The B200 Vaccine Refrigerator was specifically developed to WHO PQS specification standards and sponsored by the South African National Department of Health together with independent testing by the CSIR. This unit was 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 55 hours at an ambient temperature up to 32˚C. This gives clients the assurance that their vaccine will optimally retain its efficacy and shelf life, provided electrical power is restored within 48 hours. 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 B200 Vaccine refrigerator is built to handle the robust duties expected in an African environment with a legacy of longevity in the field. Early examples are still working after more than 20 years’ service. The unit 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 to the fridge and the other to 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.
