FAQs
Yes. This motor carries Exdb flameproof protection and IP55, making it suitable for hazardous-area zones typical in petrochemical and oil-gas facilities. It supports safe installation with a D-End top terminator box and robust cast-iron framing to withstand demanding environments.
The unit is a 3-phase, 2-pole motor with IE4 efficiency. It operates in ambient up to 40°C at up to 1000 m altitude, with Exdb protection and IP55 ingress protection. It is designed for continuous operation in S1 duty, delivering high efficiency across full-load and partial-load conditions.
Yes. The motor supports direction of rotation on both sides, enabling flexible drive integration for equipment such as pumps and fans that require bidirectional operation in constrained spaces.
Key considerations include mounting orientation, Terminator Box Location (D-End top), and ensuring adequate ventilation for cooling. The 315 frame with cast-iron construction provides longevity under vibration and corrosive exposure typical in heavy industry; verify clearances per OEM guidelines and alignment with existing drive systems.
The combination of Exdb flameproof protection, IP55 enclosure, and IE4 efficiency yields reduced energy consumption and maintenance downtime. In hazardous facilities, this translates to lower operating costs, improved uptime, and longer intervals between maintenance cycles, supporting a favorable total cost of ownership over the motor’s lifecycle.
