Defrosting
Defrosting with hot gas
As standard, the freeze-dryer is equipped with a hot-gas defrosting system.
In order to defrost the ice condenser, heated refrigerant is fed through the
heating coil. In addition, the bottom of the ice condenser chamber is heated
by way of a heating collar.
In order to avoid damage, the condensate must be drained off through the
media drain valve directly after the completion of the defrosting process.
Then, any residual water must be removed from the ice condenser
chamber by way of a cloth.
