Desiccant drying system IDT
Desiccant-type systems work according to the absorption principle, i. e. closed-loop heating and dehumidification by a chamber containing drying agent.
Hot air system IHT
IHT series dryers make use of environmental air. Hence, the drying result depends on the environmental conditions (relative air humidity and temperature). Hot air systems are mainly used for pre-heating or drying non-hygroscopic materials.
