Solar Direct Drive Series

A pioneer in solar-direct-drive (battery-free) technology, SunDanzer has installed thousands of SDD vaccine refrigerators worldwide since introducing its first SDD model in 2011. The SDD design eliminates the need for batteries by utilizing thermal storage built into the walls of the unit. The refrigerator connects directly to the solar array mounted on the roof of the health clinic.

SunDanzer currently offers two models of SDD vaccine refrigerators, both of which are listed on the W.H.O. PQS listing.
