Why do industrial ovens contain gas concentration alarms?

2019-04-04   

The purpose of baking is to allow the solvent or oil to evaporate more quickly, and to improve the drying speed and surface reliability of the product. The higher the baking temperature, the faster the flammable and explosive gases are produced. Since the oven is a closed area, there is only a small exhaust port. If the inflammable and explosive gas is not quickly discharged, it will accumulate inside the oven to a dangerous level. Therefore, we need to install an ultra-concentration alarm. Monitor the inside of the oven. The super-concentration alarm has a normally open and normally closed electric shock signal, and can output a linkage control signal--control fan or oven, drying box heating function, etc., when the gas concentration exceeds the standard, an alarm is issued and the heating power is cut off, and the gas concentration is lowered. Then reheat it.

The oven gas concentration alarm adopts imported sensor, which has the characteristics of high precision, accurate measurement, anti-poisoning, stable performance and probe explosion-proof structure design. It is suitable for various dangerous places such as factories, and is convenient to connect with various PLCs and other systems. Degree of protection.

Which ovens need to be equipped with a gas concentration alarm?

(1) Ovens for baking printed products and surface painting products, mainly characterized by the presence of volatile organic solvents such as paints, and a large amount of flammable and explosive gases after baking;

(2) Ovens for baking oil volatile products, such as transformers, circuit boards, etc.;

(3) baking glue such as: sole, glass film, etc.;

In short, as long as the baked product evaporates the flammable and explosive gas oven, a gas concentration alarm is required.
