The chamber ovens of the KTR range can be used for complex drying processes and heat treatment of charges to an application temperature of 260 °C. The high-performance air circulation enables optimum temperature uniformity throughout the work space. A wide range of accessories allow the chamber ovens to be modified to meet specific process requirements.

Standard Equipment

  • Tmax 260  °C
  • Electrically heated (via a heating register with integrated chrome steel heating elements) or gas-fired (direct or indirect gas-fired including injection of the hot air into the intake duct)
  • Temperature uniformity up to +/− 3  °C according to DIN 17052-1 (for design wihout track cutouts)
  • High-quality mineral wool insulation provides for outer temperatures of < 25  °C above room temperature
  • Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
  • High air exchange for fast drying processes
  • Double-wing door for furnaces KTR 2300 and larger
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Controller B500 (5 prgrams with each 4 segments)
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

 

Additional equipment

Additional Equipment

  • Base frame to charge the oven via a charging forklift
  • Additional Door in the back for charging from both sides or to use the oven as lock between two rooms
  • Fan system for faster cooling with manual or motorized control of the exhaust flaps
  • Programmed opening and closing of exhaust air flaps
  • Air circulation with speed control, recommendable for processes with light or sensitive charge
  • Observation window and furnace chamber lighting
  • All KTR-models are also available with Tmax 300 °C
  • Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
