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. 

  • Tmax 260 °C
  • Electrically heated (via a heating register with integrated chrome steel heating elements)
  • Temperature uniformity up to +/− 3 °C according to DIN 17052-1 (for design without track cutouts) 
  • High-quality mineral wool insulation provides for outer temperatures of < 25 °C above room temperature
  • Incl. floor insulation
  • 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
  • Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
  • Defined application within the constraints of the operating instructions
  • Controller with touch operation B500 (5 programs with 4 segments each)
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Freeware NTEdit for convenient program input via ExcelTM for WindowsTM on the PC
  • Freeware NTGraph for evaluation and documention of firings using ExcelTM for WindowsTM on the PC
  • MyNabertherm App for online monitoring of the firing on mobile devices for free download

 

Additional equipment

  • Direct or indirect gas-fired 
  • 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 motor-driven 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
  • Design for clean room heat treatment processes
  • Rotating systems e. g. for tempering processes
  • All KTR-models are also available with Tmax 300 °C
  • Process control and documentation via VCD software package for monitoring, documentation and control

Accessories

  • Adjustable plate shutters to adapt the air guide to the charge and improve temperature uniformity
  • Guide-in tracks and shelves
  • Shelves with 2/3 extraction with evenly distributed load on the whole shelve surface
  • Platform cart in combination with drive-in tracks
  • Charging cart with rack system in combination with drive-in tracks
  • Sealing shoes for ovens with drive-in tracks to improve temperature uniformity in the work space
