In this article, I will try to explain the different types of dehumidifiers. Also, we will discuss how to buy a dehumidifier that suitable for your application. We will focus on models based on the working principle. In particular, we will study the desiccant & refrigerant dehumidifier types.
Many suppliers offer you a dehumidifier that is available with them. Besides, they offer it without knowing about your application. Always choose the unit that has a working principle suitable for use. For example, a cold room needs a desiccant type dehumidifier. Condensation based units will not withstand the coldness of the cold room.
In the same vein, for the indoor pool, you can’t afford to choose a desiccant dehumidifier. The reason behind it is that compressor dehumidifiers will be cheaper. This article will explain to you the basics of dehumidifier types.
Types of dehumidifiers based on the working principle.
There are three kinds of dehumidifiers based on the working principle. These types are condensation dehumidifier, desiccant dehumidifier, and Peltier dehumidifier. Before buying a dehumidifier, you should know which kind of unit you should pick up.
Desiccant dehumidifier type.
The desiccant types of dehumidifiers are suitable for cold spaces. Silica gel has an inborn property of absorbing moisture. Hence, it used as a dehumidifying agent. But, once moisture absorbs by the desiccant, it becomes wet. And to reuse it, we need to dry it.
The operating cost of a desiccant dehumidifier type is high. On top of it, this unit costs a high initial price. Thus, it is not wise to use such a costly system for typical use. Use it when to dehumidify the cold area.
Compressor based dehumidifier.
This type of dehumidifier also called a refrigerant dehumidifier. This kind of unit should use for dry normal temperature room. As compared to desiccant units, it has a low initial and running cost. As a result, a compressor dehumidifier always a winner.
Peltier types of dehumidifiers.
This unit work on the thermoelectric principle. When the voltage applied to two different metal, then the temperature difference created. Thus, one metal becomes hot, and the other becomes cold. Cold metal side used for condensation of humid air.
Working with different types of dehumidifiers.
Each kind of dehumidifier has its working method. In this section, we are going to understand how this unit dry air.
How does absorption dehumidifier works?
Desiccant dehumidifier consists of a rotating desiccant wheel. The fan will suck humid air and made it pass over this wheel. During this, moisture in the air gets absorbed by the wheel. As a result, the wheel becomes wet.
After that, the wet wheel then made dry by the flow of heated air from outside. And, wheels become ready for reuse. This process gets continuous to achieve the required humidity level. In short, desiccant types of dehumidifiers are the best for cold rooms.
How does a refrigerant dehumidifier work?
The compressor dehumidifier consists of an evaporator and condensation coil. Also, it has a compressor for cooling air. The fan pulls humid air over the condensation coil. At the condenser coil, is where humidity in the air get condense. And condensed water stored into the tank. The dry air then pushed out.
Dehumidifier type supplier in Dubai.
Once you decided to buy a dehumidifier, then the next steps to find a supplier. This is the most critical decision which you need to make. Buy a desiccant dehumidifier for an expert company only. Absorption types of dehumidifiers calculation and fixing need experienced hands.
Also, you need to confirm that the company is active in the business. And, it is providing excellent service to their existing clients. Getting a desiccant dehumidifier wheel is a challenging task. So, deal with a company that has the dehumidifier as their core business.
Find the repair center.
The compressor dehumidifier is very easy to repair. However, you need to focus on the service center network and its warranty terms. Many dehumidifier suppliers in UAE, give a warranty for one year. But, the only thing you need to check if they are offering you an on or off-site warranty.
In the case of an on-site warranty, the technician will come to your place to repair the unit. In the case of the off-site term, you need to take the faulty unit to the service center.
