AND 100 How it works The core of the Carousel Plus Dryer is the Munters unique fluted desiccant rotor which contains molecular sieve desiccant The molecular sieve has been grown into the rotor s porous fiberglass substrate preventing the possibility of desiccant break down and dusting over time The desiccant rotor revolves slowly at the rate of 12 revolu tions per hour passing through three cycles with each revolution The benefits The high airflow across the surface area of the rotor produces a resin drying low dewpoint within five minutes of start up and offers multi year media life with virtually no maintenance Return Air Filter The continuously revolving rotor provides rock steady temperature and dewpoint control The rotor technology minimizes energy consumption by reducing the structural mass less structural mass to heat means less energy wasted Which package is right for you STANDARD PACKAGES MX MY DC 1 control DC 2 control Audible and visual alarms Temperature setback Dewpoint monitor Dewpoint control Communications Self loading hopper FEATURE DESCRIPTIONS Audible and visual alarms A combination of a blinking red alarm light and a horn alert the operator to any shut down alarm Temperature setback Automatically reduces the drying temperature to a lower standby mode when the machine throughput is reduced or stopped Dewpoint monitor All
