Um die Wärmeverluste weiter zu verringern, wird der obere Teil des Plattenstapels seitlich von einem Heizring (HR) mit drei getrennt regelbaren Heizkreisen umgeben, was ebenfalls im Druckbehälter untergebracht werden muss.
To further reduce the heat losses, the upper part of the disk volume is laterally surrounded by a heating ring (HR) with three separately controllable heating circuits, what also has to be installed in the pressure tank.
To reduce the heat loss continues, the upper part of the plate stack side by a heating ring (HR) with three separately controllable heating circuits is surrounded, what must also be accommodated in the pressure vessel.
in order to reduce the heat loss, the upper part of the plattenstapels laterally of a heizring (hr) with three separate adjustable heizkreisen surrounded, which also needs to be placed in pressure vessels.
