Multi-Zone Refrigerated Trailer Split-Bulkhead Temperature Management
Optimize multi-temperature fleet operations: manage dual and triple compartment split-bulkheads, balance remote evaporator airflow, and prevent thermal bleed between ice cream (-20°F), fresh produce (+34°F), and ambient freight.
Remote Evaporator Balancing
Multi-temp architectures (Thermo King Multi-Temp Spectrum, Carrier Vector 1950 MT) distribute high-efficiency suction and liquid lines to secondary ceiling evaporators with precision PWM expansion valves.
Movable Thermal Bulkheads
Composite lightweight insulated partition panels with heavy-duty perimeter compression seals prevent cold air bypass. Bulkheads can be positioned transversely or split longitudinally for grocery distribution.
Multi-Zone Dispatch Intelligence
EXSPEEDITE TMS models cargo compartments on a single Bill of Lading, tracking independent setpoints, continuous sensor telemetry, and door opening histories across multi-stop grocery delivery routes.

Multi-Temp Food Distribution Configuration Guide
| Compartment Split | Primary Nose Zone | Secondary Zone | Air Distribution Strategy | Operational Risk Factor |
|---|---|---|---|---|
| Frozen / Produce Split | -15°F to -20°F (Host Unit) | +34°F to +38°F (Remote Evap) | Over-bulkhead flexible supply chute | Freezing damage on produce adjacent to partition wall |
| Frozen / Dry Ambient Split | 0°F to -10°F (Host Unit) | Ambient (Passive / Fan assist) | Return air bulkhead baffle plate | Moisture condensation & frost buildup on bulkhead skin |
| Triple Zone (Frozen / Fresh / Dry) | -20°F (Front Nose) | +36°F (Center Zone) • Ambient (Tail) | Dual remote ceiling evaporators | Door opening thermal recovery at high-frequency stops |
