ML-L Series

with Air Cooled Condenser

Product Description

The ML690L desiccant dehumidifier with air cooled condenser isdesigned to efficiently dehumidify in unheated closed spaces. Thewet air from the dehumidifier is passed through the air cooledcondenser and then returned to the rotor in a closed loop circuit.The components within the closed loop are constructed of stainlesssteel and thermoset plastic. Water removed by the condenser isdrained away. The heat from the air cooled condenser is theneither used in the application or ducted away.Its rugged formed metal frame and access panels are produced fromcorrosion resistant Aluzink®. The electrical system conforms toestablished ML-L Series standards as well as to both harmonisedEuropean Standards and to CE marking 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-L Series rotor technology is an extrarotor sector which provides high capacity, while simultaneouslyrecovering heat, thereby effectively reducing the electrical powerrequirement. The reactivation air is continually re-circulated.
