The Owner's Insights on the Truma Saphir Reverse Cycle Air Conditioner
The Saphir goes in a storage locker, not on the roof. That's the whole point of it. The van keeps its clearance, the ceiling stays clear, and the weight sits low where it belongs instead of three metres up.
It's reverse cycle, so you get 2.4kW of cooling in February and 1.7kW of heating in July out of the same box. Three fan speeds including a sleep mode, and you run it from the remote or from a CP Plus panel if your van already has one.
Two things to plan for. It draws 230 to 240 volts, so you need mains power, a generator or a station that can handle the 20 amp startup surge. And installation is a job for a professional: doing it yourself puts your warranty at risk and it's harder than it looks. Ring us and we'll point you at an installer near you.
Why You'll Love the Truma Saphir Reverse Cycle Air Conditioner
- Fits in your storage locker. No roof unit, so you keep the clearance and the ceiling space.
- 2.4kW cooling and 1.7kW heating. One unit gets you through a Queensland summer and an alpine winter.
- 23.5kg and low mounted. The weight sits down low instead of raising the centre of gravity.
- Three fan speeds with sleep mode. Quiet enough overnight that you'll actually leave it running.
- Remote or CP Plus control. Set a timer so the van is comfortable before you climb in.
- Built-in filters. Dust and allergens get caught before they reach your bunk.
Why You Should Consider a Truma Under Bunk Air Conditioner
Truma have been building caravan climate and comfort gear in Europe for decades, and the Saphir is their under-bunk answer for people who don't want a box on the roof. See the rest of the Truma range.

Why an under-bunk unit instead of a roof unit
A roof-mounted air conditioner adds height, adds wind drag, and puts 30-odd kilos on top of the van where you least want it. The Saphir goes in a storage locker or under a bunk and ducts the air where you need it. You keep the roof clear for solar, you don't lose garage clearance, and the weight sits low. The trade-off is that you give up some locker space and the install is more involved.
Can you run it off a power station?
This is the question we get most. It's a 230-240V unit drawing about 0.98kW in normal running, which is well inside what a mid-sized station can supply. The catch is the startup: 20 amps for 150 milliseconds as the compressor kicks in. You want a station with genuine surge headroom rather than one running at its limit. A unit with 5,000W or more of surge handles it comfortably. Call the store on 03 7056 6732 with your station model and we'll tell you straight whether it will cope, or look through the power station range.
Getting it installed
You can fit it yourself, but we'd talk you out of it. It needs ducting runs, a condensate drain, and a 240V connection done properly, and a self-install puts your warranty at risk. It's a half-day job for someone who does them regularly. Ring the store and we'll point you at an installer in your area rather than leaving you to find one.
Running it overnight
The sleep mode drops the fan to its quietest speed, which is what makes the difference between an air conditioner you use and one you switch off at bedtime. The timer means you can have the van cool before you get back to it. Bear in mind the operating window: it works between 4 and 43 degrees ambient, so it's built for Australian summers rather than a snowfield car park.
What's Included
- Truma Saphir Comfort RC air conditioner
- Remote control
- Intake grille circulation vent, rectangular x 1
- End outlet, black x 3
- End outlet nut, agate grey x 3
- Duct clamp x 3
- 5m of ducting on the ducting variant
What's Not Included
- Professional installation
- CP Plus control panel, if you'd rather not use the remote
- A 240V power source: mains, generator or power station
Pick the variant with 5m of ducting if your installer hasn't already quoted for it. What you still need is a 240V supply, whether that's a powered site, a caravan generator or a power station with enough surge for the 20 amp startup.
Not Sure Which Under Bunk Air Conditioner Suits You?
The Saphir suits you if you want proper reverse cycle climate control in your van without a box on the roof, and you have a locker or under-bunk space to give up. It's the wrong pick if that space is already spoken for, or if you want a plug-in-and-go unit, because this one needs a professional install. Not sure it will fit your van, or whether your power setup will run it? Call the store on 03 7056 6732 and we'll work through it with you before you order.
