Cold-chain vehicles are going electric, and their refrigeration units must follow. NEWBASE’s DC Refrigeration Unit Series is a family of all-direct-current inverter cooling units developed specifically for new energy refrigerated vehicles, drawing power directly from the vehicle battery across a DC voltage range of 12V to 96V — no belt drive, no fuel-burning sub-engine, and zero tailpipe emission during cooling.

Six Advantages of the DC Cooler
The series is built around six engineering characteristics taken directly from NEWBASE’s product documentation:
- DC rotor compressor with anti-turbulence and tilt tolerance for real road conditions;
- temperature range reaching -5°C for refrigerated and -20°C for frozen cargo;
- high-efficiency air-cooled evaporator for fast cabinet pull-down;
- energy saving and emission reduction — no pollution, zero emission, low running cost;
- small size, light weight and clean appearance that preserve vehicle payload;
- DC voltage 12V to 96V, a frequency-conversion refrigeration unit dedicated to new energy refrigerated vehicles.
Because the compressor is fully electric and speed-controlled, cooling output follows the actual cabinet load instead of engine RPM. For fleet operators this translates into stable box temperatures during stop-and-go urban delivery, quieter operation in residential zones, and no idle-fuel penalty when doors open frequently.

Model Range at a Glance
| Model | Voltage | Power | Cooling Capacity | Box Volume (m³) |
|---|---|---|---|---|
| Z058-J48 | 48V/60V | 320W | 620W | Refrigerated 0.5–1.5 / Frozen 0.5 |
| D150-J48 | 48V/60V | 640W | 1,085W | Refrigerated 2–5 / Frozen 0.5–2 |
| D178-J48 | 48V/60V | 820W | Refrigerated 1,950W / Frozen 1,100W | Refrigerated 4–6 / Frozen 3–4 |
| D298-J60 | 48V/60V | 1,400W | Refrigerated 3,400W / Frozen 1,850W | Refrigerated 7–12 / Frozen 5–7 |
The range steps from the compact Z058-J48 for micro deliveries to the D298-J60, which keeps bodies of up to 12 cubic metres in refrigerated mode (5–7 cubic metres frozen) at temperature. Every model runs on the 48V/60V platform common to electric refrigerated tricycles and light commercial vehicles, which is why the same DC units also power NEWBASE’s refrigerated tricycle series.

Built for the Last-Mile Cold Chain
Urban grocery, pharmaceutical and fresh-food distribution increasingly happens on electric three-wheelers and light vans with limited battery capacity. A 320W-to-1,400W electric cooling demand that scales with load — rather than a fixed-speed compressor — lets operators plan energy budgets the same way they plan driving range. Combined with the tilt-tolerant rotor compressor, the series addresses the two constraints that define last-mile cold chain: limited power and constant movement.
