The condenser is of bare-tube construction on the LBN-4 through –8 to reduce the amount of maintenance required, and fin-and-tube construction on the LBN-10. To keep the cabinet at top efficiency, periodic cleaning is required. To ease in the cleaning of the bare-tube condenser, the top of the condenser shroud is removable. - Page 9 are gravity-cooled cabinets. The sidewalls have refrigeration tubing in them to cool the lower portion of the interior and there is an upper evaporator that drops cold air down onto the product. The upper coil is equipped with defrost heaters that defrost the coil.
