Nabertherm Forced Air Oven – up to 300 °C with Safety Technology According to EN 1539

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

Standard Equipment

• Tmax 300 °C
• Working temperature range: + 20 °C above room temperature up to 300 °C
• Ovens TR 30 – TR 420 are designed as tabletop models
• Ovens TR 450 – TR 1050 are 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 oven (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
• Exclusive use of insulation materials without categorisation according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fibre” (RCF), which is classified as possibly carcinogenic, is not used.
• Charging in multiple layers is possible using removable grids (number of removable grids included, see table)
• 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 are equipped with transport castors
• Infinitely adjustable exhaust at the rear wall with operation from the front
• PID microprocessor control with a self-diagnosis system
• Models TR .. LS: Safety technology according to EN 1539 for charges containing liquid solvents, achievable temperature uniformity +/− 8 °C according to DIN 17052-1 in the empty oven (with closed exhaust air flap)
• Controller R7 (resp. C550 for TR ..LS)
• Solid-state relays provide for low-noise operation
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional Equipment

• Over-temperature limiter with adjustable cutout temperature as a temperature limiter to protect the oven and load
• The fan speed of the air circulation fan can be reduced infinitely
• Window for charge observing
• Further removable grids with rails
• Side inlet
• Electrical rotary device (associated sample holder will be individually adapted to the charge)
• Exhaust air duct DN 80
• Transport castors for models TR 240 – TR 450
• Upgrading is available to meet the quality requirements of AMS2750F or FDA
• Process control and documentation via the VCD software package for monitoring, documentation and control
• Fresh-air filter to reduce dust inside the furnace
