Dometic FreshJet FJZ7 3000 Roof Mounted Air Conditioner Features

3000 W Cooling Capacity For Larger Vehicles And Hot Weather Touring

The powerful 3000 W cooling output allows this air conditioning unit for a caravan to cool larger interiors quickly and maintain comfortable temperatures even during warmer European travel conditions.

Inverter Compressor Technology For Quieter And More Efficient Performance

The electronic inverter compressor automatically adjusts operating speed to match cooling demand. This reduces energy consumption, minimises compressor noise and maintains a more stable interior temperature without constant ON/OFF cycling.

Integrated Heat Pump Heating For Year-Round Travel Comfort

The integrated heat pump provides up to 2500–3000 W of heating output depending on operating conditions. This makes the system suitable for spring, autumn and cooler overnight touring without relying entirely on gas heating.
 

Adaptive Power Mode Helps Prevent Campsite Hook-Up Trips

Adaptive Power Mode allows you to set a maximum power draw directly through the Dometic Climate App. This helps the unit operate more reliably on campsites with lower electrical protection and reduces the risk of tripping hook-up supplies.
 

SmartECO Climate Control Supports Off-Grid Touring

When paired with a compatible lithium battery and inverter setup, SmartECO technology intelligently adjusts cooling performance based on available battery capacity. This makes the system more practical for off-grid travel and short overnight cooling sessions.

 

CleanAir Technology Helps Keep Interior Air Fresh

The integrated bipolar ioniser system helps reduce odours, airborne bacteria, mould and allergens inside your caravan or motorhome. This improves interior air quality during longer trips and hot-weather touring.

Frequently Asked Questions

Will The Dometic FreshJet FJZ7 3000 Fit My Caravan Or Motorhome?

The unit fits standard 400 x 400 mm roof openings and is compatible with roof thicknesses between 25 mm and 60 mm. Due to the larger rooftop footprint, roof clearance should always be checked before installation.

Is The Dometic FreshJet FJZ7 3000 Suitable For Off-Grid Use?

Yes — many customers run the system from large lithium battery and inverter setups for shorter cooling periods. Runtime depends on battery size, inverter capacity, ambient temperature and other electrical loads.

What Is The Difference Between The FJZ7 3000 And The Dometic FreshJet FJX7 2200?

The FJZ7 3000 offers significantly greater cooling capacity and is better suited to larger vehicles or hotter climates. It also includes newer inverter technology, quieter operation and improved energy efficiency.

Can The Dometic FreshJet FJZ7 3000 Heat As Well As Cool?

Yes. The integrated heat pump provides efficient heating for cooler evenings, spring touring and autumn travel.

Is Professional Installation Recommended?

Yes. Professional installation is recommended to ensure proper roof sealing, electrical compatibility and adequate rooftop clearance around rooflights, solar panels and accessories.
