How to Choose an ALORAIR Dehumidifier

  1. Match Daily Removal Capacity

    Crawl spaces vary significantly in daily moisture levels based on soil dampness and outdoor humidity. ALORAIR rates capacity in total daily pints or saturation pints, ranging from 70 pints up to 198 PPD. Smaller, encapsulated crawl spaces often need only lower-capacity units to maintain proper dryness. Larger subfloors or damp dirt crawl spaces require higher extraction ratings such as 145 or 198 PPD to stay ahead of vapor intrusion. Review the ALORAIR 70-Pint Compact Crawl Space Dehumidifier if you have modest moisture control requirements in an enclosed subfloor.

  2. Select the Drainage Method

    Crawl spaces lack standard sink drains, so water removal method dictates your setup. Gravity drainage routes condensate directly out through a downward-sloping hose, which works only if you have an exterior exit or sump pit lower than the unit drain port. If water must travel upward to reach ground level, a model with an integrated condensate pump is necessary. The ALORAIR 120-Pint Crawl Space Dehumidifier operates via gravity drainage, making it suitable when you can route an unobstructed downward line to a nearby sump basin or floor drain.

  3. Check Energy Star Efficiency

    Subfloor dehumidifiers often run continuously for weeks to manage constant earth evaporation and humidity infiltration. Checking for Energy Star certification helps identify models engineered to maximize moisture extraction per kilowatt-hour of electrical consumption. Certified units maintain dry air conditions while keeping power draw efficient across extended seasonal cycles. If your installation runs non-stop throughout humid months, choosing a certified model minimizes total electrical consumption. The ALORAIR 120-Pint Crawl Space Dehumidifier with Pump carries an Energy Star rating, ensuring efficient moisture removal for enclosed foundation areas.

  4. Evaluate Weight and Access

    Accessing a crawl space typically involves navigating a narrow exterior door or small indoor floor hatch. Unit weight directly affects installation difficulty when carrying the machine through tight entry points. Lightweight models weigh under 40 pounds, allowing straightforward handling by a single person. Larger commercial dehumidifiers can weigh up to 70.5 pounds, requiring multiple people or lifting equipment to position under joists. The ALORAIR 180 PPD Commercial Dehumidifier with Pump weighs 63 pounds, meaning you should verify crawl space access clearance and route paths before maneuvering it into place.

  5. Verify Low-Temperature Defrost Capability

    Unheated crawl spaces experience significant temperature drops during cooler months, which causes moisture on evaporator coils to freeze. Ice accumulation blocks airflow, degrades efficiency, and can trigger safety shutdowns. Selecting a dehumidifier with automatic defrost ensures the refrigeration system actively clears frost before resuming collection cycles. This feature allows continuous humidity control in unconditioned basements and cold dirt subfloors without manual intervention. The ALORAIR 113-Pint Crawl Space Dehumidifier includes automatic defrost capability, maintaining steady moisture extraction during cold conditions without risk of coil freeze-up.

Frequently asked questions

Do you need a built-in pump for an ALORAIR crawl space dehumidifier?

You only need a pump model if you must discharge water above the unit or across a flat run. Models like the Sentinel HDi65 and Sentinel HDi90 include built-in pumps to push condensate upward. If your space features an existing floor drain or downward slope, gravity models such as the Sentinel HD55S drain water naturally without mechanical assist.

Which ALORAIR crawl space dehumidifier is the lightest to carry?

The ALORAIR Helios D35 is the lightest unit on the list, weighing 25.1 pounds. This low weight makes navigation through narrow crawl space access doors significantly easier. Most standard mid-sized models, including the Sentinel HD55S and Sentinel HDi55, weigh 41.7 pounds, while heavy-duty commercial units like the Sentinel HDi90 weigh up to 70.5 pounds.

Can you duct an ALORAIR crawl space dehumidifier to manage multiple areas?

Yes, select models like the Sentinel HDi90 feature ductable airflow configurations. This allows you to channel dry discharge air into isolated crawl space sections or draw damp air from separate subfloor zones. Smaller units, such as the Helios D35 or HS35, use non-ducted direct air circulation designed for open, undivided crawl space layouts.

How do ALORAIR crawl space dehumidifiers prevent internal coil frost in cold weather?

ALORAIR units designed for unheated spaces incorporate automatic defrost cycles to protect internal components. Models like the HD55 Blue, Sentinel HDi55, and Sentinel HD90 detect frost buildup on internal refrigeration coils and automatically clear the ice before resuming dehumidification. This automated feature ensures continuous operation even when unheated subfloor temperatures drop during colder seasons.

Which ALORAIR dehumidifier fits crawl spaces measuring up to 1,800 square feet?

The ALORAIR Galaxy 60 covers crawl spaces up to 1,800 square feet. It provides 145 pints of saturation moisture extraction in a low-profile chassis measuring 11.7 inches high. This low height allows you to position the unit beneath restricted subfloor joists while handling mid-to-large crawl spaces that exceed the coverage of standard 1,200-square-foot models.

Can you monitor an ALORAIR crawl space dehumidifier without crawling under the house?

You can monitor humidity levels remotely by choosing a Wi-Fi-enabled model like the ALORAIR Sentinel HD55S Wifi. This unit includes wireless connectivity so you can track ambient humidity and adjust operational settings directly from a mobile app. It eliminates the need to physically access tight crawl spaces to inspect moisture readings or adjust target humidity levels.

What is the difference between Energy Star and standard ALORAIR models?

Energy Star models, such as the Sentinel HD55S, Sentinel HDi65, and Helios D35, meet strict energy-efficiency guidelines for moisture extraction per kilowatt-hour. These units draw less electricity during continuous operation in humid crawl spaces. Non-rated models still deliver identical moisture removal capacities, but Energy Star certified units help minimize continuous power draw over long operating cycles.
