Leading British solar refrigeration manufacturer and renewable energy specialist, Dulas is in the process of delivering over 300 of its VC150SDD solar refrigerators to Nigeria. These World Health Organization (WHO) accredited refrigerators will be used to safely store vaccines in Yobe, Bauchi, and Kaduna states, Alternative Energy Africa reports.
With the WHO aiming to achieve 90% immunization coverage in each of its target countries by 2020, reliable storage of vaccines at the correct temperature is of crucial importance. Although the WHO believe that they will soon be able to rid Nigeria of polio, immunization programs can often be hindered by storage issues. This is most often the case in more remote areas with only sporadic access to the national grid. In the absence of a reliable source of electricity, temperature-sensitive vaccines will spoil and go to waste.
The Dulas solar-powered refrigerators use an advanced non-corrosive phase change material for the energy store, which cannot be damaged by over-charging or discharging, thereby ensuring there is no need to replace it. Combined with Dulas’ intelligent variable speed controller, this extends the usability of SDD fridges and makes them more resilient in low-sun conditions.
