Moisture Control & Ventilation - Crawl Space System
Click on image to learn more
Crawl spaces are a major source of moisture infiltration that permeates up into living areas, emits odors and saturates structures. The crawl space environment is conducive to mold growth and infestation. Foundation vents are inadequate sources of ventilation and do not mechanically expel moisture to keep the area dry and free of odors. In climates like ours in South Carolina the introduction of hot humid air into a cold crawl space environment can create substantial moisture problems.
This Moisture Control and Ventilation (MCV) System - Model # CCC-103 - is designed specifically for homes with crawl spaces. Unlike a conventional crawl space dehumidifier, this MCV System will reduce the humidity and musty odors in a crawl space with controlled ventilation in this problematic area. Because it removes humidity it will also stop wood from rotting and discourage termite infestation, which will go a long way towards eliminating potentially costly repairs.

Specs for the MCV Crawl Space System CCC-103 from Coastal Dry Home:
> Includes Booster Unit, Backdraft Damper and Duct
> Height: 30", Width: 11", Depth: 7"
> Capacity: 3,000 sq. ft. Crawl Space
> Air Flow:
- High Mode: Exhaust - 180 cfm, re-circulating - 180 cfm
- Maintenance mode: Exhaust - 40 cfm, re-circulating - 40 cfm
> Power: 76 watts
Extensive testing conducted by the Department of Energy monitored 12 identical homes to compare crawl spaces with foundation wall vents to closed crawl spaces without foundation vents that utilized mechanical ventilation. Here are the general findings:
> Foundation vents add excess moisture during hot, humid weather, promoting conditions conducive to mold
growth. Is your South Carolina home's crawl space vented?? Ours was and most of them are!
> Vapor barriers by themselves do not keep the crawl space dry enough.
> Closed crawl spaces with mechanical ventilation stay dry all year round.
Foundation-vented crawl spaces have 70% or greater relative humidity a whopping 79% of the time.
Mechanically vented crawl spaces never exceeded 60% relative humidity and there were lower energy costs for heating and cooling the entire house - 17% savings on average!
