Portable 4-in-1 Air Conditioning Unit – 12000 BTU - Cooling, Heating, Dehumidifier & Fan

This Portable 4-in-1 Air Conditioner unit (Cooling, Heating, Dehumidifier & Fan – 12000 BTU) is designed for contractors, site managers and facilities teams requiring flexible temperature control in temporary or small to medium-sized rooms.

It offers outstanding versatility with its four different modes: Cooling Mode (Cool), Dehumidification Mode (Dry), Fan Mode (Fan) and Heating Mode (Heat). All of these modes can be operated from the digital soft-touch controls or by using the handy remote control, ensuring easy usability.

This unit provides cooling during warmer months and a 3.3kW heating function for colder periods, making it suitable for year-round use in site cabins, offices, meeting rooms, portacabins and workshop spaces. The dehumidifier function supports moisture reduction in enclosed areas, while the fan-only mode provides air circulation without temperature change.

The 3.3kW heating mode is a proper heater, not a token extra. It's comparable to a medium panel heater and will maintain a comfortable working temperature through a UK winter without a separate appliance. For site managers specifying welfare facilities or portable offices that need climate control across twelve months, that's one unit instead of two, fewer purchase orders, less storage, and less to go wrong.

The self-evaporative system is worth understanding. Standard portable AC units collect condensed water in a tank that someone has to empty, sometimes every couple of hours in humid conditions. This unit recycles that water through the condenser before venting it via the exhaust hose. In most operating conditions, you won't need to drain anything.

The unit is not suitable for outdoor use, spaces without an exhaust point, or rooms above 30m² on a single unit.

Included:

• 1.5m Exhaust hose with an adapter.
• Window sealing plate assembly.
• Remote control with 2xAAA batteries.

✓ All-season solution for temporary buildings and modular environments
✓ Integrated heating mode reduces the need for separate portable heaters
✓ Digital soft-touch control panel with LED display for clear operation
✓ Programmable timer supports controlled temperature management outside working hours
✓ Auto swing function distributes air more evenly across the room
✓ Mounted on castors with integrated handles for easy relocation
✓ Remote control enables adjustment without accessing the main control panel

Is this suitable for site cabins?

Yes. It is suitable for enclosed spaces of approximately 25–30m², including site cabins and temporary offices.

Does this unit provide heating as well as cooling?

Yes. It includes a 3.3kW heating function in addition to cooling, dehumidifying and fan modes.

What does self-evaporative mean?

The system recycles condensed water during cooling to assist internal heat exchange, reducing the need for frequent manual draining under normal conditions.

How noisy is the unit?

It is rated at 65dB (as stated). Suitability depends on room use and background noise tolerance.

What size room will it cover?

It is stated as suitable for rooms between 25–30m².

Is it supplied ready to use?

Yes. It includes an exhaust hose, window sealing kit and remote control with batteries.

Can this replace a fixed HVAC system?

No. It is intended as a portable room solution, not a full-building heating or cooling system.

Can one person move it between locations?

Yes, castors and handles. Unplug, disconnect the hose (push-fit, takes seconds), wheel it where you need it, reconnect. Two people recommended for stairs or rough ground.

How long does installation take?

Under ten minutes. The kit is push-fit and hand-assembled, no tools required.
