If a house is sealed tight with spray foam insulation, it is much harder for moisture to leave the house naturally. While most spray-foam homes are required to have some form of mechanical ventilation (ventilation to ASHRAE 62.2 Standard is recommended), there are many questions on how best to provide it.
Capable of removing up to 105 pints of water a day while using only 4.9 A of energy (8.8 pints per kWh), the Ultra-Aire™ XT105H whole-house dehumidifier is designed for homes up to 2,500 square feet. Optional fresh outdoor air may be ducted to the unit, providing fresh air to dilute pollutants.
The energy recovery dehumidification systems utilize highly efficient passive heat pipe technology. ACT-HP-WA Wrap-Around dehumidification systems can be easily installed in existing or new vertical or horizontal air handlers. The system is designed in a U-shape to wrap around the existing evaporator coil of an HVAC system.
