Mould Sweat Dehumidifier with Microprocessor Board is designed to remove the moisture sweat from condensing on the mould surface. The Mould Sweat Dehumidifier uses honeycomb rotor to carry out dehumidifying action, which generates a dry airflow with dew point ranging from 0 Degree C to 10 Degree C. The Mould Sweat Dehumidifier is fitted with microprocessor board to indicate machine running status and to diagnose malfunctions. Mould Sweat Dehumidifier with Microprocessor Board is facilitated with motor overload and phase reverse alarm functions.
