When it comes to caravan or RV life, having a reliable fridge is a game-changer. Whether you’re a weekend warrior or a full-time vanlifer, your fridge needs to keep your food fresh, your drinks cold, and your power usage low. That’s where the Dometic CRX upright fridge shines.
In this article, we’ll dive into what makes the CRX range so popular, how it works, and why it might just be the best fridge you can choose for your mobile lifestyle.
2 Way Fridges vs. 3 Way Fridges for Recreational Vehicles
What Is the Dometic CRX Upright Fridge?
The Dometic CRX series is a line of compressor-powered upright fridges designed specifically for caravans, campervans, RVs, and even marine applications. Unlike traditional absorption fridges that rely on gas or mains power, these fridges use a compressor system similar to your home fridge but optimized for 12V and 24V DC power systems.
This means they are ideal for off-grid adventures where solar panels, batteries, or generators are your power source.
Choosing the right Camping Generator
Why Choose a Compressor Fridge Over a 3-Way Absorption Fridge?
Traditional caravan fridges usually fall into the 3-way absorption category. These can run on gas, 240V mains, or 12V power, but they have some drawbacks:
- Slow cooling speeds
- Higher energy consumption on 12V
- Can struggle in hot weather
- Require proper ventilation at the back
In contrast, compressor fridges like the CRX cool faster, run more efficiently on 12V power, and maintain consistent temperatures regardless of the ambient heat.
Key Features of the Dometic CRX Series
Efficient Compressor Technology
The CRX series uses a variable-speed compressor that adjusts cooling power based on demand. This makes the fridge more energy-efficient and quieter. It only works as hard as it needs to, saving battery life and reducing noise pollution in your caravan.
Runs on 12V, 24V, and 240V
Flexibility is key. The CRX can run off 12V or 24V DC power — perfect for solar-powered setups — and it can also be plugged into mains power at home or powered campsites. It’s a fridge that adapts to your energy source.
Removable Freezer Compartment
One of the coolest features is the removable freezer box. Need extra freezer space for ice cream or frozen meals? Pop it in. Want more fridge capacity? Take it out and enjoy the full space as refrigeration.
Front Ventilation – Easy Installation
Unlike absorption fridges that need rear vents, the CRX series vents from the front. This makes installation easier and more flexible. It also improves cooling efficiency since airflow is not restricted.
Sleek and Practical Design
The upright design fits nicely into caravan kitchens. The stainless steel or black finish looks modern and durable. Plus, the internal LED lighting lets you find your snacks easily without wasting cold air by keeping the door open too long.
Popular Models in the Dometic CRX Range
The CRX range has several models depending on your space and capacity needs:
- CRX65: Compact 65L fridge with a small freezer compartment. Great for campervans or small caravans.
- CRX80: Slightly larger 80L capacity, balancing size and cooling space.
- CRX110: The most popular, offering 108L of fridge space and a 9.5L freezer. Ideal for families or longer trips.
- CRX140: The biggest in the series, with 135L fridge capacity and an 11L freezer. Suited for full-time vanlifers or bigger rigs.
How Much Power Does the Dometic CRX Fridge Use?
Power consumption is a major concern for anyone off-grid. The CRX series is known for being energy-efficient.
On average, a CRX110 draws about 1.1Ah per hour at 240V, which is roughly 26Ah per day under typical conditions. Running it on 12V will have a similar or slightly higher draw, depending on ambient temperature and how often the door is opened.
Thanks to the variable compressor speed, it uses less power when cooling demand is low, saving your battery life.
Installation Tips for the CRX Upright Fridge
Location and Ventilation
Since the fridge vents from the front, you don’t need to worry about wall cut-outs or external vents. However, ensure that the front grille isn’t blocked and gets enough airflow to keep the compressor cool.
Secure Mounting
Upright fridges need to be securely mounted to prevent tipping or damage on the road. Use the mounting brackets provided by Dometic and double-check your cabinet’s fit.
Power Wiring
Make sure to wire the fridge directly to your battery or power source with the correct fuse and cable size to avoid voltage drops. A good-quality DC-DC charger or solar regulator will ensure the fridge runs smoothly off your battery bank.
