This module includes all component parts of the rotary evaporator for monitoring and controlling the distillation process parameters. The operating panel with analogue and/or digitally display devices and buttons, positioned for the convenience of the operator, is placed in the upper housing part. The main switch is directly below the operator panel. All housings with their switch and control gear are, as with the terminal boxes, placed in the lower housing part of the rotary evaporator and easily accessible from outside by a removable cover. Explosion-protected models have compression-proof enclosed housings. In all other cases they are designed splash-proof (IP 54 type of protection). The operator panels have analogue or digital displays depending on the model (see technical data).
- The head temperature in the condenser
- The bath temperature
- The vacuum
- The speed of the rotary flask (special request)
