Product Details

Alto ducted dehumidifier provides outstanding dehumidification performance and supply the whole room comfort all year round. It is highly flexible to install and silent operation. When installed in a plant room, all the noise will be
absorbed by the wall.

Optional fresh outdoor air may be ducted to the unit via duct, which will provide fresh air to dilute indoor pollutants and maintain high oxygen content in the air. The amount of fresh air ventilation can be regulated by a variety of dampers and controls. And we also supply the optional air conditioning function and energy recovery ventilation function for customized projects.


Principles of operation - AIR to AIR DEHUMIDIFIER

The process of dehumidification involves passing moisture laden air through a dehumidifier where, firstly, the air passes across a refrigerated coil(evaporator). At this point the air is rapidly cooled below its dew point, condensing the water vapour and recovering its latent energy for re-use. The cooled air is then passed across a condenser where it is reheated and returned to the room as warm, dry air.

Q5: How do you care for your kitchen appliances?
A: Keep good Ventilation indoor. Open the doors of the kitchen appliances, if not. There

will be some mildew on cutting board and other kitchenware, because the water vapor can not

evaporate easily.
Keep clean of all the appliances. Each kitchen has its special cleaning fluid,please go to

Kitchen cleaning stores buy some clean them on time.

Q6: Which one do you use the most of kitchen appliances?
A: Assuming you mean small appliances .I say too many! At one time we would buy every one

that came along; including a hot dog machine, pizza maker, elec. carving knife, elec.,

toaster oven,. Most have been garaged sale (sold) or are stored in the garage. Most used;

coffee maker, microwave, blender and mini food processor. OK?

Q:What are the characteristics of a radiation dryer?
The gas heating dryer burns gas and heats the metal or ceramic radiant panel to 400~500 DEG C to produce infrared rays to heat the drying material
Q:What is the principle of a hydrogen dryer?
The adsorption of water in the adsorbent during the regeneration process can be completely eliminated by the thermal diffusion mechanism of high quality regeneration gas (dry gas heating)
Q:What is the mean of dryer?
Most industrial products require drying at some stage of production and require a specific moisture content for processing, molding, or granulation.
Q:What are the functions of a freeze dryer?
The water vapor contained therein is condensed into a liquid drop and discharged by a drainer out of the dryer
Q:What are the factors that affect drying effect of dryer?
In the dryer, the first is to remove the moist air so that it contains very little residual moisture. The air is then heated to decrease its relative humidity. At this point, the steam pressure of the dry air is low. After heating, the water molecules in the particles escape from the bond force and disperse into the air around the particles
Q:What is the principle of a spray dehumidifier?
A device for reducing moisture by blowing a gas through a device to direct contact with a mist of water.
Q:What are the methods of use of the dehumidifier?
The air treatment process of solid moisture absorbent is the process of constant humidity and humidity rising. The dehumidifying method of solid adsorbent is divided into two kinds: static state and dynamic state. Static moisture absorption is to make moist air contact with hygroscopic agent in a natural flow state.
Q:What are the cautions in the use of dryers?
Desiccant should not be placed too much so as not to stain the bottom of the crucible
Q:What are the common types of fluidized bed dryers?
According to the operating conditions, they can be divided into two types: continuous and intermittent
Q:What are the factors affecting the dryer?
The dry hot air transfers heat to the particles in the drying silo, removes moisture from the surface of the particles, and then sends moisture back into the dryer. Therefore, there must be enough air flow to heat the resin to the drying temperature and maintain the temperature for a certain period of time.
