With their maximum working temperature of up to 300 °C and forced air circulation, the ovens achieve a very good temperature uniformity. They can be used for various applications such as e.g. drying, sterilizing or warm storing. Short delivery times from stock are ensured for standard models. 

  • Tmax 300 °C
  • Working temperature range: + 20 °C above room temperature up to 300 °C
  • Ovens TR 60 - TR 420 designed as tabletop models
  • Ovens TR 450 - TR 1050 designed as floor standing models
  • Horizontal forced air circulation results in temperature uniformity according to DIN 17052-1 better than +/− 5 °C in the empty work space (with closed exhaust air flap)
  • Stainless steel furnace housing, material no. 1.4016 (DIN)
  • Stainless steel chamber, alloy 304 (AISI)/(DIN material no. 1.4301), rust-resistant and easy to clean
  • Charging in multiple layers possible using removeable grids (number of removeable grids included, see table to the right)
  • Large, wide-opening swing door, hinged on the right with quick release for models TR 60 - TR 240 and TR 450
  • Double swing door with quick release for models TR 420, TR 800 and TR 1050
  • Ovens TR 800 and TR 1050 equipped with transport castors
  • Infinitely adjustable exhaust at the rear wall with operation from the front
  • PID microprocessor control with self-diagnosis system
  • 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 R8
  • Solid state relays provide for lownoise operation
  • 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 documentation 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

Additional Equipment

  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the oven and load
  • Fan speed of the air circulation fan can be reduced infinitely
  • Window for charge observing
  • Further removeable grids with rails
  • Side inlet
  • Electrical rotary device with Tmax 200 °C (associated sample holder will be individually adapted to the charge)
  • Exhaust air duct DN 80
  • Transport castors for models TR 240 - TR 450
  • Upgrading available to meet the quality requirements of AMS2750H or FDA
  • Process control and documentation via VCD software package for monitoring, documentation and control
  • Fresh-air filter to reduce dust inside the furnace
  • Process control and documentation via VCD software package for monitoring, documentation and control
