The Complete Guide to Dometic NRX Series Refrigerators: Everything You Need to Know

Discover why the Dometic NRX series is revolutionising mobile refrigeration for campervans, motorhomes, caravans, and marine vessels. From unbeatable energy efficiency to innovative modular design, find out which NRX model is perfect for your adventures.


Introduction: The Next Generation of Mobile Refrigeration

For anyone living or travelling in a campervan, motorhome, caravan, or boat, the refrigerator is arguably the most critical appliance on board. It's the unsung hero that stands between a perfectly chilled drink at sunset and a carton of spoiled milk in the middle of nowhere. When you're miles from the nearest power source, you need a fridge that doesn't just cool—you need one that works smarter, not harder.


Enter the Dometic NRX series: Dometic's latest and most advanced line of compressor refrigerators, designed specifically for people on the move. Replacing the popular CRX series, the NRX represents a significant leap forward in mobile refrigeration technology, combining industry-leading energy efficiency with innovative features that solve the real-world challenges of off-grid living.


In this comprehensive guide, we'll explore everything you need to know about the Dometic NRX series—from the different model variants and their unique features to the technical specifications that matter most. Whether you're fitting out a new build or upgrading an existing setup, this guide will help you choose the perfect Dometic NRX refrigerator for your adventures.


8 Reasons the Dometic NRX Series Is a Game-Changer for Mobile Living


What makes the NRX series stand out from other mobile refrigerators? Here are eight compelling reasons why this new range is setting the standard for off-grid refrigeration:


1. Up to 25% More Energy Efficient

The single most impactful improvement in the NRX series is its exceptional energy efficiency. These refrigerators consume up to 25% less energy than comparable models—and approximately 9% better than even the successful CRX predecessor series. While that number might sound modest on paper, its real-world impact is massive for anyone relying on a limited battery supply.


This isn't just an abstract percentage; it's another day of solitude by the lake, an extra night stargazing in the desert, or the confidence to push deeper into the backcountry without a generator shattering the peace. With energy consumption as low as 0.22kWh per 24 hours on some models, the NRX series directly extends your ability to stay off-grid longer.


2. Revolutionary Removable Freezer Compartment

In a compact mobile space, every inch counts. The Dometic NRX series introduces a brilliant modular design feature: the entire freezer compartment can be completely removed. This patented Dometic invention gives you unprecedented control over your cold storage.


The practical benefit is immediate. Heading out for a weekend and need more space for fresh produce than frozen goods? Just pull the freezer out and instantly transform the entire unit into a larger-capacity refrigerator. Going on a longer trip requiring frozen food storage? Simply reinsert the freezer compartment. This 3-in-1 cooling solution—refrigerator, freezer, or both—moves beyond the one-size-fits-all approach, empowering you to configure your appliance to match the specific needs of each journey.


3. Three Intelligent Operating Modes

The NRX series features a premium smart compressor with three distinct operating modes, all controlled via an intuitive touch control panel:


  • Eco Mode: Prioritises low energy consumption, ideal for extended off-grid use while maintaining reliable cooling performance.
  • Performance/Boost Mode: Delivers rapid cooling when you need to chill contents quickly after a shopping trip or in hot weather conditions.
  • Quiet/Silent Mode: Reduces noise to a minimum (40-45dB), perfect for sleeping areas or when you want peaceful evenings.


This flexibility allows you to tailor the refrigerator's operation to your specific situation, whether you're prioritising battery life, cooling speed, or a peaceful night's sleep.


4. Clever Winter Ventilation Function

One often-overlooked challenge with mobile refrigerators is what happens when they're not in use. The NRX series includes a thoughtful dual-function lock system that also acts as a ventilation mechanism. When the fridge isn't in use—during winter storage or between trips—you can engage the vent function to prop the door slightly ajar, promoting air circulation and preventing moisture build-up, mould growth, and unpleasant odours.


This small detail demonstrates Dometic's understanding of real-world mobile living, where appliances need to work well not just when running, but also during the off-season.


5. Eco-Friendly Refrigerant

Appliances built for the road need to be tough, but the NRX series proves that rugged performance and environmental responsibility don't have to be mutually exclusive. The series uses eco-friendly refrigerant to deliver high-performance cooling while meeting the latest environmental regulations.


This feature highlights a welcome shift in the industry, allowing you to explore the outdoors with a lighter conscience. The newer models use R1234YF refrigerant combined with vacuum insulation panels (VIP) for improved performance—technology that benefits both efficiency and environmental impact.


6. Lighter, Smarter Construction

Through intelligent design and smarter use of materials, Dometic has reduced the overall weight of the NRX refrigerators. This makes them easier on your vehicle while still being built to withstand the vibrations and demands of travel. The bevelled rear side design also ensures optimal utilisation of space on board, maximising storage potential in tight installations.


Every gram matters in mobile applications, especially for smaller campervans where payload limits are a constant consideration. The lighter construction of the NRX series helps you carry more of what matters—whether that's water, gear, or simply keeping your vehicle within legal weight limits.


7. Universal Installation Flexibility

The NRX series is designed for straightforward installation with features that adapt to virtually any layout:


  • Reversible door hinge: Can be fitted left or right as required, accommodating any kitchen configuration.
  • Standard or flush-mount frames: Optional installation frames available as accessories for a seamless, professional finish.
  • 12/24V DC operation: Compatible with standard vehicle electrical systems, with AC adapter options available.
  • Backwards compatible: NRX fridges are largely reverse compatible with discontinued CRX series installations (with minor dimensional changes).


8. Premium Build Quality and Thoughtful Details

From the elegant frameless door with full-width handle to the LED-lit interior with IR sensor, the NRX series exudes quality. The rearrangeable shelves, dual crisper drawers, bottle holders, and door trays make organisation effortless. A new secure locking mechanism clicks firmly into place, giving you peace of mind that the door will remain shut while you're bouncing down rough tracks.


The touch control panel with integrated LED light bar provides intuitive operation and visual feedback on compressor status, making it easy to monitor and adjust your fridge at a glance.

Can I replace my old Dometic CRX fridge with an NRX model?
Yes, Dometic NRX refrigerators are largely backwards compatible with CRX series installations. The NRX 50 replaces the CRX50, NRX 60 replaces the CRX65, NRX 80 replaces the CRX80, NRX 115 replaces the CRX110, and NRX 130 replaces the CRX140. However, there are minor dimensional differences, so you should measure your existing cutout carefully and compare with NRX specifications before ordering. Some customers report the NRX is slightly wider than the CRX, which may require minor cabinet adjustments.

How much power does a Dometic NRX fridge use?
Dometic NRX refrigerators are highly energy efficient, consuming up to 25% less power than comparable models. Typical power consumption ranges from 0.22kWh to 0.48kWh per 24 hours depending on the model size and operating conditions. The compressor draws approximately 50-55 watts at 13.5 volts when running. For example, the NRX 115C draws approximately 1.27Ah per hour on average. Using Eco mode further reduces energy consumption, making these fridges ideal for off-grid use with solar panels and leisure batteries.

What voltage does the Dometic NRX run on?
All Dometic NRX models operate on 12V or 24V DC power, making them suitable for vehicles, boats, and leisure batteries. The NRX-E, NRX-C, and NRX-T series are DC-only with bare wire connections for direct battery wiring. The NRX-S marine series includes AC/DC capability with a plug for shore power connection. For other models, you can purchase the Dometic DPS-R 135W Mains Adaptor separately to enable 100-240V AC operation when connected to hookup or shore power.

How do I remove the freezer compartment on my Dometic NRX fridge?
The freezer compartment on NRX-C and NRX-S models is designed to slide out easily without tools. Simply pull the freezer compartment straight out to remove it, which converts the entire interior into a larger refrigerator or freezer space. To reinstall, slide the compartment back into its guides until it clicks into place. Dometic also sells replacement shelves specifically designed to fill the space when the freezer compartment is removed, allowing you to maximise storage capacity.

What ventilation clearance does a Dometic NRX refrigerator need?
Dometic NRX refrigerators require a minimum clearance of 50mm (2 inches) on all sides for proper air circulation. This includes clearance at the rear, sides, and top of the unit. Insufficient airflow results in reduced cooling performance and shortened lifespan. The unit should be installed on a level surface, away from direct sunlight and heat sources. The maximum tilt angle during operation is 30 degrees, and the maximum operating time when tilted is 2 hours.

Can I change the door hinge on my Dometic NRX from left to right?
Yes, all Dometic NRX refrigerators feature a reversible door hinge that can be configured for either left-hand or right-hand opening. The fridges are delivered right-hinged as standard, but you can easily change them to left-hand hinge. The process involves removing the bottom hinge, lifting the door off, transferring the top hinge to the opposite side, moving the door handle and latch mechanism, then remounting the door. Full instructions are provided in the installation manual.

What is Winter Mode on the Dometic NRX and when should I use it?
Winter Mode is available on larger NRX models (NRX 115 and NRX 130) and is designed for operation at low ambient temperatures below 16°C. When cold air impacts the cooling unit's performance, activating Winter Mode helps maintain proper freezer compartment temperatures. You should deactivate Winter Mode when ambient temperatures rise above 16°C to avoid higher power consumption. Additionally, the dual-function door locks allow you to prop the door slightly ajar during storage to promote ventilation and prevent mould or odours when the fridge is not in use.

What is the warranty on Dometic NRX refrigerators?
Dometic NRX refrigerators come with a manufacturer warranty. The warranty covers defects in materials and workmanship but does not cover damage from incorrect installation, improper voltage, incorrect maintenance, use of non-original spare parts, unauthorised modifications, or misuse. For warranty claims, you need to contact the manufacturer's branch or your retailer with proof of purchase and a description of the fault.

Why is my Dometic NRX fridge not cooling properly?
If your NRX isn't cooling properly, check these common causes: ensure there's adequate ventilation with at least 50mm clearance around the unit; verify the door seal is intact and closing properly; check that vents aren't blocked; confirm adequate voltage from your battery (the fridge has low voltage protection and will shut off if voltage is insufficient); clean the condenser if dirty; ensure you haven't overloaded the fridge with warm items. If the fridge works on mains power but not 12V, the issue is likely with your vehicle wiring rather than the fridge itself. Check the inline fuse in the DC cable and ensure correct cable gauge for the cable length.
