Hydroxyl Generator Sizing by Volume (IICRC S700)
Sizes occupied-space hydroxyl deodorization by structure volume against a per-unit coverage rating.
Example
You enter
- Structure volume (ft³) 12000
- Coverage per generator (ft³/unit) 6000
- Anticipated continuous run time (days) 3
You get
- Hydroxyl generators needed 2 unit(s)
Checked against published worked examples from: ANSI/IICRC S700 volume-and-coverage sizing.
Details, formula, and sources
ScopeThe generator count and the continuous run-time expectation. The occupied-safe counterpart to ozone shock and thermal fogging - hydroxyl radicals oxidize odor at safe occupied levels but work more slowly. Coverage and run times are manufacturer-specific; remove the source and clean first; the manufacturer and IICRC S700 govern.
Formula or tableunits = ceil(structure_volume_ft3 / unit_coverage_ft3); run continuously for the anticipated days. Occupied-safe; remove the odor source and clean first.
Source and editionVolume-and-coverage sizing, by name; ANSI/IICRC S700. The ceil(volume/coverage) count is a field-arithmetic identity, not edition-bound.
