HOT ! 24 Pint Crawl Space Dehumidifier (CD30-S)

OVERVIEW

Worried About Moisture Damage Below Your Building? This 24 Pint Crawl Space Dehumidifier Removes Excess Humidity for Cleaner Air and Long-Term Protection

Moisture in a crawl space rarely stays contained. Over time, damp air can lead to mold growth, wood rot, musty odors, and higher energy use throughout the building. That’s why crawl space dehumidifiers are used as a long-term solution rather than a temporary fix.

The Ebac USA CD30-S is built to remove excess humidity from crawl spaces and keep conditions stable day after day. By maintaining relative humidity in the 45–55% range, it helps protect structural wood, insulation, ductwork, and other building components that are vulnerable to prolonged moisture exposure. When humidity stays controlled, mold has a harder time taking hold and odors are far less likely to develop.

Air from below the building often finds its way into occupied spaces above. When a crawl space is damp, that air can carry humidity, allergens, and unpleasant smells into living areas, guest rooms, or common spaces. Drying the crawl space supports healthier indoor air, which translates to fewer complaints and a more comfortable environment for occupants.

With a 24-pint capacity, this unit is sized for smaller or moderately damp crawl spaces where consistent moisture control is needed without the cost or power draw of a larger system. Property managers appreciate the balance because it protects multiple buildings without overspending. Landlords use it to reduce maintenance issues and preserve rental value. Hotels rely on it to prevent moisture-related problems from reaching guest-facing areas.

As one of Ebac USA’s commercial dehumidifiers, the CD30-S is designed for continuous operation. The integrated drain connection allows moisture to be removed automatically, eliminating the need for manual emptying and keeping maintenance simple. Once installed, it runs quietly in the background and does exactly what it’s supposed to do.

This unit is especially effective in crawl spaces that remain humid year-round, including encapsulated areas where long-term moisture control is essential. When paired with crawl space encapsulation systems or other commercial air quality equipment, it helps insulation perform better, reduces strain on HVAC systems, and supports overall energy efficiency.

For those comparing crawl space dehumidifiers and evaluating commercial dehumidifiers for below-building use, the CD30-S offers reliable performance without unnecessary complexity. It addresses moisture at its source, helping protect the building, the air above it, and the budget tied to maintaining both.

FEATURES

• 
  24-Pint Typical Moisture Extraction Keeps Crawl Spaces DryWith a typical extraction rate of up to about 24 pints per day at 80°F/60% RH, this unit effectively controls dampness in small to moderate crawl spaces, helping reduce mold risk, odors, and the structural problems that come with excess humidity.
  


• 
  Automatic Moisture Removal With Continuous Gravity DrainageA convenient drain point allows condensate to flow out automatically through a standard hose connection. No bucket to empty and no manual maintenance — critical for hard-to-reach crawl spaces.
  


• 
  Precision Humidity Control You Can Set and ForgetThe built-in adjustable control humidistat lets you dial in the exact humidity level you want to maintain. That means the unit runs only when moisture is present and stops when conditions are balanced, saving energy while keeping crawl space air in the target range.
  


• 
  Hot Gas Defrost for Reliable Operation in Cooler ConditionsFrost buildup can slow or stop a dehumidifier. The hot gas temperature-sensitive defrost system clears frost quickly and keeps the CD30-S running even when temperatures dip.
  


• 
  Rugged Construction for Demanding EnvironmentsThe heavy-gauge steel case and totally enclosed coils protect the system from corrosion and physical wear, especially in damp, tight crawl space conditions. This isn’t a flimsy portable — it’s built to last.
  


• 
  Portable Yet Tough With Built-In HandlesSturdy carrying handles make installation and relocation simple — whether you’re moving between rental properties or positioning it beneath a hotel wing — without sacrificing durability.
