Differences and advantages of gas infrared ovens vs. air ovens in powder coating equipment

In powder coating equipment, ovens are an essential part of the process. 

There are two main types of ovens commonly available in the market, one is gas infrared oven and the other is air oven. 

These two types of ovens have their own advantages and disadvantages in the process of use, and this article will introduce their differences and advantages.

1. Gas Infrared Ovens

Gas infrared oven is a type of oven that uses gas as the heat source and is heated by gas infrared radiation. 

1. This kind of oven can provide high temperature and quick heating, which can quickly heat the surface of the workpiece to a certain temperature. 

2. Also, because the heat generated by burning gas is transferred through infrared radiation, it can heat the surface of the workpiece more evenly, resulting in a smoother coating. 

3. In addition, gas infrared ovens are energy efficient, as they are less costly than other traditional heat sources, and they reduce energy waste.

However, there are some drawbacks to gas infrared ovens. 

First, gas ovens heat up quickly, but they also cool down just as quickly. This requires that after heating, the workpiece must be moved quickly to the next process or the quality of the coating will be compromised. 

In addition, gas ovens consume large amounts of oxygen and therefore require adequate ventilation systems.

2. Air Ovens

An air oven is an oven that uses diesel or gas to heat air and heats the surface of the workpiece by circulating the air. 

The advantage of this type of oven is that it heats evenly and can heat the surface of the workpiece to a certain temperature. At the same time, because it is heated by air, there are no pollutants from gas combustion and no pollution to the environment. In addition, air ovens have better temperature control and can be adjusted according to the process requirements.

However, air ovens also have some disadvantages. 

First, air ovens are slow to heat and take a long time to heat the surface of the workpiece to a certain temperature. This results in a relatively inefficient process, requiring longer heating times to complete the curing of the coating. Second, because the air oven uses air heating, it requires air circulation during the heating process and therefore requires a larger volume than a gas infrared oven, as well as a stronger ventilation system.

3. Comparison of Advantages and Disadvantages

When choosing between gas infrared ovens and air ovens, the decision needs to be based on process requirements and production flow. If fast heating speed, low energy consumption and uniform heating are required, then gas infrared ovens are a good choice. If you need high precision in heating temperature control, but also need environmental protection and good safety performance, then air ovens are a better choice.

In addition, the size and number of ovens needs to be determined by the specific production scenario. If the production process requires a large number of heated workpieces, then a gas infrared oven may be more suitable because it can do the heating faster. If the production process requires fine control of the workpiece, then an air oven may be a better fit.

Finally, whichever type of oven is chosen, it needs to be properly regulated and managed according to the process requirements and equipment characteristics to ensure the stability of the production process and the quality of the coating.

Conclusion

In summary, both gas infrared ovens and air ovens have their own advantages and disadvantages and need to be selected based on specific production requirements. 

Regardless of which type of oven is used, the normal operation of the equipment needs to be ensured and the daily maintenance and management of the equipment needs to be done well to ensure production efficiency and coating quality.
