Desiccant & Mechanical Dehumidification Systems

Lincoln Associates can supply and configure a wide range of dehumidifiers and dehumidification systems, with air volumes as low as 50 cfm up to and beyond 100,000 cfm. Munters manufactures and services Cargocaire desiccant dehumidifiers and dehumidification systems. Our equipment removes moisture from the air, which allows you to control humidity in your buildings and industrial processes to very low levels. In general a desiccant dehumidifier is comprised of four major components. The component that holds the desiccant of which there are several types, a fan to move the air to be dehumidified (process air) through the desiccant holder, a fan to move the low humidity air for drying the desiccant through the desiccant holder and a heater to heat the air that will be used to dry the desiccant (regeneration air).

Some desiccant dehumidifiers use a cyclical type of operation where the desiccant is packed into a container through which the air to be dehumidified is passed. When the desiccant in the container reaches a certain level of moisture content a low humidity air stream is then passed through the container until the desiccant is dry enough to be used for dehumidifying again (regenerated). When two containers are used one can be dehumidifying while the other is being regenerated and vice versa. These types of machines produce varying levels of dehumidification due to the rising moisture content of the desiccant during the dehumidifying stage.

Mechanical (refrigeration-based) dehumidification systems are more economical than desiccants at high temperatures and high moisture levels. In general, mechanical refrigeration systems are seldom used for applications below 45% RH. For example, in order to maintain an outlet condition of 40% RH it would be necessary to bring the coil temperature down to 300 F, which results in the formation of ice on the coil and a reduction in moisture removal capacity. Efforts to prevent this (defrost cycles, tandem coils, brine solutions etc.) can be very cumbersome and expensive.

Lincoln Associates can provide design and application assistance on both of these systems.
