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.
