What the AlorAir Storm LGR Actually Is
The Storm LGR Extreme is AlorAir's big commercial dehumidifier, built for the water damage jobs where the moisture load is measured in rooms, not in buckets. Its 180 PPD rating is the extraction spec, pints per day of water pulled from the air under rated conditions, and its LGR design is what keeps that extraction working as the drying progresses. An auto pump moves the condensate out on its own, and the stackable frame lets the fleet scale in the space of one unit. PPD is the tonnage. LGR is the technology, and the pump is the crew it saves.
PPD, pints per day, is the extraction spec of the dehumidifier class, and 180 PPD is the Storm LGR's published number. That is the machine's moisture-removal capacity under rated conditions, the figure the drying plan starts from when the crew sizes the job. More PPD means the room dries in fewer days, and on a water damage job, every day of drying is a day of payroll and a day the building is out of service. The PPD rating is the machine's contribution to the drying schedule. Pints per day is the speed limit of the drying job.
LGR, low grain refrigerant, is the dehumidifier technology that matters on real restoration jobs, because drying is not one humidity level, it is a race to the dry end. Standard dehumidifiers extract well while the air is humid and lose output as the room dries; LGR machines are built to keep pulling water at the low humidity end of the job, which is exactly where the last moisture lives. LGR is the technology that finishes the drying, not just starts it. The last grains of moisture are the hardest to move, and LGR is built for them.
The auto pump is the Storm LGR's answer to the oldest dehumidifier problem: where does the water go? An auto pump lifts the condensate out through a hose to a drain, a sink, or out a window, so the machine runs unattended instead of waiting on a crew member with a bucket. On a commercial job running overnight, the pump is the difference between a machine that works all night and a machine that shuts off full. Auto pump means the dehumidifier runs the shift without a babysitter. The bucket is the most expensive accessory on the job. The pump replaces it.
The stackable frame is the Storm LGR's fleet answer. Two dehumidifiers stacked take the floor space of one, which changes the math for the van, the storage room, and the drying site that needs maximum capacity in minimum footprint. On the big restoration job, the crew stacks the machines and doubles the PPD in the space the floor plan allows. Stacking is how the fleet scales without the trailer growing. Pallet space is money, and the stackable frame spends it once.
The Storm LGR is the freight train of the dehumidifier aisle: it needs room to run, a pallet spot in the van and a place to sit on the job, and it moves tonnage nothing else in the class can match. 180 PPD of extraction, LGR efficiency at the dry end, and an auto pump that keeps the train moving all night. Send the big machine when the job is big, and it earns the space it takes. Tonnage is the point, and the Storm LGR is the tonnage.
- 180 PPD: the published extraction spec of the class leader
- LGR technology: extraction that keeps working at the dry end
- Auto pump: condensate moves itself, so the machine runs unattended
- Stackable build: fleet capacity in one footprint
| Job profile | Storm LGR fit | Why |
|---|---|---|
| Large water damage rooms | Yes | 180 PPD extraction sizes the big load |
| Overnight unattended drying | Yes | Auto pump drains itself through a hose |
| Multi-machine drying layouts | Yes | Stackable frames double up the capacity |
| Small single-room calls | No | The midsize portable class covers those |
The honest trade on the Storm LGR is its size and its lane. It is a big commercial machine, priced and built for the restoration fleet, and the small single-room call does not need its tonnage or its pallet footprint. The BlueDri BD-76 covers the midsize portable lane at 76 PPD, and the Dri-Eaz 2800i answers the premium end with AHAM-rated performance. Buy the Storm LGR for the jobs that need the tonnage, and let the fleet cover the rest. The big machine is the right answer when the job is big enough to ask.
