Smart Features for Day & Night Comfort
Fine-tune your indoor climate with an adjustable temperature range of 16 °C to 30 °C, multiple fan speeds and a convenient night mode for quiet, energy-efficient operation while you sleep. The SPA-3100 also uses eco-friendly R290 refrigerant, offering strong performance with reduced environmental impact.
Reliable Performance on the Road
Powered by a standard 230 V supply, this unit is engineered for dependable use across campsites and touring locations. Compact, quiet and efficient, the Mestic SPA-3100 split air conditioner brings home-style cooling comfort to your caravan or motorhome, wherever the road takes you.
The table above gives you the key technical details at a glance.
Below is a quick guide to what each spec actually means when you’re out on the road,
so you can decide whether this unit is the right fit for your vehicle and camping style.
Cooling capacity (W / BTU)
This is the raw cooling power of the unit.
Higher watts or BTU ratings mean the air conditioner can cope better with larger
interiors, strong sun and hotter climates.
If you travel in southern Europe or park in direct sunlight, prioritise a higher
cooling capacity for faster, more consistent comfort.
Vehicle & interior size
This tells you the size of caravan, motorhome or interior space the unit is designed
to handle. If your living area is larger than the stated guide, the unit will still
cool, but it may take longer to reach and maintain your ideal temperature – especially
in very warm weather or open-plan layouts.
Heating power
Many roof air conditioners also provide heating.
This rating shows how much warmth the unit can deliver when used as a heater.
It’s ideal if you travel in shoulder seasons or through colder nights and want one
compact unit to handle both summer cooling and autumn or spring heating.
Remote control
A remote makes day-to-day use much easier: you can adjust temperature, fan speed and
mode without getting up, which is especially handy at night or when the unit is
mounted high in the ceiling.
Airflow & direction
Airflow describes how the cooled air is distributed through your living space.
Directional vents or adjustable louvers let you point the air where you need it most –
towards the seating area in the day or the sleeping area at night – for more
comfortable, efficient cooling.
Why choose Mestic SPA-3100 Split Air Conditioner for Caravans & Motorhomes?
The SPA-3100 is built around one of the most sought-after features in caravan air conditioning: a genuinely quiet indoor environment. By housing the compressor outside your living space, all the mechanical noise stays out there too, so you get cool, fresh air without the constant hum that portable units produce. At just 53 dB, it's quiet enough to run through the night while you sleep.
Unlike rooftop units, the SPA-3100 requires no roof penetration and doesn't alter the external profile of your vehicle. At just 19 kg total and with IPX4-rated weather protection on the outdoor unit, it's a practical, reversible upgrade that travels with you and installs without specialist help.
The 938 W / 3,200 BTU output keeps caravan and motorhome interiors cool and comfortable, even on warm summer days, and the adjustable temperature range of 16–30 °C means you're always in control. A dedicated night mode automatically reduces fan speed and power draw after dark, so you stay comfortable without disturbing your sleep or running up your electric hook-up.
It runs on a standard 230 V supply, uses eco-friendly R290 refrigerant (GWP 3), and is backed by a 2-year manufacturer's warranty. If you want reliable, whisper-quiet cooling without cutting holes in your roof, the SPA-3100 is the smart choice.
