How to choose the right capacity dehumidifier?

Crawlspace and basement series Dehumidifiers

As soon you make up your mind and decide to buy a dehumidifier, start by looking at the space that needs to be dehumidified. This allows you to choose the right ALORAIR Crawlspace & basement series dehumidifiers. This equipment are designed for the market and are meant to help eliminate high humidity in environments that look challenging especially the crawlspace and the basement where mildew and molds grow resulting in musty odors and corrosion. The AHAM equipment have a water capacity of 55 -140pints/day. They give excellent results if the size of the room is between 2,300-8,000sq.ft. They have a unique dual airflow and a horizontal configuration that makes the dehumidifier ideal for basement and crawlspace. Every dehumidifier you buy from ALORAIR are ENERGY STAR qualified and efficient. They work well and will continue to remove water even when the temperatures are low.

How You Can Match the Capacity and the Space Area

To effectively meet capacities including dehumidifying the basement and the Crawlspace, The ALORAIR dehumidifier have moisture removal capacities that range from 55- 140 pints/day (AHAM). So it is necessary that you know how you can choose the right dehumidifier. To be able to do this, you need to look at the size of the space you need to dehumidify and match it with the machine’s capacity. At ALORAIR, we have a simple chart that can help you find the right capacity that can work for you based on the space square footage and the space conditions. So, use this chart which makes it easier for you choose the right size of the dehumidifier. But first, you should know whether space is damp, very damp or moderately damp. Note that the moisture content level will depend on many factors including the number of people that live in the space to be dehumidified, the activities they engage in and their routine. Notice that the more the people who live in a particular space, the more the respiration and the more the moisture. Houses that have low height are susceptible to condensation leading to dampness. After analyzing the space environment, you can then match the environment and the space square footage of your house. You will then need to have a look at a dehumidifier capacity data which gives the capacity and the area it should be used to dehumidify.

The chart below shows the series features to enable you to compare and accurately make a choice:

Observe the Room Condition

Notice that the conditions vary and so you may not stick to the chart before you make a decision on the right dehumidifiers to buy. For instance of you are living in a small space and you are sharing it with multiple people, then too much moisture will be produced through breathing or many of the activities they engage in. Activities such as cooking, baking, taking shower, are likely to increase the amount of moisture in the home. So if any of the conditions stated above are prevalent, it may be necessary that you add the following pints to the equipment that you will finally choose.

  • If the place is near dryers and washers add 5 pints
  • If space has many windows and doors add 5 pints
  • If there are multiple people living in the area and there many routine activities add 5 pints
  • If the place is located in a humid climate, you may need to add 10 pints

Chose a Dehumidifier That Drain by Condensate Pump or Gravity

Dehumidifiers have three types of drain systems. There are those drained by the pump and those that rely on the tank or force of gravity

Dehumidifier with a tank:

They are cheap but will give you a lot of trouble. The tank needs to be cleaned regularly and so they are not suitable for the basement and crawlspace. This unit may not last or serve you for a longer period of time.

Gravity Drain system:

They can be used in the basement or crawlspaces where the pump could be installed and a hose is directed to the pump.

Condensate pump Dehumidifier:

It is an upward draining pump that is ideal if you want to drain the water away from the house. All you need to do is to have a pipe pass through the window and direct it to wherever you want. Pumps have serious issues including detection failure, overheating and rusting. Luckily, at ALORAIR, we have a team of experts who have developed a pump you can rely on for draining. It has a 14.7’ lifting distance and comes with a condensate pump that allows you to drain anywhere.

High COP is designed for energy saving

Before you choose a dehumidifier, you should consider both the price of the equipment and its long term energy consumption. Typically, the conventional dehumidifier will consume more moisture while ALORAIR dehumidifier which is Energy Star Rated saves a lot of energy despite the fact that it purifies the air and dries the dampness. It will help you save not less than $250 per year on energy making it an ideal dehumidifier for a family. The dehumidifier can be deployed for drying and purification tasks and can be relied on to maintain a humidity of less than 50%. Also, there will be no need for you to keep your thermostat at the minimum. It can be used to control humidity and the internal temperatures of the house. It saves you on the expense of purchasing a thermostat and an air purifier.

Internal corrosion protection

ALORAIR humidifiers are made using advanced technology that eliminates Freon leakage and corrosion. It is obvious that the basement and the Crawlspace is home to sulphide, hydroxide, and many other oxides. Freon will leak quickly when it comes in contact with either hydroxide, oxide, sulphide. Also, the coils get corroded when they come in contact with these compounds. As such, it is necessary that they get protected from this. This is why ALORAIR uses an epoxy coating to protect the coils from corrosive environments, increase the coils heat transferability and enhance its lifespan.

HGV-Hot Gas Valve Defrosting System

It offers an efficient defrosting process that makes the dehumidifier to work at a low temperature of about 36 degrease Fahrenheit. It makes the unit to work efficiently and continually. You will not experience periodic stoppage associated with defrosting process as it is the case with other equipment. This saves on energy and allows the unit to give you service for a longer period of time.

Access to the Internal Components

The dehumidifiers from ALORAIR provide and allows for easy access to most of its internal components. The dehumidifier is normally equipped with access panels and come with a pump with quick-connect cables that allow you to easily remove it without having to access the control board. You will also have quick access to the pumps main board. It means that customers can do their own maintenance at home. It makes the process of installing it is simple. It reduces the cost of installation and lowers the general cost of the project.

Bypass Air Design

ALORAIR products have a humidity sensor that helps to eliminate short-cycling. Typically, Basements and Crawlspaces could be sealed as soon as the set level of humidity is satisfied making the dehumidifier to stop. Unfortunately, many of the purifiers we see out there may get wrong signals that make it restart even after it is turned off. What happens, in this case, is that the humidity sensor will be affected by the heat and the wet condition from the internal parts like the evaporator and compressor. It makes the dehumidifier to turn itself on and off periodically. If this is allowed to continue, the dehumidifier will stop working after a year or less.
