Solar powered vaccine refrigerator
Dulas has announced the launch of its VC60 Solar Direct Drive (SDD) combined vaccine refrigerator and icepack freezer. The World Health Organisation (WHO) accredited VC60 SDD is part of the Dulas Solar Direct Drive product range that features Freeze-Free technology, ensuring that vaccines stored in the refrigerator are never exposed to harmful freezing temperatures. The new model features advanced technology including an icepack freezer with additional storage and an integrated Solar Socket - a solar harvesting device to support vaccine outreach work in remote areas. The Hot Zone rated design of the VC60 SDD provides an extended operating temperature range of +5 °C to +43 °C that enables it to successfully function regardless of extreme variations in temperature. Dulas' solar-powered refrigerator/freezer also features an integrated Solar Socket for charging mobile phones and other electronic devices. The VC60 SDD features a larger storage capacity and advanced autonomy and holdover rates (i.e., the length of time that it can maintain temperature range with or without solar radiation, respectively) of 94 hours and 11 minutes. The technology is designed to work around the clock, using sophisticated computer modelling that carefully matches the energy from the solar photovoltaic modules to the needs of the refrigerators. Dulas' FreezeFree technology is designed using a combination of advanced solar and temperature control systems, together with phase change materials to ensure that vaccines are kept at the recommended temperature range of +2 °C to +8 °C.
