January 16, 2019 admin 0 Comments

Product Specification Chamber oven KTR 22500/S with chamber lightning and drive-in tracks with insulated plugs which provide for an optimal temperature uniformity

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. The design for the heat treatment of flammable materials in conformance with EN 1539 is available for all sizes.

  • Tmax 260  °C
  • Volume: 1000L-22500L
  • 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
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • High air exchange for fast drying processes
  • Double-wing door for furnaces KTR 3100 and larger
  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load
  • Incl. floor insulation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

  • Track cutouts for level drive-in of charging cart
  • 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 (NFPA 86) for charges containing solvents
  • Charging cart with or without rack system
  • Design for clean room heat treatment processes
  • Rotating systems for tempering processes
  • 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
  • All KTR-models are also available with Tmax 300 °C.
