What is Reefer Truck (Refrigerated Transport)?
A Reefer Truck is a temperature-controlled commercial vehicle equipped with an active mechanical refrigeration unit and high-density thermal insulation. It maintains precise internal temperatures ranging from -20°C to +8°C throughout transit, engineered specifically for perishable goods, fresh dairy, frozen foods, and temperature-sensitive biopharmaceuticals.
Reefer Truck Technology and Temperature Control
Reefer containers are constructed with polyurethane foam (PUF) insulation panels and heavy-duty refrigeration compressors powered by direct-engine drive or auxiliary diesel generator units. Advanced digital microprocessors maintain programmable setpoints to ensure zero thermal deviation during highway transit.
- Deep Frozen (-20°C to -18°C): Ice cream, frozen seafood, meat, and biological cultures
- Chilled (+2°C to +8°C): Vaccines, insulin, fresh dairy, poultry, and biotechnology drugs
- Controlled Ambient (+15°C to +25°C): Confectionery, chocolates, and specialized pharmaceuticals
IoT Telemetry and Continuous Temperature Logging
Modern cold-chain compliance mandates real-time thermal audits. VRC Mobility reefer trucks feature continuous IoT temperature and door-sensor telemetry that logs cabin temperatures every 60 seconds. Shippers receive automated SMS/WhatsApp alerts if temperatures deviate by more than ±1.5°C from the target setpoint.
Frequently Asked Questions
What is the temperature range of a VRC cold-chain reefer?
VRC Mobility reefer trucks operate across a temperature spectrum from -20°C deep freeze up to +8°C chilled, suitable for pharma vaccines, dairy, fruits, and frozen foods.
How is cold-chain compliance audited during delivery?
Upon arrival at the destination dock, a complete digital temperature log graph is generated and timestamped alongside the digital Proof of Delivery (POD) before cargo unloading begins.
