Controlled Atmosphere Top Hat Furnace 1700°C (OD12″ 21L)
Controlled Atmosphere Top Hat Furnace 1700°C (OD12″ 21L)
Overview
Top hat furnace also called elevator furnace or bell type furnace. Features stable electrically driven bottom loading system, easy for sample loading and unloading, all sides heating achieves an outstanding temperature uniformity, controlled atmosphere. Constructed dual steel housing, stability and low temperature leakage, round vertical chamber lined with 1850# high alumina ceramic fiber. Our laboratory standard top hat furnace covers Tmax 1750 degrees Celsius with capacities up to 96 liters, which is suitable for multiple heat treatments such as calcination, sintering and other processes on new materials, ceramics in labs and industrial. Programtherm supplies a variety of top hat furnaces, and programtherm top hat furnace makes your heat treatment more successful.essful.
