Can you tell us what the level of automation of your evaporator is?
The COMPLETE working cycle of an evaporator of the serial-V (vertical boiler) is controlled in FULLY AUTO-MODE by a simple and reliable PLC with relevant software. This makes it unnecessary to have the presence of an operative. It is obvious that, as with any kind of "machine" we advise to make visual inspections say every 2-3 hours. I do wish to mention, however, that even in the case of a problem there is no risk whatsoever because the safety controls with which the installation is equipped will stop the unit and activate relevant alarms calling the attention of an operative.
