Portable air conditioning built for site cabins, welfare units, and temporary offices needing reliable cooling without a fixed installation. The Bosch 9000 BTU Portable Air Conditioner combines cooling, dehumidifying, and fan functions in a single wheeled unit, running on R290 natural refrigerant with an A energy efficiency rating. It covers rooms up to 35 m² (88 m³), suiting single-room site cabins and portable offices rather than large open workspaces.
How 3-in-1 cooling keeps site cabins comfortable without a fixed installation
Fixed air conditioning isn't practical in a site cabin or temporary office that gets relocated or decommissioned once a project ends. Without portable cooling, welfare units and site offices overheat during summer months, cutting into concentration and comfort for anyone working a full shift inside. This unit rolls into place, vents through a single window kit, and runs on three automatic modes, giving cabins and offices working cooling without fixed pipework or professional installation.
Key Features
-
3-in-1 cooling dehumidifying and fan: One unit switches between cooling, moisture removal, and air circulation, covering a cabin's full climate needs without separate appliances.
-
R290 natural refrigerant: A low global warming potential refrigerant that supports environmentally conscious procurement without compromising cooling performance.
-
Three automatic modes: Auto mode adjusts cooling output to the set and ambient temperature, silent mode reduces noise for occupied offices, and sleep mode dims the display for overnight use.
-
Auto swing function: The louvre swings automatically to distribute cooled air evenly across the room rather than in one fixed direction.
-
Integrated handles and castors: Moves easily between cabins or into storage without lifting the full unit weight.
-
A energy efficiency rating: Delivers 2.6 kW of cooling capacity at an EER of 2.6, keeping running costs down over a full site season.
-
Digital display with remote control: LED soft-touch controls on the unit plus a handheld remote with a magnetic holder for convenient operation.

Who is this for
Site managers, site administrators, and facilities teams responsible for keeping site cabins, welfare units, and temporary offices comfortable during warmer months without commissioning a fixed air conditioning system. It suits single-room applications on active construction sites, civil engineering projects, and any temporary accommodation where the unit needs to be relocated as the project progresses.
Typical applications
- Cooling a site manager's office or portable cabin during summer working hours.
- Reducing humidity in welfare units where condensation builds up from occupancy and weather.
- Ventilating a temporary site office when opening windows isn't practical or secure.
- Cooling meeting rooms or induction cabins during site visits and inspections.
- Providing supplementary cooling in facilities plant rooms or small enclosed workspaces.
- Moving between cabins on multi-phase projects as different areas become occupied.
How to use
Step 1: Position the unit on a flat, level surface within reach of a window or external vent point for the exhaust hose.
Step 2: Fit the exhaust hose to the rear outlet and route it through the window venting kit, keeping the hose as short and straight as possible.
Step 3: Connect to a 220-240V single-phase supply and select the required mode using the LED display or remote control.
Step 4: Set the target temperature and fan speed, or select auto mode to let the unit adjust automatically.
Step 5: Empty or check the condensate drainage as instructed in the manual if the unit doesn't self-evaporate under current conditions.
Common mistakes
- Running the unit without venting the exhaust hose outside, which recirculates warm air and reduces cooling effectiveness.
- Positioning the unit too far from the window, forcing a long or bent hose run that restricts airflow.
- Expecting heating performance, this unit provides cooling, dehumidifying, and fan functions only.
- Using the unit in a room larger than 35 m², which leaves it working continuously without reaching the set temperature.
- Leaving the unit unvented in a fully sealed room, causing a pressure imbalance that reduces cooling efficiency.
Safety
R290 refrigerant is mildly flammable, so the unit should be used and stored in a well-ventilated space away from open flames or ignition sources, in line with standard F-Gas handling guidance. The unit is CE and UKCA marked for UK use on a standard 220-240V single-phase supply. Do not use outdoors or in areas exposed to rain or standing water.
Maintenance
Clean or check the air filter regularly to maintain airflow and cooling performance. Wipe the exterior with a dry cloth and avoid solvents on the casing. Store the unit and hose in a dry location when not in use, and check the exhaust hose and window kit seals for damage before each redeployment between cabins.
Frequently Asked Questions
Q: Does this unit heat as well as cool?
A: No. This is a 3-in-1 unit providing cooling, dehumidifying, and fan functions only. It does not include a heat pump or heating mode. For a unit with reversible heating, the Bosch Cool 5100 or the Brittmade 240V 12,000 BTU Portable Air Conditioning Unit provide that function.
Q: Is this unit CE and UKCA compliant, and is the R290 refrigerant safe to use on site?
A: The unit carries both CE and UKCA marking, confirming it meets UK electrical safety requirements. R290 is a natural, low global warming potential refrigerant that is mildly flammable, so it should be used and stored in a ventilated space away from ignition sources. This is standard practice for any R290 appliance and does not require special site permits for typical office or welfare unit use.
Q: What is this air conditioner not suitable for?
A: It's not designed for rooms larger than 35 m², open-plan warehouse space, or permanent ducted installation. It's not weatherproof and must not be used outdoors or in areas exposed to rain. It also does not provide heating, so it isn't a substitute for a heater in cold-weather site accommodation.
Q: Why choose this over a cheaper generic 9,000 BTU unit?
A: Many budget 9,000 BTU units on the market run older refrigerants with higher environmental impact, whilst this unit uses R290 with an A energy efficiency rating and a confirmed 2.6 EER. The three automatic modes, including a genuine silent setting, make it more usable in an occupied office than a single-speed generic alternative.
Q: Does it need a window to vent, and what if the cabin doesn't have one?
A: Yes, the exhaust hose must vent to the outside through a window kit or an equivalent vent point. Without an external vent, the unit will recirculate warm exhaust air and lose most of its cooling effect. Confirm a suitable window or vent point is available in the cabin before ordering.
Q: How long should this unit last with regular site use, and what maintenance does it need?
A: With regular filter checks and dry storage between uses, the unit is built for repeated redeployment across a multi-phase project. Avoid running it in rooms larger than its rated coverage, as continuous overworking shortens compressor life over time.
Q: Can I run this unit on a site generator or standard 240V supply?
A: It runs on a standard 220-240V single-phase supply, the same as most site cabin power provision. If using generator power, confirm the generator delivers a stable single-phase supply, as voltage fluctuation can affect compressor performance on any air conditioning unit.
Q: How quickly can I get this air conditioner delivered to site during a heatwave?
A: Order by 7pm for next-day delivery nationwide on stocked lines. CMT Group operates its own fleet covering over 95% of the UK mainland, with live order tracking and What3Words integration for delivery to a specific cabin, gate, or compound entrance without needing a postcode.
Q: How do I know CMT Group stocks the right cooling equipment for multiple site cabins?
A: CMT Group's EDGE portal lets procurement teams manage bulk orders across multiple cabins and sites from one account, with live stock visibility and contract pricing for repeat equipment needs. This is backed by ISO 9001 and Crown Commercial Service Supplier accreditation, giving procurement teams a documented basis for supplier due diligence.
