1. Safety performance: Explosion-proof heater has explosion-proof function and can work in flammable and explosive environment with higher safety performance. Its design after special treatment, such as the use of explosion-proof motor, can be used safely in high temperature, high pressure and even flammable and explosive environment.

2. Use of the environment: explosion-proof heater for flammable and explosive places, any ignition source or overheating equipment may cause an explosion or fire, therefore, explosion-proof heater is essential equipment.

3. Price: Due to the explosion-proof  heater's special material and process of manufacturing, its cost is usually higher than that of the ordinary heater, so the selling price is also relatively high. However, considering its advantages in terms of safety performance and use of the environment, its price is relatively reasonable. The price of ordinary heaters is relatively low, but the use of safety issues need to pay attention to.
