The first generation of hot low pressure cleaning was the steam cleaner one to two gallons of water heated 300 500 F were discharged against dirt at 100 125 PSI the water left the nozzle the pressure drop caused the water temperature to drop to 212 and much of the water temperature dissipated into the air as water vapor Dirt and grease were melted and dripped off of the object being washed The second generation of hot cleaning now uses 600 1200 PSI high pressure at 100 200 F water temperature 1 5 to 5 0 GPM are discharged against the dirt The un vaporized hot water strikes the dirt cutting sticky and stubborn dirt with kinetic energy and thermal action Siebring Manufacturing has been in the business since 1910 Siebring was involved in the first generation of steam cleaning equipment and has continually worked in the development of and rugged hot high pressure washers In the mid sixties Siebring was again was on the ground floor with new developments incorporating new designs higher pressure pump applications and the like GENERAL APPLICATIONS Greases with heavy wax bases animal oils in animal waste and dirt and grime are targets for this equipment Engine and transmission rebuilding heavy equipment in farm construction excavation and industry are applications for easy cleaning in short periods of time Building preparation for painting special shop maintenance cleaning animal confinements meat
