The system used for storing vaccines in good condition is called the cold chain. It is sometimes referred to as the vaccine supply chain, or the immunization supply chain. The cold chain consists of a series of links that are designed to keep vaccines within WHO recommended temperature ranges, from the point of manufacture to the point of administration.
Dulas refrigerator and freezer system has been tested in the most extreme climates, cooperate with WHO and the main non-profit organizations, passed the field test phase, independent verification, as well as laboratory tests in order to produce the product which won many awards for superior performance reliability of performance and cost-effective. Dulas was awarded in 2012 by Renewable Energy Installers Association, UK
Solar Direct Drive (SDD) is Dulas' latest innovation in solar refrigeration. this new technology uses a ground breaking phase change energy storage solution instead of traditional batteries. inspired by over three decades of solar refrigerator manufacturing and feedback from the field, this is a new generation of entirely self-powered solar refrigerators.
our development team understands well the challenging environments that vaccine refrigerators experiance. our new range incoporates our knowladge from thausands possible requirement to ensure the range is robust, easy to use and relible. all our solar powered vaccine refrigerators exceed the stringent world health organization PQS standars which mean that you can rely on their performance, quality and safety.
