Rooftop air conditioner RTA-3600i

Cooling, heating, dehumidifying: the Mestic RTA-3600i rooftop air conditioner can do it all! Create the ideal climate in your caravan or camper by setting the rooftop air conditioner to a temperature between 18 °C and 30 °C. Suitable for vehicles up to 11 meters long. The inverter technology ensures more consistent cooling and heating.

Roof air conditioner with inverter

With the Mestic RTA-3600i roof air conditioner, you can cool, heat or dehumidify your camping vehicle with efficient inverter technology. Unlike traditional systems that wait until a certain temperature is reached before taking action, this air conditioner uses sensitive temperature sensors to continuously monitor the environment and adjust the airflow and temperature. With inverter technology, the compressor remains active and adjusts its power to the circumstances, which ensures a stable temperature, more comfort and energy savings. In addition, the inverter air conditioners are also quieter and lighter than non-inverter models thanks to the use of a lighter compressor.

The multifunctional air conditioner for campers and caravans has a cooling capacity of 3600 W. It is suitable for vehicles up to 11 meters long. Use the included remote control to easily set the roof air conditioner to a temperature between 18 °C and 30 °C. The air conditioner also has a dehumidification function. This prevents moisture problems such as a musty smell or condensation. Thanks to the compact size of the roof air conditioner, there is still enough space for a solar panel or roof box.

What these air conditioner specs mean for 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 Rooftop Air Conditioner Rta-3600I?

The Mestic RTA-3600I is the high-output option in the range, built for larger motorhomes, twin-axle caravans and anyone who regularly tours in hot climates. Its powerful cooling capacity is designed to cope with bigger interiors, larger window areas and stronger sun without the living space feeling stuffy.

This model is best suited to customers who want residential-style comfort on the road. If you spend long periods abroad, tour year after year or simply prefer a cooler indoor climate whatever the weather, the RTA-3600I gives you the extra headroom you need to stay comfortable across the whole vehicle.
