ML Series

Desiccant Dehumidifier

Product Description

The ML270 desiccant dehumidifier is designed to efficientlydehumidify in low moisture applications. It is equipped with aninternally sealed rotor unit. The rotor casing is constructed ofdurable thermoset plastic and contains isolated sections thatprovide a precise balance for dehumidification, reactivation, andheat recovery airflows. Its rugged formed metal frame and accesspanels are produced from corrosion resistant Aluzink®.The electrical control system conforms to EN 60204 (IEC204)standards. The electrical components are mounted on busbars andare constructed of halogen-free plastic. The electrical system isdesigned for up to 690V and 60º C. ML Series dehumidifiersconform to both harmonised European Standards and to CEmarking specifications.

Munters Rotor Technology

The desiccant rotor is manufactured from a corrugated compositematerial that is highly effective at attracting and holding watervapour. Every Munters dehumidifier applies a unique rotortechnology. Airflows, air conditions, rotor sections, and rotorrotation speeds are optimised for specific applications. Aninnovative control system maximises the units energy efficiency. A characteristic of the ML Series rotor technology is an extra rotorsector which provides high capacity, while simultaneouslyrecovering heat, thereby effectively reducing the electrical powerrequirement.
