Please refer the Video developed by NCCRC with support of UNICEF with the objective of making the task of WIC/WIF installation much easier, though demonstration of interconnections between WICs/WIFs & associated equipment/control units. The efforts are towards briefing the purpose & illustr...

Cher-e-s membres francophones de la communauté TechNet-21, C'est avec grand plaisir que je partage avec vous les nouvelles directives de l'UNICEF pour la gestion des données issues de l’inventaire des équipements de la chaîne du froid, en français.  Ce document offre des orientations sur les ...

Chers tous, Avec le soutien de Gavi, PATH et Village Reach ont récemment publié une nouvelle ressource pour la gestion de l'inventaire des équipements de la chaîne du froid (IECF), désormais en français :"Recommandations  pour l'inventaire des équipements de la chaîne du froid : Améliorer...

Dear all,  With the support of Gavi, PATH and Village Reach have recently published a new resource for cold chain equipment inventory (CCEI) management. "Cold chain equipment inventory guidelines: Improving the quality and accuracy of national cold chain equipment inventory data"  - is a...

Dear friends, Greetings from National Cold Chain Resource Centre,India!!!!!!! Would like to introduce NCCRC in brief. It is joint initiative of GoMH, MoHFW - GoI & UNICEF and with its technical mandate in support of immunization programme,largely instrumental in developing skills of Cold ...

National Cold Chain Resource Centre (NCCRC) India,a Joint Initiative of Goverment of India,UNICEF-India Country Office & Goverment of Maharashtra. The primary mandate for the centre is.. Capacity building activities of Cold Chain EquipmentRepair, Maintenance and Management, Formulating tech...

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...

One of the beneficial features of SDD refrigerators is its relative simplicity. Electrically two wires from the solar array are directly connected to the compressor. This simplicity minimizes problems in the field and simplifies repairs. Energy harvesting technology introduces a great deal of electr...

Dear TechNet community members, Warm greetings! The cold chain situation in many countries is sub-optimal and affects the capacity of national immunization programs to deliver potent vaccines to all women and children.To help improve this situation, the Gavi Board approved the Cold Chain Equipment ...

Dear colleagues, I am looking for a template of cold chain equipment repair & maintenance record, a template of CCE spare parts record etc which can be used as specimen in training materials on CCE repair and maintenance in the immunization programme. Links, reference documents etc will be highly a...

We are working with ILRs. While daily operations, it was found that there is formation of water droplets inside the device. We want to measure the amount of condensation taking place inside the device in a day. We also tried to calculate the Dew Point Temperature but not much useful. Kindly sugge...

Thanks to the flexibility of the TechNet-21 website, I can share two older (circa 1985) collections of densely technical and highly practical equipment maintenance documents developed by WHO using the TechNet Resource Library (TRL). Once only available in hardcopy or in a digital corner of the onlin...

A new policy paper on the vaccine supply chain, "System Design: Repair or Replace," has recently been released. It's attached and can also be found here: http://villagereach.org/vrsite/wp-content/uploads/2009/08/villagereach-system-design_repair-or-replace.pdf. This paper considers the broader conce...

Dear All, I am a project coordinator for Nexleaf Analytics. We are a nonprofit organization dedicated to building low-cost technologies that create positive health, environmental and social impact. I have attached a Standard Operating Procedure (SOP) for fridge maintenance for your review. Additio...

We think of fridge holdover time (autonomy) in the context of power shortage, whether cloudy weather in the case of solar, or power cuts for A/C systems. While this will see functioning equipment through power shortages and keep vaccine 'safe' for a given duration (a parameter which varies immensel...

In solar powered vaccine storage systems high quality wet cell batteries have the potential of lasting longer than sealed batteries. However, they periodically need the addition of distilled water. Distilled water can be hard to obtain in remote areas. Sun Frost has developed a method using waste h...

Compressor Replacement Without a Vacuum Pump Replacement of a compressor requires the use of a vacuum pump. Solar powered vaccine refrigerators are generally located away from the utility grid. Most vacuum pumps are powered by AC grid power making compressor replacement difficult. We have develo...

What service life do you think vaccine refrigerators should be able to provide? For example, some products may suggest a 10 year life while others suggest longer, with typical repairs. PQS requires a 2 year warranty for a vaccine fridge. Solar powered vaccine fridge systems require solar electric mo...
