Why Conventional ESP Power Supplies Fail in India
Indian steel mills operate in some of the most unforgiving environments on the planet. Standard air-cooled power supplies placed directly on ESP roofs frequently experience premature failures due to several critical factors:
Conductive Metallic Dust
Sinter and blast furnace dust contains conductive iron oxide particles. Traditional air-cooled enclosures draw this dust inside, leading to catastrophic short circuits in high-voltage boards.
Extreme Ambient Heat
Summer ambient temperatures exceeding 45°C, compounded by radiant process heat on ESP roofs, cause standard electronics to overheat, de-rate, or shut down completely.
High Maintenance Hazard
ESP roofs are hard to reach, hot, and dangerous. Performing regular maintenance or replacing filters in these locations increases downtime and raises safety risks for crew.
Relocate Power Supplies Away from the Danger Zone
With SEID's remote mounting capability, you no longer need to place sensitive control cabinets on the hot, dusty ESP roof. ModuPower can be installed up to 100 meters away in a clean, air-conditioned electrical room.
- Safe, ground-level maintenance in a clean environment
- Complete isolation from roof-level heat and vibrations
- High-voltage coaxial cable maintains power efficiency without signal drop
Sealed IP65 Enclosure for Zero Dust Ingress
Our Liquid Cooled (LC) option eliminates fans and air filters entirely. The cabinet is completely sealed, transferring internal heat to a closed-loop liquid-to-water heat exchanger using the plant's process water.
- IP65/IP66 enclosure prevents conductive iron dust ingress
- Reliable operation in ambient temperatures exceeding 55°C
- Eliminates filter cleaning cycles, saving hundreds of maintenance hours
Tailored Emission Abatement Configurator
Different processes in a steel plant present distinct flue gas challenges. Select your process area below to see how ModuPower adjusts to optimize capture efficiency.
Abundant abrasive iron ore and coke dust requiring high-capacity electrical charging.
Gas cleaning for recovery. Focus on wet precipitators and hazardous gas environments.
Sticky organic tar particles and chemical vapors requiring highly responsive voltage control.

Designed to operate continuously on unstable power grids and under high thermal stress in heavy industries.
Electrical and Operational Comparison
Data compiled from industrial field installations comparing old 50Hz single-phase transformer-rectifier (T/R) sets with SEID ModuPower® SMPS upgrades.
| Operational Feature | SEID ModuPower® | Traditional T/R Set | Key Impact |
|---|---|---|---|
| Enclosure Protection | IP65 (Liquid Cooled) | IP54 (Air Cooled) | Zero dust ingress, no filters |
| Operating Location | Remote (up to 100m) | Directly on ESP Roof | Safer, cooler maintenance |
| Voltage Waveform | Pure DC / Pulsed High Freq | 50 Hz Ripple DC | 30% higher dust collection |
| Power Factor (Grid) | > 0.95 (Active Correction) | 0.60 - 0.70 | Lower kVA load, no penalties |
