Hochtemperatur Muffelöfen

High Temperature Furnace 1100 / 1300

High-precision laboratory electric furnaces with fibre-insulated chambers made of high-quality materials. A selection of precise digital controllers and certified heating elements ensures excellent temperature stability.

The furnaces have ceramic heating plates.
To eliminate the gases or smoke released during thermal processing, an additional vent and exhaust system can be installed in the products.

	1100°C - 1300°C

Add to watch list

Muffle furnaces up to 1300 °C

Applications

Scientific laboratories
Educational institutions
Medicine
Industrial use for hardening, dissolving, normalising
Thermal treatments at temperatures of 1100 °C or 1300 °C

Equipment Basic Models

Ceramic bottom plate
Control panel on the base of the oven
Door opens upwards
Door safety switch
Equipped with the Omron E5CC non-programmable PID controller
Fast heating time due to low thermal mass build-up
Good stability and uniformity
The heating elements embedded in a vacuum-formed fibre are located in all four walls of the chamber in models with a temperature of up to 1100°C.
In models with a temperature of up to 1300°C, the heating elements are on ceramic tubes on two sides of the chamber.
Low energy consumption
One-piece chamber made of vacuum-formed ceramic fibres with high thermal efficiency
Outer casing - sheet metal, grey powder-coated
