Create the desired climate in your camping vehicle with the Mestic roof air conditioner RTA-2500L. The roof air conditioner not only cools, but also heats in combination with the integrated heat pump. Simply set the temperature between 16 °C and 31 °C.
Environmentally friendly refrigerant
Cool, heat or ventilate the camper or caravan with the Mestic roof air conditioner RTA-2500L. With a cooling power of 2500 W and a heating power of 2750 W, this air conditioner is suitable for vehicles up to 8 m long. You easily set the caravan air conditioner between 16 °C and 31 °C. Much of the housing is made of polypropylene, a very strong and lightweight material. In addition, the roof air conditioner is compact in size. This leaves enough space on the roof to fit a solar panel or roof box. The refrigerant used in this air conditioner is the very environmentally friendly and efficient R290 gas. This gas has a GWP (Global Warming Potential) of only 3, which is significantly lower than other refrigerants.

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 Rooftop Air Conditioner Rta-2500L White?
The Mestic RTA-2500L offers a clear step up in cooling performance compared to entry-level rooftop units. It’s well suited to medium-sized caravans and motorhomes, or smaller vehicles that often see higher temperatures, helping your interior reach a comfortable climate more quickly after you arrive on site.
Choose this model if you regularly travel further afield or stay on sunny, more exposed pitches. It strikes a strong balance between output, energy consumption and noise, giving you dependable comfort for family holidays and longer summer tours without feeling oversized for everyday use.
