Power Requirements

Nominal 12 Vdc solar electric array. Recommend 2-12V 120W panels, one facing east, one facing west.

Vaccine storage capacity (Liters)

Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

SunDazer’s BFRV55 vaccine refrigerator uses phase change material (PCM) to maintain an inner temperature between 2 and 8°C. The refrigerator uses the solar energy to “freeze” this phase change material and then uses the cooling from this material to keep the vaccine compartment cold during the night and on cloudy days.

SunDanzer’s BFRV55 refrigerators employ User Independent Freeze Protection, meaning freeze protection capabilities are independent of healthcare workers use and operation of the refrigerator. The vaccines can be stored anywhere in the fridge (even in contact with the walls). No defrosting is required and the thermostat function/setting does not affect the freeze protection.

SunDanzer’s refrigerators make use of the ‘East-West’ array provides, which they suggest on average delivers at least 3 more hours of compressor run time than a traditional South facing array. This configuration allows a fully illuminated panel to start the compressor early in the morning and late in the afternoon. The East-West array also allows the compressor to have more chances to run.

BFRV55 specifications:
Dimensions: 96.2 cm x 71.1 cm x 86.8 cm;
Weight: 99 kg (2);
Gross vaccine storage capacity: 55 Litres
Cabinet insulation is 110mm high density polyurethane.
Refrigerant is CFC-free R134A. (3)

Rated for Hot climate zone of 43°C. Delivers autonomy in the target zone of 83 hours 29 minutes. No defrosting is required and the thermostat function/setting does not affect the freeze protection.

Vetted performance Findings of manufacturer evaluations or independent testing centers

No testing has been completed.

Testing organizations Independent lab, academic research centers, etc.

Third party tested prior to WHO pre-qualification by the Danish Technological Institute.

Safety Potential hazards / risks related to operation of this product

Vaccination is important to control the spread of diseases. However, compromised vaccine efficacy can occur when appropriate actions are not taken to account for temperature changes.

Complementary technical systems Performance of this product is improved with another technology (eg. Cookstoves and Wind-blocking skirts)

SunDanzer provides all of the equipment, tools and instructions needed to install the vaccine refrigerator. The kit comes complete with 4 solar panels, a compass, PV wiring, a universal solar panel mounting kit for roof mounting, grounding kit, 2 vaccine organization storage baskets, temperature display, a user and technician’s manual.

Compliance with regulations Product certifications and standards referenced by designer/manufacturer

Meets WHO/PQS/E003/RF05-VP.2 Standard.

Evaluation methods Evaluation methods/protocols/guidelines referenced by designer or manufacturer.

WHO pre-qualification testing established a minimum solar radiation reference period below which the product should not be used and the maximum autonomy that the product can achieve. PQS specification E003/PV01.2 specifies a compatible Type 2 solar power system. Three temperature zone designations are described: moderate zone, temperate zone and hot zone. In addition appliances are tested to establish a minimum rated ambient temperature designation.
