HOW MANY DEHUMIDIFIERS DO I NEED?

DETERMINING HOW MANY DEHUMIDIFIERS TO PLACE DEHUMIDIFIER FACTORS TABLE
1 Determine the cubic footage of the affected area L x W x H CLASS 1 CLASS 2 CLASS 3 CLASS 4 UNITS
2 Note the dehumidifier rating of pint removal at AHAM for LGR's & Conventional Cu ft.
Conventionals. For desiccants, use the process out CFM from the refrigerant 100 40 30 N/A per pint
manufacturer's specifications.

3 Determine the classification of water loss. per pint

4 Check the dehumidifier factors table.
Cu ft. ÷ factor = AHAM pints required (refrigerants) CLASS 1 : wet plywood, concrete, lumber and other dense materials and/or wet carpet pad.
Factor x Cu ft. ÷ 60 = CFM required (dessicants) CLASS 2 : typically whole rooms of wet carpet & pad with water wicking less than 24" up wall
CLASS 3 : whole rooms of wet carpet & pad with water wicking more than 24" where water
* Formulas are intended for initial set up only. has come from above
CLASS 4 : specialty drying with materials containing deep pockets of saturation with slow
evaporation potential
This formula was designed to create a balanced drying system that
achieves a goal of 40% relative humidity or less within 24 hours. ACH = Air changes per hour.
