The remaining 25 percent of the air is used to remove moisture from the wheel exiting the unit as warm.
. A desiccant dehumidifier does not work the same way a compressor dehumidifier works. Youve likely seen a small pack of crystals labeled silica gel You find them in boxes cameras computers and other gadgets. They are suitable if you live in South Australia Victoria New South Wales Tasmania or parts of Western Australia where there are four seasons.
The wheel constantly rotates to remove the moisture while a second air stream is heated and pushed through it. These dehumidifiers use evaporators which can be the coiled tube fin and tube and microchannel technology. The unit heats this air to 90 to.
In this case optimal heat recovery can be achieved due to distribution of the air through. Normally 75 percent of the air is dried and sent through the wheel exiting the unit as warm dry process air. To process air that enters the unit it is slowly moved across the desiccant wheel.
The refrigerant dehumidifiers are the type of dehumidifiers that works by the process of condensation to extract moisture from the air. A desiccant is a material that absorbs water. The moisture from the wheel is picked up by the hot.
Desiccant dehumidifiers work to remove moisture more efficiently at lower humidity levels which may be ideal for those living in warmer climates with high humidity during the summer months. A compressor based dehumidifier uses a compressed refrigerant to cool metal coils evaporator coils. They can also reduce indoor air quality and cause damage to materials such as wood or textiles.
To remove this moisture the wheel is in constant rotation and a second air stream is heated and passed through the wheel. How desiccant dehumidifiers work. As warm air holds more moisture than cool air the reactivation air absorbs moisture and vents it from.
True to their name these dehumidifiers pull in air and pass it over a desiccant material such as silica gel. The key factor to consider when choosing between a desiccant or compressor dehumidifier is the climate. Desiccant dehumidifiers work by adsorbing moisture from the process air stream with a large desiccant wheel.
Wet air enter the machine and face the evaporator. Well refrigerant dehumidifiers work by passing warm moist air over a cold evaporating coil dropping the air below its dewpoint temperature and creating condensation from the. The process air and reactivation air.
A blower forces air into the unit and through the rotating desiccant wheel. This mode of operation involves only one common fan for both air flows ie. Engineered for efficiency built to last.
How Does It Work. Dehumidifiers absorb moisture from the air into desiccant materials. Air gets in through one air stream and then leaves through another.
They have very high running costs of around 110 a year and they remove way more water than is required to stop condensation and damp in your home. The whole premise of their operation is a reliance on moisture-absorbing materials most systems of the sort using silica gelCommonly the desiccant material is set up in a rotor form altering layers of sheets that contain the active component being used so that when the air passes through them moisture is transferred for. The hot humid air that enters the dehumidifier condenses on these cool coils.
A small amount of the air enters the unit and is redirected to be used as reactivation air This reactivation air is warmed and transferred over the desiccant wheel typically made of silica gel. The benefit of using a corrugated material is twofold. Desiccant dehumidifiers are a waste of money in domestic applications like in your home.
Desiccant dehumidifiers work by using a large desiccant wheel to adsorb moisture from the process air stream. Dry air blows out the Temp of the outlet will be higher than the intake air. Desiccant dehumidifiers are versatile and work well in both cool and warm climates.
Mode of operation 1 Single fan - Built in internal heat recovery. As the process air is dried the moisture content of the wheel rises. The desiccant material is usually a silica gel or calcium chloride that absorbs moisture from the air leaving the air dry.

The desiccant wheel is nothing but silica gel. In this general overview we discuss our RDDH6000-EH unit and how it worksSmart Family of Cooling Products i. The blower on a desiccant moves the air through the desiccant wheel.
This moisture is then condensed and drained through a duct or stored in a water tank which needs to be emptied periodically. Then dehumidified air through condenser Higher Temp re-drying. The rotor brings the moist desiccant to the reactivation air stream to heat it up.
The core of the rotor is made of a corrugated material that is then impregnated with silica gel on all surfaces. Desiccant or absorption dehumidifiers use a desiccant to absorb water from the air. How does a desiccant dehumidifier work.
In a desiccant dehumidifier the desiccant material is typically a highly-porous silica gel which is rotated within the dehumidifier as moist air is passed over it. Evaporator surface Temp is lower then the condensate water flowing to water plate. As the wheel spins around moist air is blown through one side of the wheel to remove moisture from the air.
The advantage of a desiccant dehumidifier is that. Desiccant dehumidifiers use desiccant material like Zeolite to absorb moisture from the air. Find and Compare the Best Dehumidifiers Based on Price Features Ratings Reviews.
Ever wonder how a desiccant dehumidifier works. Most of the dry air is then expelled back into the space being. Stop browsing online stores for hours - we are doing it for you.

The air to be dried or processed is ducted through the rotor in one air stream. Electric or refrigerant dehumidifiers are the most commonly used dehumidifiers. Desiccant dehumidifiers contain a desiccant wheel with a silica gel surface a drive motor and belt a small heater and a blower.
Refrigerant Compressor type dehumidifier. While refrigerative dehumidifiers may be the most well-known desiccant dehumidifiers also do a great job of keeping a space nice and dry. Q How a desiccant dehumidifier works.
Damp air is drawn into the dehumidifier passing through the slowly turning desiccant wheel where moisture is adsorbed and collected on the silica gel. This leaves the air that exhausts out of the dehumidifier still warm but drier than when it entered. Desiccant dehumidifiers work quite differently.
Converting moist air into dry air inside the unit goes like this. A desiccant dehumidifier works by drawing in moist air and then forcing it through a desiccant material. At Ebac we do manufacture desiccant dehumidifiers.
First the corrugation provides a large surface area for maximum air exposure to silica gel. Most desiccant dehumidifiers utilize a rotary wheel embedded with a desiccant mixture. The silica gel rotor is now the heart of most desiccant dehumidifiers.
