The B300 Vaccine Refrigerator is specifically developed to WHO PQS specification standards and aligned to the National Department of Health requirement in 2017. This unit is designed for duty where there is risk to reliable and continuous power supply. It will hold the fridge temperature between 2˚C and 10˚C for more than 48 hours at an ambient temperature up to 32˚C. This gives clients the assurance that their vaccines will retain their efficacy and shelf life, provided electrical power is restored within the 48 hours downtime. The vaccine refrigerator also has the unique feature of having a freezer compartment for cooling water packs that are subsequently used in cooler boxes for transporting vaccines to remote locations during vaccination campaigns. The B300 Vaccine refrigerator is built to handle the robust duties expected in an African environment with a legacy of longevity in the field. The fridge comes with the Minus 40 Warranty and can be specified with a service package.
- The refrigeration system consists of two independent condensing units, one dedicated for the fridge and the other for the freezer.
- The refrigerator temperature is controlled by a 2 stage digital controller.
- The first stage of the digital controller cools the unit by switching the compressor either on or off.
- The second stage of the digital controller is set to prevent freezing of the vaccine load.
- Should internal temperature near freezing point, the controller switches on a heating unit to provide sufficient heating to prevent freezing.
- Alarm indication is provided for temperatures outside the 2˚C to 8˚C.
- There is a cavity positioned towards the back of the unit for independent temperature control
