If the materials processed by the decanter centrifuge contain flammable and explosive substances such as organic solvents, the centrifuge should have explosion-proof performance. The explosion-proof performance is determined according to the explosion-proof requirements of the process. The explosion-proof occasions involved in the past have only been proposed to be equipped with explosion-proof motors. In the past two years, most of the occasions where the processed materials contain organic solvents such as solvents have been required by nitrogen protection. In fact, to realize the explosion-proof in the true sense, centrifuges must take various measures in mechanical, electrical control, accessory configuration and other aspects.
For instance: electric control system: explosion-proof isolation barrier, non-contact energy consumption braking system, electrostatic grounding, automatic control of explosion-proof.
Mechanical system: explosion-proof motor, explosion-proof lighting, anti-collision measures, anti-static transmission belt.
Explosion-proof accessories: nitrogen protection device, nitrogen online detection, on-site explosion-proof control button.
GN Explosion proof electrical control panels or electrical control stations are used in hazardous Location. The Ex control panel is designed and built to operate in environments where concentrations of flammable gases, vapors, liquids or combustible particles pose risks of ignition and explosion. GN Solids Control provide explosion proof control panel with ATEX approval, IECEX Approval, China National explosion proof approval. The protection degree is up to IP65 for weather and dust proof.
GN explosion proof control panel enclosures are cast from heavy duty aluminum so that they cannot create a spark that could possibly ignite the vapors in a hazardous location. These heavy duty panels come with seals keep explosive fumes from entering the control panel. Moreover the GN explosion proof control panels are designed to contain an internal explosion without igniting the explosive vapors present in the hazardous area to make sure it is safe for the hazardous Zone 1 or Zone 2 areas.
GN Explosion Proof Pressurized Control Panel is popular used for VFD controland soft starter of motor, especially in high temperature ambient. The explosion proof pressurized control panel consists of main cavity and auxiliary cavity. The main cavity is pressurized cavity which includes electrical components, pressure check sensor system, ventilation air distribution system, and air conditioning system. The purging system works automatically to maintain a certain positive pressure inside the main cavity.
GN Solids Control is capable to provide you with IEC Ex, ATEX or CNEx Standard Positive Pressurized Control Panel control panels with Zone 1 or Zone 2 for hazardous locations. This will also suit the North America Class I Division 1 or Division 2 hazardous locations application.
