LVT 9/11

Ashing Furnaces with Flap Door or Lift Door

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
• Good temperature uniformity due to preheating of incoming air, temperature uniformity according to DIN 17052-1 to +/− 10 °C in the defined empty work area (from 550 °C)
• 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)
• 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 B510 (5 programs with each 4 segments)
• Solid state relays provide for lownoise operation
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
