Crawl Space Dehumidifiers


Control Moisture and ELIMINATE Mold, Dust Mites, and Wood Rot

Understanding the science of how crawl space humidity and condensation is formed is actually very simple when you understand these Four facts…

  1. Warm air has the capacity to hold much more water than cold air does.
  2. Crawl Space temperatures are cooler because they are below ground level.
  3. Mold grows at a relative humidity of 75% or higher at the surface.
  4. Mold, mildew and fungus grow in damp areas with low lighting and thrive with poor air circulation. These organisms expel a gas that we most commonly associate with a smelly crawl space. Poor air circulation makes the smell worse and allows the spread of mold and mildew to other areas with time.
  5. Mold is a decomposer. Its role in the environment is to consume organic materials and return carbon, which is found in all living matter, back to Earth’s crust. Water and organic matter are absolutely essential for the existence of mold.

When you combine these 5 facts, it’s a recipe for problems in the summer when warm outside air enters the crawl space, and is cooled without taking the water out of it (humidification). The relative humidity in the crawl space goes way up, and condensation forms on windows, water pipes, metal surfaces, ductwork, foundation walls, and crawl space floor surfaces.


Clean + Dry = NO MOLD!

Water is essential for mold growth and high relative humidity levels and water leaks in your crawl space are often associated with mold growth. Once mold growth has begun, high humidity at the surface of an organic food source may be all that is needed to sustain growth. Mold is only an environmental problem when it grows, amplifies, and gets out of control. Mold obtains its nourishment from organic materials such as paper and wood products (cellulose), natural fibers, foods and many soils.


The Climate Chief Solution… The SaniDry CX™ Crawl Space Air System!

The SaniDry CX™ system is a high performance, energy efficient dehumidification system made for cooler temperatures found in basements, with particulate filtration, in a single unit. It’s easy to dehumidify hot air- but basements are cool- the SaniDry CX crawl space dehumidifier is designed specifically for crawl space environments.

It features…

  • A heat exchange core, and much larger cold coil surface area inside than a standard household dehumidifier you would find at your local hardware store.
  • A large blower moves an incredible 300 cfm of air into the machine to dry, and circulates the dry air throughout your crawl space to dry building materials and contents, and makes that damp smell go away!
  • A two-stage high-efficiency filtration systems takes particles as small as 2 microns out of the air- which includes all mold spores!
  • Digital controls- which are easy to use and easy to set the appliance to the desired Relative Humidity  (55%) and the machine does the rest.
  • No more forgetting to empty the crawl space dehumidifier reservoir- The SaniDry CX™ is a self-draining appliance- just like your high-efficiency furnace or boiler.
