How portable are industrial hand push dehumidifiers and what do they weigh?

Industrial hand push units weigh about 33–42 kg at 60–70 L/day, 52–56 kg at 90–120 L/day and 56–70 kg at 150–180 L/day; heavy frames reach 120–160 kg. One person handles up to roughly 60 kg across a flat slab. Above 100 kg plan two people, a ramp or a lift. Doorway width and wheel size decide mobility as much as weight does.
Portability is more than weight
Wheels and casters
Large-diameter wheels cross expansion joints, cable runs and thresholds that small castors jam on. Swivel front wheels help in tight aisles; locking brakes are not optional, because a machine that walks across a slab while the compressor runs will eventually shear its own drain hose.
Handle geometry
Handle height decides whether one person can control 60 kg on a slope. Check it against the people who will actually move it, and check that the machine fits through the narrowest doorway on the route rather than the one nearest the socket.
Drain method
An internal tank keeps the unit self-contained but must be emptied; typical tanks run 5.5–14 litres, which on a 70 L/day machine means several trips a day. Continuous hose drainage, usually 16 mm bore, is standard on industrial sizes.
Power and control
Most mobile units run on single-phase supply drawing roughly 700–1,700 W, so standard industrial sockets suffice. If the machine tipped in transit, allow 2–24 hours upright before starting, and respect the three-minute restart delay after moving.
Choosing weight against capacity
Every kilogram saved comes out of something. Lighter machines typically use smaller compressors and coils, which is why a 33 kg unit might move 680 m³/h while a 69 kg machine moves 2,000 m³/h and offers two duct ports for splitting dry air between adjacent zones. If the job is one room at a time, the lighter unit is the better tool; if it is a long hall, the extra static pressure is worth carrying.
Centrifugal fans rather than axial ones are worth specifying on any unit expected to run against loaded filters or cold, dense air. They hold airflow as conditions degrade, which is exactly when a jobsite machine is asked to perform.
The limits worth knowing
Heavier is not automatically better. Anything above about 100 kg realistically becomes a two-person move, which changes what the machine can be used for: it stops being "roll it over when the room is dry" and becomes "position it once and leave it". Hand push units are also condensing machines, so below roughly 15 °C capacity falls and near 5 °C the coil ices — unheated cold stores need rotor equipment however portable the chassis is.
Representative project configuration
Plaster and screed had to be dry before floor covering. Conditions started at 82% RH with little ventilation and permanent plant was two months away.
Each unit drained through a hose to a riser and ran on a timer. Weight was kept below the one-person limit precisely because it went up a stair core and through 800 mm door openings three times. Drying time varies with screed depth, ventilation and weather; the figure above is configuration-based, not a guarantee.
Weight and capacity bands
| Class | Capacity at 30 °C / 80% | Airflow | Net weight | Realistic handling |
|---|---|---|---|---|
| Compact | 60–70 L/day | 400–450 m³/h | 33–42 kg | One person, single threshold |
| Mid | 90–120 L/day | 840–1,400 m³/h | 52–56 kg | One person on flat slab |
| Large | 150–180 L/day | 1,400–2,000 m³/h | 56–70 kg | Two people or a ramp |
| Heavy duty | 240–360 L/day | 2,000 m³/h and above | 120–160 kg | Mechanical handling, positioned once |
Selection shortcut: match the machine to the route rather than the room. If it has to pass a single doorway every day, buy the largest unit that stays under roughly 60 kg and use two of them; two smaller machines also dry a space more evenly than one large one discharging from a single point. East Dehumidifier publishes the net weight, castor type and doorway clearance for every mobile model for exactly this reason.
