The Demax DM series (models: DM90/138/188/238/318) is a line of DC 12V/24V freezers (90L–318L capacities) tailored for solar/battery power scenarios.
Equipped with fully hermetic Wanco/SECOP compressors, 60mm CFC-free PU insulation, and R134A refrigerant, these units cool to -18°C (at 30°C ambient) with high-temperature resistance and energy-saving design. They connect directly to DC sources (e.g., solar) or AC via optional adapters, plus low-voltage auto-shutdown for protection.
Features include single top doors with locks, CE/ROHS certification, and compact-to-mid-sized builds (535–1260mm L). Ideal for off-grid/rural areas, small businesses, or flexible-power storage needs, the series balances efficiency, durability, and versatile compatibility across capacity options.
