Which is more energy-efficient, explosion-proof variable frequency motor or DC motor

The comparison of energy-saving performance between explosion-proof variable frequency motors and DC motors needs to be combined with specific application scenario analysis, basic energy consumption comparison, the particularity of explosion-proof scenarios, and application scenario recommendations. There is no absolute superiority or inferiority between the two, and efficiency, control accuracy, cost, and environmental adaptability need to be weighed according to specific needs.

What is the explosion-proof level BT4

What is the explosion-proof level BT4

BT4 is a B-class explosion-proof device, suitable for environments with common explosive gases and surface temperatures ≤ 135 ℃, but high-temperature gases (such as acetylene) should be avoided from use.

Explosion proof grades BT4 and CT4

Explosion proof grades BT4 and CT4

The main differences between explosion-proof levels BT4 and CT4 are reflected in their explosion-proof capabilities, applicable gases, and protection levels，If the work environment involves high-risk gases such as acetylene and hydrogen, or requires a high level of protection, CT4 should be selected; If only conventional gases such as methane and ethane are processed and the temperature requirements are low, BT4 can be used.
