Why should a gas concentration alarm be installed in a high vacuum oven?

The purpose of baking is to make the solvent or oil volatilize faster and improve the drying speed and surface reliability of the product. The higher the baking temperature, the faster the generation of flammable and explosive gases. Since the oven is a closed area with only a small exhaust port, if the flammable and explosive gases are not discharged quickly, they will gather in the oven to a dangerous degree. Therefore, we need to install an over concentration alarm to monitor the interior of the oven. The over concentration alarm has normally open and normally closed electric shock signals, and can output linkage control signals - control the heating function of fan or oven and drying oven. When the gas concentration exceeds the standard, it will give an alarm in time and cut off the heating power supply, and reheat after the gas concentration decreases.


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


Which ovens need gas concentration alarms?


(1) Baking ovens such as printing products and products with painted surfaces mainly show that paints and other products contain volatile organic solvents, which produce a large amount of flammable and explosive gases after baking;


(2) Oven for baking oil volatilization and other products, such as transformer, circuit board, etc;


(3) Baking glue, such as sole, glass film, etc;


In short, as long as the baked products volatilize flammable and explosive gases, the oven needs to be equipped with gas concentration alarm.
