Dometic RUA5208X | RUA6408X | RUA6508X | RUA8408X | RUA8508X

The Dometic RUA Series represents Dometic's latest generation of premium 3-way absorption refrigerators, purpose-built for modern caravans and motorhomes. Designed around a slim 550mm-wide cabinet, the RUA range provides a practical solution for replacement fridge installations where access through caravan doors can be challenging.

Operating on LP Gas, 12V DC and 230–240V AC, the RUA Series delivers completely silent cooling using Dometic's proven absorption technology. With improved electronics, modern styling and advanced energy management, the RUA range has become one of the most popular upgrades for owners replacing older Dometic refrigerators.

The range includes both single-door and double-door models, with capacities ranging from approximately 153 litres to 224 litres.

About the Dometic RUA Series

The RUA Series was developed as the successor to several earlier Dometic absorption refrigerator platforms, including selected RM, RML and RMD Series models.

A key advantage of the RUA platform is its slim-width cabinet design, allowing many units to be installed without removing caravan windows or requiring extensive cabinet modifications.

Key Features

Universal Energy Selection (UES)

The RUA range features Dometic's advanced Universal Energy Selection (UES) control system with a modern TFT display.

The refrigerator can automatically select and prioritise:

1. 230–240V AC mains power
2. 12V DC while travelling
3. LP Gas when camping off-grid

Users can also manually select their preferred operating mode when required.
