6.7
(F.) MEDIUM MOISTURE - HIGH TEMPERATURE (MORE THAN 65ºC)
If the temperature is higher than 65ºC there is usually a problem with air supply to the compost
material. If the temperatures are higher than 65ºC there can be a smell of ammonia.
6.7.1
BLOCKAGE IN VENTILATION SYSTEM – SMELL OF AMMONIA
The first symptom of a blockage in the ventilation system is very high temperatures.
Check that the airflow is functioning properly, outlet cover/bag is in position and that the
fan is working.
Make sure fan is functioning properly.
Remove and clean the ventilation filter and check the
airflow.
Make sure that the outlet cover / bag is tight on the outlet.
Check that the airflow is functioning
well through the biofilter (if installed).
Note! Without the fan functioning
properly and ventilation being kept clean
the biological process will not work!
Clean ventilation regularly!
6.7.2
MATERIAL IS NOT AERATED ENOUGH – SMELL OF AMMONIA
If there is no blockage in the ventilation system change the parameters so that the compost
material is aerated more.
Lower wait time.
Increase number of rotations.
Increase fan speed.
Emtpy the biofilter using the ball valve when
necessary!
