  Product Description
The Brunner Polarys TwinAir NG 5200 is a portable split air conditioner built for caravans, motorhomes and campervans where roof-mounted units aren't an option. It delivers 5200 BTU (1520W) of cooling output from a compressor system split across two compact units, one sitting inside the vehicle and one outside, connected by flexible hoses that pass through a partially open window. The result is proper compressor-driven cooling without cutting holes in the roof or paying for professional installation.

How does the Brunner Polarys TwinAir NG 5200 cool a motorhome without rooftop installation?


The TwinAir NG 5200 uses a split design with the 5.6 kg indoor evaporator (45.5 x 17 x 33 cm) and the 14.4 kg outdoor condenser (43.5 x 21 x 35.5 cm) connected by flexible hoses through a window. It draws 580W on 230V mains hook-up to produce 5200 BTU (1520W) cooling, adjustable between 16°C and 30°C.

Splitting the compressor from the indoor unit keeps the loud working parts outside the living space, so the cabin stays quieter than a single-box portable AC. The grey-detailed casing matches modern recreational vehicle interiors, and because nothing is permanently fixed, the whole system packs away at the end of the season or when the vehicle is sold on. It runs from any standard 230V – 50Hz campsite hook-up, drawing 580W, which sits comfortably within a typical 6A pitch supply alongside other low-draw appliances.

Typical owners are caravanners and motorhomers who tour through European summers, campervan converters who don't want to alter their vehicle's structure, and anyone with an existing rooftop AC who needs a secondary cooling option for the back of a larger A-class or fifth-wheel. It's also a sensible pick for owners of older units where adding weight to the roof isn't advisable. The system suits interior volumes in the 25 to 30 m³ range, which covers most touring caravans and mid-size motorhomes.

Frequently Asked Questions


What is the cooling output of the Brunner Polarys TwinAir NG 5200?
The Brunner Polarys TwinAir NG 5200 produces 5200 BTU (1520W) of cooling output. It maintains interior temperatures across an adjustable range of 16°C to 30°C and is designed for leisure vehicle interior volumes of approximately 25 to 30 m³, covering most touring caravans, campervans and mid-size motorhomes.
How is the TwinAir NG 5200 installed in a caravan or motorhome?
The TwinAir NG 5200 is a split air conditioner with two units. The indoor evaporator sits inside the vehicle and the outdoor condenser is positioned outside, with both linked by flexible hoses that pass through a partially open window. No rooftop cut-outs, drilling or permanent modifications are required, and the system can be removed for storage or transfer between vehicles.
What power supply does the Brunner Polarys TwinAir NG 5200 need?
The unit runs on 230V – 50Hz mains electricity with a power consumption of 580W. This is well within the range of a standard 6A or 10A campsite hook-up, allowing it to operate alongside other low-draw appliances such as lights, fridges and chargers without overloading the pitch supply.
What are the dimensions and weight of the indoor and outdoor units?
The indoor evaporator measures 45.5 x 17 x 33 cm and weighs 5.6 kg. The outdoor condenser measures 43.5 x 21 x 35.5 cm and weighs 14.4 kg. Combined system weight is 20 kg. The compact footprint suits placement on a worktop, under a window or alongside a wardrobe in caravans and motorhomes.
Is the Brunner Polarys TwinAir NG 5200 quieter than a single-box portable air conditioner?
Yes. Because the compressor and fan are housed in the outdoor unit positioned outside the vehicle, the noisiest mechanical components are kept away from the living area. The indoor evaporator handles air circulation only, producing a lower interior sound level than a conventional single-unit portable air conditioner where the compressor sits inside the cabin.
Does the Polarys TwinAir NG 5200 provide heating as well as cooling?
No. The Polarys TwinAir NG 5200 is a cooling-only model. Brunner produces a separate variant, the Polarys TwinAir NG Hot & Cold, which adds heat pump functionality from outside temperatures of +10°C and above. For winter use in colder conditions, a dedicated motorhome heating system such as a diesel or gas blown-air heater remains the appropriate solution.
What size of caravan or motorhome interior does the TwinAir NG 5200 suit?
Brunner specifies the TwinAir NG 5200 for interior volumes of approximately 25 to 30 m³. This covers most standard touring caravans, two to four-berth campervans and mid-size motorhomes up to around 7 metres. Larger A-class motorhomes or fifth-wheels may benefit from a second unit or supplementary rooftop cooling.
Can the Brunner Polarys TwinAir NG 5200 be removed and stored between trips?
Yes. The TwinAir NG 5200 is a fully portable split system with no permanent fittings. Both units lift out easily, the connecting hoses detach, and the components pack away for off-season storage or transfer to a different leisure vehicle. This makes it well suited to owners who tour seasonally or who plan to change vehicles in the future.
