With decades of experience and expertise in G5 HFPS of ESP (5th generation high frequency power source of electrostatic precipitator), Chindow’s design team makes greatest effort to achieve the ease of SKD (semi-know-down) assembly process so that Chindow’s foreign partners can assemble G5 HFPS of ESP easily in their own workshop with key parts and detailed training to be supplied by Chindow and with the enclosure (cabinet) & other accessory components to be made or sourced locally by the partners.
G4 HFPS of ESP
60~120kV 200~2600mA
Chindow is the only one company in the world that manufactures both G5 HFPS and G4 HFPS of ESP
G5 HFPS of ESP
60~120kV 400~3000mA
Chindow G5 HFPS of ESP
boasts its DSP-controlled IGBT bridge working as rectifier for DC link capacitor, which contributes to all the advantages of G5 HFPS of ESP like ideal HV out waveform and consequent outstanding dust collecting performance, higher power factor, higher efficiency and lower THD (total harmonic distortion)
Chindow G4 HFPS of ESP is of the same topology and performance as the HFPS designed by major global players characterized by its diode as rectifier bridge for DC link capacitors
