[ Chamber Furnace with Atmosphere Circulation VKNC ]
VKNC Volume: from 1000 - 30000L
Max. temp. 650°C / 850°C
 
The VKNC is a bogie-hearth chamber furnace with forced vertical air circulation. This line is suitable for a wide range of heat treatment applications including tempering, artificial ageing, preheating, hot connecting, batch testing and drying. The VKNC line is designed for use under normal atmosphere where forced air circulation and dynamic progress of the temperature curve are required. The VKNC's metal interior muffle ensures an absolutely dust-free process and very precise temperature distribution according to DIN 17052-1, and its state-of the-art insulating materials give the user top energy efficiency. The VKNC comes in 650? and 850? versions.
 
Application
The VKNC bogie-hearth chamber furnace with forced circulation of the internal atmosphere is used for various types of heat treatment of large batches at temperatures up to 850 °C  where very accurate temperature distribution in the furnace is required. This furnace is especially suitable for technologies such as tempering, annealing, preheating, artificial ageing, etc.  The batch is loaded onto a bogie and then driven into the furnace.
 
Benefits
  • circulation of the internal atmosphere of the furnace provides for even temperature distribution in the inner furnace chamber;
  • door closing mechanism designed to ensure proper door sealing;
  • premium insulation materials result in low furnace operating costs.
 
Standard equipment of the furnace includes:
  • INDUSTRY controller
  • limit unit
  • door on C-hinges, opening manually to the side
  • manually-operated ventilation flap
  • manually-powered bogie
  • rails with length equal to 2.5 times the furnace length
 
Optional accessories for extra charge:
  • graphic temperature recorder
  • additional manual or electrically-driven bogie
  • hydraulic door opening (upwards)
  • ammeters for checking the status heating elements
  • pressurized cooling system
  • automatically controlled ventilation flap
  • set HT Monit (includes interface and software)
  • RS 232 or RS 485 interface
  • calibration of the measuring system
  • equipment installation
  • optimization of the temperature field to meet DIN 17052-1 ΔT10°C in the inner space of the furnace (in empty furnace at Tmax)
 
Atypical accessories:
  • second door
  • reduction or increase in the furnace power input
  • rails installed in the floor
  • second bogie - manually or electrically powered
 
Warranty: 24 months
