Overview

ALORAIR built the Sentinel HD35P for crawl spaces and basements, with a pump that moves collected water out through a drain hose. Automatic defrost and memory start reduce hands-on handling, and it carries a cETL listing.

The reason to look at it is the pump and drain hose, which let it run unattended in a place you do not visit. The limit is the capacity data, because the title and spec table give different pint figures.

Who it's for

Crawl space and basement owners, or contractors handling damp structures, will use the pump and defrost feature. Anyone who wants a home appliance with a bucket and a display should look elsewhere.

Pros and cons

Pros
  • Pump moves water out
  • Drain hose supplied
  • Layered refrigeration warranty
Cons
  • Capacity figures conflict in listing
  • Care steps not listed
  • Heavy to move
  • Commercial use positioning

Performance notes

A refrigeration system chills air to collect moisture, and the pump pushes the water out through the hose instead of filling a bucket. Automatic defrost clears frost at lower temperatures, so the unit can run in cool crawl spaces. Memory start brings it back on after power returns.
