A compact commercial-grade dehumidifier for crawl spaces and basements with a built-in pump and auto defrost for cold spaces. Its capacity at standard test conditions is far lower than the headline figure, so size it on the lower number.

Overview
AlorAir built the Sentinel for crawl spaces and damp basements, packing a commercial compressor into a low metal case that fits under floors. A built-in pump lifts water up and out, while auto defrost lets it work when temperatures drop.
Crawl spaces with no floor drain are where the pump earns its place, sending condensate up to a sink or out a window. Auto defrost suits cold, damp spaces. The headline capacity is measured at saturation, and the standard-condition figure is much lower.
Who it's for
Homes with damp crawl spaces, musty basements or storage areas get continuous, hands-off drying. Bedroom humidity needs a smaller residential unit.
Pros and cons
- Built-in pump for upward drainage
- Works in cold spaces
- Low metal case fits crawl spaces
- Washable reusable filter
- Rated capacity varies by test
- Coarse filter grade
- Remote monitoring is optional extra
Performance notes
Moisture removal depends on temperature and humidity, which is why the unit is rated much higher at saturation than at standard test conditions. Auto defrost pauses the compressor while the fan clears ice, letting it run in cold crawl spaces. The pump lift sets where water can drain.
