The range of AAF ashing furnaces is designed specifically to provide optimum ashing conditions to ensure complete combustion of the sample


The AAF 11/3 & AAF 11/7 ashing furnaces provide a continuous flow of preheated air through the chamber, and are designed to comply with ISO 1171:2010, ASTM D3174-04: 2010 and ASTM D4422. 

 

Features:

  • 1100°C maximum operating temperature
  • Carbolite Gero 301 single ramp to setpoint & process timer
  • Large floor area allows for large number of samples
  • Ideal for ashing foods, plastics, coal & other hydrocarbon materials
  • Designed to comply with ISO 1171:2010, ASTM D3174-04: 2010 and ASTM D4422
  • Wire elements are protected from chemical & mechanical damage by a hard wearing aluminabased liner
  • 4 sided heating (2 sides, roof & hearth)
  • Air inlet & tall chimney give airflow of 4 to 5 changes per minute
  • Low chamber height holds airflow close to samples for optimum combustion
  • Powerful elements with graded winding compensate for heat loss due to high airflow
  • Preheating of air before it enters the chamber gives excellent uniformity
  • Sample tray and loading handle


Options (specify t hese at time of order) 

  • 2 phase electrical supply for AAF 11/7
  • Over-temperature protection (recommended to protect valuable contents & for unattended operation)
  • A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications

 

Airflow in AAF 11/3 and AAF 11/7
  1. A tall 50 mm diameter chimney (AAF 11/7),or 35 mm on AAF 11/3, pulls the air through the chamber
  2. Pre-heated air enters the chamber after circulating around the outside of the chamber
  3. Air inlet
