DESICCANT WHEELSAdvanced rotor technologyfrom the market leader within desiccant dehumidification

Munters energy efficient technique - your guaranteeCarl Munters designed a rotor for the futureSince the world famous Swedish scientist Carl Munters invented and patentedthe first desiccant wheel (rotor) dehumidifier over 60 years ago, it hasbeen generally accepted that all high performance industrial dehumidifiersemploy desiccant wheel technology. Munters is the only supplier holdingknow-how, R&D and production in house from the very first rotor fibre to thecompleted air treatment system.This simple and extraordinary effective technology has since been advancedgreatly thanks to decades of Munters research and development grantingour customers optimized drying performance whilst operating expenses arebeing minimized.The Munters desiccant wheel stands out as the most energy efficienttechnique for creating humidity controlled environments.Our purge technology reduces regeneration energy by up to 30% and bymeans of cooler supply air the need of post cooling can be reduced by upto 70%.The rotating heart of Munters dehumidifiersHow the desiccant wheel worksThe Munters desiccant wheel works on the principle of sorption, whichis the adsorption or the absorption process by which a desiccantremoves water vapor directly from the air.Dry airProcess airThe air to be dried passes through the desiccant wheel and thedesiccant removes the water vapor directly from the air and holds itwhile rotating.As the moisture-laden desiccant passes through the regeneration sector,the water vapor is transferred to a heated airstream, which is exhaustedto the outside.This process is continuous, allowing for highly effective and uninterrupteddehumidification.Wet airRegeneration airDrive motorEnergy recovery sectorsfor enhanced performance available- saving up to 30% energy

Proven technique - outstanding qualityMore than 300,000 rotors producedMunters are a global leader in energy efficient air treatment solutionsand have experience of over 300,000 installations worldwide andcontinues to set the world’s standard for desiccant wheel production.With our own multiple desiccant wheel production facilities worldwide,Munters provide a wide range of desiccant options and has obtainedmore than 250 patents in desiccant technology.Certified bactericidal rotors for your safetyCustomer health and safety is essential to Munters which is clearlyreflected in the design of the rotors.Our rotors are continuously being tested independently and havemost recently been proven by The Swedish Institute for Food andBiotechnology to have both bactericidal and fungicidal properties. Notonly the rotor surface but also air streams were tested. Furthermore therotors are proven not to emit particles to the processed air and the rotorfibres used have a size not respirable and preclude associated healthhazards.Munters rotors and the hygienic design of our air handling systems formthe optimal solution in situations where hygiene cannot be compromizedeg. in baby milk powder production.Proven outstanding qualityMade of a non-metallic, ceramic composite, Munters highly hygroscopicrotors are engineered to provide superior strength and durability. Theunique and thorough manufacturing processes assure that the desiccantmedia and the casing is integrated perfectly.Our quality control tolerates no imperfections that can inhibitthe performance of the dehumidifier, and the desiccant wheel ischaracterized by a smooth and regular surface - designed to last.Most Munters rotor factories are complying with the highenvironmentally management standards of ISO14001.

The perfect desiccantwheel choice for 90% of all drying applications.Some production processes require a controlled climate witha relative humidity as low as down to 0.5 % RH. Our lowdewpoint rotors will work effectively down to dew pointsat -65 C solving the delicate problem at the world’s mostdemanding manufacturers.

Worldwide references confirm the hygienic advantages, reliability and energy efficiencyof Munters QuantumTM rotors for demanding processes like dairy and baby milk powder production.

Purge sectors - save up to 30% energyPurge sector optionsFor an even higher energy efficiency our rotors can be provided with an energy recovering purge sector that comes both as apre-installed feature or as a retrofit.Recovering heat from the regeneration process through multiple methods the energy needed for regeneration is reduced by upto 30%.A special green power purge sector is available for systems supplying air for extremely low dewpoint applicationslike lithium battery production.Energy efficiency purgePower PurgeTMBy adding an extra sector on the process inlet and outletside, an external duct is used to recirculate air into theregeneration cycle after the heater.(A partial air stream is led to the regeneration air streamafter the heater).By adding two sectors on each side of the rotor, positionedboth before and after the regeneration sector, the energyneeded for regeneration is reduced just like an eventual needof cooling of the dry air is decreased.Depending on air flows, unit type, application etc., thesavings on energy needed for regeneration reaches up to25 % A separate air stream recirculates and cools the rotormaterial on the process air inlet side and pre warms therotor before it enters the regeneration sector.
