Defrosting
Defrost initiation
•
On demand defrost.
Defrosting interval
•
The on demand defrost system is constantly monitoring the temperatures for the evaporator in
order to prevent that the evaporator will block up with ice.
If a blocking up of the evaporator is registered by the system, a demand defrost will be initiated.
•
The minimum time between defrost is always 4 hours, but it is adjusted to the actual set point.
Defrosting method: Hot gas, combined with electrical heaters.
