VC150SDD Solar Direct Drive Refrigerator & Freezer

The VC150SDD is a Solar Direct Drive combined vaccine refrigerator and water pack freezer. With a vaccine storage capacity of 102 litres and a 43L freezer, it is the perfect solution for larger health facilities conducting outreach programmes. The VC150SDD has been independently verified to deliver 4 x 0.6L fully frozen water packs each day (2.4kg of ice), even at +43C ambient, making it easier to plan outreach activities.

Like all our SDD refrigerators the VC150SDD utilises our optimised solar technology to offer the perfect balance of array size and autonomy, delivering exceptional reliability whatever the weather.
Fully GAVI CCEOP compliant with the highest level of Grade A Freeze Protection and a +5C to +43C extended temperature operating range.
