  These tube furnaces can be used for horizontal (RSH) or vertical (RSV) operation. The split-type design makes it easy to change the working tube. It allows
  for a comfortable exchange of various working tubes (e.g. working tubes made of different materials).
  Using a wide range of accessories, these professional tube furnaces can be optimally tailored for your process. By adding different gas supply packages,
  you can work in a protective gas atmosphere, with gases or in a vacuum. In addition to the convenient standard controllers, modern PLC controls can also
  be used to control the process.

  Standard Equipment
  · Tmax 1100 °C or 1300 °C
  · Single-zoned design
  · RSV models with frame for vertical operation

  The high-temperature furnaces HTC 16/16 – HTC 450/16 are heated by vertically hung SiC rods, which makes them especially suitable for sintering
  processes up to a maximum operating temperature of 1550 °C. For some processes, e.g. for sintering zirconium oxide, the absence of interactivity
  between the charge and the SiC rods, these models are more suitable than the alternatives heated with molybdenum disilicide elements. The basic
  construction of these furnaces make them comparable with the already familiar models in the HT product line and they can be upgraded with the same
  additional equipment.

  Standard Equipment

  ·Tmax 1550 °C
  · Dual shell housing with fan cooling for low shell temperatures
  · Heating from both sides via vertically mounted SiC rods
  · High-quality fiber insulation backed by special insulation
  · Side insulation constructed with tongue and groove blocks provides for low heat
  loss to the outside
  · Long-life roof insulation with special suspension
  · Chain-guided parallel swivel door for defined opening and closing of the door
  without destroying the insulation
  · Two-door design (front/back) for high-temperature furnaces > HTC 276/..
  · Labyrinth sealing ensures the least possible temperature loss in the door area
  · Reinforced floor as protection for bottom insulation
  · Vapor vent in the furnace roof with motorized exhaust air flaps, controlled via the
  extra function of the controller
  · Heating elements switched via SCR‘s
  · Over-temperature limiter with adjustable cutout temperature as temperature
  limiter to protect the oven and load

  To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The chamber furnaces
  N 7/H – N 87/H are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation
  under protective gas, roller guides, or a cooling station with a quench tank. Even high-performance applications like the annealing of titanium in medical
  applications can be implemented without the use of expensive and complicated annealing systems.

  Standard Equipment
  · Tmax 1280 °C
  · Deep furnace chamber with three-sides heating: from both side walls and bottom
  · Heating elements on support tubes ensure free heat radiation and a long service
  life
  · Bottom heating protected by heat-resistant SiC plate
  · Temperature uniformity up to +/− 10 °C according to DIN 17052-1
  · Low energy consumption due to multi-layer insulation
  · Base frame included in the delivery, N 7/H – N 17/HR designed as table-top
  model
  · Parallel guided downward swinging door (user protected from heat radiation)
  · Door movement cushioned with gas dampers/struts

  Ashing furnace LV ../11 is designed especially for ashing processes to 1050 °C in the laboratory. Applications include determining loss on ignition, ashing
  food and plastics for subsequent substance analysis. A special fresh-air and exhaust air system ensures that the air is replaced 6 times per minute so that
  there is always sufficient oxygen for the ashing process. Incoming air passes the furnace heating and is pre-heated to ensure good temperature uniformity.

  Standard Equipment
  · Tmax 1100 °C
  · Heating from two sides
  · Ceramic heating plates with integral heating element which is safeguarded, and
  easy to replace
  · Air exchange of more than 6 times per minute

  uniformity according to DIN 17052-1 to +/− 10 °C in the defined empty work area
  (from 550 °C)
  · Suitable for many standardized ashing processes according to ISO, ASTM, EN,
  and DIN
  · Optional flap door (LV) which can be used as work platform or lift door (LVT) with
  hot surface facing away from the operator
  · Controller B410 (5 programs with each 4 segments), alternative controllers

   

  Additional Equipment
  · Over-temperature limiter with adjustable cutout temperature as temperature
  limiter to protect the oven and load
