International solar refrigeration

Supporting healthcare centres across the globe

Keeping vaccines and blood donations cool is a major public health concern across the developing world. Recognising the challenge faced by medical professionals, Dulas pioneered solar vaccine refrigerators in 1982, and has been a market leader in the technology ever since. Fulfilling stringent PQS standards set by the World Health Organisation, these refrigerators offer safe blood and vaccine storage in the cold chain and are essential for use in areas with limited electricity availability.


Supporting healthcare centres across the globe

Drawing on our three decades of experience in the solar refrigeration industry, the Dulas range of solar direct drive refrigerators are designed to be the most reliable vaccine storage solutions available on the market today. Our sophisticated control systems optimise performance in real world conditions, alleviating functionality concerns through rainy or dull periods. These conditions prove the worth of Dulas’ SDDs. Our refrigerators excel even on cloudy days and in fluctuating light levels.
