Blog circa Thermo Carrier Launches Ultralow Temp PCM for Cold Chain Logistics

In temperature-sensitive logistics, particularly for goods requiring strict frozen environments between -15°C and -25°C, maintaining consistent thermal conditions remains a critical challenge. Traditional cold chain solutions often struggle with limited endurance, environmental fluctuations, and operational complexity, failing to meet growing demands for precise temperature control.

Core Temperature Control Mechanism: Phase Change Material (PCM) Energy Regulation

The Thermo Carrier transport system utilizes advanced phase change material (PCM) technology to achieve thermal stability for over 120 hours while complying with ISTA 7D standards. PCM substances absorb or release significant latent heat within specific temperature ranges.

When external temperatures rise above the PCM's melting point, the material absorbs heat through melting, preventing internal temperature increases. Conversely, when ambient temperatures drop below the PCM's freezing point, it releases stored heat through crystallization, compensating for thermal loss.

This dynamic phase transition process serves as an automatic temperature regulator. During transport, despite frequent door openings or extreme environmental variations, the PCM continuously adjusts energy exchange to maintain the required -15°C to -25°C range. Rigorous experimental validation supports this mechanism's effectiveness.

Technical Advantages and Operational Benefits

Compared to conventional dry ice or electric refrigeration systems, the PCM technology demonstrates superior performance:

• Extended temperature stability: Optimized PCM formulations enable 120+ hours of thermal control, exceeding most single-use cold chain packaging capabilities for long-haul or multi-stop shipments.
• Environmental adaptability: The phase transition process operates without external power, suitable for air, ground, and maritime transport.
• Operational efficiency: The reusable system reduces long-term costs with simplified procedures—only requiring PCM pre-cooling without complex charging steps.
• Precision compliance: The design meets stringent ISTA 7D testing standards, ensuring reliable performance under simulated harsh transport conditions.

This PCM-based solution provides pharmaceutical, biological, and premium food industries with reliable frozen transport capabilities, significantly reducing product degradation risks while ensuring quality and safety standards.
