HK Series Control Switches

◆ This explosion-proof control stations are made of Copper-free Aluminium Alloy, can ensure safety by containing internal explosions and isolating the external hazardous atmosphere.
◆ The explosion proof enclosures treated with anti-static coating and all fasteners are anti-loosening.
◆The layout of buttons, switches, and other componentson of the explosion-proof control panel is rational and straightforward,ensuring ease of use and quick mastery.
◆The control methods of ex control station can be selected based on actual needs, such as manual control, automatic control, or remote control, catering to varying application scenarios.

Q1: What does “Explosion-proof” mean for an explosion-proof control station?
- A: It signifies the device’s ability to prevent the ignition of a surrounding explosive atmosphere by containing internal sparks or limiting energy levels.
Q2: In which industries are explosion-proof operator stations primarily used?
- A: They are used in environments with flammable gases or dusts, such as oil & gas platforms, refineries, chemical plants, and food processing facilities.
Q3: Can we open the operator station ourselves for maintenance?
- A: No. Only specially trained and authorized personnel may open Ex control stations in confirmed safe areas to maintain explosion-proof integrity.
