The Dometic RUC Series represents Dometic's premium range of 12V/24V compressor refrigerators designed specifically for caravans, motorhomes, campervans and marine applications. Built around a slim 550mm-wide cabinet, the RUC range offers exceptional cooling performance while maintaining a footprint that can often pass through a standard caravan entry door during retrofit installations.
Unlike Dometic's RUA absorption refrigerators, the RUC Series uses advanced compressor cooling technology, delivering fast cool-down times, reliable freezer performance and consistent operation regardless of vehicle angle or terrain. Operating from 12V DC, 24V DC and 240V AC, these refrigerators are ideal for travellers relying on lithium batteries, solar systems and modern off-grid electrical setups.
Designed to perform in Australia's harsh conditions, the RUC range carries a Tropical Climate Rating (Class T) and is engineered to operate effectively in ambient temperatures up to 43°C.

- Improved energy efficiency when paired with lithium battery systems
- Consistent cooling in extreme temperatures
