Desiccant Dehumidifier is Best for Large Buildings

Both the desiccant and the refrigerant dehumidifier function well to remove moisture from their surrounding environment. However, if you have a very large area to dry down, such as a warehouse or ice-skating arena, then the desiccant dehumidifier will be more efficient for the job.

The way these units operate is very different than a refrigerant system. It draws air into itself and passes it over a desiccant material, such as silica gel, which will absorb the moisture. Moisture is then expelled by a heater of some sort and then the wet air would be vented to the outdoors. Refrigerant systems however use cooling coils and water is dispelled into a collection pan or pumped down a drain. The main benefit of a desiccant dehumidifier is its ability to dry even in colder conditions where refrigerant style units tend to freeze up.

These systems are available in large scales to suit the largest areas for dehumidification, making it suitable for large buildings. Refrigerants are more portable making them more suitable for areas with less cubic feet of air to be dried. These would be areas like homes or small offices.  Since there is no actual water produced by a desiccant dehumidifier, it makes it a rather convenient choice for large buildings where finding a drain close by may not always be possible.  Since these systems use heat to remove the moisture, the return air is not only dry but also warm.  Since these units are used to extract moisture out of the air, most will auto detect when the humidity level is dry enough and stop operating til the humidity level rises.  This will prevent over drying of sensitive materials.

The most common and best applications of desiccant dehumidifiers are seen in supermarkets, ice rinks, restaurants, hotels and motels, refineries, and many other large industrial and commercial buildings.  These would be areas prone to spikes in humidity from time to time that the HVAC unit can not adequately control.

This is an established technology that has been used successfully for many years in commercial and industrial applications. Its efficiency in dehumidification in large facilities where humidity control is required makes it a top choice for commercial establishments.  As with other dehumidifiers, it also serves to reduce mold and mildew problems and can provide more purified air depending on the types of air filters that are used in the unit. The difference with these units compared to refrigerants is that it does its job with minimal noise and continues to work in conditions below 70 degrees.

Along with the many advantages a desiccant dehumidifier has over a refrigerant unit, it is also more energy efficient, making it a cost-efficient choice in drying large areas. There’s no doubt that for large spaces and large buildings, these systems will deliver results in less time, use less energy and operate at a reduced cost.
