Parcel Lockers

Thermal Management

Sonoran Desert surface temps exceed 160°F on exposed metal — accelerating mechanical failure and degrading lock mechanisms. Our passive radiative cooling technology reduces mailbox surface temperatures by up to 40°F without electrical infrastructure, applied during new installation or as a standalone retrofit.
