Pro-grade dehumidifiers built for workshops, crawlspaces, and job sites — high-capacity units with built-in pumps, WiFi monitoring, and commercial-grade ratings that keep moisture under control where it matters most.
OI pro pick
Sentinel HD55S
Why we picked it: the crawlspace workhorse you’ll spec on repeat — 120 pints a day at saturation, rated for spaces up to 1,300 sq ft, with a gravity drain so there’s no bucket to empty between site visits. ETL-certified, auto-defrost for cold crawlspaces, and backed by a 6-year limited warranty. At $518.93 it’s the default unit for encapsulation jobs and rental turnovers where the dehumidifier just needs to run and not call you.

Sentinel HD35P
Why we picked it: the budget entry that doesn’t skimp on the feature that matters — a built-in condensate pump with a 19.6-foot lift, so it drains where gravity can’t on tight job sites. 70 pints a day, good for up to 1,000 sq ft, in a compact 38-pound box that’s easy to haul through a crawlspace hatch. At $419.49 it’s the cheapest way to put a pumped unit on a job, and the right call for smaller homes and condos.

OI pro pick
Galaxy 60
Why we picked it: the 2025-platform unit that moves the most moisture per dollar — 145 pints a day, 1,800 sq ft coverage, ENERGY STAR certified, and drawing just 4.5 amps on a standard 115V circuit. When a client needs more than the HD55S can cover but the budget won’t stretch to commercial, this is the sweet spot. At $489.76 it’s the new-tech pick for whole-basement drying and medium crawlspaces.

OI pro pick
Galaxy 60P
Why we picked it: everything the Galaxy 60 does — 145 pints a day, 1,800 sq ft coverage — plus a built-in condensate pump, so drainage stops being a site-planning problem. The “no-compromise” homeowner unit that also earns its place on contractor jobs where the only drain is a floor above. At $637.68 it’s the install-and-forget option for clients who won’t check a bucket.

OI pro pick
Galaxy 85P
Why we picked it: the step-up for big, wet spaces — 180 pints a day at saturation (85 at AHAM), rated to 2,300 sq ft, with a built-in pump and internal corrosion protection for damp, unconditioned crawlspaces that eat cheaper units. When the moisture load is serious or the space is just large, this is the homeowner-grade ceiling before you go full commercial. At $899.11 it’s the insurance policy for musty ranches and finished basements.

OI pro pick
Sentinel HD55 (Blue) WiFi
Why we picked it: the only app-controlled unit near $500 — monitor humidity and adjust settings from your phone instead of crawling under the house to read a display. 113 pints a day, up to 1,200 sq ft, with the WiFi readout doubling as remote job-site monitoring for rental properties. At $471.50 it’s the smart-home story that actually earns its keep for landlords and second-home owners.

OI pro pick
Sentinel HDi65S (Black)
Why we picked it: 120 pints a day with a built-in pump, in a matte black finish that disappears into a finished basement instead of shouting “appliance.” Same 1,300 sq ft rating as the HD55S but pump-equipped and compact — the right unit for living-space installs where looks and drainage both matter. At $595.25 it’s the premium compact for homes where the basement is actual living space.

OI pro pick
Sentinel HDi100
Why we picked it: the pro unit — 220 pints a day at saturation (120 at AHAM), rated to 2,900 sq ft, with a commercial-grade refrigeration loop built for continuous duty. When a residential unit would run flat-out and still lose, this is the step up — the one restoration contractors spec for whole-structure drying. At $1,050.00 it’s the “buy once, dry everything” answer for serious moisture loads.

HD35P + Ventirpro 540 Bundle
Why we picked it: don’t just dehumidify — ventilate. The HD35P (70 pints a day, built-in pump) paired with the stainless Ventirpro 540 wall-mount fan moves stale, moisture-laden air out while the dehumidifier wrings out what’s left. The combo approach for crawlspaces with poor natural airflow — 20% off the HD35P + Ventirpro 540 combo, cheaper than buying separately and a complete moisture strategy in one box.

OI pro pick
Galaxy 60P + Ventirpro 540 Bundle
Why we picked it: the “do it right once” package for large crawlspaces — the Galaxy 60P’s 145 pints a day and built-in pump plus the Ventirpro 540’s active ventilation, covering both moisture removal and air exchange in one purchase. At 20% off the Galaxy 60P + Ventirpro 540 combo, it’s the premium bundle, and the one we’d spec for a forever home with a history of damp.
