Drying equipment sizing

Dehumidifier and air mover counts by class, derated for the conditions you actually measured.

Check the constants before you publish this. The class divisors, air mover spacing, and derating curve at the top of the script are working defaults, not values read out of the standard. Replace them with the figures from your current S500 and this becomes citable.

Affected area

Length (ft)

Width (ft)

Ceiling (ft)

Inside corners and offsets beyond the four basic ones

Class — how much material is wet

Conditions

Affected air (°F)

Affected RH (%)

Reference air (°F)

Reference RH (%)

Coolest surface you care about (°F)

Reference air is whatever you are drying toward — unaffected interior, or outdoor if that is the target. The surface temperature sets the drying goal below.

On the derating number

Nameplate capacity is measured at one set of conditions. The output above is an engineering estimate of what the same machine does in the air you measured — it is not a substitute for the manufacturer's performance curve. Where the two disagree, the curve wins.
