DESCRIPTION FOR ASHING FURNACE LVT15/11/C550, TMAX.1100,
lift door, overtemperature limit controller, hole for thermocouple in rear wall
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
Additional Equipment
Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
Port for thermocouple in the rear wall or in the furnace door
Charging rack with closed or perforated trays for loading the furnace in two levels incl. holder for inserting/removing the trays up to a max. temperature of 800 °C and a max. loading weight per layer of 2 kg for the LV(T) 9/11 respectively 3 kg for the LV(T) 15/11
Process control and documentation via VCD software package for monitoring, documentation and control
