3PH TR units

Transformer Rectifier units are available in single-phase and three-phase versions. Essentially, the two systems differ in the performance of the electrostatic precipitator in terms of dust separation.

We have the capability to customize the TR unit to meet  the project-specific requirement of input voltage ranges (180V to 690V) and input frequencies (50Hz, 60Hz, …). Similarly, we offer a very wide voltage range on the output side viz. from 30 kVp to 200 kVp and output current ranging from 50 mA to 4000 mA.

If customer demands any different input and output values these can also be met using tailor-made TR sets.

Furthermore, we can adapt the main dimensions to meet any project-specific installation requirement of the electrostatic precipitator.
