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 30 - 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 30 - 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 R7
• 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 Excel^TM for Windows^TM on the PC
• Freeware NTGraph for evaluation and documention of firings using Excel^TM for Windows^TM 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
