Definitions

  • the control head 7 is surrounded by an induction coil 80.
  • an induction coil 80 In this way, more heat is supplied to the control head when the induction coil is excited than would be necessary to regulate the overheating ⁇ tü.
  • ⁇ tü 8 K at an evaporation pressure of approx. 3 bar to reduce the overheating to 2 K and an output of approx. 3 W is required.
