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.
