Brand: Munters

Model: MEN-CDCS-A1808

Type: Owner's manual

Munters MEN-CDCS-A1808 is an electronically controlled dehumidifier designed to accurately control and maintain the humidity within a space. It utilizes a microprocessor-based system to monitor and adjust the relative humidity (RH), dew point (Dp °C), or absolute humidity (X gr/kg) levels. The fan modes of the dehumidifier can be adjusted to either continuous (Fan ON), intermittent (Fan INT), or on-demand (Fan DEM), depending on the requirements of the application.
