1. Explosion-proof type is explosion-proof and increased safety composite structure, the electrical component cavity is explosion- proof type, and the wiring cavity is increased safety type.

2. The product control unit and wiring unit housing are cast aluminum alloy ZL102. It adopts one-time die-casting process, the surface is smooth, the appearance is beautiful and generous, the internal density of metal is high, no bubbles, blisters and other defects, strong impact resistance, good explosion-proof performance, and the permanent “Ex” explosion-proof mark on the product.

3. After the surface of the shell is processed by high-speed shot blasting and other series of processes, the advanced automatic high-pressure electrostatic spray and heat-curing line technology is adopted. The plastic layer formed on the surface of the shell has strong adhesion and is not easy to fall off, effectively achieving the purpose of protecting the shell. Improve the anti-corrosion ability of the product.

4. Steel heat sink is made by special process welding, with special heat transfer oil inside, no loss, no volatile, no pollution, no noise, high thermal efficiency.

5. The heating area is large, the heat dissipation is even, and the power selection is divided into three files, which can be selected acc- ording to the needs.

6. Configure the thermostat and overheat protection system to automatically adjust the indoor temperature to prevent overheating.

7. The base is equipped with casters for easy movement.

8. All exposed fasteners are made of stainless steel.

1. According to the model implication's rules to select regularly, and Ex-mark should be added behind model implication;

2. If there are some special requirements, it should be pointed as ordering.
