Features

Temperature-Controlled Environment

Equipped with a refrigeration unit (mechanical or cryogenic), it maintains precise temperatures ranging from -30°C to +30°C, ensuring perishable goods (e.g., food, pharmaceuticals) stay fresh during transport.
Insulated Construction

Walls, floor, and roof are built with polyurethane foam insulation (50–150 mm thick) to minimize heat exchange, achieving high thermal efficiency (K-value ≤0.4 W/m²·K).
Durable & Airtight Design

Seamless stainless steel or aluminum inner lining prevents bacterial growth, while airtight doors and seals block external humidity and contaminants.
Advanced Monitoring Systems

Real-time temperature tracking, GPS location, and remote alerts via IoT-enabled sensors ensure compliance with cold chain logistics standards (e.g., HACCP, GDP).
