is resistant to weathering and UV
radiation, making it suitable for outdoor natural gas furnaces.
- Durability: PTFE is a durable material that can withstand harsh
conditions, ensuring a longer lifespan for the furnace.

| 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. |
