Standard EN 12697/3
For the fully automatic recovery of bitumen after extraction.
The bitumen solvent mixture will be transferred from the Asphalt Analysator Pure basic module to the evaporation unit ROTA with evaporation flask.
The module consist of the fully automatic evaporation unit with glass set with a linear lifting drive, two heating baths for different temperatures and membrane vacuum pump in a stabile module frame.
The recovered solvent of the low temperature distillation is transferred to the solvent tank, the solvent of the high temperature distillation is transferred to the solvent waste receiver.
For the operation, it is required to provide 30L bin for solvent waste and 30l Safe-Tainer with fresh solvent.
The module ROTA can be operated only with Asphalt Analysator PURE Basic module.
The graphical user interface enable an easy operation of all evaporation procedures, especiallyfor all temperature settings of the heating bath, vacuum control and setting, horizontal and vertical drive and evaporation time.
Heating oil must be ordered separately.
