Dehumidifiers are units that remove humidity from the air. These units can remove the water in the form of a liquid as in the case of a refrigerant or they can remove the water in the form of a gas like desiccant units. These units have many applications from home uses to large industrial uses.
Dehumidifiers can be used in home basements, garages, and even indoor swimming pools. While home units may be smaller and more compact than industrial units they can effectively control the humidity in these home areas. Sizing a dehumidifier is important because if the dehumidifier is not sized correctly to the space then you will not be happy with the results. It is also important to know the differences in how the units work so that you can choose the one that is appropriate for your application. This is good to know if you are choosing a refrigerant dehumidifier. A standard or commercial refrigerant unit will not be a good choice most of the time because it will not do more than your home air conditioning unit will. If you choose a refrigerant dehumidifier it will almost always be better to go with a low grain refrigerant or LGR unit.
In industrial cases both units can be effective again although the units may be bigger in size than for home uses. The applications they can be used for range from manufacturing, painting, race car builders, libraries, museums, food processing plants, and many others. Just make sure before buying one that you do your homework and that you know what you are buying. All equipment is not made the same and without doing a little homework you may be unhappy with your purchase.
