What is a desiccant dehumidifier?

A desiccant dehumidifier is a type of dehumidifier that removes moisture from the air by using an adsorbing material like silica gel instead of a condensation type compressor dehumidifier. A desiccant dehumidifier is also known as adsorption dehumidifier for using an adsorbing silica gel rotor.

The sizing of the desiccant dehumidifier requires precise calculation based on the room size, existing temperature, existing humidity, target temperature, infiltration, insulation level, no. of door opening and target humidity. These calculations can be complex and error in calculation can lead to not reaching the desired target humidity levels.Therefore, we recommend that you consult our engineers by calling or sending us a Whatsapp message to +971547714946. You can also send an email to sales@dehumidifiershop.ae. We do not charge for consultation, it's completely FREE.

A desiccant dehumidifier is a specialized machine designed for low temperatures below +15°C to -30°C. Also, it is capable of reducing humidity below 40% RH unlike traditional condensation type compressor(refrigerant) dehumidifiers. So if your requirements are any of the above, you should buy a desiccant dehumidifier.

NO, they do not need to be emptied. They exhaust the moisture out during the rotor regeneration process through a regeneration outlet.

What are the disadvantages of a desiccant dehumidifier?

There are only two disadvantages to a desiccant dehumidifier - one is the silica rotor life which is typically between 7 to 10 years and second is the heat load in the dry air which can be

There is no better or worse between compressor or desiccant dehumidifier as they were designed for two different purposes. A compressor dehumidifier also known as condensation dehumidifier was designed for working in temperatures of +15°C to +40°C and to achieve humidity of 40% RH and above. This made it more suitable for HVAC applications for commercial and residential use cases.A desiccant dehumidifier on the other hand was designed to perform below +15°C till -30°C and achieve low humidity below 40%RH. That made them suitable for cold rooms and processing facilities or in a nutshell industrial use cases.

YES, they do give off heat as they have a powerful heater inside to make the air hot for regenerating the silica rotor. So the dry air that comes out of the rotor is also hotter than what it took for drying, sometimes as much as +12°C higher.

YES, a desiccant dehumidifier is the best choice for a cold room. You can contact us also for sizing calculations, we do not charge for helping customers to select the best dehumidifier for their needs.
