In an effort to control the onset of unwanted condensation, MéCour developed a simple removable front and top cover for the 35-plate unit made specifically for the Thermo Spinnaker system. It protects against environmental impact on the exposed interior thermal walls of the plate stacker. The overall cover is comprised of separate front and top covers that are easily removed by hand, or the gripper can remove the top cover. The front cover will not interfere with the gripper access to plates, as the sides remain clear and open for gripper to retrieve plates. The plate stacker is designed to operate at 0°C .
