Product description

The MX² 55 combines traditional Munters strengths like efficiency and robustness with modern state of the art technology like modulating RH control and communication.

Low energy consumption and reliability are important in todays processes. Our modern control system together with high efficient fans which, meet the EU Ecodesign directive, supported with frequency converters give you numerous options to optimise your energy consumption. The Energy Recovery Purge (ERP) or Energy Efficiency Purge (EEP) is available as a standard option in order to save energy.

The MX² 55 is equipped with a number of alarm functions to ensure total control of the dehumidification process. Frame casing and outer panels are made of corrosion resistant AluZink and coated in RAL 7035.

The MX² 55 dehumidifier covers a wide range of needs by providing a variety of standard functions. The numerous options will allow pre- and post treatment by simply adding mechanical and electrical components.

The MX² 55 can be supplied with 3 different reactivation alternatives - electrical, steam and gas. A service indicator activates when a preventative service is due, this is a standard feature. To make installation easier the process fan inlet has been designed to allow for different outlet positions.

The electrical equipment conforms to EN 60204 (IEC204). The MX² series of dehumidifiers conform to both harmonised European standards and technical specifications for CE marking.
