Dometic NRX 50C Compressor Fridge / Freezer - 44L - 12V / 24V / 240V
$1,160
The Dometic NRX range is the current replacement path for many older Waeco and Dometic CoolMatic compressor fridges. This article is useful if you are trying to understand the model history, identify what replaced an older CR or CRX fridge, or choose a current 12V/24V compressor fridge for a caravan, camper or motorhome.
The short version is: check the old model number and cabinet size first, then compare the current NRX fridge by usable capacity, cabinet dimensions, ventilation space, power supply and door swing. Do not choose by litre capacity alone. A fridge that physically fits the cabinet and has the correct ventilation will usually be the better result.
This page covers the move from Waeco CoolMatic CR fridges through Dometic CoolMatic CRX and into the Dometic NRX compressor fridge range.
It is not a complete spare-parts interchange guide. Fridge shelves, doors, hinges, locks, trims and electronic parts can change between CR, CR-1, CRX and NRX models, even when the cabinet size looks similar. If you are buying parts for an older fridge, use the exact model label inside the fridge before ordering.
If you are choosing a new caravan fridge more generally, see our caravan fridge buying guide. If you are troubleshooting an existing Dometic fridge, start with Dometic fridge troubleshooting.
Waeco was founded in West Germany in 1974 and became well known for mobile cooling. Dometic acquired Waeco in 2007 and later folded the Waeco name into the Dometic range. The CoolMatic name stayed around for some time because many Australian caravan owners already knew it.
The original Waeco CoolMatic CR series was a 12V/24V DC compressor-fridge range, with common model sizes such as CR-50, CR-65, CR-80, CR-110 and CR-140.
Dometic later introduced models with 240V AC capability as well. This created some easy-to-miss naming differences. For example, the CR-110 became the CR-1110 in the later range. Some parts from the older CR-110, including shelves, doors and fridge locks, were not automatically compatible with the newer CR-1110 style. These are often informally called the CR-1 range.
The CoolMatic CRX series followed after that, with sizes such as CRX-50, CRX-65, CRX-80, CRX-110 and CRX-140. The CRX range kept the broad compressor-fridge concept, but updated the styling and features.
The Dometic NRX range is the next step in that line. It is the current family to look at when replacing many older CoolMatic-style compressor fridges, provided the cabinet dimensions and installation requirements match.
Start with the fridge cavity, not the brochure. Measure the cabinet opening, depth, ventilation space and door-swing clearance. Then compare those measurements against the current fridge dimensions on the product page.
The current NRX C-series models in this article are:
| Model | Nominal capacity | Power | Typical use |
|---|---|---|---|
| NRX 50C | 44 litre | 12/24V DC and 240V AC | Small campers, compact van builds and tight cabinets. |
| NRX 60C | 55 litre | 12/24V DC and 240V AC | Small to mid-size layouts needing a little more storage than the 50C. |
| NRX 80C | 75 litre | 12/24V DC and 240V AC | Common caravan and campervan size where cabinet space allows. |
| NRX 115C | 113 litre | 12/24V DC and 240V AC | Larger caravan fridge replacement where extra food storage is needed. |
| NRX 130C | 126 litre | 12/24V DC and 240V AC | Larger vans and motorhomes with enough cabinet depth and ventilation. |
When replacing a CR, CR-1 or CRX fridge, do not assume the number alone makes it a direct swap. Confirm the cabinet size, mounting method, ventilation path, power wiring, door hinge position and whether any trim or frame parts are needed.
The NRX range is still a compressor-fridge range, but it moved the design forward in several practical ways:
Dometic lists improved energy efficiency compared with comparable older designs, but real-world power use still depends on ventilation, ambient temperature, thermostat setting, how often the door is opened and how warm the food is when loaded.
Before ordering a replacement compressor fridge, check:
Compressor fridges are sensitive to poor ventilation and voltage drop. If a new fridge is fitted into a tight cabinet with poor airflow, it may run longer and use more power. If the 12V wiring is too light or the battery voltage is low, the fridge may cut out or behave like it has a fault.
The current C-series NRX models discussed above are shown below. Use these as the buying path after you have checked the old model label and cabinet measurements.
For broader fridge selection, compare compressor fridges against absorption fridges and drawer fridges before committing to cabinet work. The right answer changes with how you camp, your battery/solar setup, how much 240V access you have, and whether the fridge cavity is already built.
