LGR advantage
Why choose LGR for late-stage drying?
Our 55L is rated to work down to about 40% relative humidity. This one is rated to around 20%. That gap is where most drying jobs are won or lost: the room looks dry, the air reads normal, and the plaster, screed or timber is still holding water.
The Dri-Eaz Revolution pre-cools incoming air through a dual coil, so it carries on pulling moisture after a standard unit has stopped being useful. It also weighs 30 kg and stands at roughly half the height of the 55L, which matters when the job is up a staircase or into a loft.
In short. Early in a flood, when the air is soaking, the 55L moves water fast and costs less. Take this one when the job has to be handed over genuinely dry, not just dry-looking.
Compact, stackable footprint
Useful where access, storage or tighter rooms matter alongside drying capability.
Automatic pump-out
Can support longer running periods where drainage is set up correctly with a suitable drain.
Professional drying support
Often chosen for flood, structural, screed and refurbishment drying support.

Common scenarios
Common situations where a 63L LGR may be suitable.
Practical examples — each LGR job is different. Setup, pairing and run length depend on the room and conditions.
Post-flood & post-leak drying support
Often used for: late-stage flood drying support
Commonly used for: drying support after a burst pipe, washing-machine leak or flood — once the source has been resolved and standing water has been cleared. LGR is often chosen here because drying typically continues into the lower-humidity phase.
Pair withAir movers help direct moist air past affected carpets, underlay and soft furnishings.
Screed / build / refurbishment drying
Suitable for: controlled refurb jobs
Commonly used for: drying support during refurbishment — newly poured screed, freshly plastered rooms or fit-out work in controlled conditions where humidity needs to be managed during the schedule.
Check firstAlways follow material drying guidance from the contractor or manufacturer.
Structural & late-stage drying
Often used for: lower-humidity drying phase
Commonly used for: structural drying support — walls, joists, voids and building fabric — particularly where humidity is already dropping and a standard refrigerant unit may be slowing.
May need a different setup ifThe space is very cold or unheated — speak to us before booking so we can recommend the right setup.
Different job?
A 63L LGR isn’t always the right fit.
For occupied dwellings, mild damp, tighter-access compact jobs or very large multi-area floods, a different unit may be more suitable. Same Hireload service approach, with delivery options subject to availability and access. Speak to us if unsure.

Lab rating vs real site
What does “up to 63L” actually mean?
63L
Maximum extraction class Not a guaranteed daily result
Up to 63L/day is a maximum extraction class, not a guaranteed daily output. Actual real-site output depends on temperature, humidity, airflow, room size and moisture load.
LGR is commonly chosen because it can continue supporting drying as humidity drops. For flood, screed or structural drying, pairing with air movers and controlled heat may help where appropriate.
Factor 01
Moisture load
Heavier moisture loads — saturated walls, screeds, soft furnishings — extend drying time and reduce daily extraction figures.
Factor 02
Airflow
Air movers help direct moist air past wet surfaces, supporting better real-site results where set up correctly.
Factor 03
Temperature
Refrigerant performance varies with temperature. Very cold sites can affect output — even with LGR technology.
Factor 04
Containment
Closed, controlled rooms — doors and windows shut where appropriate — typically support better drying performance.

Where 63L sits
When to step up to 63L LGR dehumidifier hire.
Compact, commercial and standard industrial units are commonly chosen for early-stage drying when humidity is high. The 63L LGR (Revolution F413) is often chosen when humidity is dropping, the late-stage drying phase begins, or site conditions are more demanding.

FAQ
FAQs about 63L LGR dehumidifier hire in London.
Common questions about industrial LGR drying hire, late-stage moisture control, and choosing the right capacity.
What is an LGR dehumidifier?
LGR stands for Low-Grain Refrigerant. Unlike a standard refrigerant dehumidifier — which is typically most effective at higher humidity and may slow as the room dries — an LGR unit is designed to support drying into the lower-humidity, later stages. Commonly used where structural or material drying needs to continue beyond the early phase.
When is a 63L LGR dehumidifier usually chosen?
The Dri-Eaz Revolution F413 is commonly chosen for flood and leak drying support, structural drying, screed / build drying and refurbishment work — particularly where the room has already partly dried and a standard refrigerant unit may be slowing down. It can also be a sensible choice for tighter-access jobs thanks to its compact, stackable footprint.
Does it run on a standard UK socket?
Yes. Our 63L LGR hire is supplied as the 230V UK version — runs from a standard UK socket. No three-phase or specialist wiring required.
Is this suitable for flood recovery or structural drying?
It is commonly used for flood / leak drying support and structural drying — once the source of moisture has been resolved and any standing water cleared. For very large multi-area floods, multiple units or a larger building dryer setup may be more suitable. Speak to us so we can size the job before booking.
How long might drying take?
It varies. Drying time depends on room size, temperature, airflow, moisture level, materials affected, and whether the moisture source has been resolved. We don’t guarantee specific drying times.
Do I need an air mover as well?
Often yes for post-leak and structural drying jobs. Where carpets, underlay, walls or soft furnishings are affected, pairing the LGR with an air mover can help direct airflow at wet surfaces. Ask us if you’d like to add one to the booking.
Can it drain continuously?
Yes — the F413 has an automatic pump-out for continuous drainage. Connected to a sink, gully or floor drain via a drainage hose where supplied, it can support longer runs where set up correctly with a suitable drain.
Does it work in cold rooms?
LGR commonly performs better than standard refrigerant in lower-humidity conditions, but very cold sites can still affect performance. For very low temperatures or specialist conditions, please speak to us before booking so we can advise on the most suitable setup.
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. Confirm access and delivery details at booking.
Speak to our team before you book
Need help choosing the right LGR 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 industrial LGR refrigerant dehumidifier performance (Dri-Eaz Revolution LGR F413, 230V). 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 very large multi-area floods, very cold sites or any uncertainty about suitability, see our full dehumidifier range or speak to our team.

Using Your LGR Dehumidifier: The 2-Minute Guide
Your machine: Dri-Eaz Revolution LGR (F413) · 63L class · 230V · automatic pump-out. Set-up takes five minutes — this guide is everything you need.
Read this first
The 60-second countdown is not a fault
Every time you switch it on, the display counts down about 60 seconds (“COMP. DELAY”) before the compressor starts. It is protecting itself while the refrigerant settles. Wait it out — nothing is broken.
Same rule when you switch it off: the display may show WAIT FOR DEFROST or UNIT DRYING while it finishes its shutdown routine. Let it finish — never just pull the plug mid-cycle.
Quick start
Six steps and it’s drying
01
Stand it upright
Travelled on its side? Leave it standing for 30 minutes before you plug in.
02
Position it
Middle of the room if you can, 30cm of clear space around the inlet and outlet.
03
Run the drain hose
Fully uncoiled, no kinks, end secured in a sink, drain or gully. The built-in pump can push water up to 6 metres — but never leave the hose coiled.
04
Close windows and doors
The machine can only dry air it can keep hold of.
05
Plug in and switch on
Standard 230V socket, no extension leads. Then wait out the 60-second countdown.
06
Leave it running
24/7 is the point. It empties itself through the hose automatically — no tank to babysit.
Know your display
What the screen and buttons mean
The numbers
The display cycles through inlet temperature, humidity and running hours. You may also see moisture shown in g/kg — a professional unit, not a percentage. Falling numbers = drying is working.
PURGE button
Manually empties the pump and hose. The machine also purges itself automatically as it runs.
Humidity setting
Out of the box it runs continuously — right for drying jobs. Leave it as delivered unless we have set a target for you.
POWER FAILURE message
Appears if power was cut mid-defrost. Press the menu button to clear it and carry on.
While it’s running
All of this is normal
Normal
60-second countdown at start
Compressor protection delay, every single start. Not a fault.
Normal
Water sounds every few minutes
The pump purging itself through the hose automatically. That is the job.
Normal
Quiet spells now and then
Defrost pauses in cooler rooms — it melts frost off the coil, then carries on.
Normal
Warm air blowing out
That is the drying process. It gently warms the room, which speeds things up.
Normal
Less water after a few days
The space is getting drier. That is success, not failure.
Normal
WAIT FOR DEFROST at switch-off
Its shutdown routine. Let it finish before unplugging.
Troubleshooting
Something not right? Start here
Written the way people actually describe it. Each fix takes about a minute.
“It won’t start — it’s just counting down”
Usual cause
That IS it starting. The 60-second compressor delay runs at every start.
The fix
Wait for the countdown to finish. If nothing happens after it ends, check the plug, the socket and your fuse board.
“The screen says POWER FAILURE”
Usual cause
The machine lost power during a defrost cycle — usually someone unplugged it mid-routine.
The fix
Press the menu button to clear the message. It carries on unharmed. Avoid unplugging while the display shows a defrost or drying message.
“It’s not pumping any water out”
Usual cause
A coiled or kinked hose, the hose end higher than 6 metres, the room already dry — or a blocked pump (screen may show ER9).
The fix
Uncoil the hose fully and check the fall. Press PURGE and listen for the pump. ER9 on screen? Call us — the pump filter needs a rinse and we will talk you through it.
“It leaked when we moved it”
Usual cause
The pump and hose still held water — the machine was moved before purging.
The fix
Before any move: switch off, let the shutdown routine finish, press PURGE, then drain what is left in the hose itself.
“It keeps going quiet”
Usual cause
Defrost pauses — in cooler rooms it stops to melt frost off the coil, on purpose.
The fix
Nothing needed. Warm the room a little and the pauses get shorter.
“The room still feels damp”
Usual cause
Feel is misleading — surfaces dry first, walls and screed release moisture for days. This machine is built exactly for that long tail.
The fix
Keep it running with the room closed. Judge by the falling numbers on the display, not by feel — deep-soaked walls dry at roughly an inch a month.
Before you call us — the 30-second check
- Did you wait out the 60-second countdown?
- Hose fully uncoiled, end below 6 metres?
- POWER FAILURE on screen? Press menu.
- Windows and doors closed?
All four yes and still stuck? Two minutes on WhatsApp usually sorts it.
Safety
Five rules — that’s all
- Straight into the wall socket — no extension leads.
- Keep it upright, always. After travelling on its side, stand it 30 minutes before switching on.
- Let the shutdown routine finish — never pull the plug while the display shows a defrost or drying message.
- Switch off and unplug before touching the hose connections or moving the machine.
- Indoors only, keep the inlet and outlet clear, and never cover it while running.
End of hire
Before we collect — two minutes
- 1Switch off with the button and let the shutdown routine finish on screen.
- 2Press PURGE to empty the pump, then drain what is left in the hose itself.
- 3Coil the hose and cable loosely over the unit.
- 4Unplug, and leave it upright and dry, ready by the door if access is tight.
Handed back like this, your deposit goes straight back — no questions, no delays.
