Preserving perishables in some of the world's most challenging conditions

Promethean Power Systems designs and manufactures refrigeration systems for cold-storage and milk chilling applications in off-grid and partially electrified areas of developing countries.

Our goal is to enable village-level chilling with a range of products that deliver high-quality produce to our customers. What excites us the most is that not only is this a great market need but also a win-win-win opportunity: a way to make a positive impact on quality and costs with dairy processors, better quality products for consumers, and increased opportunities for farmers in villages across India.
