Arktek Passive Vaccine Storage Device
Intellectual Ventures Lab - Global Good Program
The Arktek Passive Vaccine Storage Device is a vaccine storage device that can store up to 5 L of vaccines for over 35 days without the need of an external power supply.
The Arktek PSD, a passive storage device, is designed to keep vaccines at appropriate temperatures for a month or more with repeat vaccine retrievals and no need for electricity. It is easily implemented with no need for capitol improvements and has no complex parts to maintain or install. Using a single load of ice blocks for thermal energy storage, the Arktek PSD maintains EPI standard temperatures (0~10°C) for up to 5 liters of vaccines for a minimum 35 days in 43°C day time ambient temperatures. With monthly supplied ice blocks, the Arktek PSD can support vaccination services for a community of approximately 6,000 people. The Arktek PSD is helping to extend vaccination services in remote health posts lacking reliable grid power. This ruggedized vaccine carrier can store up to 300 vaccine doses for over a month. The carrier uses vacuum-insulated technology that allows repeat retrievals and includes a monitor that tracks location using GPS, internal temperature, and the number of retrievals, then transmits this information through USB connection or over SMS messaging.
The Arktek PSD is designed for communities of up to 6,000 people in remote regions of the world lacking grid power especially in GAVI countries. It is currently in use in Ethiopia, Senegal, Nigeria, Nepal, Fiji, Haiti, Pakistan, Ghana, Liberia, Mozambique, and Sierra Leone.
Global Good (collaboration between Intellectual Ventures and Bill & Melinda Gates Foundation), AUCMA is moving Arktek into distribution in the communities with the lowest rates of vaccination.

Solar Fridge. An economic evaluation of these devices in various settings can be found in Vaccine.
Goal 3: Good health and well-being
Health care practitioners in rural regions and aid workers on vaccination campaigns, etc. especially in GAVI countries.
Manufacturing is in progress with AUCMA, a Chinese refrigeration company
Distributed to healthcare workers directly through large-scale projects with agencies such as WHO. The product may also be purchased from Via Global Health.
As of 2017, over 500 devices have been distributed.
The time in hours without (solar) energy input during which all points in the vaccine compartment remain between +2°C and +10°C without (solar) energy input and at the maximum ambient temperature of the temperature zone for which the appliance is rated.
Using a single load of ice blocks for thermal energy storage, the Arktek PSD maintains EPI standard temperatures for up to 5 liters of vaccines for a minimum 35 days in 43°C day time ambient temperatures. Contains 8.6 liters of water ice. Arktek’s tested thermal heat leak is an average of 1 Watt per day with a day/night cycle of 43°/25°C.
The two ice blocks are first stacked against the inner walls and then the vaccine carrier cups are placed in the middle. The device is equipped with temperature sensors that will alert the user if the temperatures inside reach an unsafe range.
The product dimensions are 52.8 x 74.7 cm. The product weight when empty is 22 kg and when full is 39.5 kg. More information can be found in the product manual.
The manufacturer, AUCMA, will provide parts in case of any repair needs. Interview with designer, July 2015
The economic analysis of this device considers initial cost, as well as cost over 10 years, the estimated lifetime of the device.
Stores up to 300 doses
Requires no electricity, holds vaccines at safe temperature for for 30 to 60 days, depending on outside temperatures and humidity with repeat vaccine retrievals, transportable, low-maintenance.
Field testing was performed in Senegal and in Ethiopia in 2014. The testing in Senegal showed that the device meets the WHO temperature standards for vaccine storage with no need for an external power source, internal temperatures were successfully maintained for 35 days in all use cases, the device fit well within the current vaccine logistic systems, and received positive user feedback. The testing in Ethiopia showed that again the device was able to maintain a safe internal temperature range for 35 days in different use cases and it received positive user feedback.
The device is designed to only store vaccines, some parts may be flammable (nylon ropes), keep device away from acid, alkali, and other corrosive substances, only authorized personnel may perform maintenance on the device. For further safety considerations, refer to the user manual.
A single-use battery to supply power to the sensors must be installed.
