Crawl Space Dehumidifier




The Sentinel HD55 is the perfect device for crawl spaces and basements. With an updated compact design and size, this unit could be easily installed in a low-clearance crawl space or tight basement. Don't be fooled by its appearance; it can remove up to 120 pints at saturation (55 PPD at AHAM). Moisture remains the greatest threat to your home’s structural integrity. Increased indoor humidity levels could cause the growth of mold and mildew and an increase in dust mites, all of which are known allergens that could cause respiratory problems and asthma. This is why you should invest in a dehumidifier today!
