HL 109 Safety Devices Training Panel Show data sheet (pdf file) Print page
Technical Description

An electrically heated pressure vessel is mounted on the panel of the trainer. The vessel can be filled via different pipe sections. One pipe section is equipped with a system of safety devices for protecting a sealed water heater. The pressure vessel is also equipped with a thermal discharge safety device that discharges to a blow-off pipe.

  When the pressure or temperature level set is exceeded, the safety devices are tripped. Pressure and temperature in the system are displayed.
