Sigma & Promethean

Promethean Power Systems designs and manufactures refrigeration systems for cold-storage and chilling in off-grid and partially electrified locations. Global food company, Sigma, manages a fleet of over 4,000 vehicles that service 210 distribution centres and 640,000 points of sale in 18 countries. Together, they are field testing a solution that converts electrical energy into cold energy, without the need to mount a condensing unit on a refrigerated vehicle/reefer truck, with the aim of reducing diesel fuel consumption, as well as food losses from poor temperature-control.
