Electrostatic Precipitator (EP) is a dust control device that collects more than 99% of particulate matter at large coal fired power plants and cement plants resulting to a hardly visible smoke emission.  EP should periodically be audited for its performance by determining the dust concentration, flowrate and other operating parameters at the inlet and outlet ducts, to keep it operating at highest efficiency and with balanced flow distribution on each duct.  Imach has been conducting electrostatic performance testing on annual basis on a number of major coal fired power plants using an established USEPA and ASTM Procedures.

Imach also conducts testing on duct network to be used as design basis in the installation or improvement of dust control systems.
