Middle East offshore platforms and coastal petrochemical projects are exposed to extreme working conditions all year round. The highly humid and salt-spray-heavy marine climate, combined with the unique desert dust of the Middle East, imposes rigorous requirements on the mechanical enclosures and internal electronic components of automation equipment. In hazardous areas with potential flammable gases, sealing failure or corrosion of valve control equipment can lead not only to system downtime but also to severe explosion safety incidents.
Conventional Exd products often suffer from the recurring illness of low protection grade and poor performance. To continuously resist the intrusion of fine dust and high-pressure seawater erosion, engineers must focus on the enclosure design technology during equipment sizing.
In industrial applications, it is recommended to select explosion-proof electric actuators made with a round seam allowance to match up the flameproof joint, which makes the performance of Exd better and more reliable. Combined with this structural design, the equipment must strictly meet the protection grade IP68 to maintain the integrity of the explosion-proof cavity under severe external physical erosion.
In addition to strong external physical defense, moisture control within the internal electrical cavity is equally critical. In marine environments with day-to-night transitions, temperature differences easily generate condensation inside the equipment, which can lead to electrical short circuits.
The electrical cavity of professional explosion-proof electric actuators can be equipped with a PTC electronic heating component to prevent electronic components from damage resulting from condensation. Unlike conventional designs, the heater will operate continuously and is always electriferous no matter when the actuator works or not, thereby keeping the internal cavity dry at all times.
Dynamic Corporation Limited, established in 2001, specializes in the R&D and production of electric actuators, electric valves, and their automatic control systems. In the ocean shipping and offshore industry, DCL electric actuators have become the first choice due to their small size, light weight, salt spray resistance, humidity and heat resistance, and reliable quality of stable operation for more than 20 years. Its full range of explosion-proof products has obtained multiple international certifications such as ATEX, IECEx, and CSA, providing solid guarantees for fluid automation control in severe working conditions worldwide.
