RD 30/200/11 - RD 30/200/13

The RD product line furnaces convince with their unbeatable price-performance ratio, very compact outer dimensions and their low weight. These all-rounders are equipped with a working tube which also serves as support for the heating wires. Thus, the working tube is part of the furnace heating which has the advantage that the furnaces achieve very high heat-up rates. The furnaces can be supplied for 1100 °C or 1300 °C.

All models are designed for horizontal application. If the customer requires protective gas atmosphere, a separate working tube, e.g. made of quartz glass, must be inserted in the working tube.

• Tmax 1100 °C or 1300 °C
• Dual shell housing made of sheets of textured stainless steel
• Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
• Inner diameter of the tube: 30 mm, heated length: 200 mm
• Working tube made of C 530 material including two fiber plugs as standard
• Thermocouple type K (1100 °C) or type S (1300 °C)
• Solid state relays provide for low-noise operation of the heating
• Heating wires wound directly around the working tube resulting in very fast heat-up rates
• Defined application within the constraints of the operating instructions

• Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
• Gas supply system for non-flammable protective or reactive gas

R 50/250/12 - R 170/1000/13
