It can function well even in lower temperatures and will stay secure on the floor because it isn’t mounted on to castors. The unit has shut off protection, so if there’s a power cut when the power returns; it will continue from where it left off and remember the previous settings.
This Meaco model has a great energy-saving function, so once it reaches its target humidity, it switches to fan mode, and thirty minutes later, it checks the humidity again. If the humidity has worsened, then the dehumidifying function will turn back on.
Its energy efficiency will be noticed in your energy bills because it can be run for as little as 5.02p per hour, which can lead to an overall reduction in cost by 80% compared to other models.
The unit will naturally warm the air around it by 10 degrees, so if you’re using it in a naturally cold area such as a garage or conservatory, then it’s great for warming up the area. This desiccant dehumidifier can extract 8 litres of moisture from the air per day which collects into its inbuilt water tank and is suitable for multi-room homes
How do Desiccant Dehumidifiers work?
Desiccant Dehumidifiers work by making use of desiccant material. You may wonder what this is, but this material commonly found in silica gel pouches that you’ll get in consumer goods such as electronics, clothing or shoes.
This material is used because they attract moisture from the air, so they don’t damage your goods. Desiccant material is used in dehumidifiers and is mounted onto a rotating disc. One section of the disc is exposed to the air from the room, and the material extracts the excess moisture.
The disc continues to rotate until it’s blasted with air from the dehumidifier which then forces the moisture into the collecting tank which is then emptied at your convenience making the air in your home higher quality.
This process then repeats to create continuous removal of excess moisture from your living space.
Advantages of a Desiccant Dehumidifier
Desiccant dehumidifiers function using a rotating drum that moves at a slow speed. There are also one or two blowers that pull or push the air through the unit to remove the excess moisture from the air. This means that the only noise generated is by the blowers, which makes Desiccant dehumidifiers have a quiet operation.
Refrigerant alternatives have a compressor makes noise in addition to the sound of the fan, which is significantly louder than a desiccant dehumidifier. The noise of a dehumidifier can be an essential factor when choosing a model, especially when using it in the home because you might need to have it turned on overnight, and you don’t want to be disturbed while you try to sleep.
The parts used to create a Desiccant dehumidifier are lighter than those used to create a compressor alternative. This is mainly due to the compressor and evaporator, which makes up most of the weight of the overall unit.
A desiccant dehumidifier has many plastic components that are naturally lightweight yet durable, so it not unusual for your average unit to weight under 10kg, whereas compressor-style alternatives can weight double this.
Portability is a big factor for most people, especially if you have numerous rooms in your home, so you may want to move it from location to location. Of course, this is even more important if it isn’t mounted onto castors, so you need to ensure that it at least has a carry handle.
Another thing to consider is that compressor based units have a refrigerant component inbuilt which means it needs to remain upright at all times. If you don’t keep it upright, then you’ll need to wait before switching it back on so the refrigerant can settle correctly back into place.
However, Desiccant dehumidifiers can be moved into any position as you transport it without issues.
Can Operate at Lower Temperatures
Traditionally desiccant dehumidifiers are more suitable for lower conditions which are made more evident by the fact that the competing model of refrigerant types aren’t ideal for lower temperature environments.
Refrigerant models require a difference in temperature between the coils and the air for it to function effectively. If the temperature is too low, then the coils inside the dehumidifier begin to free, and if your unit has an anti-frost setting, then this will be activated.
If the temperature continues to fall then, the refrigerant model will designate more energy to defrost instead of dehumidifying so your results won’t be as good.
Desiccant dehumidifiers don’t rely on cooling coils which means that they can deliver reliable and consistent performance at both high and low temperatures.
It’s important to understand that if you’re going to be in environments where the temperature will be under 10 degrees, then a desiccant dehumidifier is more suitable. This is even more so the case in the UK where the weather is unreliable especially if you plan to use it in non-residential home environments such as boats, caravans or garages,
Can Heat your Room
This can be seen as a positive or negative depending on your preferences. Still, desiccant dehumidifiers create excess heat due to their operation, which can be useful by-product to help heat your home.
This is especially useful through the cold winter months, which means that you can save money on your energy bills because you can use it for both dehumidifying and heating purposes.
Some desiccant dehumidifiers also have laundry modes and louvres which allow you to control the direction of the airflow so you can also use them to dry your clothing.
