Dust Resistivity Lab
Dust resistivity has long been recognized as the primary factor in determining the performance of electrostatic precipitators (ESPs). Changes in dust resistivity from optimum values to extreme values can change the collection efficiency of ESPs dramatically. Therefore, ESP sizing and performance evaluation must always include resistivity as a primary factor.
Since resistivity is such an important factor in ESP design and performance evaluation, Nol-Tec’s Lodge Cottrell division operates our own laboratory facility to measure resistivity. This laboratory equipment and test personnel have been in service for more than 30 years. Our equipment can handle one to four dust samples simultaneously, while varying gas temperature and moisture content. This gives us the capability to process a large number of dust samples in a relatively short period of time, as opposed to laboratory equipment that might test only one sample at a time.
