Hybrid Solar Power Pack for Walk In CoolerA Green Initiative........NCCRC,being largely instrumental in the area of integrating the newer technologies in the cold chain & continually putting its efforts towards making the immunization cold chain more & more reliable. As striving for excellen...

EHC is a valuable method of obtaining excess energy from an SDD refrigerator, however an autonomous solar direct system powering USB ports is a simpler, more reliable and less expensive method of providing auxiliary power. USB ports can be powered directly from a solar panel, no batteries are requi...

Dear TechNet-21 community, Further to the publication of the English and French versions of the Decommissioning and safe disposal of cold chain equipment guidance earlier this year (available here https://bit.ly/2xTLDYa), we are glad to share with you that the Arabic and Russian versions of the doc...

To ensure that solar direct drive (SDD) appliances can keep vaccines at acceptable temperatures continuously, the installed photovoltaic array often produces excess power that is not used by the primary cooling load and this excess power generally goes unutilized. If this power is to be used, the p...

WHO and UNICEF have just published a new evidence brief on solar direct-drive (SDD) vaccine refrigerators and freezers. It includes case studies from Tanzania, Colombia and Kenya, as well as an overview of SDD technology and how to make sure that SDD technology is the right choice. Here's the link: ...

I’ve been reading with great interest the most recent issue of Vaccine, which is dedicated to “Building Next-Generation Immunization Supply Chains”. http://www.sciencedirect.com/science/journal/0264410X/35/17 I particularly enjoyed the following article but was surprised to read that the authors i...

Dear I like to share with you in this space a video about the instalation, basic maintenance and operation of one of the solar equipments with PQS that are installed in my country (Colombia), nowadays we have 300 equipments in operation. Best regards ...

Among the TECHNET postings on cold-chain equipment there are embedded remarks pointing towards the need to make vaccine refrigeration simpler and less expensive to procure, more responsive to energy changes and easier to use and maintain. For example, to choose a refrigerator now current WHO, UNICEF...

In case this new article published in Applied Energy is of interest http://www.sciencedirect.com/science/article/pii/S0306261916302793 AbstractAn intermittent solar adsorption refrigerator can supply cold needed in third world countries, especially for vaccine and medicine preservation. This paper...

Interesting paper on system design in Nigeria from Health Affairs. Abstract One of the major problems facing Nigeria’s vaccine supply chain is the lack of adequate vaccine storage facilities. Despite the introduction of solar-powered refrigerators and the use of new tools to monitor supply levels,...

I was recently looking at the “System Sizing tool 3/3” in a 2DI3 “Technical evaluation and Methodology” a unicef publication. The publication originated from a 2DI3 SDD industry meeting. The sizing method prescribed is based on the premise that “the daily potential solar energy supply is calculated...

WHO and UNICEF have just released a new joint publication on solar fridges and freezers that is intended to provide managers in national immunization programmes with guidance on how to implement successful solar-powered vaccine refrigerator and freezer systems. It takes into account new developments...

Reposted from JSI's The Pump Jeff Sanderson,Senior Technical Advisor African immunization supply chains need to be transformed. Between 2010 and 2020, new vaccine introductions will quadruple the volume of vaccines per immunized child. The number of vaccine doses that health workers will adminis...

Choices, choices, choices – they are both the bane and blessing of our times. As immunization managers, we now have a wide array of PQS-prequalified cold chain equipment to choose from, but how do we make the right choices and get the best value for our bucks? The TechNet Product Reviews area helps ...

Sun Frost developed a hybrid refrigerator/ice pack freezer, the FRH-3. The Sun Frost FRH-3 has a SDD freezer and a battery powered refrigerator. The SDD freezer is the same size as our F-1 (http://www.sunfrost.com/batteryless_direct_drive_freezer.html) and incorporates the same technology which allo...

Success has many fathers, failure is an orphan. Yet, we can learn so much more from failure than successes. The amazing safety of modern flight is a result of this systems-based analysis of failures. In contrast, medical safety continues poorly with a culture of 'blame' focusing on individuals rat...
