This architectural drawing is Elevation plan of cold chamber and cold rack or cooling rack. In this plan showing local area of chamber, alucobond screen, glass door etc. Cold chambers built exclusively for power train testing are quite rare, since much of the research work in cold starting and operation in extreme environments tends to be carried out in whole vehicle systems. However, specialist research by companies involved in battery, lubricant, and materials research has climatic cells with controlled environments in the range between +40 and −40 °C. In this work truss is used. For more details and information download the drawing file.
