What the 55L actually does
Helps reduce humidity in larger damp rooms and managed commercial spaces.
The Dri-Eaz 1200 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 conditions associated with mould risk. Results vary depending on 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.

Drying performance depends on site conditions
Even a high-capacity dehumidifier depends on the site.
Warmth, airflow, drainage and containment all affect drying performance. The 55L unit can help, but conditions on site shape the result.
Factor 01
Temperature
Refrigerant output may reduce noticeably below ~15°C.
Factor 02
Airflow
Air movers help direct moist air past wet surfaces.
Factor 03
Moisture load
Larger or wetter areas extend drying time.
Factor 04
Containment
Closed, controlled rooms support better drying performance.
Recommended setup

FAQ
FAQs about 55L industrial dehumidifier hire in London.
Answers to common questions about high-capacity industrial dehumidifier hire London, larger damp rooms, refurbishment drying support, post-leak drying and choosing the right capacity.
What is the 55L industrial dehumidifier suitable for?
The 55L Dri-Eaz 1200 is a high-capacity industrial dehumidifier hire commonly used for larger damp rooms, refurbishment drying support, post-leak drying support (where the source has been resolved), and small commercial spaces such as offices and shops. Hire-grade industrial equipment used on real drying jobs. Drying performance varies depending on temperature, airflow, room size and moisture level.
When should I choose 55L instead of a 20L or 38L unit?
The 55L is the more sensible choice when the affected area is larger than a single room, when the moisture load is heavy, or when longer runs are needed. The 20L Compact Domestic is sized for single rooms; the 38L Broughton CR40 is sized for studio flats and damp rooms; the 55L steps up for larger areas and demanding drying support. Speak to us if unsure.
Can I use it after a leak?
Yes, where the leak source has been fixed and surface water has been cleared. Place the 55L in the affected area and consider pairing with an air mover for soft furnishings. For multi-room flooding, cold sites or whole-property situations, an LGR option such as the 63L Dri-Eaz Revolution may be more suitable depending on conditions.
Can it help with plaster drying?
Yes, 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 fast contractor schedules, an LGR option may be more suitable. Drying time depends on temperature, ventilation, plaster thickness and original moisture level.
Is it suitable for commercial spaces?
Yes, for managed commercial spaces such as offices, shops, small commercial rooms or studio flats. Suitable where the area can be closed off and ventilation managed. Confirm room size, moisture load and access at booking.
Does it need a special power supply?
No. Our 55L Dri-Eaz 1200 hire is supplied as the 230V version — runs from a standard UK 230V supply. No three-phase or specialist wiring is required.
Can it drain continuously?
Yes. The Dri-Eaz 1200 has an automatic condensate pump-out feature. Connected to a sink, gully or floor drain via a drainage hose where supplied, continuous drainage can support longer running periods where set up correctly with a suitable drain.
How long does drying take?
It varies. Drying performance depends on room size, temperature, airflow, 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 air movers as well?
Often yes for post-leak jobs and refurbishment drying. Where carpets, underlay, soft furnishings or plaster are affected, pairing the 55L with an air mover can help direct airflow to the wet surfaces. Ask us if you’d like to add one to the booking.
Is it suitable for cold or unheated spaces?
Refrigerant performance may reduce noticeably below ~15°C. For unheated garages, lock-ups, warehouses or building sites in winter, a Low-Grain Refrigerant option such as the 63L Dri-Eaz Revolution may be more suitable depending on conditions.
Do you deliver across London?
Yes. London delivery and collection are available, subject to access and 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.
Speak to our team before you book
Need help choosing the right drying setup?
Tell us the room size, moisture issue, temperature, access and timeframe — we’ll help you choose a sensible option from the Hireload drying range.
Guidance on this page is general and based on typical high-capacity industrial refrigerant dehumidifier performance (Dri-Eaz 1200, 55L). Drying time and outcomes depend on room size, temperature, airflow, moisture level, the cause of the damp and whether the source has been resolved. A dehumidifier can help reduce moisture but is not a substitute for fixing leaks, removing existing mould or addressing structural damp. For demanding drying jobs, multi-room leaks, cold spaces or any uncertainty about suitability, see our full dehumidifier range or speak to our team.

The 55L step-up — when one Cube isn’t enough
The Dri-Eaz DrizAir 1200 is the workhorse for bigger, wetter jobs: a whole-house flood, a large commercial space, or several rooms at once. It pushes more air (325 m³/h), pumps its water out through a 12 m hose so you can reach a distant drain, and keeps working down to 1 °C. Roll it into place on its wheels, plug into any 13 A socket, and leave it running.
More capacity
Up to 55 L/day peak · around 28–30 L in a real room — a genuine step up from the Cube.
12 m pump reach
Pumps water out to a distant sink or drain, up to ~6 m uphill. No tank to empty.
Roll it room to room
Wheeled build for multi-room jobs. A 36 kg unit — moved on its wheels, not carried.
Works down to 1 °C
Keeps drying in cold spaces where smaller units fade (best above ~15 °C).

Which dehumidifier do I need?
Match the machine to the job — honestly
Litres-per-day ratings are quoted in warm lab conditions; a real UK room gives less. The Cube and the 55L both sit around 28–30 L in the real world — the 55L wins on peak capacity, airflow and pump reach, not on doubling the water. Here’s the straight version.
One-person portable
Cube 43L (F571)
~22 L/day realistic
A single flooded room, a leak, drying-out where access is tight and you carry it up the stairs (22.7 kg).
Best where one room needs drying and you need to carry it in.
Step-up workhorse · this
55L DrizAir 1200
~28–30 L/day realistic · 55L peak
Bigger or several rooms, a whole-house flood, a large commercial space. More airflow, 12 m pump reach, wheeled.
Reach for this when one Cube isn’t enough — and you can wheel a 36 kg unit into place.
Deep / restoration
90L LGR
Lower target humidity
Restoration-grade drying, stubborn deep moisture, lower humidity targets. LGR pulls moisture further down.
Cold rooms below ~15 °C often want a desiccant instead — just ask us.

Using Your 55L Dehumidifier: The 2-Minute Guide
Your machine: Dri-Eaz DrizAir 1200 · 55L class · wheeled · 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 a few minutes.
01
Wheel it into place
Roll it in on its wheels. If it travelled on its side, stand it upright for 30 minutes before switching on.
02
Position it
Firm, level floor — against a wall is fine, with space around the top and back for airflow.
03
Uncoil the drain hose fully
Run the 12 m hose to a sink, drain or gully — fully uncoiled, no kinks, no more than ~6 m uphill. A coiled hose is the number-one cause of leaks.
04
Close windows and doors
Seal the room so the machine dries the air, not the street.
05
Plug in, press ON
Any standard 230V socket, straight to the wall (no extension leads). Press ON on the panel.
06
Give it a minute
The screen shows a short “CMPRSR DELAY” 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
A digital touchpad with a single text display and four keys. There are no warning lights — everything shows as text.
- 1
ON / OFF. Starts and stops the machine.
- 2
Display. Cycles the screen through status and the two hour counters.
- 3
Clear. Clears a message after a power cut, and resets a counter.
- 4
Purge Pump. Empties water out through the hose. It also does this by itself every few minutes.
- 5
Pump-out hose. Water leaves here through the 12 m hose. Keep it fully uncoiled and no more than ~6 m uphill.
- 6
Intake filter. Keep it clear — a clogged filter is a common cause of “no water”.
Messages you’ll see are normal: CMPRSR DELAY (starting up) · DEFROST ON (clearing frost) · PURGE (emptying water)
While it’s running
All of this is normal
Most “it’s broken” calls are one of these six. None is a fault — the machine is doing its job.
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 never switches off
There’s no humidistat — it runs continuously until you stop it. That’s how it’s meant to work on a drying job.
Normal
Warm air blowing out
That’s the drying process. It gently warms the room, which helps it dry faster.
Normal
Screen says “DEFROST”
It’s melting frost off the coil. Water pauses briefly, the fan keeps going, then it carries on.
Normal
“CMPRSR DELAY” at start
A short countdown that protects the compressor. It happens every time you switch on.
Normal
A spurt down the hose
The pump clearing itself out every few minutes. 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 — no tank, it drains through the hose. Otherwise the filter is clogged, or the room is already dry.
The fix
Check water is running from the hose end. Vacuum the intake filter if dusty. Warm air at the top means it’s working.
“There’s water on the floor” / screen says ER9
Usual cause
The hose, almost every time: coiled, kinked, or lifted more than ~6 m. “ER 9” is the blocked-hose code.
The fix
Fully uncoil the hose, drop it below ~6 m of lift, press Purge. Still showing? Switch off, unplug, clear the hose, restart.
“The screen says DEFROST and it stopped making water”
Usual cause
A normal defrost — melting frost off the coil so it can keep working.
The fix
Nothing needed. The fan stays on, water pauses briefly, then it resumes on its own. Constant defrosting means the room is very cold.
“It’s blowing warm air / it won’t switch off”
Usual cause
Both by design — warm dry air is the drying process, and there’s no humidistat so it runs continuously.
The fix
Leave it running. Judge progress with a moisture meter or hygrometer, not by whether it stops.
“It stopped after a power cut”
Usual cause
The power was interrupted. The machine rests before restarting to protect the compressor.
The fix
Wait about 5 minutes and it restarts itself. If a socket tripped, reset the fuse board. Dead with no screen? Call us.
“It’s really noisy / hot air and no water”
Usual cause
A steady hum is normal for a site machine. Fierce hot air with zero water, or a new banging noise, can be a genuine fault.
The fix
Switch off and give us a call — two minutes on WhatsApp with a photo usually tells us whether to swap 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 CMPRSR DELAY? (that’s normal)
- Hose fully uncoiled, no kinks, under ~6 m uphill?
- Intake filter clear?
- Windows and doors closed, warm air at the top?
All yes and still stuck? Two minutes on WhatsApp usually sorts it.
Safety
Five rules — that’s all
- 230V + RCD, no extension leads. Plug straight to the wall. Dry hands; never handle the plug from a wet floor.
- It’s a 36 kg wheeled unit. Roll it — don’t lift it alone. Get help on stairs or into a van.
- Keep it upright and level. If it’s been on its side, wait 30 minutes before switching on.
- Nothing on top, keep it clear. Don’t cover it or block the airflow while it’s running.
- Purge before you move it. Switch off, leave plugged in 10 minutes, press Purge, then unplug and drain the hose.
End of hire
Before we collect — two minutes
- 1
Press OFF. Leave it plugged in for 10 minutes, then press Purge to clear the pump.
- 2
Unplug, disconnect the hose and let it finish draining.
- 3
Coil the cable and hose loosely over the unit; vacuum the filter if it’s easy.
- 4
Leave it upright and dry, wheeled to where we can reach it.
Handed back like this, your deposit goes straight back — no questions, no delays.
Straight answers
The questions people actually ask
Cube 43L or the 55L — which do I need?
In the real world both remove around 28–30 litres a day, so the 55L isn’t “double” the Cube. Choose the 55L for its bigger peak capacity, stronger airflow and 12 m pump reach on larger or multi-room jobs — and when you can wheel a 36 kg unit into place. Choose the Cube when one room needs drying and you need to carry it up the stairs.
What size dehumidifier do I need for a big room or a flood?
For a whole flooded room, a large commercial space or several rooms, the 55L is the sensible workhorse. For very deep or restoration-grade drying, step up to the 90L LGR. For a single tight-access room, the Cube 43L is plenty.
How much water does it really remove?
Up to 55 litres a day at warm, humid lab conditions; in a normal UK room expect around 28–30 litres, tapering as the room dries. That’s the honest figure — ratings are always quoted at their best-case.
Where does the water go — is there a tank?
No tank. A built-in pump pushes water out continuously through a 12 m hose to a sink, drain or gully, up to about 6 m uphill. You never empty a bucket — just keep the hose uncoiled.
How long will it take to dry my property?
A wet room is typically several days; a whole-house flood is often three to six weeks; deep-soaked masonry longer. Fix the source of water first, keep rooms closed, pair with air movers, and judge by a moisture meter rather than the calendar.
Does it work in a cold space?
It keeps running down to 1 °C, better than smaller units, though output drops below ~15 °C. For very cold rooms a desiccant unit is the right tool — tell us the conditions and we’ll point you to it.
