Propane Filter Washing with Hot Kerosene

Temperatures required to successfully melt the wax from the filter cloth do not allow the use of liquefied propane due to the very high pressure required. 

Instead kerosene is used to wash the filters. Kero wash temperature is typically controlled. If the wash temperature is too low the wax crystals will not be melted, and if the wash temperature is too high wire migration will increase leading to reduced wire life and/or more fi equent wire retensioning.
