Can the Dry Ice Pellets Used for Transporting Temperature-Sensitive Vaccines?

The global distribution of temperature-sensitive pharmaceuticals, particularly mRNA vaccines and biological samples, strictly requires an unbroken cold chain capable of maintaining temperatures between -70°C and -80°C. Standard gel packs or mechanical refrigeration simply cannot achieve these extreme cryogenic conditions. The dry ice pellets produced by our SL series machines are not just suitable; they are the absolute industry standard for this critical task.

Hospitals, pharmaceutical distribution hubs, and medical research facilities often rely on external gas suppliers for their dry ice. However, in the medical field, a delayed delivery or receiving degraded, sublimated dry ice can result in millions of dollars of ruined vaccines. By installing an on-site dry ice pelletizer like the SL-50 or SL-100, medical logistics centers eliminate supply chain vulnerabilities. You can instantly produce fresh, pure dry ice at a stable -78.5°C exactly when the insulated shipping containers are being prepared for dispatch.

Furthermore, the physical properties of the pellets play a vital role. Using our interchangeable dies, operators can produce 10mm or 16mm pellets. These spherical, high-density (1550 kg/m³) pellets can be effortlessly poured into the EPS (Expanded Polystyrene) dry ice shipping containers, tightly filling all the microscopic voids around the fragile vaccine vials. This creates an impenetrable, long-lasting thermal barrier that protects the life-saving medical cargo for days during cross-border transit, ensuring total compliance with stringent WHO (World Health Organization) cold chain guidelines.
