The power.
Behind the precipitator.
Everything on this page exists for one purpose: to put more useful corona power into an electrostatic precipitator, so the stack runs cleaner without rebuilding the plant.
Vedika. HFPS.
The flagship upgrade: IGBT switching in place of 50 Hz thyristor energisation, for 30 to 50% lower emission with no mechanical change to the precipitator.
Vedika 2.0, above 20 kHz
Fifth generation constant-high-frequency electrostatic power source. Near-zero ripple, 10 to 20% higher field kV, 20 to 30% more corona power, spark quench in 20 microseconds.
Precicon.
ESP power controllers.
Third generation microcontroller-based control that manages the transformer-rectifier and the precipitator itself: rapping, opacity and spark management in one unit.
Precicon R
Thyristor-based ESP power controller with a long field-proven record across cement, power, steel and paper plants.
Precicon R3
Next-generation thyristor controller: faster spark response, richer diagnostics, direct integration with ESP management software.
Precicon S, IGBT module
Advanced IGBT-based power controller for installations moving to switch-mode energisation.
Ador Corona.
Transformer-rectifier sets.
More than 25,000 high-voltage TR sets supplied into ESP systems running in 109 countries.
1-phase solutions
Introduced in the 1970s and field-proven ever since. The default energisation for most conventional precipitators.
3-phase solutions
Thyristor controlled power circuit with firing control that raises average kV and stabilises collection under difficult, high-resistivity dust.
400 Hz configurations
Higher-frequency TR configurations for plants that need more corona power inside the same casing.
Rating envelope
Input 380 to 690 V, 50 or 60 Hz. Output 30 kV(P) to 200 kV(P) at no load, 50 mA to 4000 mA mean DC, design form factor up to 1.4.
Built for the stack yard
Hermetically sealed to IP-65 per IEC 947-1, lid-mounted transformer, rectifier, AC reactor and choke assembly, glass-sealed passivated avalanche diodes, and design ambient from minus 30 to plus 55 degrees C.
EPMS.
ESP management system.
One screen for the whole precipitator. EPMS runs on a standard Windows PC and uses familiar Windows controls, so plant operators pick it up quickly.
Monitoring and trending
Every field, every reading, logged and trended so performance drift is visible before it shows at the stack.
Reporting
Emission and energisation reports for internal review and for pollution control board submissions.
OEM compatible
Controls integrate with any ESP OEM's management software, with in-house software available where none exists.
Retrofits, R&M.
Nischint Care.
Most of the installed base was not built yesterday. We modernise what is already there.
Controller retrofits
Nearly 1,500 installations retrofitted with modern controllers, usually without a long plant stoppage.
ESP R&M
Electromechanical solutions for mid-life upgrade of the precipitator, including performance studies before any spend is committed.
Nischint Care
Service and spares direct from the people who built the power system: AMC programmes, emergency response and genuine spares.
