Heating cabinets are ideal for processes in the low temperature range up to max. 150 °C, such as for drying, preheating molds and tools or tempering and curing plastics. They have a compact design and are especially suitable for large charges. They are heated with a separate heating unit that is generally located behind the heating cabinet.
 

  • Tmax 150 °C
  • Separate, electric heating unit, consisting of heater register, air circulation system, fresh air inlet and exhaust air outlet
  • Powerful, turbulent air flow inside the oven
  • Atmosphere exchange via open fresh air inlet and exhaust air outlet
  • Temperature uniformity according to DIN 17052-1 up to +/− 6 °C
  • Wall structure with 50 mm insulation for a surface temperature Tamb.+ 25 °C, slightly higher near the door. The oven thus complies with ISO 13732-1.
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
  • 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.
  • Floor-level charging without floor insulation
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the heating cabinet and load
  • Interior with galvanized steel plate
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Controller B400 (5 programs with 4 segments each)

Process Control and Documentation

As one of the world's largest furnace manufacturers, Nabertherm has many years of experience in the design and manufacture of standardized and customer-specific control systems. All controls are characterized by a very high level of operating convenience and even the basic version has extensive basic functions. Depending on the requirements, the functions can be expanded and adapted to your needs. Professional software solutions for single or multiple furnace management as well as process and batch documentation based on our Nabertherm controllers complete the range. 

Also for compliance with industry-specific standards that define process control and documentation, such as for example, the AMS2750F for aviation, the CQI-9 in the automotive industry or the FDA in the pharmaceutical industry we offer standardized solutions.

Additional equipment

  • Steel plate to protect the base against mechanical damage 
  • Floor insulation, also with drive-in tracks or frame
  • Charging trolleys in different designs to allow for charge assembly outside the heating cabinet
  • Window in the oven door and interior lighting
  • Thermocouple inlets in various sizes
  • Cooling system with fan
  • Process control and documentation via VCD software package for monitoring, documentation and control
