Built-in safety elements and measures
The KjelMaster K-375 has monitored protective doors which prevent a distillation to start while a door is
open. A running distillation is immediately interrupted when a door is opened. The dosing of reagents is
also immediately stopped.
The sample changers K-376 / K-377 have monitored protective shields. Running a sample changer with
opened shield is impossible. For the K-377 only the shield of the tray, that is currently not in use can be
opened.
K-375:
∙ Protective door: Safety appliance to protect users from burns at the splash protector (distillation
area) which is hot during distillation.
∙ Protective door sensors: Prevents to start a distillation with the protective doors open and stops the
distillation as soon as a protective door is opened during the process.
∙ Sample tube sensor: Prevents to start a distillation without a sample tube inserted.
∙ Service door sensor/switch: Electrical power is disconnected immediately when the service door is
opened, thus preventing electrical shock during maintenance.
K-376:
∙ Protective shield with sensor/switch: As soon as the shield is opened an alarm sound is triggered
and any movement of the arm is stopped.
K-377:
∙ Protective shield with sensor/switch: As soon as the shield of the tray in use is opened an alarms
sound is triggered and any movement of the arm is stopped. (The shield of the respective tray that
is not operated can still be opened without any restrictions.)
