In the field of industrial production, explosion-proof rating is one of the important indicators to evaluate and ensure the safe operation of equipment in dangerous environments. BT4 and CT4 are two common explosion-proof classes that are critical to ensuring the safety of equipment in explosive gas environments. Let's discuss the relevant content of these two explosion-proof levels:

BT4 explosion-proof rating:

The BT4 explosion-proof rating refers to one of the levels of equipment's ability to operate safely in explosive gas environments. Where B indicates the explosive gas environment and T indicates the temperature category.

BT4 grade equipment is suitable for explosive gas environments with temperature category T4, that is, the ambient temperature does not exceed 120 degrees Celsius. After strict explosion-proof design and testing, these devices have high explosion-proof ability, and can operate safely in dangerous environments to ensure the safety of the production process.

CT4 Explosion-proof rating:

The CT4 explosion-proof rating is also one of the ability levels for equipment to operate safely in explosive gas environments. Where C represents the explosive gas environment and T represents the temperature category.

CT4 grade equipment is suitable for explosive gas environments with temperature category T4, that is, the ambient temperature does not exceed 120 degrees Celsius. Compared with BT4, CT4 grade equipment is usually used for different types of explosive gas environments, but its explosion-proof ability and safety performance are also strictly guaranteed.

To sum up, it is important to know the explosion-proof levels BT4 and CT4 for ensuring the safe operation of equipment in an explosive gas environment. In the industrial production process, we will choose the equipment that meets the corresponding explosion-proof grade requirements according to the specific working environment and requirements, and strictly abide by the relevant safety standards and norms to ensure the safety and stability of the production process.
