The heating surface of the heating mantle for glass flasks up to 200 liters is made of smooth glass?yarn fabric which is adapted to the shape of the flask. This heating mantle can be fixed e.g. in a supporting stand with four movable threaded bolts. Due to the heavy weight, the glass flask should be supported additionally.
Each heating zone has a NiCr-Ni (K) temperature sensor. The maximum operating temperature is 450 °C.
To allow easy maintenance and mounting, the heating mantle is equipped with a 16-pole industrial flange plug.
