Promethean’s Cold Storage Solutions (CSS) is the most economical way to chill, store and transport fresh fruits, vegetables and other perishables. Chilling the fresh produce immediately at the source is the most optimal solution to India’s cold-storage challenge. This stationary cooling system can chill farm produce under erratic grid conditions without requiring a diesel generator. At the heart of the CSS is Promethean’s Thermal Storage System that can store and release large amounts of thermal energy and can be applied to various cooling applications.
