  • Product Overview

    Controlling humidity in confined spaces has never been easier when you use the Dri-Eaz CMC100 Compact Dehumidifier. This Energy Star dehumidifier removes 70 pints of damaging moisture per day from tight spaces, including crawlspaces, storage areas, attics, and basements. In addition, the CMC100—alternatively known as the Dri-Eaz Model F391—excels in commercial and industrial applications such as marine environments, warehouses, and factories.


    Automated Features

    The Dri-Eaz CMC100 Dehumidifier is equipped with many automated functionalities that enable true "set it and forget it" operation. First, this Dri-Eaz dehumidifier controls your humidity automatically without user intervention. Using an onboard digital humidistat, the system maintains your set humidity level by cycling on and off periodically. Therefore, there's no need to continually adjust the dehumidifier settings. This is particularly beneficial if the system is installed in hard-to-reach spaces.

    In addition, the Dri-Eaz CMC100 automatically pumps out collected water using an internal condensate pump. To set up pump operation, simply attach the 10-foot condensate hose (included with the unit) to the system's drain outlet and route the hose to a nearby drain, well, or other type of water receptacle.

    Lastly, the CMC100 features an automatic defrost mode and automatic low temperature protection. In defrost mode, dehumidifier operation stops if frost builds up on the internal condenser or evaporator coils. Once the frost has melted, it will resume normal operation. In low temperature protection mode, the system ceases operation when the temperature falls below freezing. When the temperature rises above freezing, the unit automatically resumes operation. Both modes help protect the CMC100's internal components from damage.

    Flexible Installation

    Along with boasting the shortest vertical clearance of any dehumidifier on the market with a built-in condensate pump, the Dri-Eaz CMC100 Compact Dehumidifier features an interchangeable panel design that allows for multiple airflow configurations. This helps you adapt the system for use on shelves, in small storage areas, and in spaces where standard airflow from the front of the system to the back is not possible. Alternative configurations include:

    • Straight-path design, with air flowing from one end of the system to the other in a tunnel-like fashion.
    • U-shaped design, with the air intake and air outlet located on one side.
    • L-shaped design, with air intake situated on one end of the unit and air outlet on one side.

    Energy- and Cost-Saving Operation

    In addition to maintaining the humidity level in your indoor space, the Dri-Eaz CMC100 Dehumidifier helps protect the outdoor environment. This crawlspace dehumidifier is Energy Star-rated for efficient operation. This means that the system uses 10 to 20% less energy than comparable non-Energy Star dehumidifiers to remove the same amount of moisture. The CMC100 also makes use of R-410A refrigerant, an environmentally friendly refrigerant that will not deplete ozone. Moreover, the system consumes only 5.3 Amps of power while dehumidifying your space.

    Additional Features

    Other features of this Dri-Eaz dehumidifier include:

    • Automatic Restart On Power Failure – Upon a loss of power, the CMC100 will automatically resume operation when power returns.
    • Ductable Air Outlet – This compact dehumidifier features a 6-inch duct collar for ducting applications
    • Washable Air Filter – This washable and vacuum-able air filter helps remove harmful allergens and particles from incoming air.
    • Recessed Handles – Located on the top of the appliance, these handles allow for easy positioning in confined spaces.
    • Leveling Footpads – Four adjustable footpads help stabilize the dehumidifier when it's placed on an uneven surface.

      Hi, I just purchased a Dri-Eaz CMC100 crawlspace dehumidifier to fix my problem. I passed several days on internet to find out which dehumidifier would be the best to buy. I found that this model has many important characteristics that others don't have, such as the condensate pump already installed in the unit.

      With other manufacturers, this pump is not part of the unit and consumers tend to forget about that, therefore,raising the price of the installation, being more complex and not esthetic. It also has a hygrometer with digytal display and several air passage configurations making it the best choice for every situation. I don't want to influence anybody but I think that if anybody spends as much time as me searching for a product, he should look at all of these important features before making a wise decision.

      I bought this unit in September 2009 and placed it into service in my 1400 square ft crawlspace. It worked well for the first ten months. Humidity level went from 68% down to 45% after running for one week. During the summer I noticed the unit was running 24/7. There was a 10% difference in between the actual humidity in the crawl as measured by two hygrometers and the reading on this unit. I called Legend Brands (Dri Eaz) and they had me take it apart and try cleaning it out again. By August 2010 it was running 24x7 and not removing any moisture. My electric bill was up and additional $80 per month. I brought it in to a service center and found out the condenser coil had a crack in it and the refrigerant escaped. They wanted $500 to repair it. Dri Eaz support notified me there was a problem with the sensor in these units that could cause the problems I was having with it running all the time. With some persistence on my part I got them to send me a replacement unit although it took three months of troubleshooting and phone calls to make it happen. They also informed me the replacement unit would have no warranty since I was at the end of the warranty on my original unit.

      The replacement unit they sent me did not work on arrival. I started it up inside my house where the humidity level was 44% and the units gauge reported 63%. It turned on and ran for 3 minutes, turned off for three, and then ran again for another three minutes. This cycle continued for 30 minutes until I unplugged it. When I open up the unit I discovered they sent me another refurbished CMC100 because some of the cooling fins were slightly bent.

      I haven't only been dissatisfied with the CMC100 itself but also Legend Brand's seemingly nonchalant attitude towards making things right and honoring their warranty. I can not recommend this product to anyone and will avoid purchasing a product manufactured by this company for the rest of my life.

          Comments about Dri-Eaz CMC100 Crawlspace Dehumidifier:

          I was impressed at first (one year +/-). Then the coil froze up. I installed new sensors. This time the humidity level it displayed was too low for it to run. I then bought a new board- no difference. I finally brought it to the local distributor. After nearly three months of waiting for new sensors (same ones I replaced) I got it back to find it would freeze up right away. The humidity number was too low also. I finally stuck the freezestat in the coil where the ice forms and placed the humidistat outside the unit in a baggy, partly filled with water. Now it's running, but there is some leakage and obviously I've got the controls all "faked out". It seems the control design is flawed as the other components are OK. Never again!!!

          Works well to reduce humidity in a reasonable amount of time. Have not had it long so I cannot say how it will do in the long run but so far along with sealing off my crawl space it has delivered what it promises.

              The unit has worked great and reduced my crawlspace humidity to 55% within the first 24 hours. It was simple to install. It is too early to say that I would buy this again. If performance continues for next few years I will be sold.

                    Richmond Va., has high humidity most of the year. My heat and air conditioning duct work are in the crawlspace. When humid air infiltrates the crawlspace it attaches and condenses on the ductwork, regardless of insulation. It then drips and forms pools on the plastic ground cover. Reducing the humidity has just about eliminated this problem. Made in USA a plus. Wonderful response from SanteFe to inquiry ref fire hazard? in light of recent press coverage of other dehumidifiers.

Havent had long enough to clean but if its as easy as everything else it will be a piece of cake. Love that you can set % humidity and the pump operates when it needs to. glad I bought this one.

                            I purchased this unit to use in an unfinished basement. It worked OK for about a year and I bought a second unit for a different application. Before the second unit was installed, the first unit failed. Since it was over 1 year I had to pay nearly $400 for labor and refrigerant to have it repaired at the factory repair facility. It then worked for about 8 months and the control board failed. I ordered a replacement and installed it myself. Within 6 months, the unit was again freezing up. Meanwhile, the second unit failed and was repaired under warranty but within 9 months failed a second time.

                            Comments about Dri-Eaz CMC100 Crawlspace Dehumidifier:

                            I ordered this product as an "emergency" solution to a partly-enclosed crawl space which I had not properly vented for the summer months. Upon a recent foray into the crawl space to pull some wires for a home theater upgrade, I noticed water DRIPPING from the joists and insulation.

                            I intended to order the Santa Fe Compact II but they were on backorder and I had to have one immediately, if not sooner, or my year-old, new construction dream home was going to be ruined before it even got broken in!

                            Upon delivery I installed this unit in my crawl space and directed the outlet to a connection I created on an existing HVA/C condensate drain line. Even with a sore shoulder I was able to maneuver the unit into place, stabilize and connect it. Initial rH was almost 80%. Outside rH was around 60%. I ran the unit for a full week and rH dipped to under 60% in the crawl space. Standing water is almost completely gone and the insulation and ductwork is no longer sopping wet and sweating.

                            I like the integrated pump, but my unit advertised it was supplied with a 20' drain tube. The one which was packaged with it was only 10' and I did not have time to return or replace it, so I had to be kind of creative with the unit's placement.

                            The leveling feet are nice, but they do not offer a substantial range of motion, which made setting the unit properly a little challenging.

                            Also, with the outlet being located at the absolute bottom of the unit, it is difficult to provide a "J" or "U" in the outlet tube.

                            My unit also had a small amount of cosmetic damage upon delivery which makes me wonder if it wasn't a remanufactured unit or wasn't compromised in any way during the delivery process. Again, I did not have the time to investigate, I needed it in service immediately.

                            All in all, I think this is a good unit for what I paid and so far has performed as advertised.
