COLD CHAIN IN ONE BOX

The THERO Model transforms temperature-sensitive shipments into self-contained, power-free cold-chain units. Each box incorporates long-duration thermal protection to help maintain the required internal temperature range throughout transit—without continuous refrigerated transportation or repeated transfers into cold storage.
By enabling temperature-sensitive goods to move through conventional freight networks much like general cargo, THERO gives shippers greater flexibility in selecting cargo space, planning routes, and combining transport modes. Whether shipments pass through extreme climate conditions—from +35°C to −30°C ambient temperatures—THERO helps protect product integrity and maintain temperature stability throughout the journey, subject to the validated configuration and applicable operating conditions.
