This document discusses a case study of NXTCOLD refrigeration technology installed at a cold storage facility. The objectives of the case study were to determine any demand and energy savings from the new technology compared to the baseline system. It also aimed to assess the overall feasibility of the technology for cold storage applications and identify potential operational benefits. The document contains images of a typical central engine room, factory floor, trailer pod, and evaporator components of the new distributed refrigeration system.
