Dri-Eaz Cube Dehumidifier Hire — Keeps Drying While You Sleep
Built-in pump, no tank to empty — so drying carries on overnight and while you are out
Mould can start within 24 to 48 hours of a leak, so the hours you lose overnight matter. A dehumidifier with a tank stops as soon as that tank is full. The Cube has no tank — it pumps its own water away through a drain hose, so it keeps running unattended through the night and while you are at work.
Best for flats and single rooms after a leak, damp or condensation — and drying where there is a sink but no floor drain.

What the Cube actually does
Helps reduce humidity in tight rooms and small commercial spaces.
The Cube is a refrigerant industrial dehumidifier — it does not dry walls or remove mould directly. It can help lower a room’s relative humidity so moisture can move out of walls, carpet and plaster into the air, where the unit can collect it.
Bringing a damp space closer to a common comfort range may help reduce condensation, musty smells and the moisture conditions that can contribute to mould growth. Results vary depending on room temperature, airflow, room size and moisture level.
Refrigerant performance varies with room temperature. Output may reduce noticeably below ~15°C. For cold sites and demanding drying jobs, an LGR option may be more suitable depending on conditions. See the larger options below.

01
Isolate the room
Close doors and windows so the unit works on one space.
02
Extract moisture from the air
The Cube can help lower relative humidity in the contained space.
03
Move air across wet surfaces
Pair with an air mover to direct airflow at affected materials.
04
Drain condensate safely
Continuous drainage where set up correctly with a suitable drain.

FAQ
Dri-Eaz Cube Industrial Dehumidifier Hire FAQs.
Answers to common questions about industrial dehumidifier hire, tight-access drying, post-leak drying support and choosing the right capacity.
What is the Dri-Eaz Cube suitable for?
Commonly used by drying contractors for compact industrial drying support — refurbishment work, post-leak rooms (where the source has been resolved), tight-access spaces, hallway drying and small commercial spaces. Hire-grade equipment used on real drying jobs. Drying performance varies with conditions.
Is it better than a domestic dehumidifier?
It is a different class. The Cube is hire-grade industrial (43L/day class at 30°C / 80% RH) used by drying contractors, while the 20L Compact Domestic is sized for a single domestic room. For larger jobs, tight-access industrial drying or refurbishment work, the Cube may be the more sensible choice depending on conditions.
Can I use it after a leak?
Yes, where the leak source has been fixed and surface water has been cleared. Place the Cube in the affected room and consider pairing with an air mover for soft furnishings. For multi-room flooding or whole-property situations, a higher-capacity refrigerant or LGR option may be more suitable depending on conditions.
Can I use it for plaster drying?
It is commonly used for plaster and refurbishment drying support in heated, ventilated rooms (typically above ~15°C) by helping to reduce humidity around wet plaster or paint. For cold rooms or larger schedules, an LGR option may be more suitable. Drying time depends on temperature, ventilation, plaster thickness and original moisture level.
Is it suitable for a cold room or garage?
Refrigerant performance may reduce noticeably below ~15°C. For unheated garages, lock-ups, warehouses or building sites in winter, an LGR option such as the 63L Dri-Eaz Revolution may be more suitable depending on conditions.
Does it need a special power supply?
No. The Cube runs from a standard UK 230V supply. No three-phase or specialist wiring is required.
Can it drain continuously?
Yes. The Cube has an automatic condensate pump-out feature with a 6 m drainage hose. Connected to a sink, gully or floor drain, continuous drainage can support longer unattended runs where set up correctly with a suitable drain.
How long does drying take?
It varies. Drying performance depends on room size, temperature, ventilation, moisture level, the cause of the damp and whether the source has been resolved. We don’t guarantee specific drying times. Speak to us if you’d like advice on sizing for a deadline.
Do I need an air mover as well?
Often yes for post-leak jobs. Where carpets, underlay or soft furnishings are affected, pairing the Cube with an air mover can help direct airflow to the wet surfaces. Ask us if you’d like to add one to the booking.
Do you deliver across London?
Yes. London delivery and collection are available, booked into route slots based on availability. Free collection from our Greenford depot (UB6 7JD) is also available. Kerbside delivery is standard, with indoor placement options where access allows. Confirm at booking.

Which dehumidifier do I need?
Match the machine to the job — honestly
Litres-per-day ratings are quoted in warm lab conditions. In a real UK room you’ll see less, and that’s normal. For most flood, leak and damp jobs in a normal room, the Cube is the one we reach for first.
Smaller job
Compact 20–38L
~8–15 L/day realistic
A single damp room, a bit of condensation, a cupboard or small ensuite. Domestic-to-light commercial.
Best for small, everyday damp. Anything genuinely wet steps up to the Cube.
HIRELOAD COMPACT CHOICE
Cube 43L (F571)
~22 L/day realistic · 43L lab max
A whole flooded room, a burst pipe, drying-out after a leak, new plaster in a warm room. Powerful and reliable, yet compact at 22.7 kg.
Not sure? Start here if you are drying one room or a flat and have a sink or drain point nearby — the all-rounder for tight access and rooms above ~15°C.
Bigger / colder
High-capacity 55–95L
Deep or multi-room drying
Multiple rooms, deep-soaked masonry, restoration-grade drying, or a lower target humidity.
Step up to the 63L LGR — more extraction than the 55L at half the size — or our largest 95L. Cold rooms and cellars below ~15°C often need a desiccant instead — just ask us.
Not sure? Send us the room size and what happened on WhatsApp — we’ll tell you the right unit, not the biggest one.

Using Your Cube Dehumidifier: The 2-Minute Guide
Your machine: Dri-Eaz Cube (F571) · 43L class · pumps its own water out · standard 230V plug
Quick start
Six steps and it’s running
No experience needed. Follow the cards in order — most jobs are set up in under five minutes.
01
Set it down level
It travels flat. If it’s been stood on end, leave it 30 minutes before switching on.
02
Position it
Firm, level spot — middle of the room if you can, 30cm clear all round.
03
Run the drain hose
Clip on the drain hose to a sink, drain or gully. It pumps — so it reaches across the room. No kinks.
04
Close windows and doors
The machine can only dry air it can keep hold of. Seal the room.
05
Plug in, press ON
Any standard 230V socket. Press the ON/OFF key on the panel.
06
Give it a minute
The screen shows a short start-up countdown, then it runs. Warm air out = working. Leave it 24/7.
That’s it. It runs continuously and empties itself — you don’t need to do anything else.
Know your machine
The panel, in plain English
The Cube has a small digital screen and four buttons. There are no warning lights — everything shows as text on the screen.
- 1
ON / OFF. Starts and stops the machine. On shutdown it runs a short drying cycle before it’s safe to move — let it finish.
- 2
Display / Menu. Cycles the screen through status and the humidity setting. Leave it on the default to just run.
- 3
Select / Up. Changes the humidity target, and clears a “Power Failure” message after a power cut.
- 4
Purge Pump. Manually clears water out through the hose. It also does this by itself now and then.
- 5
Pump-out hose. Water leaves here through the long drain hose. Uncoil it fully and keep it free of kinks. The built-in pump lifts water, so the hose does not have to run downhill.
- 6
Intake filter. Pulls damp air in. Keep it clear — a clogged filter is the number-one cause of “no water”.
Messages you’ll see are normal: COMP. DELAY (starting up) · DEFROST (clearing frost) · PUMP PURGING (emptying water) · WAIT FOR UNIT DRYING (shutting down)
While it’s running
All of this is normal
Most “it’s broken” calls are one of these six. None of them is a fault — the screen is just telling you what it’s doing.
Normal
Warm air blowing out
That’s the drying process. It gently warms the room, which speeds things up.
Normal
Screen says “DEFROST”
It’s melting frost off the coil. Water pauses for a bit, the fan keeps going, then it carries on.
Normal
“COMP. DELAY” at start-up
A short countdown that protects the compressor. It happens every time you switch on.
Normal
No water in any tank
There is no tank. It pumps water straight out through the hose, so an empty machine is correct.
Normal
It runs and runs
On a wet job it’s meant to run non-stop for days. Running day and night is what it’s built for.
Normal
A spurt down the hose
“PUMP PURGING” on the screen — the pump clearing itself out. You’ll hear it now and then.
Troubleshooting
Something not right? Start here
Written the way people actually describe it. Each fix takes about a minute.
“It’s not collecting any water”
Usual cause
Nearly always normal: there’s no tank, so it drains through the hose. Otherwise the humidity is set too high, or the filter is clogged.
The fix
Check water is running from the hose end. Set the humidity target to its lowest (or continuous). If the air filter looks blocked, tell us – it is replaced, not washed.
“The screen says DEFROST and it’s stopped making water”
Usual cause
It’s running a normal defrost — melting frost off the coil so it can keep working.
The fix
Nothing needed. The fan stays on, water pauses for a short while, then it resumes on its own.
“It’s blowing warm air — is that right?”
Usual cause
By design. This type of dehumidifier returns warm, dry air to the room.
The fix
Leave it be. The gentle heat helps the room dry faster.
“It stopped after a power cut” / “screen says POWER FAILURE”
Usual cause
The power was interrupted. The machine flags it so you know it happened.
The fix
Press the Select key to clear the message and it carries on. If a socket has tripped, reset your fuse board, wait a moment, switch it back on. Dead with no screen or sound? Call us.
“The screen says ER9 / PUMP BLOCKED”
Usual cause
The most common one, and easily fixed: the hose is kinked, the end is raised too high, or the pump float is stuck.
The fix
Straighten the hose and drop the end below the machine. Press Purge Pump. Still showing? Switch off, unplug, check the pump inlet is clear, then restart.
“There’s water on the floor”
Usual cause
The hose isn’t seated, runs uphill, or the machine was unplugged mid-shutdown and dripped when moved.
The fix
Reseat the hose, uncoil it fully and clear any kinks or trapped loops. Always let “WAIT FOR UNIT DRYING” finish before you unplug or move it.
Drying after a flood on an insurance claim? Photograph your electricity meter before you start — drying electricity is usually reclaimable, and our itemised invoice is accepted by insurers.
Before you call us — the 30-second check
- Screen showing DEFROST or COMP. DELAY? (that’s normal)
- Hose clear, no kinks, end below the machine?
- Humidity set low, or to continuous?
- Windows and doors closed, warm air at the outlet?
All yes and still stuck? Two minutes on WhatsApp usually sorts it.
Safety
Five rules — that’s all
- 230V + RCD. Dry hands when plugging in. Never handle the plug from a wet floor.
- Keep it level and stable. Transport it flat; if it’s been stood on end, wait 30 minutes before switching on.
- Nothing on top. Don’t dry clothes on it and never cover it while it’s running.
- Let it finish shutting down. Don’t unplug during “WAIT FOR UNIT DRYING” or it can drip when moved.
- Switch off and unplug before moving it, cleaning it, or clearing the hose or pump.
End of hire
Before we collect — two minutes
- 1
Press OFF and let “WAIT FOR UNIT DRYING” finish, then unplug.
- 2
Press Purge to clear the pump, disconnect the hose, let it finish dripping.
- 3
Coil the cable and hose loosely over the unit; wipe the filter if it’s easy.
- 4
Leave it level and dry, ready by the door if access is tight.
Handed back like this, your deposit goes straight back — no questions, no delays.
Straight answers
The questions people actually ask
Clear, honest answers for the questions we hear most about hiring an industrial dehumidifier.
How much does it cost to hire an industrial dehumidifier?
The Cube is £39.99 a day, or £74.99 for 3–7 days, with longer hires tapering to £11.20/day. London delivery is from £35. That covers a genuine 43L commercial unit — comparable to what larger firms charge, with clearer pricing.
What size dehumidifier do I need for a room?
For a single small damp room, a 20–38L compact is plenty. For a whole flooded room, a burst pipe or drying-out, the Cube’s 43L is the sensible all-rounder. Multiple rooms or deep-soaked masonry call for a 55–95L unit.
How long will it take to dry my room after a leak or flood?
Surface and air usually clear in a few days; a fully wet room takes considerably longer; deep-soaked walls and floors take longer — we can’t promise a fixed timescale. Fix the source of water first, keep the room closed, and judge by the readings, not by how the air feels.
Can I use it on fresh plaster?
Yes, but dry it gradually. Let fresh plaster firm up for a day or two first, then dry gradually — forcing it bone-dry too soon is what causes cracks. The Cube is well suited to this once the room is warm and sealed.
Does it work in a cold garage or cellar?
Below about 15°C, refrigerant dehumidifiers like the Cube lose output, and near freezing they struggle. For cold spaces a desiccant unit is the right tool — tell us the conditions and we’ll point you to it.
Where does the water go — is there a tank to empty?
No tank. The Cube has a built-in pump that pushes water out continuously through a long drain hose to a sink, drain or gully — so you can reach across a room. You never empty a bucket, just leave it running.
