Technical details

Furnace housing

In order to avoid corrosion in case of, e.g. ashing, combustion, digestion or aggressive binders, the VMK-furnaces are installed in a stainless steel housing. Below the door there is a shelf made of stainless steel, which also protects the operating elements from thermal and mechanical damage. Exhaust connecting piece made of stainless steel is installed at the rear wall.

 

Fibre insulation

The furnace chamber is vacuum formed in one ceramic fiber block. That way high insulation values can be achieved which result in a considerable reduction of the wall thickness of the insulation as well as of the weight at low energy saving volume. A stable, finned ceramic plate in the furnace bottom guarantees easy charging.

 

Heating

Long-live Kanthal A1 heating elements are embedded in the fiber muffle. The heating is effected from three sides so that a uniform temperature distribution in the furnace chamber is achieved. In connection with the insulation, faster heating and cooling cycles are obtained as well as energy saving of app. 40 %.

 

Control system

The control system is installed on the bottom side of the furnace (below the deposit) and as a standard it is equipped with the following instruments:

  • Temperature controller G400
  • 2 setpoint or 3 setpoint controller with PID behaviour
  • One heating up speed freely programmable / ramp function (0,0 – 999,9 dig/min)
  • Display of actual value (desired value press button)
  • Self-optimization prevents overshooting (pre-adjustment or automatic self-optimization)
  • Separation of control level and configuration level (prevents undesired changes)
  • Alarm signal in case of thermocouple fracture
  • Timer switch on delay/switch out delay (adjustable 0,0 – 99,59 h/min)
  • Thermocouple NiCr-Ni (K) installed in furnace
