For over 20 years, Quick-Quench Bottom Drop Furnaces have been the industry standard to solution heat-treat aluminum to specifications that call for +/ 5 F temperature control and a 5 second quench. They are also used to heat treat ferrous metal parts for those who want the convenience and space savings offered by the quench tank located under the furnace.
Bottom drop furnaces are built for heat treating material where the material is lowered very quickly from the soaking zone into a quench tank.
