Temperature-sensitive deliveries, whether fresh groceries, ready-to-eat meals, or pharmaceuticals, have traditionally depended on synchronous handoffs and manual coordination, leaving the cold chain vulnerable to breaks, spoilage, and compliance risk. Columat's Temperature-Controlled Smart Lockers solve this by turning the pickup and drop-off point itself into a connected, climate-managed exchange system.

Each locker is built on a modular hardware architecture with independent cooling modules that can be configured as chilled (2–8 °C) or frozen compartments within the same unit, and the enclosure is antibacterial-certified for food- and pharma-grade hygiene. Embedded software continuously tracks temperature, door events, and system status, triggering immediate alerts if a deviation or exception occurs, while every access and environmental reading is logged to support audits and regulatory compliance.

Users interact with the locker through a touchscreen interface, QR or barcode scanning, or RFID/NFC credentials, with connectivity available via SIM, Wi-Fi, or local network, and the system integrates seamlessly with existing operational platforms and workflows. Dimensions, materials, and compartment layouts are fully customizable to fit grocery and supermarket pickup points, unattended food service, hospital pharmacy dispensing, or carrier and courier networks handling cold chain deliveries.

Deployed use cases report up to 100% traceability and sanitary compliance, an 87% reduction in failed deliveries and incidents, a 63% drop in physical or operational intervention, and 33% faster logistics delivery times — enabling secure, 24/7 autonomous cold chain operations without dependency on staff or opening hours.
