Coolers, Water Tube, Air
Louisville Dryer Company water tube cooler is an indirect type heat exchanger similar to the steam tube dryer. Instead of steam filled tubes, the tubes are flooded with water. Heat is transferred from the materials that is moving through the cooler and tumbling over the tubes to the water inside the tubes. The water tube cooler is generally more efficient than air coolers. They also do not require air handling equipment as part of the process.

The Louisville rotary air cooler is designed similar to the direct fired dryer, but instead of heated air, ambient air is used. Heat is transferred from the material moving through to the ambient air. Louisville rotary air coolers operate in a counter current flow for better thermal efficiency.
