Dehumidifiers for Water Damage Restoration: Sized to the Loss Class, Not the Square Footage Alone

LGR vs. Desiccant: Pick by Temperature and Vapor Pressure, Not by Habit

Here's what we see constantly: a restoration crew lays out four 70-pint refrigerant units in a 2,000 sq ft Class 3 loss in February, the structural temp is 52°F, and three days later the moisture map hasn't moved. Refrigerant dehumidifiers — including LGR — lose extraction below 65°F because the cold coil ices over. Below that threshold, desiccant is the right call. The Ebac DD400 (197 CFM, 220V) and Bry-Air MiniPAC MP-350 (350 CFM, 11.7 lbs/hr) extract independent of ambient temperature and pull GPP into the 30s where refrigerant units stall in the 60s. The tradeoff: desiccant draws 3–5 kW per unit and needs exhaust ducting for the wet-air discharge. For losses above 65°F structural temp, LGR is faster and cheaper to run.

Sizing for Class 2, 3, and 4 Losses

IICRC S500 baseline is 1 LGR per 1,000 sq ft of affected area for Class 2, tightened to 1 per 800 sq ft for Class 3, and supplemented with desiccant for Class 4. The XPOWER XD-125Li (125 PPD AHAM, 420 CFM, Bluetooth monitoring) and Abatement Technologies AT250RS (266 PPD, 400 CFM) are the standard refrigerant LGR specs for residential and light commercial losses. For multi-room commercial losses, mix two AT250RS units with one Bry-Air MP-1200 desiccant for hardwood and high-density materials where surface drying lags wall cavity drying. The Ebac AD850E (95 PPD, 86V) is the right call for crawl spaces and tight equipment rooms where 110V LGRs trip breakers under starting load.

Pairing Air Movers and Reading the Psychrometric Chart

Four air movers per LGR is the working ratio for standard Class 2 drying — the dehumidifier sets the ceiling, the air movers determine how fast vapor moves from materials to the dehumidifier intake. Track GPP at intake, exhaust, and unaffected reference area twice daily; when intake GPP drops within 5 grains of unaffected, you're at equilibrium and one unit can come off the job. Manufacturer PPD ratings are AHAM (80°F, 60% RH) — real-world extraction at a Class 3 loss in winter runs 40–60% of spec. Size for the actual conditions, not the data sheet. All prices shown — no quote needed.

Sizing for Structural Drying: the Numbers That Matter

Restoration sizing runs on three numbers, not the label rating. First, AHAM pints (measured at 80°F/60% RH): divide the wet space's cubic footage by the class factor in IICRC S500 to get pints of capacity required. Second, grain depression: an LGR unit keeps extracting moisture below the humidity level where a conventional refrigerant unit stalls, which is what finishes a structural dry instead of just starting it. Third, the 24–48 hour window: EPA guidance sets that as the deadline to dry structural materials before mold establishes, which is why crews stage equipment the same day. Units here pump out condensate automatically and restart after generator cycles — the two features that keep a 72-hour dry running unattended.

Frequently Asked Questions

What kind of dehumidifier is used for water damage restoration?
LGR (low grain refrigerant) units are the standard for flooded structures — they keep extracting moisture as the air gets dry, which finishes the job. Desiccant units take over in cold spaces or when target humidity is very low.
How many dehumidifiers do I need for a flooded room?
Size by cubic feet and IICRC S500 class, not floor area alone. A typical Class 2 loss in a 12x20 room needs one mid-size LGR plus air movers. Bigger losses scale by air volume — our team can run the math against your dry logs.
Why do restoration dehumidifiers cost more than home units?
Continuous-duty compressors, condensate pumps, auto-restart, stacking frames, and grain-depression performance that consumer units do not attempt. On an insurance-documented dry, the equipment also has to log stable performance for the file.
Do I need desiccant or LGR for a winter water loss?
Below about 60°F, refrigerant efficiency falls off. Winter losses in unheated structures dry faster with desiccant units, which hold capacity down to -4°F on models we carry.
What size dehumidifier do I need for water damage restoration?
IICRC S500 baseline is 1 LGR dehumidifier per 1,000 sq ft of affected area for Class 2 losses, tightened to 1 per 800 sq ft for Class 3, and supplemented with desiccant for Class 4. Standard refrigerant LGR specs are 125–266 PPD AHAM. Real-world extraction at sub-65°F structural temp runs 40–60% of nameplate, so size for actual conditions, not the data sheet. For a 2,000 sq ft Class 3 loss, plan two AT250RS LGRs (266 PPD each).
How many air movers per dehumidifier on a restoration job?
Four air movers per LGR is the working ratio for standard Class 2 drying. The dehumidifier sets the moisture-removal ceiling; the air movers control how fast vapor moves from wet materials to the dehumidifier intake. Track GPP at intake, exhaust, and unaffected reference area twice daily — when intake GPP comes within 5 grains of unaffected, the structure is at equilibrium and one unit can come off.
