Dometic RMDX Spare Parts

The Dometic RMDX Series, including the popular RMDX21 and RMDX25, represents Dometic's premium range of tropicalised 3-way absorption refrigerators designed specifically for caravans, motorhomes and RVs operating in demanding conditions.

Engineered for reliable performance in harsh Australian climates, the RMDX range features upgraded cooling technology designed to maintain cooling efficiency in high ambient temperatures where standard absorption refrigerators may struggle. Operating on LPG gas, 12V DC and 240V AC power, these refrigerators provide completely silent cooling without compressor noise or vibration.

Although the RMDX Series has now been superseded by newer Dometic models, it remains highly regarded amongst travellers seeking dependable off-grid refrigeration and strong hot-weather performance.
