Heating cabinets are ideal for processes in the low temperature range up to max. 150 °C, such as for drying, preheating molds and tools or tempering and curing plastics. They have a compact design and are especially suitable for large charges. They are heated with a separate heating unit that is generally located behind the heating cabinet.

• 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 without 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). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• 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 oven and load
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Controller B500 (5 programs with 4 segments each)

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 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
• Safety technology according to EN 1539 (models KTR .. LS) for charges containing solvents 
• 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 or Nabertherm Control Center (NCC) 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
