Refrigerated Truck Unit

1. Application and Vehicle Compatibility

The NEWBASE NBESR-1000A pure electric integrated refrigeration unit is specifically engineered for new-energy light-duty refrigerated trucks with body lengths ranging from 7.5 to 8.5 meters. It is fully compatible with a variety of zero- or low-emission powertrain platforms, including battery electric vehicles (BEVs), hydrogen fuel cell electric vehicles (FCEVs), methanol-powered systems, and range-extended electric vehicles (REEVs). This versatility makes it an ideal solution for urban cold-chain logistics, pharmaceutical transport, and last-mile delivery applications where sustainability, noise reduction, and regulatory compliance are critical.

2. Refrigeration Capacity and Temperature Performance

Designed for insulated cargo compartments with a volume of 42 to 46 cubic meters, the NBESR-1000A delivers robust cooling performance capable of maintaining temperatures as low as –18°C to –20°C, meeting international standards for frozen food and medical cold-chain transport (e.g., ATP Class F). The unit employs a high-efficiency, hermetic scroll compressor integrated directly within the condenser assembly, enabling rapid pull-down times and stable temperature control even under frequent door-opening conditions.

3. Integrated Design and Energy Efficiency

The NBESR-1000A features a fully integrated structural design, where the condenser and evaporator are combined into a single compact module. This not only reduces installation complexity and space requirements but also minimizes refrigerant piping losses. Coupled with variable frequency drive (VFD) technology, the system dynamically adjusts compressor and fan speeds based on real-time thermal load, significantly lowering energy consumption—typically by 20–30% compared to fixed-speed alternatives—while extending component lifespan.

4. Smart Connectivity and Remote Management

Equipped with a built-in 4G communication module, the unit supports advanced telematics functions such as:

• Real-time temperature monitoring
• Remote diagnostics and firmware updates
• Proactive after-sales service alerts (e.g., filter maintenance, refrigerant leakage warnings)
• Over-the-air (OTA) parameter adjustments for setpoint temperature or defrost cycles
  This IoT-enabled architecture enhances fleet operational efficiency and ensures continuous compliance with cold-chain integrity requirements (e.g., GDP for pharmaceuticals).

5. Standby Power and Auxiliary Heating Function

To preserve vehicle battery life during stationary operations (e.g., loading/unloading or overnight parking), the NBESR-1000A includes an AC 380V shore power input. When connected to external grid power, the refrigeration system operates independently without drawing energy from the truck’s traction battery—a key feature for maximizing vehicle range and reducing total cost of ownership.

Additionally, the unit incorporates an electric heating function capable of raising compartment temperatures to +6°C to +15°C, which is essential for transporting temperature-sensitive goods like fresh produce, flowers, or certain biologics that require above-freezing conditions.
