HB Products shows test rigs with valves and sensors and a cold room cell whose screen displays a live refrigeration diagram, next to a condensing unit labelled "[CF] NEO2". Hanging blue banners list "Defrost of evaporator", "Oil sensors" and "NH3 sensors", with a green ring announcing "Zero super heat control – Now CO2 ready".
