Application information
-
compressive load on the heater: max. 50 N/cm² two-dimensional pressure
-
With container heaters with changing levels the temperature controller or temperature sensor must be attached to the upper side of the heater (= hottest position when the level drops)
-
Depending on the heater design, the minimum bending radius is 30 mm
-
Silicone heaters must not be bent
-
The heaters must not be cut or mechanically damaged
-
The heaters may only be operated with the prescribed voltage
-
Incoming goods inspections are not carried out for materials that are provided, because we assume that these parts are supplied in a perfect condition. Materials must be provided not less than three weeks before the confirmed delivery date for the heaters, so that this date can be complied with.
Maximum temperature loads
-
The maximum temperature load for silicone heaters is 240°C
-
The maximum temperature load for silicone heaters with self-adhesive foil is 150°C
To make sure that the heater element does not overheat a suitable temperature controller is suggested during the planning stage, or supplied on request. With power densities > 0.45 W/cm² we recommend additional security using a thermal cut-out.
The temperature that can be reached with a heater element depends on the following factors:
-
Ambient temperature
-
Thermal conductivity of the medium/material to be heated
-
Insulation of the heater element and the heated medium
-
Radiant emittance (heat loss through eternal influences)
-
Thermal conductivity of the heater carrier
-
Flow rate of the medium to be heated
