Values shown are the standard manufacturing range. Final parameters are calculated from your gas volume, dust or pollutant load, temperature and the emission standard in force at your site.

Customisation options

  • Field number and collecting area matched to inlet load and target outlet value
  • Media selection by gas temperature and chemistry
  • Shared casing dimensions to fit the existing structure and duct centreline
  • Integrated control panel for rectifier, pulse cleaning and fan VFD

Export packing & delivery

  • Casing and internal division shipped in bolted modules
  • Collecting plates, electrodes and insulators packed in steel frames
  • High voltage components packed separately with test records

Drawings, assembly sequence, manual and test records are supplied with every shipment. On-site engineer dispatch can be arranged for complete system projects.
