Why Traditional ESPs Struggle

Electrostatic precipitators rely on stable, high-voltage corona fields to charge and collect dust. Traditional line-frequency T/R sets limit performance and waste power.

1. High Voltage Ripple

Standard T/R sets operate at 50/60 Hz, creating large voltage ripples. The peak voltage is limited by spark-overs, forcing the average operating voltage to remain low, which drastically reduces particle charging.

2. Slow Spark Recovery

When a spark occurs, standard T/R sets take 100ms or more to recover, during which the electric field collapse lets untreated smoke plumes escape through the exhaust stack.

3. Low Grid Power Factor

Old SCR-controlled systems draw massive reactive power with low power factors (typically 0.5 - 0.6), inflating industrial energy bills and placing heavy strain on the electrical infrastructure.

Next-Generation SMPS Technology

ModuPower® replaces slow line-frequency transformers with advanced high-frequency switch-mode power, stabilizing the corona field and maximizing energy delivery.

Switch-Mode Technology

High-Frequency Voltage Stability

Operating at 25-50 kHz, ModuPower® generates a near-flat DC voltage. This allows the system to operate much closer to the spark-over threshold, maximizing corona power and capturing sub-micron particulates with up to 30% higher efficiency.

  • Near-zero voltage ripple for stable, high-voltage fields
  • Dramatic efficiency gains in collecting fine PM2.5 and PM10 dust
  • Significantly smaller active footprint than old T/R systems

Modular Fault Tolerance & Speed

By using multiple parallel IGBT power modules, ModuPower® provides inherent redundancy. If a module fails, the remaining units continue running, keeping the ESP online. Microsecond-speed spark detection senses spark-overs and recovers power in less than 1ms, eliminating visible smoke stack releases.

  • Microsecond spark quenching and sub-millisecond recovery
  • Parallel module structure allows hot-swappable maintenance
  • Smart voltage controllers optimize power levels automatically

Cement Dust Capture

Stable Corona in High-Dust Kilns

Cement kiln gases contain high concentration of resistive dust, causing back-corona in traditional systems. ModuPower®'s pulsed charging mode controls the electrical field dynamically, preventing back-corona, maintaining stable operations, and keeping emissions below 5 mg/m³.
