Natural air circulation means that there is no fan installed in the inner chamber, thanks to which the air circulates the chamber by gravity (natural). Such a solution makes this type of dryer perfectly suitable for curing bulk substances, because they are not blown by the fan. An additional advantage of dryers with natural circulation is the quiet operation of the device. Drying ovens can be equipped with many options and additional accessories (additionally paid) apart from standard equipment.
