Truma Air Conditioners

Whisper-quiet Aventa, Saphir and Compact units — German-engineered climate control for caravans and motorhomes

Truma Air Conditioners

Truma is the German-engineered gold standard for caravan and motorhome air conditioning. Famously quiet, efficient, and built to last decades, Truma units are fitted as standard by premium manufacturers like Hymer, Niesmann+Bischoff and Adria — and are the upgrade most UK caravanners aspire to when replacing an older unit. Our full Truma range is in UK stock with fast despatch and manufacturer-backed warranty support.

The Truma air conditioning range

Truma Aventa Compact — the smallest and lightest rooftop unit in the range. Perfect for compact caravans and campervans where roof load is a concern.
Truma Aventa Comfort — Truma's headline rooftop unit, with cooling and dehumidification, optimised for medium-to-large caravans and motorhomes
Truma Saphir Compact and Saphir Comfort RC — locker-mounted units (not rooftop), ideal where you want to keep roof weight down or your van already has a heavy roof load
Truma combi units — heating and cooling in one (see our combi collection)
Truma spares and accessories — filters, condenser covers, vent diffusers, remote handsets

Why Truma costs more — and why it's worth it

Truma units are typically 30–50% more expensive than competitors, but they earn their price tag. Noise levels (44–48 dB at the indoor vent) are among the lowest on the market — genuinely sleepable. Power efficiency is best-in-class, meaning faster cool-down and less drain on your leisure battery or hookup. Build quality is rated for 10+ years of touring use, and the UK parts and warranty network is the most extensive in the leisure industry.

How to choose between Aventa and Saphir

Aventa = rooftop, more powerful cooling, slightly noisier outside (compressor on the roof). Saphir = under-bench / locker, quieter outside, takes up some storage but keeps roof load lower. For most touring caravans, the Aventa Comfort is the right choice. For larger motorhomes already loaded with solar and TV aerials, the Saphir often makes more sense.

For a noise comparison with the main alternative, see our Truma vs Dometic quiet-test and the in-depth Truma Aventa Compact review.

How to Choose the Right Air Conditioner for Your Caravan or Motorhome

Truma is the German-engineered benchmark for caravan and motorhome air conditioning — famously quiet (44–48 dB at the indoor vent), efficient, and built to last 10+ years of touring. The right Truma for you depends on whether you want rooftop or locker-mounted cooling, and the size of your vehicle.

Aventa vs Saphir — rooftop vs locker

The Truma Aventa sits on the roof — most powerful cooling, doesn't take any interior space, but adds 28–35 kg of roof load. The Truma Saphir mounts in a locker or under a bench — quieter outside, lower roof load (important on caravans already carrying solar), but takes up some storage. For most touring caravans, the Aventa Comfort is the right choice. For larger motorhomes heavy on roof load, Saphir often makes more sense.

Compact, Comfort or combi?

The Aventa Compact is the smallest and lightest option — perfect for caravans under 6m. The Aventa Comfort steps up to higher output with dehumidification and is the popular choice for medium-to-large touring caravans. For year-round comfort, the Truma combi range delivers both heating and cooling from a single unit.

Worth the price?

Truma sits 30–50% above the rest of the market — but the price gap usually pays for itself over a decade of touring. See our Truma vs Dometic quiet-test and the Truma Aventa Compact review for real-world comparisons.

Air Conditioner FAQs

Why are Truma air conditioners more expensive than other brands?

Truma units are typically 30-50% more expensive than competitors because of higher-grade components, German-engineered build quality, lower noise levels (44-48 dB), and best-in-class power efficiency. The UK service network is also the most extensive in the leisure industry, which means easier warranty support and parts availability. For most touring caravanners replacing an old unit, Truma is the brand to aspire to - longevity and quietness genuinely justify the price tag.

What's the difference between the Truma Aventa and Truma Saphir?

Aventa units are rooftop-mounted - cooling output is highest and you keep all interior space, but they add 28-35 kg to roof load. Saphir units are locker/under-bench mounted - they keep roof load lower (important on caravans already carrying solar panels) and run quieter outside, but take up some storage space. For most touring caravans, the Aventa Comfort is the right choice. For larger motorhomes already heavy on roof load, Saphir often makes more sense.

Are Truma air conditioners genuinely quieter than Dometic?

Yes - independent dB measurements consistently put the Truma Aventa Comfort at 44-46 dB and the Dometic FreshJet at 47-49 dB at the indoor vent. The difference is small but noticeable when sleeping with the unit running. Truma also tend to have smoother compressor cycling, which prevents the louder on-off "kick" some Dometic users find disturbing.

How long should a Truma air conditioner last?

With normal use and annual filter changes, Truma air conditioners routinely last 10-15 years. The compressors are rated for 30,000+ hours of operation. The most common failure points after a decade are the control board electronics and the fan motor, both of which are still available as Truma spares. Many original Aventa units fitted in the early 2010s are still operating reliably today.

Can the Truma Aventa be installed on any caravan?

Most Truma Aventas are designed for caravans and motorhomes with a roof opening between 360 × 400 mm and 400 × 400 mm. If you have an older Dometic or Truma unit already fitted, replacement is usually a like-for-like swap. For new installations, check your roof thickness (Aventa supports 30-70 mm) and confirm the area has no internal obstructions (ducts, locker walls). Drop us your van's make, model and year and we'll confirm fitment before you buy.

What warranty do Truma air conditioners come with?

Truma air conditioners come with a 24-month manufacturer's warranty when purchased from an authorised UK dealer (which we are). Some products are eligible for an extended 3-year warranty when registered online with Truma within 28 days of purchase. The warranty covers manufacturing defects and component failure, not damage from incorrect installation - which is why we recommend professional fitting for new roof openings.

Will my Truma unit work outside the UK?

Yes - Truma air conditioners are designed for the European market and work across the UK, mainland Europe and beyond. They run on standard 230V mains power available at all European campsites. If you're touring outside Europe, double-check the local voltage and adapter requirements before plugging in.

Are spare parts and filters available for older Truma units?

Yes - Truma maintains spare parts availability for 10+ years after a model is discontinued. Filters are available for current and previous-generation Aventa, Saphir and combi units. If you have an older model and aren't sure which filter you need, message us with the part number from the data plate on your unit (usually inside the housing) and we'll match the correct spare.
